  • What factors affect the performance of the horizontal screw centrifuge?

     
    The horizontal screw centrifuge mainly consists of a drum, a screw, a differential system, a liquid level baffle, a drive system and a control system, etc. It is a dedicated solid-liquid separation equipment designed in accordance with the characteristics of petroleum drilling fluid. It can complete various processes such as feeding, centrifugal sedimentation and unloading at full speed. It is mainly used for recovering barite, removing fine solids, reducing the solid content of drilling fluid, controlling the density and viscosity of drilling fluid, ensuring the performance of drilling fluid and playing an important role in rapid drilling. The LW series centrifuge separates drilling suspensions based on the principle of centrifugal sedimentation. The suspension enters the drum through the liquid outlet hole in the screw conveyor via the feed pipe. Under the action of centrifugal force, solid particles are pushed to the inner wall of the drum and discharged from the small end of the drum through the blades on the screw conveyor. The liquid phase overflows through the overflow hole at the large end of the drum. This cycle is repeated continuously to achieve the purpose of continuous separation. The sedimentation centrifuge belongs to the category of horizontal screw centrifuges, and its full name is horizontal screw sedimentation centrifuge.

     

     

    Factors affecting the performance of horizontal screw centrifuges
     
    The application effect of the horizontal screw centrifuge is influenced by the mechanical part, which can be divided into adjustable factors and non-adjustable factors. The following is an explanation of each. First, by understanding its working principle, it can be effectively controlled during use
    The non-adjustable mechanical factors include: the diameter of the drum and its effective length. Semi-cone Angle of the drum. Pitch. Spiral type. The following classification is explained: Drum diameter and effective length: The larger the drum diameter, the longer the effective length, the larger the effective settlement area, and the greater the processing capacity. The semi-cone Angle of the drum: When the sediment settled on the inner side of the centrifuge drum is pushed towards the discharge port along the conical end of the drum, it is subjected to a downward sliding reflux force due to the effect of centrifugal force. The semi-cone Angle of the drum: A relatively important parameter in the design of centrifuges. In terms of clarification effect, the cone Angle should be as large as possible. In terms of slag conveying and dewatering effects, the cone Angle should be as small as possible. Pitch: that is, the distance between two adjacent helical blades, is a very important structural parameter and directly affects the success or failure of slag transportation. When the diameter of the helix is constant, the larger the pitch and the greater the helix Angle, the greater the chance that the material will get clogged between the helix blades. At the same time, a large pitch will reduce the number of turns of the helical blade, resulting in uneven material distribution at the conical end of the drum and causing increased machine vibration. Therefore, for difficult-to-separate materials such as activated sludge, the conveying of the residue is rather challenging, and the pitch should be smaller. Spiral type: According to the different ways of relative movement of liquid and solid within the drum, it is divided into counter-flow type and co-flow type. The feeding chamber of the counter-flow centrifuge is located in the middle of the screw, that is, near the boundary between the drying zone and the sedimentation zone, to ensure that the liquid phase has sufficient sedimentation distance, but the solid phase can only stay for the time it needs to pass through the conical part, so a relatively high centrifugal force is required. When materials enter the drum from here, the solid particles that have already settled in this area will float up again due to disturbance, and turbulence and additional vortices will also be generated, reducing the separation effect.
     
    2. Adjustable mechanical factors include:

     

