Description

Technical Field

[0001] This invention belongs to the field of oil and gas recovery, specifically an oil and gas recovery absorption tower. Background Technology

[0002] An oil and gas recovery absorption tower is a vertical chemical equipment used in oil and gas recovery and treatment systems to achieve gas-liquid mass transfer. It mainly works by having a mixture of oil and gas contact a liquid absorbent in a counter-current or co-current manner. Utilizing the principle of "like dissolves like," the oil and gas components in the mixture are selectively dissolved or captured by the absorbent, thereby achieving the separation of oil and gas from non-condensable gases such as air.

[0003] Patent CN215352794U discloses an oil and gas recovery absorption tower, relating to the field of oil and gas recovery. The tower includes an absorption tower body, an oil inlet fixedly connected to the top left side of the absorption tower body, guide plates symmetrically fixedly connected to the left and right sides of the top of the absorption tower body's inner cavity, an exhaust chamber fixedly connected to the top of the absorption tower body, a gas-liquid separator fixedly connected to the bottom of the exhaust chamber's inner cavity, a cover fixedly connected to the top of the exhaust chamber, an exhaust pipe fixedly connected to the top of the cover, a partition plate at the bottom of the guide plates, and a recovery chamber in the middle of the absorption tower body's inner cavity. This oil and gas recovery absorption tower, through the cooperation of the oil inlet, guide plates, spray components, fixed rods, and spray heads, can achieve uniform spraying of the oil injected through the oil inlet into the recovery chamber, improving the uniformity of oil spraying and oil and gas distribution, and achieving a high oil and gas recovery rate.

[0004] However, the above technical solutions still have the following shortcomings in practical applications:

[0005] The oil and gas to be treated are introduced into the absorption tower and, after preliminary filtration by the filter plates, enter the recovery chamber. At the same time, lean oil is conveyed to the spray system for spraying to contact and absorb the oil and gas.

[0006] The drawback of this solution is that, as the operating time increases, impurities will inevitably accumulate on the surface of the filter plate. Over time, these accumulated impurities will clog the filter holes, hindering the smooth passage of oil and gas and reducing the processing efficiency.

[0007] Current methods for cleaning filter plates typically require removing them from the tower body. This method is not only time-consuming and labor-intensive, but more importantly, the disassembly process inevitably leads to prolonged equipment downtime, severely impacting production continuity. Summary of the Invention

[0008] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, the present invention proposes an oil and gas recovery absorption tower.

[0009] The technical solution adopted by the present invention to solve its technical problem is: an oil and gas recovery absorption tower, including an absorption tower body and a lean oil tank, wherein the lean oil tank is fixedly connected to one side of the outer wall of the absorption tower body, and multiple branch pipes are fixedly connected to the top of the inner wall of the absorption tower body. Multiple spray heads are provided at the bottom of the branch pipes. The lean oil tank is filled with lean oil and is equipped with an oil pump for extracting lean oil. The oil pump outlet is connected to a connecting pipe, which is connected to the ends of the multiple branch pipes. The invention includes a switching self-cleaning filter assembly for filtering impurities in the oil and gas.

[0010] The switching self-cleaning filter assembly includes a filter box fixedly connected to the top of the absorption tower. An air inlet pipe is located at the middle of the upper end of the filter box. The middle of the lower end of the filter box is connected to the inner cavity of the absorption tower via a connecting pipe. Partitions are fixedly connected to both sides of the inner wall of the filter box, dividing the interior of the filter box into two cleaning chambers and one filtration chamber. Filter plates are slidably inserted into the middle of the two partitions along the horizontal direction. Multiple filter holes are provided on the filter plates. Guide rods are slidably inserted vertically on both sides of the bottom of the filter box. A lifting plate is fixedly connected to the upper end of the guide rod. Multiple sub-plates are distributed and fixedly connected to the upper surface of the lifting plate along the horizontal direction. A row of pins matching the filter hole specifications is fixedly connected to the upper surface of each sub-plate. Guide rods are slidably inserted horizontally on both sides of the filter box. A scraper is fixedly connected to one end of the guide rod located in the inner cavity of the filter box, with the lower surface of the scraper adhering to the upper surface of the filter plate.

[0011] Preferably, an exhaust pipe is provided on one side of the absorption tower body, and an oil drain pipe is provided at the bottom of the absorption tower body.

[0012] Preferably, a lead screw guide rail module is provided on one side of the outer wall of the filter box, and a slider is fixedly connected to the moving end of the lead screw guide rail module. One end of the slider is fixedly connected to one side of the upper surface of the filter plate.

