Efficient oil-gas separator for compressors

Abstract

The invention provides an efficient oil-air separator for compressors. The efficient oil-air separator comprises a tank, a bladed cylinder, a filter member, a retaining plate, a return oil pipe and a seal cover in hermetic connection with the tank. The bladed cylinder, the filter member and the return oil pipe are disposed within the tank. The tank is provided with an air inlet; the seal cover is provided with an air outlet. The bladed cylinder is an open hollow cylinder provided with surface blades. The bladed cylinder is slidably connected with the retaining plate. The filter element is disposed within the bladed cylinder. The efficient oil-air separator has the advantages that after high-speed air mixing with lubricating oil flows in, the high-speed air interacts with the bladed cylinder outside the filter element, the flowing speed decreases, and air impact upon the filter element is lower; meanwhile, large particles of the lubricating oil in the air can be attached to the surface of the bladed cylinder, and chances of blockage of the filter element are slimmed.

Description

Technical field [0001] The invention belongs to the field of air compressor accessories, and in particular relates to a high-efficiency oil-gas separator for compressors. Background technique [0002] In an oil-injected air compressor system, the high-temperature and high-pressure gas discharged from the compressor contains a large amount of lubricating oil, which not only causes the loss of lubricating oil, but also reduces the refrigeration efficiency after this air enters the refrigeration system. The prior art oil and gas separators mostly use filter-type filter element separation. The high-speed airflow directly contacts the filter element. Not only is it easy to break the filter element, but the thick oil film is easy to block the filter element, which reduces the service life of the filter element and the replacement cycle is short. Waste of resources and work inconvenience. Summary of the invention [0003] The problem to be solved by the invention is to provide a high-ef...

Problems solved by technology

[0002]In the oil-injected air compressor system, the high-temperature and high-pressure gas discharged from the compressor contains a large amount of lubricating oil, which not only leads to the loss of lubricating oil, but also After the air enters the refrigeration system, it will cause the cooling efficiency to decrease

The oil-gas separator in the prior art mostly adopts the separation method of the filtering filter element. The high-speed air flow directly contacts the filter element, which not only easily damages the filter element, but also easily blocks the filter element due to an over-thick oil film, which reduces the service life of the filter element and shortens the replacement cycle, resulting in Waste of resources and inconvenience