    drum speed, differential speed (differential ratio), liquid ring layer thickness, and process factors. The following is a classification explanation: Drum speed: The adjustment of drum speed is usually achieved through a variable frequency motor or a hydraulic motor. The greater the rotational speed, the greater the centrifugal force, which is conducive to increasing the solid content of the mud cake. However, if the rotational speed is too high, the sludge flocs will be destroyed, which will instead reduce the dewatering effect. At the same time, higher rotational speeds have higher requirements for materials, increase the wear and tear on the machine, and the power consumption, vibration and level will also increase accordingly. Differential velocity (differential ratio) directly affects the sludge discharge capacity, the dryness of the sludge cake and the quality of the filtrate. Increasing the differential velocity is beneficial for enhancing the sludge discharge capacity, but the dewatering time of the sediment will be shortened, and the moisture content of the sludge cake after dewatering will be high. At the same time, excessive differential velocity will increase the disturbance of the screw to the liquid pool in the clarification zone, and the quality of the filtrate will be relatively poor (commonly known as "backmixing"). The thickness of the liquid ring layer: The thickness of the liquid ring layer is an important parameter for equipment optimization, directly affecting the effective sedimentation volume of the centrifuge and the length of the drying zone (shore zone), and thereby influencing the treatment effect of sludge dewatering. Generally, it is achieved by manually adjusting the height of the liquid level baffles when the machine is shut down. During adjustment, it is necessary to ensure that the heights of all liquid level baffles are consistent; otherwise, it will cause severe vibration during the operation of the centrifuge. An increase in the thickness of the liquid ring layer will expand the sedimentation area, and the residence time of the material in the machine will also increase accordingly, improving the quality of the filtrate. However, at the same time, the length of the drying zone (shore zone) within the machine will shorten, resulting in a decrease in the dryness of the mud cake. On the contrary, reducing the thickness of the liquid ring layer can achieve a higher solid content in the mud cake, but it comes at the expense of the quality of the filtrate. Process factors: To improve the dewatering performance of sludge, an appropriate amount of organic high-molecular flocculants, such as polyacrylamide (PAM), should generally be uniformly added before mechanical dewatering to reduce the specific resistance of the sludge, making it easier to dewater after the separation of the solid and liquid phases of the sludge. The type of flocculant must be compatible with the characteristics of the sludge, as well as the type of equipment and operating conditions. In many cases, the reagents that perform well in the beaker test for flocculant selection do not have better performance in practical applications. A very important reason for this is that although the characteristics of the reagents to some extent meet the characteristics of the sludge, they cannot fully meet the operating conditions of the equipment.
     

    There are many factors that affect the dewatering efficiency of the horizontal screw centrifuge, and these factors interact with each other. Therefore, the treatment effect is the result of the combined action of the above-mentioned factors. The selection of the centrifuge should be based on the actual situation of the engineering project, and the adjustment of operating parameters should comprehensively consider factors such as the expected moisture content, solid content and economy of the dewatered mud cake as required by the disposal method of the dewatered mud cake.

  • Innovation and application of vertical cuttings spin dryrs, key equipment in the oil drilling industry

     
    Oil drilling, as a globally significant energy resource, faces numerous challenges during the extraction process. During the drilling process, a large amount of drilling cuttings are produced. These cuttings are usually mixed with drilling fluid. If not handled properly, it will not only cause waste of resources but also cause serious pollution to the environment. As an advanced solid-liquid separator, the vertical cuttings dryer plays a crucial role in the oil drilling industry. It can effectively process drilling cuttings, achieving the recycling and reuse of drilling fluids and the standard discharge of cuttings. It can effectively handle drilling cuttings, achieving the recycling of drilling fluid and the standard discharge of cuttings. With the continuous growth of global energy demand and increasingly strict environmental protection standards, it is of great practical significance to have a thorough understanding of the working principle and performance advantages of vertical cuttings dryers and their application in the oil drilling industry.

     

     

    I. Overview of Vertical Rock Cuttings Spin Dryer
     
    1. Working principle
     
    This equipment utilizes centrifugal force to achieve efficient separation of drilling cuttings and drilling fluid. During operation, the drill cuttings mixture enters the high-speed rotating drum. Under the action of centrifugal force, the denser cuttings are thrown towards the drum wall and scraped off by the scraper, while the drilling fluid accumulates towards the center and is discharged from the overflow outlet. This method features high separation efficiency and large processing capacity, which can meet the rapid and precise demands of solid-liquid separation in the oil drilling industry.
     
    2. Structure
     
    Vertical cuttings spin dryers are typically composed of rollers, scrapers, drive units, frames and control systems. The drum is the core component of the equipment. Its material is generally made of high-strength and wear-resistant materials to withstand the huge centrifugal force and rock debris wear during high-speed rotation. The scraper is installed inside the drum. Its function is to promptly scrape off the rock debris adhering to the inner wall of the drum, ensuring the normal operation of the equipment and the separation effect. The drive unit provides power for the rotation of the drum. Generally, high-performance motors and transmission systems are adopted to achieve smooth and high-speed rotation of the drum. The frame plays a role in supporting and fixing each component, ensuring the stability of the equipment during operation. The control system is used to control the start-up, stop, speed regulation and other operating parameters of the equipment, to achieve the automatic and intelligent operation of the equipment, and to improve the operational efficiency and reliability of the equipment.
     
