Description

Technical Field

[0001] This utility model relates to the field of oil and gas recovery technology, specifically to a three-stage oil and gas recovery device based on membrane separation. Background Technology

[0002] The membrane separation three-stage oil and gas recovery equipment utilizes the selective permeation characteristics of polymer membranes to achieve efficient separation of oil and gas from air under pressure differential. The oil and gas mixture is pressurized by the compressor and enters the membrane separator. The polymer membrane has preferential permeability to hydrocarbon molecules (such as gasoline vapor), while air is retained. Hydrocarbon molecules pass through the membrane layer and enter the inner side, forming enriched oil and gas (recovered gas). The pressure drops to near atmospheric pressure, and air and a small amount of unpermeated hydrocarbons are retained, forming lean oil and gas (exhaust gas). The pressure is close to the inlet pressure, and the recovered gas on the permeate side can be further liquefied and returned to the oil depot through condensation.

[0003] In order to improve the efficiency of oil and gas recovery, existing devices use separation membranes to separate oil and gas, which can intercept impurities in the oil and gas, making the separated oil and gas purer. Membrane separation can reduce the need to add absorbents or adsorbents during the oil and gas separation process, and can avoid chemical residues and secondary pollution.

[0004] However, since a certain amount of particulate and colloidal impurities remain in the oil and gas, these impurities will adhere to the separation membrane after the oil and gas are filtered by the separation membrane, which will affect the separation effect of the separation membrane on oil and gas. The separation membrane needs to be replaced by the staff. This not only affects the separation effect of the separation membrane on oil and gas, resulting in a significant decrease in oil and gas permeability, but also affects the service life of the separation membrane. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a three-stage oil and gas recovery device based on membrane separation method, which can solve the existing problems.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A tertiary oil and gas recovery device based on membrane separation includes: a recovery tank with an inlet pipe, a condenser, and a separation membrane body; a scraping assembly mounted on the recovery tank, comprising an explosion-proof motor with a threaded rod at its output end, a scraper with a protective pad and a heating block; and a collection assembly mounted on the recovery tank, comprising an inclined chute, a storage tank, a lead screw, and a baffle.

[0008] Furthermore, the scraping assembly also includes two sets of symmetrically arranged slides inside the recycling bin, with a threaded rod rotatably mounted in the slide, and a slider mounted on the outside of the threaded rod, the slider being movable within the slide.

[0009] Furthermore, the slider and the scraper are fixedly connected, and a storage slot is provided on the top inner side of the recycling bin, which matches the scraper.

[0010] Furthermore, a protective pad is disposed on the side of the scraper close to the separation membrane body, and the protective pad is in contact with the separation membrane body.

[0011] Furthermore, two sets of limiting plates are symmetrically arranged on the side of the scraper away from the storage groove.

[0012] Furthermore, the collection component also includes a through groove at the bottom of the sloping trough, which extends through the recycling bin, and the recycling bin and the storage bucket are connected through the through groove.

[0013] Furthermore, the lead screw is rotatably located inside the storage tank, and the lead screw passes through the storage tank and extends to the outside, with a handle at one end of the lead screw.

[0014] Furthermore, the baffle thread is located on the outside of the lead screw, the baffle is movably located inside the storage tank, and a processing valve is provided on one side of the storage tank.

[0015] Compared with the prior art, the beneficial effects of this utility model include:

[0016] 1. When oil and gas enter the recovery box through the air inlet pipe, they will pass through the separator membrane body and enter the condenser. Particulate impurities and colloidal impurities contained in the oil and gas will adhere to the separator membrane body. In order to prevent particulate impurities from clogging the separator membrane body and affecting the separation of oil and gas, the staff will start the explosion-proof motor, which will drive the scraper to move through the threaded rod. The protective pads on the scraper will gently scrape off the impurities on the separator membrane body. The scraped impurities will fall into the inclined trough for centralized treatment.

[0017] 2. The scraped-off impurities will fall from the inclined chute through the through chute into the storage tank. When a large amount of impurities are collected in the storage tank, the operator turns the handle to make the screw drive the baffle to move. The baffle can squeeze the impurities toward the processing valve. The operator can then transfer the impurities to other places for processing through the processing valve.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figure 1 - Figure 6As shown, this utility model provides a three-stage oil and gas recovery device based on membrane separation, including: a recovery tank 1, an air inlet pipe 2, a condenser 5, and a separation membrane body 7 on the recovery tank 1; a scraping assembly on the recovery tank 1, including an explosion-proof motor 6 on the recovery tank 1, a threaded rod 9 at the output end of the explosion-proof motor 6, a scraper 12 on the threaded rod 9, a protective pad 18 on the scraper 12, and a heating block 17 on the scraper 12; and a collection assembly on the recovery tank 1, including an inclined groove 14 on the recovery tank 1, a storage tank 3 on the recovery tank 1, a lead screw 19 on the storage tank 3, and a baffle 20 on the lead screw 19.

