Desilter

How should the desander and desilter in the mud circulation system be reasonably combined and used

发表评论 / Industry Update /

Domestic large-scale slurry circulation system manufacturing enterprises generally have the ability to design and produce cyclone desanders and slurry desilters (collectively referred to as solid control cyclones). The core performance index of the solid control cyclone is the separation particle size, which is usually represented by D50. The lower the D50 value, the better the separation effect. In terms of quality, the wear resistance of the cyclone is of vital importance. Currently, mainstream products mostly use polyurethane or high-chromium cast iron materials to ensure a longer service life.

Vertical cyclone desilter

发表评论 / 未分类 /

The vertical cyclone desilter is a highly efficient solid-liquid separation device, mainly used to remove fine sludge, suspended solids and other low-density solid particles from liquids. It is widely applied in industries such as oil drilling, mining and mineral processing, sewage treatment, and chemical engineering. Compared with the desander cyclone, the desilter is more focused on handling finer particles (typically 5-74m), and is suitable for scenarios such as slurry purification and liquid refinement. ​ Working principle of vertical cyclone desilter: The liquid-mixed mud and sand enter the cyclone tangentially. Under the action of the centrifugal force generated by high-speed rotation, the denser mud particles are thrown towards the wall of the cyclone and slide down along the cone

Solutions for Four Common Underflow Problems of Cyclone

READ: When cyclone works, high-speed swirling movement generates the air column and low-pressure area, creating suction towards underflow outlet. This cyclone is often found in mud cleaners where solid-content fluids enters and solids leave through underflow outlet. When cyclone works, high-speed swirling movement generates the air column and low-pressure area, creating suction towards underflow outlet. Inject some water into cyclone by certain pressure and adjust the outlet till it allows no fluid flow, meaning it reaches the balance point.

Desander and Desilter in Solids Control System

发表评论 / Industry Update /

As two indispensable equipments in the solid control system of oil and gas drilling, desander and desilter are responsible for separating the small solids in the drilling fluids which has been treated by the shale shaker and vacuum degasser. The desander takes care of the solid with diameter 45~74m, and 15~44m for desilter. Normally desander are mounted on the top of the first mud tank together with shale shaker s and vacuum degassers, while desilters are mounted together with centrifuges. Sometimes to save the top area of the mud tank, desander and desilter are combined together to work as high efficient mud cleaner. Desander and desilter are consist of hydrocyclones, high pressure flow pipes and a small shale shaer at the bottom. For desanders and desilters, only one vibration motor is u
