Abstract

The invention relates to a precise oil-gas separation device and application of the precise oil-gas separation device in a screw-type compressor. The precise oil-gas separation device comprises an upper cover, a barrel body and a filtering core, wherein the upper cover is provided with an air inlet and an air inlet channel which are isolated from each other as well as an air outlet and an air outlet channel which are isolated from each other; the filtering core is hollowly tubular; a condensation fiber net is arranged on the inner wall / outer wall of the hollowly tubular filtering core; a foldable type filtering layer is clamped between the inner wall and the outer wall of the hollowly tubular filtering core; the upper cover is connected with the barrel body through threads; the filtering core is positioned between the upper cover and the barrel body; the bottom of the filtering core is positioned on an oil outlet seat at the bottom of the barrel body; a pipe neck of the filtering core is sleeved on a vertical downward section of the air inlet channel of the upper cover. The precise oil-gas separation device has the advantages that (1) the oil separation rate of the precise oil-gas separation device can reach 99.74% to 99.99%, so that the oil separation efficiency is high and the investment cost of user equipment is lowered; (2) the oil content of compressed air discharged from the screw-type compressor on which the precise oil-gas separation device is mounted is commonly decreased from 3PPM / M<3> to a range within 0.001PPM / M<3> to 0.002PPM / M<3>. Thus, the screw-type compressor can be used for replacing an oilless compressor or is directly used as a low-pressure compressor.

Description

[0001] Technical field: [0002] The invention relates to a screw compressor, in particular to a precision oil-gas separation device and its application on the screw compressor. Background technique: [0003] The oil-air separator is an auxiliary device in the compressed air system. The air compressor needs to use liquid oil to lubricate the kinematic pair during operation to reduce friction and wear of the kinematic pair. At the same time, under the influence of the high temperature generated by the compressor, the lubricating oil is often mixed with high-pressure air in the form of mist and discharged through the exhaust port of the compressor. In the prior art, the mixed oil and gas are usually separated into gas and oil through a separation tank. However, some industries such as food and pharmaceuticals have high requirements on the cleanliness of compressed air, and existing compressors cannot meet such requirements. Invention content: [0004] The object of the pre...