[0013] Preferably, cylinder three is fixedly connected to both sides of the lower surface of the filter box, and the piston ends of cylinder three on both sides are fixedly connected to one side of the bottom of the two lifting plates respectively.

[0014] Preferably, a cylinder is fixedly connected to both sides of the outer wall of the filter box, and the piston ends of the two cylinders are respectively fixedly connected to one side of the two scrapers.

[0015] Preferably, a conveying pipe is fixedly connected to one end face of the filter box, and a spiral conveying rod is rotatably connected to both ends of the inner cavity of the conveying pipe. The two spiral conveying rods are provided with spiral blades in different directions. A discharge pipe is provided at the center of the bottom of the conveying pipe. Rectangular openings communicating with the inner cavity of the conveying pipe are provided on both sides of the filter box. A collection box aligned with the discharge pipe is provided on one side of the upper surface of the absorption tower. A motor is fixedly connected to both ends of the conveying pipe, and the output ends of the two motors are fixedly connected to the ends of the two spiral conveying rods respectively.

[0016] Preferably, it includes collection auxiliary components;

[0017] The collection auxiliary component includes a rotating shaft rotatably connected to one end of the scraper, with multiple blades fixedly sleeved on the rotating shaft along the transverse direction, and a second cylinder fixedly connected to one side of the upper surface of the scraper, with a pressure plate fixedly connected to the piston end of the second cylinder.

[0018] Preferably, racks are fixedly connected to both sides of the inner wall of the filter box, and a gear that meshes with the racks is fixedly sleeved on one end of the rotating shaft.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The oil and gas recovery absorption tower of this invention, by setting a switching self-cleaning filter assembly, allows the filter plate to intermittently switch between the filtration chamber and the cleaning chamber. This working method cleans the impurities accumulated on the surface of the filter plate and the dirt clogging the walls of the filter pores. Since the equipment does not need to be stopped during cleaning, it effectively ensures the efficient and smooth passage of oil and gas, significantly improves the processing efficiency, and ensures the continuity of production.

[0021] 2. The oil and gas recovery absorption tower of this invention utilizes a collection auxiliary component. When the scraper pushes impurities, the gear rotates under the action of the rack, causing the shaft and multiple blades to rotate synchronously. The impurities pushed by the scraper are cut by the blades, thus dispersing the clumps of impurities. Furthermore, when the scraper moves to the conveying pipe, the impurities on the filter plate surface have been uniformly broken. At this point, the impurities can be compressed by the cylinder driving the pressure plate downward. This further compresses the volume of the impurities, making the impurities entering the conveying pipe not only more compact due to volume compression, facilitating centralized collection, but also uniformly dispersed into fragments due to pre-cutting by the blades. This effectively avoids the risk of blockage of lumpy impurities during subsequent pipeline transportation, ensuring that the impurities can be smoothly pushed to the discharge pipe, achieving stable and efficient collection of impurities.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Please refer to Figures 1-8 The present invention provides a technical solution: an oil and gas recovery absorption tower, including an absorption tower body 2 and a lean oil tank 4. The lean oil tank 4 is fixedly connected to one side of the outer wall of the absorption tower body 2.

[0034] The switching self-cleaning filter assembly includes a filter box 1 fixedly connected to the top of the absorption tower body 2. An air inlet pipe 5 is located at the middle of the upper end of the filter box 1, and the middle of the lower end of the filter box 1 is connected to the inner cavity of the absorption tower body 2 via a connecting pipe 23. Partitions 34 are fixedly connected to both sides of the inner wall of the filter box 1, dividing the interior of the filter box 1 into two cleaning chambers and one filtering chamber. Filter plates 14 are slidably inserted into the middle of the two partitions 34 along the horizontal direction. Multiple filter holes 15 are provided on the filter plates 14. The bottom sides of the filter box 1 are also equipped with... A guide rod 28 is slidably inserted vertically. A lifting plate 21 is fixedly connected to the upper end of the guide rod 28. Multiple partition plates 19 are distributed and fixedly connected to the upper surface of the lifting plate 21 in the horizontal direction.

The lower surface of the scraper 12 is in contact with the upper surface of the filter plate 14.

[0035] In this embodiment, as Figures 2-5 , Figure 8 As shown, an exhaust pipe 3 is provided on one side of the absorption tower body 2, and an oil drain pipe 26 is provided at the bottom of the absorption tower body 2.

[0036] A lead screw guide module 17 is provided on one side of the outer wall of the filter box 1. A slider 16 is fixedly connected to the moving end of the lead screw guide module 17. One end of the slider 16 is fixedly connected to one side of the upper surface of the filter plate 14.

[0037] Cylinder 22 is fixedly connected to both sides of the lower surface of filter box 1. The piston ends of cylinder 22 on both sides are fixedly connected to one side of the bottom of two lifting plates 21 respectively.

