Description

Technical Field

[0002] The oil-gas separator body is a device that separates the crude oil and associated natural gas produced by the oil well. It is widely used in solid-liquid, gas-solid, and gas-liquid separation and purification in the fields of petroleum, chemical industry, metallurgy, aviation, electronics, electricity, pharmaceuticals, environmental protection, atomic energy, nuclear industry, natural gas, refractory materials, fire-fighting equipment, etc. The oil-gas separator body is placed between the submersible centrifugal pump and the protector.

[0003] For example, an oil-gas separation filter element assembly with the authorization announcement number "CN215692609U" is provided with a limit slot and a limit plug plate. When the sliding rod is pulled to shrink the fixed block into the movable slot, the limit plug plate is first taken out to make the sliding rod located at the end of the sliding port away from the filter cartridge. Then the limit plug plate is inserted into the limit slot to limit the sliding rod. There is no need for the staff to pull multiple sliding rods at the same time, which further facilitates the installation and removal of the filter cartridge. However, when the oil-gas mixture enters the oil-gas separator body, the oil-gas mixture contains a large number of impurities, which causes the separated oil to be mixed with the impurities. The operator needs to perform secondary filtration on the separated oil, which consumes a lot of physical strength of the operator, thereby increasing the manual labor. At the same time, the oil-gas separation filter element assembly contains many types of oil in the separated oil, which needs to be classified by the operator after discharge, and then classified and collected.

[0025] Refer to the attached Figure 3

[0026] The auxiliary separation mechanism 7 includes a shell 701, the left end of which is fixedly connected to the oil-gas separator body 1, the inner wall of the shell 701 is slidably connected to the pull rod 702, the pull rod 702 is rotatably connected to the shell 701 through a pin, the upper end of the inner wall of the pull rod 702 is slidably connected to the cylinder 703, the rear end of the cylinder 703 is fixedly connected to a cross bar 704, the outer wall of the cross bar 704 is slidably connected to the fixed block 707 and the shell 701, and the outer wall of the cross bar 704 is sleeved with a spring 70 6.

The lower end of vertical rod 705 fits with cross bar 704. Pull the pull rod 702, the pull rod 702 swings and drives the cylinder 703 to slide along the slide groove processed on the pull rod 702, thereby driving the cross bar 704 to move and compressing the spring 706 at the same time.

[0027] Working principle:

[0028] When using oil-gas separation filter element assembly to separate oil and gas:

[0029] Filter installation process:

[0030] The operator first inserts the filter 6 along the groove processed on the intake pipe 4, and then aligns the right end of the sleeve 301 with the center of the left end of the intake pipe 304. At this time, the first flange 304 and the second flange 305 are both in contact. The operator passes the bolt 9 through the through holes processed in the first flange 304 and the second flange 305, and then rotates the nut 10 to make the first flange 304 and the second flange 305 abut against each other. At the same time, the right end of the boss 303 abuts against the filter 306, thereby completing the installation of the filter 306. The filter 306 can filter impurities in the oil-gas mixture, so that the separated oil does not need to be filtered again and can be used directly.

[0031] Adsorbent plate installation process:

[0032] The operator first pulls the upper pull rod 702 to the left, and the pull rod 702 swings to drive the cylinder 703 to slide along the slide groove processed on the pull rod 702, thereby driving the cross bar 704 to move to the right, and at the same time compressing the spring 706. When the slide groove processed on the cross bar 704 moves to just below the vertical rod 705, the lower end of the vertical rod 705 enters the slide groove processed on the cross bar 704. At this time, the cross bar 704 moves out of the inner wall of the oil-gas separator body 1, loosens the pull rod 702, and then the operator moves the adsorbent plate 2 along the oil-gas separator body 1. The adsorbent plate 2 is inserted into the slide groove processed on the top, and then the operator pulls up the vertical rod 705, the spring 706 resets, and drives the cross bar 704 to move to the left. When the left end of the cross bar 704 is in contact with the inner wall of the groove processed on the adsorbent plate 2, the vertical rod 705 is released to complete the installation of the adsorbent plate 2. The above operation is repeated to install the two adsorbent plates 2, so that when the adsorbent plate 2 comes into contact with the oil-gas mixture, the oil and gas separation is more thorough, and there is no need for secondary separation, thereby improving work efficiency.

[0033] Oil and gas separation process:

[0034] The sleeve 301, the exhaust pipe 5 and the oil drain pipe 8 are connected with the corresponding pipelines. The oil-gas mixture enters the intake pipe 4 through the sleeve 301. The sealing gasket 302 can prevent gas leakage and oil leakage. The oil-gas mixture enters the oil-gas separator body 1 through the intake pipe 4 and falls on the adsorbent plate 2. During the falling process of the oil-gas mixture, the gas rises, is filtered by the filter cartridge 6, and is discharged from the exhaust pipe 5. The falling oil passes through two adsorbent plates 2. The adsorbent plates 2 contain adsorbent. For oil mixtures that are not easy to separate by physical methods, the use of adsorbents can be considered. The adsorbent can adsorb one oil but not another oil. To achieve separation, the choice of adsorbent can be selected according to actual needs to meet work requirements. The two adsorbent plates 2 can absorb one type of oil and not absorb the other type of oil. The two types of oil not absorbed by the upper adsorbent plate 2 enter the lower adsorbent plate 2, and the oil not absorbed on the lower adsorbent plate 2 is discharged from the oil drain pipe 8. Then, the pull rod 702 is pulled to the left to make the cross bar 704 slide out of the grooves processed on the two adsorbent plates 2. The two adsorbent plates 2 are taken out, and the oil adsorbed in the adsorbent plates 2 can be squeezed out and collected, so that the oil after oil and gas separation can be classified and collected through the two adsorbent plates 2.