    3. Performance characteristics
     
    Efficient solid-liquid separation
    The vertical cuttings spin dryer has excellent solid-liquid separation capabilities and can effectively separate drilling fluid from drilling cuttings. This equipment was designed and manufactured with full consideration of the harsh environment and high-load operation requirements of oil drilling operations. It adopts high-quality materials and advanced manufacturing processes to ensure high reliability and stability. In practical applications, many oil drilling enterprises have reported that the vertical cuttings spin dryer can still maintain a good working condition after continuous operation for thousands of hours, providing a strong guarantee for the smooth progress of drilling operations. Easy to operate and maintain

     

     

    Ii. The Key Role of Vertical Cuttings Dryers in the Oil Drilling Industry
     
     
    Reduce waste emissions
     
    During the process of oil drilling, a large amount of drilling cuttings and waste drilling fluid are directly discharged without effective treatment, which will cause serious pollution to the surrounding environment. Vertical cuttings dryers can effectively separate drilling fluids from cuttings, reduce the water and oil content of cuttings, and thereby decrease the overall waste discharge. The oil content of the processed rock cuttings can be as low as less than 5%, meeting international environmental protection standards and significantly reducing the risk of pollution to soil, water and other environments.
     
    2. Reduce pollution to soil and water
     
    The traditional methods for handling drilling waste are prone to causing harmful substances to seep into the soil and water bodies, resulting in long-term damage to the ecological environment. The vertical cuttings dryer separates harmful substances from cuttings in drilling fluid through efficient solid-liquid separation, preventing these substances from causing damage to soil and water. The vertical cuttings dryer effectively separates harmful substances in the drilling fluid from the cuttings through solid-liquid separation, avoiding direct pollution to the soil and water. Meanwhile, the recovered drilling fluid can be reused after further processing, reducing the usage of new drilling fluid and indirectly lowering the potential pollution risk to the environment.
     
     
    3. Recovery and reuse of drilling fluid
     
    Drilling fluid is an important consumable in oil drilling operations, and its cost accounts for a large proportion of the total drilling cost. Vertical cuttings dryers can effectively recover drilling fluid from drilling cuttings. After appropriate treatment, the drilling fluid can be reused in drilling operations. Generally speaking, a large amount of drilling fluid can be recovered by using this kind of equipment, and the recovery rate can reach a certain percentage.
     
    4. Ensure the continuity of drilling operations
     
    In drilling operations, if drilling cuttings are not dealt with in a timely manner, they will accumulate, affecting the normal operation of drilling equipment and even causing safety accidents. The vertical cuttings dryer can continuously and stably process drilling cuttings, ensuring the continuity of drilling operations. The vertical cuttings dryer provides continuous and stable cuttings treatment, ensuring the continuity of drilling operations. The high reliability and stability of the equipment enable it to maintain a good working condition for a relatively long time, reducing the downtime caused by equipment failures.
    Vertical cuttings spin dryers play a crucial role in the oil drilling industry. It not only complies with increasingly strict environmental protection regulations, reducing waste emissions and pollution to soil and water, but also effectively lowers costs through the recycling and reuse of drilling fluids and the reduction of waste treatment costs. Meanwhile, its rapid processing of drilling cuttings ensures the continuity of drilling operations, which can significantly improve drilling efficiency, reduce flammable and explosive substances, lower the risk of equipment failure, and enhance overall operational safety.

  • Hot washing process of oil sludge: A key technology for environmental protection and resource regeneration in oil fields

    The rapid development of the petroleum industry has brought about a thorny problem: oily sludge. These black pollutants produced during the processes of oil extraction, transportation and refining contain a large amount of toxic and harmful substances. They not only damage the structure and ecological functions of the soil, but also may pollute groundwater and threaten human health.
     
    The traditional incineration and landfill treatment methods are not only inefficient but may also cause secondary pollution. Facing the increasingly severe environmental protection situation, oilfield enterprises urgently need an efficient, environmentally friendly and economical solution.
     
    The hot washing process of oil sludge is an efficient and environmentally friendly technology for treating oil sludge. It achieves the reduction, harmless treatment and resource utilization of oil sludge by heating, washing and separating the oil sludge, thus separating the oil, water and solid substances in the oil sludge.

     


     

    The hot washing process flow of oil sludge mainly includes the following steps:
     
    1. Vibrating screen pretreatment: Screen the oil sludge to be treated to remove large particle waste. At the same time, add spray water to make the oil sludge more moist, which is convenient for subsequent treatment.
    2. Mixing tank treatment: Put the sieved oil sludge into the mixing tank, add hot water and chemicals, and stir thoroughly. The agent can play a role in emulsifying, dispersing and dissolving the oil in the oil sludge, while hot water can increase the temperature of the oil sludge and accelerate the separation of the oil.
    3. Sedimentation tank separation: Put the stirred oil sludge into the sedimentation tank for sedimentation separation. During the sedimentation process, the oil in the sludge will float to the water surface, forming floating oil, while water and solid substances will settle at the bottom of the tank. Floating oil can be transported through pipelines to waste oil tanks for recycling and reuse, while water can be transported through pipelines to water tanks for recycling and reuse.
    4. Centrifuge separation: Place the sediment at the bottom of the sedimentation tank into a centrifuge for centrifugal separation. During the centrifugation process, water and solid substances in the sediment will be separated. The water can be transported through pipelines to the water tank for recycling, while the solid substances will be discharged and treated as waste residue.


