Hydrocyclone New application of desanding Cyclone: the initial application of desander hydrocyclone is used in solid particles in sandblasting jet operation. In the process of small-scale desanding hydrocyclone, it is concluded that the oil attached to the solid surface can be removed. In the process of producing high gravity, cyclone desander will produce strong static shear field. In practical application, the effect of sand control is to reduce the sand content of wellhead from 16 to less than 1. The hydrocyclone oil-water separator was obtained as early as 1891, but it was not widely used in industrial production until after World War II. The first one is the application in mineral processing industry. Due to the different mineral processing conditions, extensive research on hydrocyclone has been collected, which makes the hydrocyclone from only used for rough separation to classification operation. It can be said that the whole mineral processing industry can not do without hydrocyclone. Later, hydrocyclones were used in chemical, petroleum, food, medicine, wastewater treatment and other industrial sectors.
Working principle of hydrocyclone desanding hydrocyclone: the basic principle of hydrocyclone desander is that the fluid is introduced into the conical shell of desanding cyclone in tangent direction by centrifugal force, and the solid phase is pushed to the cone surface by gravity, and then it runs downward along the surface to the discharge outlet of the separator. The secondary liquid swirl produced in the separator shell will produce upward movement force, and then be discharged from the discharge manifold through the cyclone detector. The smaller the diameter of the desanding cyclone, the greater the separation effect. Thus, the smaller the diameter of the cyclone is, the greater the separation effect will be. The cyclone oil-water separator is mainly used to remove more than 90% of the non chemical oil in water by the specific gravity difference of two immiscible liquids. The key component of hydrocyclone is hydrocyclone, which is composed of distribution port, swirl chamber, contraction chamber, tail cone, tail pipe, underflow port and overflow port. The oil-water mixture enters the cyclone tube through the distribution port of the swirl chamber and forms a spiral flow under a certain pressure difference. Through the contraction cavity and the tail cone, the fluid speed is increased and a stable centrifugal force field is formed in the hydrocyclone. According to Stokes law, the heavy phase water in the oil-water mixture is thrown to the inner wall of the cyclone tube under the action of strong centrifugal force, and is discharged from the underflow port in a spiral state, while the light phase oil forms an oil core in the hydrocyclone and is discharged from the overflow port to realize oil-water separation. The centrifugal field produces a centrifugal acceleration of 2000g, so the oil and water can be separated in a few seconds. It can be operated manually or automatically.
