Double-cone low-consumption anti-abrasion hydraulic cyclone separator

Abstract

The invention discloses a double-cone low-consumption anti-abrasion hydraulic cyclone separator, and relates to a cyclone separator. A separator shell is composed of a cylinder cavity shell and a cone cavity shell, an overflow outlet is vertically formed in the center of the top, a tube inlet is formed in the edge of the top in the tangent direction, an underflow outlet is formed in the bottom, an inner cone is fixed in the separator shell through a fixing fin, and an upper end opening is not higher than the lower end of the overflow outlet; the inner cone is designed according to a zero-axial-speed enveloping surface of the hydraulic cyclone separator; an injection-compression anti-abrasion assembly comprises a plurality of injection-compression channels which are evenly arranged outside the separator shell in a communicating mode, and a continuous phase with pressure is injected into the separator shell through the injection-compression channels. According to the double-cone low-consumption anti-abrasion hydraulic cyclone separator, the inner cone is inserted into the zero-axial-speed enveloping surface of the hydraulic cyclone separator, the inner cyclone and the outer cyclone are separated to prevent mutual interference of fluid, the injection molding anti-abrasion assembly is arranged to weaken collision abrasion of solid particles, and separation energy consumption and abrasion are reduced under the condition that the separation efficiency is guaranteed.

Description

technical field [0001] The invention relates to a cyclone separator, in particular to a double-cone low-consumption and anti-wear hydraulic cyclone separator, which belongs to the technical field of cyclone centrifugal separation. Background technique [0002] Hydrocyclone separators are widely used in various two-phase or multi-phase separation processes such as petrochemical, mineral processing, and life sciences. In the separation of solid-containing heterogeneous multiphase flow, the wear of solid particles on the wall of the hydrocyclone is very serious. At present, there is no other anti-wear method except for increasing the rigidity of the material of the hydrocyclone and adding a wear-resistant lining. [0003] In addition, during the separation process, the internal flow field of the hydrocyclone is violently turbulent, the transition of the external swirl flow and the internal swirl flow interferes with each other, and the existence of circulating flow and short-ci...
