Most air compressors use reciprocating pistons, rotating vanes, or rotating screws. Screw compressors are rotary positive displacement compressors, in which two rotors with helical gears mesh with each other, causing the volume of the two rotors to decrease at the meshing point, thereby compressing and discharging the gas.

[0004] This exhaust device for a screw air compressor discharges waste liquid into a liquid collecting tank, which greatly reduces the waste liquid content in the discharged gas. It not only reduces the failure rate of gas equipment but also reduces air pollution. The operator can clean up the waste liquid in the liquid collecting tank in time by observing the liquid level gauge. However, after the entire device intercepts and filters the liquid impurities and product debris contained in the gas discharged by the device, it is not convenient for the staff to easily remove the impurities intercepted inside the device.

The filter plate inside the mounting frame can intercept and filter a large amount of liquid impurities and product residues in the gas to the surface of the filter plate. The guide plate at the bottom end of the inner wall of the exhaust box can be used to guide the water and oil contained in the gas to the bottom of the drainage pipe. When the water and oil content is too much, because the equipment is in a static state, the water and oil are separated with the cooperation of the oil blocking plate 1 and the oil blocking plate 2, thereby avoiding the air compressor directly discharging the gas and affecting the environment and air around the construction.

[0018] The utility model can provide more detailed filtration by setting the filter plate, effectively remove particulate matter and impurities in the exhaust process, protect downstream equipment from damage, and improve the sealing performance and efficiency of the exhaust system by setting two valves.
