  • What is the slurry pressurized balanced shield?

    The slurry pressurized balanced shield means that a partition is set in front of mechanical shield to form a slurry compartment between the partition and the cutterhead. The stability of excavation face is achieved in this way: feed mud into the slurry compartment, form a waterproof mud film with mud on the excavation face, and maintain water pressure by the tension of mud film to balance soil pressure and water pressure on the excavation face. The soil and sand excavated are transported to the ground in the form of mud and are separated by slurry treatment equipment. The separated slurry is adjusted in specific gravity and then transported to the excavation face.

    KD series slurry separation system mainly consists of scalping shaker module, desander module and desilter module. As a pre-screener, the scalping shaker can remove coarse particles from mud. The desander module is equipped with desander (primary cyclones) and fine-mesh shaker and mainly removes granulated sand. The desilter module is equipped with desilter (secondary cyclones) and can conduct a fine separation selectively according to the field needs of customers.

    Mud closed-loop circulating purification mode and lower water content in slags help reduce the environmental pollution. Equipment parts of the system are of anti-corrosion and wear-resistance, long service life and low failure rate, and the system can be suitable for various severe working conditions.

  • How to adjust the apex of KOSUN desander to achieve an optimum spray angle?

    The spray pattern varies in response to the feed head (inlet pressure), feed rate and cyclone apex opening. To maximize overall desander efficiency, the spray pattern of each cone must be balanced for optimal performance. This is done by observing the lower discharge pattern and then adjusting the apex opening to achieve the correct discharge angle for the prevailing feed rate and inlet pressure. The spray patterns of cyclone underflow are adjusted through changing orifice nuts with different diameters.


     
    Ideally, the spray angle of underflow is between 20° and 30°. When the spray angle is greater than 30°, a hollow center is formed. In normal operation, this pattern is undesirable. This spray pattern indicates that the exit diameter of the apex is too large, and an excessive amount of liquid discharges along with the solids flowing from the bottom of the cone. Correct this condition by using an orifice nut with a smaller diameter.


     
    When the spray angle is less than 20°, a hollow center is formed. In normal operation, this pattern is undesirable. This spray pattern indicates exit diameter of the apex is too small, the solids discharge is too dry, and excessive solids are being discharged with the liquid from the upper discharge. Correct this condition by using an orifice nut with a bigger diameter.

  • What are the ways for sludge recycling?

    As people are paying more attention to sustainable economic development, the resource utilization of treated sludge has also attracted more and more attention. In recent years, with the development of China's economy and the unceasing advancement of urbanization, urban sludge has gradually increased. The traditional methods are sludge landfill, sludge farming and sludge incineration. But the sludge landfill will cause some environmental problems. In order to meet the three principles of “harmlessness”, “reduction” and “recycling” in sludge treatment, the sludge low-temperature wall-breaking carbonization treatment technology is adopted to fully realize the resource utilization of sludge.


     
    The sludge low-temperature wall-breaking carbonization process can recover about 80% of the organic energy in the sludge, and produce biochar with a wide range of applications. Compared with other technologies on the market, it realizes the resource utilization of sludge, and veritably makes waste profitable. The main use values of its final products are reflected in: (1) floor brick, tray and other general construction raw materials; (2) green fuel, which can be used for heating of the system itself, coal-fired thermal power plant, garbage incineration plant, etc.; (3) improvement of land hardening, which can help to quickly restore the saline-alkali land into a good field; (4) new adsorbing material – activated carbon, which features in fast adsorption, outstanding adsorption and balance capacity; (5) being partly used as snow melting agent, which can facilitate road cleaning; (6) straw can be used as paper pulp; (7) kitchen waste can be used as high-value biomass charcoal.
     

    Sludge low-temperature wall-breaking carbonization technology can not only solve the adverse impact of sludge on the environment, but also solve the problem of land occupation by sludge, and turn waste into treasure, which is more in line with ecological and sustainable development strategy!

  • Some basic knowledge about heavy metal pollution in soil

    In recent years, China's emphasis on soil remediation, namely soil ecological environment improvement and soil pollution control, is obvious to all. Soil pollution is concealed and lagging, while soil pollution control and soil remediation are undoubtedly faced with complex pollution components and high technical thresholds. Especially, the soil contaminated by heavy metals is easy to accumulate, difficult to transfer, and has a high level of hazard.


     
    Originally, ecology is a whole, and soil contamination prevention needs to clear obstacles from all aspects and overcome difficulties. For example, the standards in the field of soil remediation are not perfect, and experts have been researching, discussing and compiling updated standards. Not long ago, the China Association of Environmental Protection Industry (CAEPI) just convened the group standard review meeting on “General Rules of Green Sustainable Restoration of Polluted Lands”, which was unanimously approved.


     
    It is undeniable that the treatment of heavy metal pollution in soil still has problems such as lack of large-scale treatment, insufficient technical reserves, ambiguous technical routes, inadequate demonstration or popularization experience, but the growth rate is still gratifying. It has been predicted that the soil remediation will release nearly CNY500 billion in the market during the “13th Five-Year Plan” period. Heavy metal pollution remediation is the focus of the market space, and the market investment that can be attracted has been foreseen evidently.
