A cyclone separation device with adjustable flow direction and multiphase products

Abstract

Disclosed is a cyclone separation device with adjustable flow direction and multiphase products. The cyclone separation device includes a cyclone device overflow pipe, a cyclone upper casing, a cyclone lower casing, a switch lever sleeve, a switch lever, a rod-shaped valve, a spring and a guide vane; the cyclone separation device The separation simulation can be switched through the pushable structure, and the direction of the overflow outlet can be switched to realize two-phase or three-phase separation. This kind of adjustable cyclone separation device is designed for the frequent need to replace the outlet pipeline in the oil field and the production fluid composition is complex, the gas content is unknown, etc. It has the advantages of simple mode switching, fast separation speed, simple structure and easy processing, and can It realizes the characteristics of continuous separation, enhances the feasibility and applicability of the oil-water separation device, and can be used in the petroleum industry, environmental protection industry and other fields.

Description

technical field [0001] The invention relates to a cyclone separation device. Background technique [0002] Cyclone separation is a rapid separation method for two-phase or multi-phase immiscible media. The separation principle of the cyclone separation device is to use the density difference between the immiscible media to perform centrifugal separation. The cyclone separation device has small equipment volume, With the advantages of rapid separation, it is widely used in the separation of immiscible media such as petroleum exploration, chemical industry, food processing, and environmental protection. However, due to the on-site working conditions and the complex composition of the produced fluid, higher requirements are placed on the field applicability of the separation device. When the produced fluid does not contain gas or has a low gas content, it is not necessary to separate the gas phase separately; but When the gas content of the produced liquid is high, it is neces...

AI Technical Summary

Problems solved by technology

However, due to the on-site working conditions and the complex composition of the produced fluid, higher requirements are placed on the field applicability of the separation device. When the produced fluid does not contain gas or has a low gas content, it is not necessary to separate the gas phase separately; but When the gas content of the produced liquid is high, it is necessary to separate the three phases of oil, gas and water

Because the existence of a large amount of gas phase will increase the degree of mixing and turbulence between phases, resulting in unstable separation, and the existence of gas phase will also occupy the space of the overflow oil outlet, affecting the oil-water separation effect of the cyclone device; Other components on the process column connected to the cyclone separator will affect each other, and eventually affect each other, further deteriorating the separation effect

In the prior art, there is no cyclone separation device that can flexibly switch working modes according to different working conditions and production fluid requirements to enhance the applicability of separation equipment to changing working conditions
