Description

Technical Field

[0001] The utility model relates to the technical field of oil-gas separation, in particular to a high-efficiency oil-gas separation mechanism for an air compressor. Background Art

[0002] The oil-gas separator is a device that separates the crude oil and associated natural gas produced by the oil well. The oil-gas separator is placed between the submersible centrifugal pump and the protector to separate the free gas in the well fluid from the well fluid. The liquid is sent to the submersible centrifugal pump, and the gas is released into the annular space between the oil pipe and the casing.

[0003] There is a high-efficiency air compressor oil-gas separator (its authorization announcement number is: CN219595931U), which is equipped with a filter barrel to filter impurities in natural gas. When the drive shaft rotates, the filter barrel can be rotated under the meshing transmission action of the drive gear and the outer gear ring. The scraper can be used to scrape off impurities attached to the filter barrel, thereby ensuring that the filtration flow rate of the filter barrel will not be reduced.

[0004] However, this type of air compressor oil-gas separator has some shortcomings during actual use: the impurities attached to the surface of the rotating filter barrel are scraped off by the scraper, and the scraped impurities will directly fall down into the crude oil at the bottom of the oil-gas separation tank, affecting the quality of the crude oil; therefore, the present utility model is proposed to solve the above problems.
