Which industries are drilling desander used in

Drilling desander is mainly used to remove solid particles in the bottom water and including the bottom hot water and other water sources. It is suitable for water source heat pump system, chilled water system, winter cooling and heating circulating water system, industrial cooling circulating water system, etc. It is widely used in many industrial sectors such as chemical industry, environmental protection, food, medicine and so on. In the field of water supply treatment, the effects of sand removal, turbidity reduction, and solid-liquid separation are significant. Its working principle is made according to the principle of screening when the solid particles in the fluid rotate in the desander, and then a new type of separation equipment combined with filtering measures.

When the water flow enters the equipment tangentially from the water inlet of the desander under a certain pressure, it produces a strong rotational movement. Due to the different densities of sand and water, under the action of centrifugal force, centripetal force, buoyancy and liquid drag, the low-density water rises and is discharged from the outlet. The denser sand is discharged from the sewage outlet at the point of the equipment and floats together along the water flow. Individual small particles are blocked by the secondary filter device to achieve the purpose of sand production.

The cyclone of the desander is divided into two materials: one is high wear-resistant polyurethane material, the other is high chromium cast iron material, and the high chromium cast iron material is made of stainless steel inlet, outlet (overflow pipe), cone It is composed of a shaped ceramic cyclone, a conical stainless steel tank (the tank has two observation mirrors), an automatic or manual sand discharge valve (usually equipped with two sand discharge valves), a recoil valve, etc. Its advantages are economical and practical. High temperature resistance, the disadvantage is that it is not abrasion-resistant and has a short service life. Generally, it needs to be replaced once in 2000 hours; the polyurethane material is composed of volute, cone and vertebral body. Its advantage is wear resistance, and the service life can be as long as 4200 hours. , The swirl effect is relatively good, but it is not resistant to high temperatures.

Desander are widely used in industrial sectors such as ground source heat pumps, water treatment, food, and medicine. Desanding of river water and well water, coal washing water, industrial beneficiation, solid-liquid separation, liquid degassing and separation of non-mutual liquids.