     

    The hot washing process of oil sludge has the following advantages:
     
    1. Environmentally friendly and pollution-free: The entire treatment process does not produce waste gas, wastewater or waste residue, and will not cause secondary pollution to the environment.
    2. High resource utilization rate: The oil in the oil sludge can be recovered and reused, and at the same time, water and solid substances can be recycled, which improves the utilization rate of resources.
    3. Low processing cost: Compared with traditional oil sludge treatment methods, the oil sludge hot washing process has a lower processing cost and a higher cost performance.
    The hot washing process of oil sludge is an efficient, environmentally friendly, resource-efficient and low-cost oil sludge treatment technology. It can effectively solve the problem of oil sludge pollution and contribute to the sustainable development of the petroleum industry.

  • Xi ‘an KOSUN successfully delivered the renovation project of the vibrating screen mesh bracket for a domestic lake dredging project

    Following the successful delivery of a set of sludge treatment and screening system for the second phase of a large lake dredging project in early 2025 and receiving high recognition from the owner,
    Xi 'an KOSUN has recently taken on the key equipment upgrade task for the first phase of the project again – successfully completing the intelligent transformation of the vibrating screen mesh support
    frame and passing the owner's acceptance in one go The continuation of this technical collaboration marks that Kosun's technical strength and service quality in the field of environmental protection dredging have continuously won the trust of the market.
     
     
    The dredging project in this lake area has a processing capacity of up to 1,800 cubic meters per hour and requires continuous high-intensity operation for many years.
    Traditional vibrating screens are prone to problems such as deformation and cracking of the screen frame during long-term high-load operation, which affects the efficiency of silt removal.
    To break through this bottleneck, the project party conducted multiple rounds of on-site investigations and technical comparisons. Ultimately, Xi 'an KOSUN was selected to carry out a special upgrade and transformation of the existing equipment to enhance the screening efficiency and reduce maintenance costs.

     

              


     

    After a thorough analysis of the on-site working conditions, the Kosun technical team proposed three core renovation plans:
     
    1. Material upgrade: Low alloy high strength structural steel is adopted to replace the original carbon steel brackets, effectively extending their service life.
    2. Structural optimization: Change the type of screen mesh from the original small polyurethane screen mesh to large stainless steel strip seam mesh to reduce maintenance costs and decrease the workload of personnel.
    3. Static mechanical analysis: Adjust the structure of the screen mesh bracket through static mechanical analysis to effectively avoid cracking risks.

     

              

     

    This renovation not only solved the existing problems of the owner, but also provided a standardized renovation example for large-scale water area dredging projects.
    In the future, we will continue to output the "KOSUN solution". After the project is completed, it is expected to significantly improve the screening efficiency of the dredging project.
    Xi 'an KOSUN responds to the call of "Green mountains and clear waters" with technological innovation It demonstrates the social responsibility of environmental protection equipment enterprises.

    river dredging, mine tailings and other fields. Its independently developed vibrating screen series equipment is renowned for its high stability, and its service network covers more than 70 countries around the world.

     

     

  • The ＂golden pair＂ in the mud solid control system: the classification coordination mechanism of the desander and the centrifuge

    In the slurry solid control system, after the vibrating screen completes the separation of coarse particles, the coordinated action of the desander and the centrifuge becomes the key link to achieve precise classification of solid particles. Through different separation principles and classification treatments, the solid particles in the mud are efficiently separated by particle size, which not only ensures the stable performance of the drilling fluid but also significantly improves the utilization rate of resources and environmental benefits.
     

           

     

    I. Working Principles of Desander and Centrifuge
     
    Desander: Separation of medium particles under centrifugal force field
     
    Working principle: The solid-containing slurry enters the cyclone in a tangential direction. Under the centrifugal force field generated by high-speed rotation, the denser solid particles (76-47μm) are thrown towards the wall of the cyclone and discharged downward along the cone, while the liquid phase and fine particles are discharged from the central overflow pipe.
    Technical features: Processing capacity 50-200m³/h, separation efficiency depends on the feed slurry pressure (0.2-0.4MPa), cyclone diameter (8-12 inches), and sand discharge port size (1/4-1/2 inch).
     
