A Tangential Entry and Single-Stage Oil-Water Cyclone Separator Realizing Two Separations

Abstract

A tangential inlet and single stage oil-water cyclone separator for double separation. It is characterized in that: an oil phase curved surface coalescing plate is fixed inside the tangential inlet main body, the oil phase curved surface coalescing plate is in the shape of a wavy line, and the oil phase curved surface coalescing plate is placed in the center of the tangential inlet main body , there are three deflectors fixed on the end of the plate away from the tangential inlet liquid; above the coalescing plate on the curved surface of the oil phase, a primary separation pipe is arranged, and several manifolds are connected to the pipes. The openings are respectively located at the center of the area divided by each curved surface on the oil phase curved surface coalescing plate; the single-stage oil-water cyclone separator with the tangential inlet needs to be connected to the tangential inlet and the cyclone The outer walls of the upper part of the chamber are connected tangentially and connected, and the primary separation pipe is connected with the guide pipe and then connected to the overflow pipe. This scheme enables the single-stage oil-water separation cyclone device to have the function of two separations, the equipment occupies a small space, the operation and maintenance are convenient, and the separation effect is good.

Description

technical field [0001] The invention relates to a single-stage cyclone separation device which can be applied in the fields of petroleum, chemical industry, environmental protection and the like, and can perform coalescence and separation of small-diameter oil droplets twice. Background technique [0002] At present, cyclones are more and more widely used in petroleum, chemical and environmental protection industries. However, as oilfield development enters the middle and late stages, the oil-water density difference between heavy oil and polymer-containing production fluid is small, and the viscosity of oil-water emulsion is high. The separation efficiency of the traditional single-stage cyclone separator is low, and the oil-water cannot be fully separated. And other issues. In response to this problem, at present, people have designed a two-stage series cyclone separation device and a separation system that combines cyclones with settling tanks and other equipment. They m...

[0003] Cyclone separation devices have been used in related industries in my country. People improve the overall separation effect of cyclone devices by changing the structure of the cyclone device or adding secondary separation parts. The invention patents involved, such as ZL 201610326039.1, ZL 201310746224.2, CN 201710226452.5, ZL 201320185718.3, ZL201110252013.4, ZL 201220253954.X, CN201310746224.2, CN201610902326.2, etc. In addition to occupying much more space than a single-level device, the maintenance of the above inventions is far more cumbersome and complicated in structure. Cyclone, especially for offshore platforms with limited space, the limitations of these devices are more prominent
