Description

Technical Field

[0001] The utility model belongs to the technical field of oil-gas separators, in particular to an oil-gas separator. Background Art

[0002] The core role of air compressors in coal chemical production is mainly reflected in their ability to compress gas volume and improve gas purity, thereby improving coal chemical production efficiency and process quality. In the new era, as coal chemical processes develop towards automation, large-scale and intelligent directions, the application of air compressors also faces special requirements, including the scientific nature of system design and application design, as well as in-depth application results in the coal chemical process system. Air compressors usually need to use oil-gas separators to filter the lubricating oil in the gas.

[0003] The existing oil-gas separator usually only has one layer of filter mesh inside to filter the gas, so that the lubricating oil in the gas is filtered and discharged. This method will result in poor filtering effect, resulting in the discharged gas still containing a large amount of lubricating oil, which will affect the use of the compressed gas and make it difficult to meet the requirements for air quality. Therefore, we propose an oil-gas separator. Utility Model Content

[0004] The utility model aims to provide an oil-gas separator, which provides a filter assembly, specifically, the compressed air will first enter the interior of the second filter cartridge, and the second filter cartridge will filter the compressed air for the first time, and the filtered air will be discharged from the second filter cartridge and enter the first filter cartridge, and then the air will be filtered for the second time through the first filter cartridge. The two consecutive filtrations can improve the filtering effect of the air, so that the lubricating oil in the air can be discharged more efficiently, and the quality of the air is improved.