    Centrifuge: Fine separation through ultra-high-speed rotation
     
    Working principle: The slurry enters the high-speed rotating drum (3000-5000 RPM), generating a strong centrifugal force to separate ultrafine particles (<15μm) from weighting agents such as barite. The liquid phase is discharged through the overflow port, and the solid phase is conveyed to the slag discharge port by the screw conveyor.
    Technical advantages: The separation accuracy can reach 5μm, the barite recovery rate exceeds 90%, and the material loss is significantly reduced.


     

     

    Ii. Synergistic Mechanism: "Classification – purification – circulation" in a trinity
     
    Classification treatment: The desander serves as the pretreatment unit
    The desander prioritizes the separation of medium particles larger than 74μm, which can reduce the processing load of the centrifuge by 30-50%. Data from a certain shale gas project shows that the processing capacity of the centrifuge after pretreatment has dropped from 150m³/h to 80m³/h, and the service life of the equipment has been extended by 20%.
     
    Deep purification: The centrifuge achieves fine control

     

    After being treated by the desander, the solid content of the mud was reduced to below 8%. The centrifuge further reduced the content of particles smaller than 15μm from 12% to within 5%, significantly improving the rheological properties of the drilling fluid.


     


     

    Resource recycling: A win-win situation for economic benefits and environmental protection
    The collaborative system can achieve a barite recovery rate of over 90%, and the moisture content of rock cuttings after dehydration is less than 30%. It can comprehensively reduce the cost of mud by 25-40% and cut the discharge of hazardous waste by more than 40%.
     
    Iii. Equipment Selection and Maintenance Guide
     
    Selection suggestions
    Desander: Polyurethane wear-resistant cyclone is preferred, and the processing capacity should cover the maximum drilling displacement (120%).
    Centrifuge: Select the dual-motor drive model based on the density of the slurry. The material of the drum needs to be corrosion-resistant
     
    Key points of maintenance
    Daily inspection: Cyclone wear condition, centrifuge vibration value
    Regular maintenance: Lubricate the bearings weekly and replace the seals monthly
    Anti-clogging measures: Install 100 front-mounted filters and configure an automatic backwashing device
     
    Hierarchical collaboration doubles efficiency
    The collaborative effect of the desander and the centrifuge is essentially an art of balancing "efficiency and precision". The former rapidly separates medium-sized particles through centrifugal force, while the latter achieves ultrafine purification through ultra-high-speed rotation. Both are indispensable. In the modern drilling field that pursues cost reduction, efficiency improvement and green low-carbon development, optimizing the collaborative mechanism of this "golden pair" will inject continuous vitality into the mud solid control system.

  • What are the specific types of KOSUN mud solids control system?

    KOSUN Mud solids control systems are mainly divided into three categories: skid-mounted drilling mud solids control systems, mobile drilling mud solids control systems, and low-temperature drilling mud solids control systems. Among them, the skid-mounted drilling mud solids control system for land drilling rigs manufactured by KOSUN adopts a multi-functional design, so that the whole solids control system can meet the requirements of different well depths and various drilling muds. It can operate independently or in combination. KOSUN can produce 350HP, 450HP, 550HP, 650HP, 750HP workover rig mud circulation system and 1000HP, 1500HP, 2000HP, 3000HP land skid-mounted drilling rig mud circulation system.
     
    mud solids control system
     
    The advantages of skid-mounted drilling mud solids control system are:
    ①Easy to install: The production and assembly of the skid-mounted drilling mud solids control system equipment are all completed in the factory, and the on-site installation workload is small. It only needs to complete the connection of the interface pipes and external electrical connections to work.
    ②Easy to migrate: Since the functional components are integrated into a whole base, it can be easily migrated as a whole.
    ③Compact design and small footprint: the skid-mounted drilling mud solids control system has a compact structure, which reduces the footprint compared with the traditional installation method.
     
    Mobile drilling mud solids control system:
    In order to meet the needs of modern oilfield drilling engineering time, increase moving speed and reduce costs, KOSUN combines the structural characteristics of mobile drilling rigs and skid-mounted modular drilling rigs to ensure safety, With the design concept of high efficiency and environmental protection, the mobile drilling mud solids control system has been developed, which greatly improves the automation degree of the solids control system. Field application shows that this type of system not only has the advantages of reasonable structure, compact design, safety and reliability, but also has incomparable advantages such as fast and convenient movement and wide range of use.
     
    Low temperature drilling mud solids control system:
    In order to meet the requirements of low temperature drilling conditions in polar regions (minus 40 degrees), KOSUN can produce low temperature drilling mud circulation systems suitable for special areas according to the specific requirements of customers. Therefore, a low-temperature drilling mud solids control system was developed. Features and advantages: low temperature resistance.
