Multistage parallel hydrocyclone capable of regulating flow velocity

Abstract

The invention discloses a multistage parallel hydrocyclone capable of regulating flow velocity. The multistage parallel hydrocyclone comprises a rack body and a cyclone cylinder, wherein the inner cavity of the cylinder is divided into a solid-liquid separation cavity provided with a liquid inlet and a solid outlet cavity by virtue of a transverse separator; an upper end cover and a conical joint are respectively arranged at the upper and lower ends of the cyclone cylinder; the hydrocyclone also comprises multiple cyclones consisting of at least one cyclone cylinder provided with a longitudinal cutting seam, an overflow pipe and a packing bushing provided with multiple radial threaded holes; the upper end of the cyclone cylinder is fixedly inserted into the upper end cover, and the lower end of the cyclone cylinder penetrates through the transverse separator; the overflow pipe is inserted into the cyclone cylinder, an annular cavity is formed between the overflow pipe and the cyclone cylinder, a flange plate which is fixedly connected with the upper end cover in a detachable manner is fixedly arranged on the overflow pipe, and a positioning hole is formed in the outer side surface of the flange plate; the packing bushing is arranged in the annular cavity and is fixedly connected with the overflow pipe by virtue of a screw; the hydrocyclone further comprises a manifold structure consisting of a total joint and multiple pipelines. According to the hydrocyclone, different liquid production capacity conditions are met by virtue of the number of the started cyclones, and the flow velocity of the oil-gas mixed solution entering the cyclone cylinder is changed by changing the vertical position of the packing bushing, so that a good solid-liquid separation effect is achieved.

Description

technical field [0001] The invention belongs to hydrocyclone equipment for purifying crude oil mined underground, in particular to a multi-stage parallel hydrocyclone with adjustable flow velocity Background technique [0002] Crude oil produced underground is generally accompanied by a large amount of natural gas and other impurities (sand, water, etc.), which will not only make transportation difficult, corrode oil pipelines, and aggravate equipment wear, but more importantly, it will cause damage to refineries and chemical plants. production is difficult. Therefore, the oil and gas produced from the bottom of the well must be purified on the oil field. [0003] For a long time, the separation process in oilfield surface engineering mainly adopts gravity separation process. This conventional production process generally has problems such as many large-scale equipment, large floor space, high engineering cost, unsealed process, and insufficient utilization of system press...

AI Technical Summary

Problems solved by technology

[0006] The existing static cyclone has the advantages of convenient operation, small equipment investment, small footprint, simplified process flow, low operating cost, etc., but at the same time, it also has disadvantages such as low separation efficiency and inability to adapt to complex and changeable working conditions.