[0038] Cylinder 10 is fixedly connected to both sides of the outer wall of filter box 1, and the piston ends of the two cylinders 10 are fixedly connected to one side of the two scrapers 12 respectively.

[0039] A conveying pipe 9 is fixedly connected to one end face of the filter box 1. Both ends of the inner cavity of the conveying pipe 9 are rotatably connected to a spiral conveying rod 27, and the two spiral conveying rods 27 are provided with spiral blades in different directions. A discharge pipe 13 is provided at the center of the bottom of the conveying pipe 9. Both sides of the filter box 1 are provided with rectangular openings that communicate with the inner cavity of the conveying pipe 9. A collection box 7 aligned with the discharge pipe 13 is provided on one side of the upper surface of the absorption tower body 2. Both ends of the conveying pipe 9 are fixedly connected to motors 8, and the output ends of the two motors 8 are fixedly connected to the ends of the two spiral conveying rods 27 respectively.

[0040] Specifically, in the prior art, the oil and gas to be treated are introduced into the absorption tower 2, and after preliminary filtration by the filter plate 14, they enter the recovery chamber. At the same time, lean oil is transported to the spray unit for spraying to contact and absorb the oil and gas.

[0041] The drawback of this solution is that, as the operating time increases, impurities will inevitably accumulate on the surface of the filter plate 14. Over time, these accumulated impurities will block the filter holes 15, hindering the smooth passage of oil and gas and reducing the processing efficiency.

[0042] The existing method for cleaning filter plate 14 usually requires removing it from the tower body. This method is not only time-consuming and labor-intensive, but more importantly, the disassembly process inevitably leads to a long downtime of equipment, which seriously affects the continuity of production.

[0043] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0044] The oil and gas are fed into the filter chamber of the filter box 1 through the air inlet pipe 5, where the filter plate 14 intercepts impurities in the oil and gas. Then, the oil and gas enter the absorption tower body 2 through the connecting pipe 23, and the lean oil is extracted by the oil pump in the lean oil tank 4. The lean oil is sprayed out from multiple spray heads 25 through the connecting pipe 6 and multiple branch pipes 24, and absorbs the oil and gas.

[0045] The purified oil and gas are discharged through exhaust pipe 3, while the oil is discharged through oil drain pipe 26.

[0046] After the filter plate 14 has been used for a period of time, the lead screw guide module 17 is started, and its moving end drives the slider 16 to move laterally, so that the part of the filter plate 14 located in the filter chamber enters the right cleaning chamber, while the part located in the left cleaning chamber enters the filter chamber, thereby realizing the switching of the two sets of filter holes 15. At this time, the filter holes 15 located in the filter chamber can work normally.

[0047] Simultaneously, cylinder 22, located at the bottom of the right-side cleaning chamber, is activated and lifts the lifting plate 21, causing multiple ejector pins 20 to simultaneously penetrate the filter holes 15 until the upper surface of the ejector pins 20 is flush with the upper surface of the filter plate 14. This ejects impurities adhering to the filter holes 15. Subsequently, cylinder 10 on the right side is activated and moves the scraper 12 laterally along the surface of the filter plate 14, scraping off impurities adhering to the surface of the filter plate 14 and pushing the impurities into the inner cavity of the conveying pipe 9. This completes the cleaning of the surface of the filter plate 14 and the impurities adhering to the walls of the filter holes 15.

[0048] When a certain amount of impurities accumulates again on the surface of the filter plate 14 located in the filtration chamber, this portion will move to the left cleaning chamber for cleaning. By repeating the above operation, the filter plate 14 can be cleaned without stopping the machine, thus ensuring the smooth passage of oil and gas, thereby improving processing efficiency and production continuity.

[0049] In addition, since the cleaned-up impurities will enter the conveying pipe 9, the impurities can be gathered in the middle of the conveying pipe 9 by the rotation of the screw conveyor rod 27 driven by the motor 8, and finally fall into the collection box 7 through the discharge pipe 13, so that it is convenient for personnel to collect the impurities.

[0050] In this embodiment, as Figure 6 and Figure 7 As shown, it includes collection auxiliary components;

[0051] The collection auxiliary components include a rotating shaft 31 rotatably connected to one end of the scraper 12, a plurality of blades 32 fixedly mounted on the rotating shaft 31 along the transverse direction, a cylinder 18 fixedly connected to one side of the upper surface of the scraper 12, and a pressure plate 33 fixedly connected to the piston end of the cylinder 18.

[0052] Both sides of the inner wall of the filter box 1 are fixedly connected to racks 29, and one end of the rotating shaft 31 is fixedly fitted with a gear 30 that meshes with the racks 29.

