Abstract

The invention relates to a technique for the separation of inhomogeneous liquid media and allows an increase in the degree of purification. A hydrocyclone consists of a body formed of cylindrical (C) 1 and -conical (c) 2 parts, tangential nozzle 3 inlets, drain 4 and sand 5 nozzles. C 1 is lined with ring 6, and K 2 is cone 7 with a variable angle of curvature, while cone 7 is formed by rotating the tang x tangential curve constructed from the radius of the larger diameter of the cone 7 down along the hydrocyclone axis. For a smooth transition from C 1 to K 2, the argument values are 30 X 90. During the operation of the hydrocyclone, the progressive increase in the tangential component of the flow velocity due to the variable curvature of the cone 7 leads to a more intense displacement of the particles of the solid phase to the wall. 1 il.

Description

The invention relates to the technique of separation of heterogeneous liquid media in hone centrifugal forces and can be used to clean the drilling fluid in the oil industry.

The purpose of the invention is to increase the degree of purification.

The drawing shows the proposed hydrocyclone, general view.

A hydrocyclone consists of a steel or cast iron body formed by a cylindrical 1 and a conical 2 tangential inlet 3, a drain 4 and a sand 5 pat, logging, lined with a high-hardwearing material, such as silicon carbide. The lining protects the cylindrical part by a ring 6 and a conical cone 7. In this case, the working surface of the conical part is made with a variable curvature. The design of the surface is a tangenoid at tgx, constructed from the radius of the larger diameter of the cone. For a more smooth transition from the cylindrical part of the lining to the surface with a variable curvature, the values of the argument X are set to 30-90.

The hydrocyclone operates as follows.

through the tangential inlet 3 enters the hydrocyclone. Under the action of centrifugal forces, the solid particles are thrown to the walls of the apparatus and removed through the sand pipe 5, and the purified fraction is removed through the pipe 4,

The progressive increase in the tangential component of the flow rate of the solution due to the variable curvature of the conical part of the body leads to a more intense pushing of the particles of the solid phase to the wall and carrying them through the sand pipe.
