Splitting type three-stage oil and gas separating device of gas compressor

Abstract

The invention discloses a splitting type three-stage oil and gas separating device of a gas compressor, and belongs to the technical field of oil and gas separating. The splitting type three-stage oil and gas separating device comprises a first oil and gas bucket, a second oil and gas bucket and a flow mixing assembly, wherein a gas outlet of the first oil and gas bucket and a gas inlet of the second oil and gas bucket are communicated by an oil and gas pipeline; the first oil and gas bucket comprises a first cylinder, a first gas inlet, a first gas inlet protecting plate and a first oil return pipe; the second oil and gas bucket comprises a second cylinder, an oil separating core, a second gas inlet protecting plate and a second oil return pipe; the flow mixing assembly is connected with the first oil return pipe and the second oil return pipe respectively, and is used for adjusting the flow rate of the second oil return pipe. The splitting type three-stage oil and gas separating device has the advantages that the three-stage separating of mixing gas is realized by the first oil and gas bucket and the second oil and gas bucket, the first oil and gas bucket is used as an oil storage part, and the second oil and gas bucket is used as a separating part of the oil separating core, and is also used as a buffer gas tank, so that the filtering accuracy and operational stability of the gas compressor are further improved; the size is smaller, the layout of the gas compressor is easy, and the installation and maintenance are more convenient and rapid.

Description

technical field [0001] The invention relates to an oil-gas separator, more specifically, to an air compressor split-type three-stage oil-gas separator. Background technique [0002] The air compressor is mainly composed of a host, a motor, an oil-gas separation system, a cooling system, a control system, and a main frame. After the air passes through the intake filter to filter out dust or impurities in the atmosphere, it enters the compressor host through the intake control valve. , mixed with the sprayed cooling lubricating oil during the compression process, and the compressed mixed gas is discharged from the compression chamber into the oil-gas separator. At this time, the compressed and discharged oil-containing gas passes through collision, interception, and gravity, and most of the oil The medium is separated, and then enters the oil and gas fine separator for secondary separation, so that the oil content of the compressed air is further reduced. When the air is compr...

AI Technical Summary

Problems solved by technology

[0005] (1) The oil-gas separator still adopts an integrated structure, and the manufacturing of the cyclone separation cylinder and the filter element separation cylinder is difficult, and the structural design has great limitations, and it is not conducive to the shape and layout of the air compressor, so it is difficult to really popularize and use;

[0006] (2) Due to the integrated structure design, the filter element separation cylinder cannot use the cyclone method to enter the air, and can only achieve two-stage oil-gas separation, and the oil-gas separation efficiency is low;

[0007] (3) Due to the integrated structure design, the layout of the mixed gas inlet and the oil return port is limited, and both the cyclone separation cylinder and the filter element type separation cylinder adopt upper air intake, which increases the load on the filter element; and, the cyclone separation cylinder and the filter element type separation The oil return port of the barrel is directly connected to the lubrication system of the air compressor, which is not conducive to the rapid discharge of residual oil during the test run, thereby affecting the separation performance of the oil separation core, which is also a common defect of the existing air compressor oil-gas separator; and the oil return The outlet is set at the lowest position, and the sewage outlet cannot be effectively installed, resulting in more impurities in the lubricating oil, which affects the service life of the air compressor