[0053] Specifically, in the above embodiments, although impurities can be collected by pushing them into the conveying pipe 9 through the scraper 12, as impurities accumulate on the surface of the filter plate 14, impurity agglomeration may occur. When the agglomerated impurities move in the conveying pipe 9, they are prone to getting stuck, which prevents them from moving normally to the discharge pipe 13, thus affecting the normal collection of impurities.

[0054] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0055] When the scraper 12 pushes the impurities to move, the gear 30 will rotate under the action of the rack 29, and the shaft 31 and multiple blades 32 will rotate synchronously. The impurities pushed by the scraper 12 will be cut by the blades 32, thereby dispersing the clumped impurities.

[0056] Furthermore, when the scraper 12 moves to the conveying pipe 9, the impurities on the surface of the filter plate 14 have been uniformly broken. At this time, the impurities can be compressed by the cylinder 18 driving the pressure plate 33 to descend. This further compresses the volume of the impurities, making the impurities entering the conveying pipe 9 not only more compact due to the compression, facilitating centralized collection, but also uniformly dispersed into fragments due to the pre-cutting by the blade 32. This effectively avoids the risk of blocky impurities getting stuck during subsequent pipeline transportation, thus ensuring that the impurities can be smoothly pushed to the discharge pipe 13, achieving stable and efficient collection of impurities.

[0057] Working principle: Oil and gas are fed into the filter chamber of filter box 1 through air inlet pipe 5, and filter plate 14 intercepts impurities in the oil and gas. Then, the oil and gas enter the absorption tower body 2 through connecting pipe 23, and then the lean oil is extracted by the oil pump in lean oil tank 4. The lean oil is sprayed out from multiple spray heads 25 through connecting pipe 6 and multiple branch pipes 24, and absorbs the oil and gas.

[0058] The purified oil and gas are discharged through exhaust pipe 3, while the oil is discharged through oil drain pipe 26.

[0059] After the filter plate 14 has been used for a period of time, the lead screw guide module 17 is started, and its moving end drives the slider 16 to move laterally, so that the part of the filter plate 14 located in the filter chamber enters the right cleaning chamber, while the part located in the left cleaning chamber enters the filter chamber, thereby realizing the switching of the two sets of filter holes 15. At this time, the filter holes 15 located in the filter chamber can work normally.

[0060] Simultaneously, cylinder 22, located at the bottom of the right-side cleaning chamber, is activated and lifts the lifting plate 21, causing multiple ejector pins 20 to simultaneously penetrate the filter holes 15 until the upper surface of the ejector pins 20 is flush with the upper surface of the filter plate 14. This ejects impurities adhering to the filter holes 15. Subsequently, cylinder 10 on the right side is activated and moves the scraper 12 laterally along the surface of the filter plate 14, scraping off impurities adhering to the surface of the filter plate 14 and pushing the impurities into the inner cavity of the conveying pipe 9. This completes the cleaning of the surface of the filter plate 14 and the impurities adhering to the walls of the filter holes 15.

[0061] When a certain amount of impurities accumulates again on the surface of the filter plate 14 located in the filtration chamber, this portion will move to the left cleaning chamber for cleaning. By repeating the above operation, the filter plate 14 can be cleaned without stopping the machine, thus ensuring the smooth passage of oil and gas, thereby improving processing efficiency and production continuity.

[0062] In addition, since the cleaned-up impurities will enter the conveying pipe 9, the impurities can be gathered in the middle of the conveying pipe 9 by the rotation of the screw conveyor rod 27 driven by the motor 8, and finally fall into the collection box 7 through the discharge pipe 13, so that it is convenient for personnel to collect the impurities.

[0063] When the scraper 12 pushes the impurities to move, the gear 30 will rotate under the action of the rack 29, and the shaft 31 and multiple blades 32 will rotate synchronously. The impurities pushed by the scraper 12 will be cut by the blades 32, thereby dispersing the clumped impurities.

[0064] Furthermore, when the scraper 12 moves to the conveying pipe 9, the impurities on the surface of the filter plate 14 have been uniformly broken. At this time, the impurities can be compressed by the cylinder 18 driving the pressure plate 33 to descend. This further compresses the volume of the impurities, making the impurities entering the conveying pipe 9 not only more compact due to the compression, facilitating centralized collection, but also uniformly dispersed into fragments due to the pre-cutting by the blade 32. This effectively avoids the risk of blocky impurities getting stuck during subsequent pipeline transportation, thus ensuring that the impurities can be smoothly pushed to the discharge pipe 13, achieving stable and efficient collection of impurities.
