Scope of application
It is suitable for water quality treatment and control of raw water and supplementary water, such as oil fields Drilling, trenchless horizontal directional crossing, mud purification cyclone separation for coal bed methane drilling, sand removal from river water and well water, coal washing water, industrial mineral processing, solid-liquid separation, liquid degassing and separation of immiscible liquids, etc.
Widely used in water source heat pump systems, heating water, central air conditioning cooling water, chilled water, steel, power generation, chemical industry and other industrial and mining enterprises, tap water, sea water, surface water, underground water, etc.
The cyclone of the desander is divided into two materials: one is high wear-resistant polyurethane material, and the other is made of high chromium cast iron. The high chromium cast iron material is made of stainless steel inlet and outlet (overflow Tube conical ceramic cyclone, conical stainless steel tank (the tank has two observation mirrors, automatic control or manual sand discharge valve (usually equipped with two sand discharge valves, backwash water valve, etc.). Its advantages are economical, affordable, high temperature resistance , the disadvantage is that it is not wear-resistant and has a short service life. It generally needs to be replaced once every hour. The polyurethane material is composed of three parts: volute, cone, and cone. Its advantages are wear resistance, the service life can be as long as hours, and the swirl effect is relatively Better

When it works, the potato emulsion (starch milk) is pumped into the desander cyclone and rotates at high speed in the desander. Due to the action of centrifugal force, the lighter materials ( Starch) is discharged through the overflow pipe, and heavier materials (sand, etc.) are discharged downward from the bottom along the inner wall of the conical swirl tube under the action of centrifugal force. The downward swirling sand is collected in the sand collecting hopper. It is discharged by manual or automatic sand discharge valve.