[0028] In the above scheme:

[0029] 1. By controlling the rotation of the explosion-proof motor 6, the scraper 12 can be moved up and down through the threaded rod 9, so that the scraper 12 can scrape off the impurities on the separation membrane body 7. The protective pad 18 can protect the separation membrane body 7 while ensuring the scraping effect.

[0030] 2. By setting the storage groove 11, the scraper 12 can be stored when the separation membrane body 7 does not need to be scraped, so as to avoid the scraper 12 affecting the separation of oil and gas. By setting the heating block 17, the scraper 12 can be heated, so as to heat the impurities that need to be scraped, so that the scraper 12 can scrape the impurities cleanly.

[0031] 3. The scraped impurities can smoothly pass through the through groove 8 into the storage tank 3 via the inclined surface of the inclined groove 14. The operator can rotate the handle 4 to make the screw 19 drive the baffle 20 to squeeze the impurities, so that the operator can transfer the impurities to other places for processing through the processing valve 15.

[0032] In this embodiment, the scraping assembly also includes two sets of sliding grooves 10 symmetrically arranged inside the recycling bin 1, a threaded rod 9 rotatably disposed in the sliding groove 10, and a slider 16 disposed outside the threaded rod 9, the slider 16 being movably disposed within the sliding groove 10.

[0033] In the above scheme, the movement of the scraper 12 can be restricted by the cooperation of the groove 10 and the slider 16.

[0034] In this embodiment, the slider 16 is fixedly connected to the scraper 12, and a storage groove 11 is provided on the top inner side of the recycling bin 1, which matches the scraper 12.

[0035] In the above solution: the scraper 12 can be stored in the storage slot 11 so that the scraper 12 will not affect the separation membrane body 7 when it is working.

[0036] In this embodiment, the protective pad 18 is disposed on the side of the scraper 12 near the separation membrane body 7, and the protective pad 18 is in contact with the separation membrane body 7.

[0037] In the above solution: by setting the protective pad 18, the scraper 12 can remove impurities on the separation membrane body 7 while avoiding damage to the separation membrane body 7.

[0038] In this embodiment, two sets of limiting plates 13 are symmetrically arranged on the side of the scraper 12 away from the storage groove 11.

[0039] In the above scheme, the setting of two sets of limiting plates 13 can prevent impurities from entering the interior of the chute 10 during the scraping process of the scraper 12, thereby restricting the movement direction of the impurities.

[0040] In this embodiment, the collection component also includes a through groove 8 at the bottom of the inclined groove 14, and the through groove 8 penetrates the recycling box 1, and the recycling box 1 and the storage bucket 3 are connected through the through groove 8.

[0041] In the above scheme: the through groove 8 facilitates the entry of impurities into the storage tank 3 through the inclined groove 14.

[0042] In this embodiment, the lead screw 19 is rotatably disposed inside the storage tank 3, and the lead screw 19 passes through the storage tank 3 and extends to the outside. One end of the lead screw 19 is provided with a handle 4.

[0043] In the above scheme, the handle 4 makes it easier for staff to control the lead screw 19 to rotate stably.

[0044] In this embodiment, the baffle 20 is threaded on the outside of the lead screw 19, and the baffle 20 is movably disposed inside the storage tank 3. A processing valve 15 is provided on one side of the storage tank 3.

[0045] In the above scheme: the rotation of the lead screw 19 can drive the baffle 20 to squeeze the impurities, and the staff can open the processing valve 15 to facilitate the transfer of the impurities to other places.

[0046] In this embodiment, when oil and gas enter the recovery box 1 through the air inlet pipe 2, the separation membrane body 7 separates the oil and gas. Impurities will adhere to the separation membrane body 7 on the side near the air inlet pipe 2. The operator starts the explosion-proof motor 6, which drives the threaded rod 9 to rotate. The rotation of the threaded rod 9 drives the slider 16 to slide in the slide groove 10, thereby causing the scraper 12 to slide out of the collection groove 11. The movement of the scraper 12 can scrape off the impurities on the separation membrane body 7. During the scraping process, the limiting plates 13 set on both sides of the scraper 12 can prevent impurities from entering the slide groove 10, allowing the impurities to enter the inclined groove 14. The storage tank 3 is connected to the recovery box 1 through the through groove 8. The impurities enter the storage tank 3 through the through groove 8. The operator turns the handle 4, which drives the screw 19 to rotate, thereby driving the baffle 20 to squeeze the impurities, causing the impurities to move towards the processing valve 15. The operator opens the processing valve 15, which makes it easy for the operator to transfer the impurities to other places for processing.
