Cyclone oil-gas separator and separation method

Abstract

The invention belongs to the field of oil and gas treatment equipment, and relates to a cyclone oil-gas separator and a separation method. The oleophylic and oleophobic textures are formed in the inner wall surface of a cylindrical cyclone outer cylinder of the separator, the oleophylic and oleophobic texture texture is formed along the rotational flow direction of an oil-gas mixture, and starts from the inlet of the oil-gas mixture and is rotated downwards to the bottom of the cylindrical cyclone outer cylinder; and the second oleophylic and oleophobic texture is vertically arranged in a downward mode and starts at the top of the cylindrical cyclone outer cylinder and terminates at the first oleophylic and oleophobic texture; the first oleophylic and oleophobic texture and the second oleophylic and oleophobic texture both comprise a plurality of oleophylic textures and oleophobic textures which are arranged at intervals. According to the cyclone oil-gas separator, the oleophylic and oleophobic textures are arranged on the inner wall surface of the outer cylinder, so that the technical problem that the separation efficiency is influenced by redrawing oil film into an air phase flowfield due to the fact that a piece of oil film on the inner wall surface of an existing cyclone oil-gas separator is scratched by a rotational flow field to splash the secondary little small oil drops is effectively solved, and the efficiency of the cyclone separator is improved.

Description

technical field [0001] The invention belongs to the field of oil and gas processing equipment, and relates to a cyclone type oil and gas separator used for oil and gas separation in an oil injection compressor and a separation method. Background technique [0002] Oil and gas separation efficiency is one of the key indicators for evaluating the performance of oil-injected compressor systems. For oil-injected compressors, cyclone separators are generally used as their rough separation equipment. Its structure mainly includes mixed gas inlet pipes, cyclone outer cylinders Body, cyclone inner cylinder, oil discharge pipe. The oil-gas mixture enters the inside of the separator cylinder tangentially from the inlet pipe, and rotates in the annular flow field formed between the inner cylinder and the outer cylinder. The oil droplets move radially outward due to the greater centrifugal force. When they hit When it reaches the inner wall of the outer cylinder, it will adhere to the ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problems such as splashing oil film on the wall surface of the traditional cyclone oil-gas separator, the present invention provides a cyclone oil-gas separator and a separation method, which is characterized in that oleophilic and oleophobic striped textures are formed on the inner wall of the cyclone outer cylinder to Disintegrate the oil film formed on the inner wall of the separator, rectify the oil film and strengthen the dredging
