Energy-saving diversion type cyclone separator

Abstract

The invention discloses an energy-saving diversion type cyclone separator. The energy-saving diversion type cyclone separator comprises a cyclone separator body; the cyclone separator body comprises an upper cylindric section and a lower conical section; the bottom of the conical section is provided with a sewage draining outlet; the top of the cylindric section is provided with an overflow opening; the sidewall of the cylindric section is equipped with a liquid inlet; the liquid inlet is provided with a liquid inlet pipe; the end, close to the cylindric section, of the liquid inlet pipe is provided with a connecting section; the connecting section is arranged to be downwardly oblique; a neck bush is sleeved by the conical section; and the inner wall of the neck bush is provided with a spiral flow deflector used for diverting outer descending eddy flow. The energy-saving diversion type cyclone separator provided by the invention can divert outer descending eddy flow and prevent solid particles from being brought away by inner ascending eddy flow, so separation effect is improved; and the energy-saving diversion type cyclone separator has the advantages of small pressure drop and energy conservation.

Description

technical field [0001] The invention belongs to the technical field of centrifugal separation equipment, and in particular relates to a cyclone separator. Background technique [0002] Cyclone separator, also known as hydrocyclone, is a device that uses the principle of centrifugal sedimentation to separate solid particles from suspended matter. The main body of the cyclone separator is composed of a cylinder and a cone. The suspension enters the cylinder through the inlet pipe along the tangential direction, and makes a spiral motion downwards. The solid particles are thrown to the wall of the vessel by the inertial centrifugal force, and fall to the outlet at the bottom of the cone with the downward swirling flow, and are discharged from the bottom. The clear liquid or the liquid containing microparticles becomes the rising inner layer swirl and is discharged from the central tube at the top, which is called overflow. There is an air column under negative pressure in the...

AI Technical Summary

Problems solved by technology

[0003] Although the existing cyclone separator can meet the use requirements to a certain extent, at the bottom of the cone near the outlet, the descending swirl close to the inner wall of the cone is discharged from the outlet, while the rising inner swirl is generated here , and the inner swirl may affect the descending swirl of the outer layer, which will cause the solid particles in the descending swirl of the outer layer to be carried to the upper overflow port by the inner swirl, which will lead to poor separation effect of the swirl. question
