Description

Technical Field

[0001] This utility model relates to the field of oil and gas separation technology, and specifically to an oil and gas separation and recovery device. Background Technology

[0002] Oil and gas separation and recovery refers to the technical process of separating oil and gas mixtures volatilized during industrial production, storage and transportation through physical, chemical or physicochemical means, so as to realize the recovery and reuse of oil and gas or achieve emission standards. For example, the patent document with announcement number CN220802310U discloses an oil and gas separation and recovery device. The device has a motor in the mist receiving plate, and the motor drives the cleaning scraper and the discharge scraper to move in a circular motion synchronously. The cleaning scraper can scrape off the mist adhering to the wire mesh demister, ensuring that the mesh of the wire mesh demister is unobstructed and realizing the self-cleaning function, which is conducive to improving the gas demisting efficiency. The discharge scraper can scrape the mist collected in the mist receiving plate to the mist discharge port for discharge. During operation, the mist receiving plate continuously discharges, which can ensure the continuous operation of the mist receiving plate.

[0003] However, in existing devices, the scraper is positioned on the lower surface of the demister. During rotation, the scraper compresses the mist on the demister surface, causing the mist to not only fail to be effectively scraped off but also to penetrate into the demister mesh, preventing the demister from performing oil-gas separation.

A scraper 19 is fixedly installed at the lower side of the air outlet plate 10. Both the air outlet pipe 12 and the vertical tube 9 are made of rigid plastic pipes. A sealed bearing is used for rotational engagement between the air outlet pipe 12 and the vertical tube 9. A drive motor 13 is fixedly installed on the top of the cover plate 3.

The sector gear 17 is configured to cooperate with the transmission gear 18. The transmission gear 18 is fixedly sleeved with the vertical tube 9.

[0020] In order to effectively filter the gas drawn by the air pump and minimize the entry of impurities in the gas into the separator and contamination of the demister, such as... Figure 3As shown, the air pump 11 has a filter tube 20 screwed onto its air inlet end, and an air inlet filter screen 21 is fixedly installed at the end of the filter tube 20.

[0021] Working principle: The oil-gas mixture to be separated is injected into the oil box 1 through the filling pipe 8. Some liquid oil is retained in the oil box 1, while the oil-gas mixture enters the upper area of ​​the separation cylinder 2 through multiple radially evenly distributed air guide pipes 7, realizing the initial separation of oil and gas. The oil-gas mixture entering the separator 2 flows upward and first passes through the demister 6. The demister 6 intercepts the mist in the oil-gas mixture. The intercepted mist falls to the mist receiving plate 4 under the action of gravity, and then enters the waste discharge pipe 23 through the mist discharge hole 5 on the mist receiving plate 4. Finally, it is discharged from the separator 2 through the waste discharge pipe 23, completing the collection and discharge of mist. To prevent mist from clogging the demister 6 mesh, the air pump 11 and drive motor 13 are started. The air pump 11 draws air through the filter pipe 20 at the air inlet, and the air filter 21 filters impurities in the air. The filtered air is then delivered to the vertical pipe 9 through the air outlet pipe 12. At the same time, the drive motor 13 drives the drive bevel gear 14 on the output shaft to rotate. The drive bevel gear 14 meshes with the transmission bevel gear 16 on the vertical rod 15, causing the vertical rod 15 to rotate. The sector gear 17 on the vertical rod 15 rotates along with it. The sector gear 17 engages with the transmission gear 18, driving the transmission gear 18. The spherical gear 18 and the vertical tube 9 fixedly connected to it rotate. When the vertical tube 9 rotates, the air outlet plate 10 at its lower end rotates synchronously. The bottom of the air outlet plate 10 is shell-extracted and connected to the vertical tube 9. After the air in the vertical tube 9 enters the air outlet plate 10, it blows air longitudinally from the bottom to the mesh of the demister 6. The scraper 19 at the lower side of the air outlet plate 10 slightly scrapes the surface of the demister 6, so that the mist is away from the demister 6, ensuring that the demister 6 is unobstructed. The air outlet pipe 12 and the vertical tube 9 are rotated with sealed bearings and are both rigid plastic pipes, which ensures stable air delivery and does not affect the rotation of the vertical tube 9. The defoamed gas is discharged from the separator cylinder 2 through the gas outlet pipe 24 on the cover plate 3. The discharged gas can be further processed or recycled as needed. The cover plate 3 and the separator cylinder 2 are fixed together by multiple mounting bolts 22, which facilitates the subsequent opening of the cover plate 3 to maintain the internal components of the separator cylinder 2.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
