A hydrocyclone is most often used to separate "heavies" from a liquid mixture originating at a centrifugal pump or some other continuous source of pressurized liquid. A hydrocyclone is most likely to be the right choice for processes where "lights" are the greater part of the mixture and where the "heavies" settle fairly easily.
The work principle of hydrocyclones is to separate two or several components with different densities with the aid of centrifugal force.
Desanderand desilter square measure consisted of hydrocyclones, high flow pipes and alittle sedimentary rock shaer at very cheap. For desanders and dust desilters, only 1 vibration motor is employed to drive the screen basket. whereas for top economical it'd would like 2 motors. There would be equipped with 2 10″ or 12″ iron hydrocyclones for desander even as the solids ought to be separated is comparatively massive, and embrace some sands within the mud.
The Desander works on the principle of centrifugation.forced by centrifuge, drilling mud run into hydrocyclones with certain velocity and pressure, and the gravity forces the larger particles down to the bottom and discharge from the outlet onto the shale shaker screens,while the lighter ones, due to the centrifugation, spiral up around the central core and flow into centrifuge(the 4th phase solids control equipment) to be further treated.
Cyclone bed cleaning device is the use of the working principle of centrifugal separation for bed cleaning, owing to the eccentricity of the inlet pipe installed in cylinder position of the main parts. After the rotation flow bed cleaning by water inlet pipe, first along the tangent direction around the cylinder form fluid around the inclined downward, rotating flow goes down.
KOSUN desander is the second class and the third class solid control equipment to treat the drilling fluid. According to the size of the cone diameter, it is divided into desander and desilter. Usually the cone diameter is more than 6″is called desander, and used as the second-control equipment in drilling operation. We commonly used 8 "and 10" cones desander to separate solid-phase particle size 47-76μm in the drilling fluids.
