Technical Field

The invention relates to the technical field of air compressors and peripheral supporting facilities thereof, in particular to an oil-gas separator for a medium-pressure compressor.

Background

In the oil injection displacement type air compressor, when gas is compressed, a large amount of lubricating oil is injected into a compression cavity to form an oil-gas mixture with the gas, and the oil-gas mixture is discharged into an oil-gas separator from an air inlet at the end of compression. The oil-gas mixture is roughly separated in the separator, and then is finely separated by the oil separator and discharged out of the unit. The separated lubricating oil is finally sprayed into the compression cavity of the compressor through the oil pipe, so that the recycling of the lubricating oil is realized. The oil-gas separator is one of the main devices in an oil injection displacement type compressor unit system, and the structure of the oil-gas separator not only influences the quality of air supply of the unit and the convenience of maintenance, but also influences the overall layout of the unit.

In the prior art, compressed gas is discharged after being separated by an oil-gas separator and then is separated by an oil mist fine separator, but the common oil mist fine separator has low pressure resistance and high temperature resistance and is generally only applied to a normal-pressure compressor, and a compressor above the medium pressure needs to be changed into a special oil mist fine separator with high cost.

The lubricating oil separated by the oil-gas separator is filtered and then supplied to a main machine of the compressor, and a lubricating oil filter is arranged between the oil-gas separator and the main machine, but the common lubricating oil filter has low pressure resistance and high temperature resistance and is generally only applied to a normal-pressure compressor, and a compressor above the medium pressure needs to be changed into a special lubricating oil filter with high cost.

In the existing compressor system, an independent oil mist fine separator and an independent lubricating oil filter are arranged. The inside pressure of independent oil mist fine separator and lubricating oil filter is system pressure, and external pressure is atmospheric pressure, and along with system pressure improves, the pressure differential that oil mist fine separator and lubricating oil filter bore is just bigger, and current oil mist fine separator and lubricating oil filter can not be able to bear the pressure more than the middling pressure.

Therefore, how to change the current situation that the pressure difference between the oil mist separator and the oil filter which are independently arranged in the compressor system is large in the prior art becomes a problem to be solved by those skilled in the art.
