A wear-resistant solid-liquid separation cyclone

Abstract

A wear-resistant solid-liquid separation cyclone. The main purpose of the utility model is to solve the problem that the lower wall surface of the outer cone section of the existing cyclone is severely worn and the service life is reduced. It is characterized in that: the upper closed end of the cyclone chamber is an arc-shaped top surface, and the overflow port is fixed on it after penetrating the arc-shaped top surface; the wear-resistant solid-liquid separation cyclone also includes the upper section of the outer cone, the outer The lower section of the cone, the bottom flow port and the small cone of the lining; the bottom of the upper section of the outer cone has an upper flange of the outer cone, and the top of the lower section of the outer cone has a flange of the lower section of the outer cone; the small cone of the inner lining is located on the outer cone There are several symmetrical elliptical sand discharge holes in the lower section of the outer cone, forming an inter-cone annular space with the inner wall of the lower section of the outer cone; at least two ribs are symmetrically fixed inside the lower section of the outer cone, and the ribs are along the outer The axial spacing of the lower section of the cone is distributed to support the small cone of the inner lining. The rib plate divides the annulus between the cones into at least two sand discharge channels; the annulus between the cones is connected with the bottom flow port.

Description

Technical field: [0001] The invention relates to a cyclone separation device applied in the field of multiphase medium separation treatment. Background technique: [0002] After the oilfield entered the high water cut period, the long-term water injection development caused the formation cementation to deteriorate. At the same time, the application of new technologies such as sand filling fracturing, polymer flooding and ASP flooding enhanced the sand-carrying capacity of fluid production, and some oil wells produced The sand is becoming more and more serious, and the sand buried in the oil layer or the sand stuck in the oil pump often appear. Sandy production fluid has become one of the important problems affecting the stable and increased production of oilfields. Efficiently separating the sand from the produced liquid before it enters the oil production pump is of great significance for improving pump efficiency, prolonging the life of the pump, improving the stability o...

Problems solved by technology

However, the above inventions are mainly through changing the structural shape of the cyclone or connecting the cyclone in series and parallel, such as adding an inner cone and changing the structure of the overflow port. Such a design will make it difficult to maintain and handle the equipment. If the cyclone is worn out, it will directly affect the cyclone. Flow life
