Description

Technical Field

[0001] The utility model relates to a device, in particular to an oil-gas separation device, which separates and recovers the oil and gas mixture existing in the operation of a compressor, and belongs to the field where oil and gas separation is required during the operation of the device. Background Art

[0002] As a device that effectively separates oil and gas in a mixed fluid, the oil-gas separator is widely used in daily applications. As the application scenarios change, designers can realize the application of various scenarios by continuously optimizing the design of the oil-gas separator. During the operation of the circulating gas compressor, due to differences in design and operation, the lubricating oil carried in the gas enters and diffuses in the atmosphere, causing atmospheric pollution. The separation of oil and gas can not only improve the on-site environment, but also achieve the purpose of energy conservation and consumption reduction. The working principle of the oil-gas separator is mainly based on physical separation methods, including gravity separation, centrifugal separation, etc. When the oil-gas mixture enters the separator, it will go through a series of processing processes. For example, after being filtered through a wire mesh, the oil and gas will slide down the pipe wall and undergo multiple separations of the gas-liquid phase, ultimately achieving effective separation of oil and gas.

[0003] Our company's reciprocating circulating gas compressor is the main equipment for compressing and increasing the pressure of synthetic gas. The equipment cylinder structure adopts a balanced double-row structure, with a guide crosshead body at the tail end. Its function is to ensure the balance of the piston during operation, reduce energy consumption, and reduce the wear of the piston ring. During use, the crosshead body of the balancing section needs to be fully lubricated with lubricating oil to ensure that the Babbitt alloy is not easy to wear. Such a design is very likely to cause high-pressure gas to carry lubricating oil into the oil tank when the piston rod wears and the sealing packing fails. The gas carries the lubricating oil into the oil tank, and the gas diffuses from the oil tank into the atmosphere and cannot be recovered, causing pollution to the on-site atmospheric environment.

[0004] This transformation is to simulate the working principle of the oil-gas separator, based on the principles of gravity separation and cyclone separation, and through the application of actual scenarios, independently design the oil-gas separation device to realize the separation and recovery of lubricating oil in the gas. By separating the concentrated gas and removing small oil droplets, the effective separation of oil and gas is finally achieved.

[0005] Through the transformation, not only the harmful gases diffused in the atmosphere were recovered, but also the lubricating oil was saved and recycled, solving the environmental problem while achieving the goal of energy saving and consumption reduction. Utility Model Content

[0006] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide an oil-gas separation device with a reasonable structural design, which improves separation efficiency and improves the on-site environment and achieves energy conservation and consumption reduction through recycling.

[0007] The technical solution adopted by the utility model to solve the above-mentioned problem is: the oil-gas separation device includes high-pressure gas, a gas outlet, an oil drain port, an oil tank and a recovery system, and is characterized in that it also includes an oil-gas separator, a wire mesh filter layer and a swirl plate distributor. The high-pressure gas is provided with lubricating oil. After the high-pressure gas enters the oil-gas separator, the high-pressure gas rises and is blocked by the wire mesh filter layer. The isolated liquid enters the oil drain port at the bottom and enters the oil tank by gravity. After the gas passes through the wire mesh filter layer and enters the swirl plate distributor to separate a small amount of liquid again, it enters the recovery system through the gas outlet for reuse.

[0008] Preferably, the swirl plate distributor of the present invention is located above the wire mesh filter layer, and the wire mesh filter layer and the swirl plate distributor are both arranged in the oil-gas separator.

[0009] Preferably, the wire mesh filter layer of the present invention is three-layered, and the three wire mesh filter layers are arranged at intervals of upper, middle and lower.

[0010] Preferably, the swirl plate distributor of the present invention is made of Q235B material, and is provided with 18 blades evenly distributed in an outward rotation direction, with a blade inclination angle of 25°, and 12 φ16 overflow ports are provided on the outer ring plate of the swirl plate distributor.

[0011] Preferably, the wire mesh filter layer of the present invention is formed by rolling 4*4 stainless steel flat iron and laying 200 mesh stainless steel wire mesh. The height of each layer is 4mm, the interval between layers is 2mm, and a total of three layers are set in the oil-gas separator.

[0012] Compared with the existing technology, the utility model has the following advantages and effects: the overall structural design is reasonable, and the oil removal and separation process is optimized by optimizing the swirl plate distributor and the advanced wire mesh filter layer, and finally the effective separation of oil and gas is achieved. Through effective separation, the lubricating oil carried by the gas enters the oil tank again and is recycled, thereby improving the separation efficiency and improving the on-site environment. The purpose of energy saving and consumption reduction is achieved through recycling, and the use requirements are met. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In this embodiment, the compressor 8 elevates low-pressure gas to high-pressure gas 1, and the high-pressure gas 1 carries lubricating oil into the oil-gas separator 6. Due to the principle of dead weight, while the gas and oil go upward, the liquid is blocked by the wire mesh filter layer 4, and the small oil droplets in the gas are separated. The gas is separated by the wire mesh filter layer 4 and the swirl plate distributor 5, and then the oil and gas are discharged through the gas outlet 2 to the oil-gas separation device, thereby finally realizing the effective separation of oil and gas. Through effective separation, the lubricating oil carried by the gas enters the oil tank 7 again and is recycled, thereby improving the on-site environment and achieving the purpose of energy saving and consumption reduction through recycling.
