[0002] In the production of chemical production equipment, reciprocating compressors are the heart of chemical production and play a very important role. The bearings, cylinders, fillers and other parts of the reciprocating compressor are usually powered by circulating oil provided by oil injectors, which provide continuous forced oil supply to the lubricating parts such as bearings, cylinders, fillers, etc., to cool the parts and reduce friction. After the lubricating oil passes through the various levels of lubricating parts of the compressor as a lubricant, part of the lubricating oil is naturally lost in the bearings and cylinders and falls back to the lubricating oil pool for recycling. The other part of the waste oil and waste water generated after lubrication passes through the cylinder and is collected in a vent main pipe through various levels of circuits. The vent main pipe is then led to the high point of the plant frame for direct atmospheric venting.

[0003] When a reciprocating compressor is started or stopped or the vent pipe is opened in an emergency, the oil and water in the compressor body will be carried into the atmosphere along with the vented air. The waste oil and water particles will gush in the air and then fall back onto the roof, equipment and ground, which will cause serious air and ground pollution. At the same time, there is loud noise during venting, and when the venting flow rate is fast and the impact force is large, static sparks may be generated, causing unsafe factors such as ignition of flammable objects.
