Description

Technical Field

[0001] The present invention relates to the technical field of oil-gas separation, and specifically to an oil-gas recovery device with a condensation mechanism. Background Art

[0002] Oil-gas recovery devices are environmental protection devices designed for problems such as oil-gas volatilization in gas stations, oil depots, refineries, etc. Through technologies such as condensation, adsorption, absorption, or membrane separation, the volatilized oil-gas is separated from the air and liquefied for recovery. This can not only reduce VOCs emissions and improve air quality, but also recover resources, reduce operating costs, and at the same time reduce the risk of fire and explosion, meeting the requirements of environmental protection regulations;

[0003] In the industrial process of applying membrane separation technology to oil-gas separation and recovery, with the accumulation of operation time, pollutants will inevitably remain on the surface of the membrane separation unit. These pollutants include oil droplets, gums, particulate matter, and chemical deposits, which attach to the membrane pores or surface through physical adsorption, chemical bonding, or mechanical blockage, gradually reducing the permeation flux and selectivity of the membrane, and thus affecting the oil-gas recovery efficiency and product quality. Therefore, to maintain the stable operation of the membrane separation system, it is necessary to regularly clean the pollutants on the membrane module. However, currently, the cleaning method of the membrane separation unit mainly relies on manually removing the membrane parts from the inside of the recovery device for off-line cleaning. Frequent disassembly and installation of the membrane module will not only cause the sealing structure of the membrane module to be prone to aging, deformation, or damage during frequent disassembly, reducing the oil-gas recovery rate, but also pose safety hazards, such as the risk of fire or explosion caused by oil-gas leakage. Moreover, the membrane material is prone to being damaged due to improper operation by the staff during the disassembly process, destroying the pore structure of the membrane, resulting in uneven pore size distribution, and even generating through-cracks, further reducing the oil-gas recovery rate and shortening the service life of the membrane parts.

[0004] Therefore, the present invention proposes an oil-gas recovery device with a condensation mechanism to solve the above problems. Summary of the Invention

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides an oil and gas recovery device with a condensing mechanism, having the following beneficial effects:

[0021] 1. Through the provided membrane pollutant separation mechanism, the separation membrane can achieve reciprocating relaxation and vibration in the separation box. The reciprocating vibration of the separation membrane generates a periodic shear force between the pollutant and the surface of the separation membrane, which can weaken the adsorption effect between the pollutant and the membrane pore wall, directly strip the pollutants on the surface of the separation membrane. Not only does it eliminate the need for manual disassembly of the membrane module, eliminate the risk of aging, deformation or damage of the sealing structure of the separation membrane, prevent potential fire or explosion hazards caused by oil and gas leakage, but also avoid damage to the membrane pore structure caused by improper operation, ensure uniform pore size distribution, maintain high separation performance, extend the service life of the separation membrane, and improve the stability of oil and gas separation.

[0022] 2. Through the provided sealing plate, during the oil and gas recovery process, the sealing performance between the sliding plate and the fixing plate can be improved, avoiding the leakage of untreated oil and gas through the gap between the sliding plate and the fixing plate. If untreated oil and gas leaks through the gap, it may cause fire or explosion. The sealing plate ensures that the oil and gas completely pass through the separation and treatment path through physical barrier, avoiding leakage to the outside of the separation box or untreated area, reducing the risk of poisoning for workers, and at the same time avoiding air pollution and reducing the damage of volatile organic compounds to the ozone layer and air quality.

[0023] 3. Through the arranged turntable, cylinder, push plate, slider, fixed column, lifting plate, vertical plate, lifting block, lifting column and compression plate, during the process of treating pollutants by the loosening and vibrating of the separation membrane, the air inside the compressed air jet box can be sprayed above the separation membrane, blowing the pollutants above the separation membrane to one side, reducing the accumulation of pollutants on the separation membrane. This can not only reduce the degree of pollution of the separation membrane, maintain the permeability of the separation membrane, and extend the service life of the separation membrane, but also blow the pollutants to one side in time, avoiding the long-term stay of pollutants above the separation membrane, the occurrence of chemical reactions or biological growth, and the occurrence of secondary pollution of the separation membrane, thus ensuring the quality of the oil and gas after treatment.

[0024] 4. Through the arranged membrane function detection mechanism, when the separation membrane is blocked, it can pull the first contact and the second contact to separate and turn on the alarm for operation. The staff can not only know in time that the separation membrane is blocked, avoid the situation that the blockage causes the permeability of the separation membrane to decrease and the oil and gas separation efficiency to decrease, so that the separation membrane can be cleaned or replaced in time to restore its normal separation ability, maintain the separation performance of the separation membrane, and ensure the oil and gas treatment effect, but also the staff can stop the oil and gas separation in time to avoid damage to the separation membrane due to excessive pressure, thereby extending the service life of the separation membrane.

[0038] An oil and gas recovery device with a condensation mechanism in this embodiment, as Figure 1 - Figure 8 shown, includes a recovery box 1. An oil pot 9 and a separation box 5 are fixedly connected inside the recovery box 1. An intake pipe 2 is fixedly connected to the outer surface of the oil pot 9.

A fixing plate 14 is fixedly connected inside the separation box 5. An activated carbon adsorption plate 15 is fixedly connected to the fixing plate 14. A separation membrane 13 is arranged between the activated carbon adsorption plate 15 and the connecting pipe 11. It also includes a membrane pollutant separation mechanism and a membrane function detection mechanism. The membrane pollution separation mechanism includes symmetrically arranged connecting plates 614. The connecting plates 614 are fixedly connected to both sides of the separation membrane 13. A sliding plate 613 is fixedly connected to the connecting plate 614 on the side close to the fixing plate 14. The sliding plate 613 penetrates and is slidably connected to the fixing plate 14. The other connecting plate 614 is connected to the inner wall of the separation box 5. The membrane pollutant separation mechanism is used to remove the pollutants attached to the upper surface of the separation membrane 13.

[0039] In this embodiment, as Figure 6 shown, a linkage plate 617 is rotatably connected to the side of the skateboard 613 away from the connecting plate 614. One end of the linkage plate 617 away from the skateboard 613 is rotatably connected through a linkage rod 616. A rotating shaft 612 is fixedly connected to the linkage rod 616. One end of the rotating shaft 612 is fixedly connected to a driving motor 618. The driving motor 618 is fixedly connected to the side wall of the separation box 5. When the driving motor 618 drives the rotating shaft 612 to rotate, through the provided linkage rod 616 and linkage plate 617, the skateboard 613 can be pushed to slide reciprocally through the fixed plate 14 synchronously.

[0040] In this embodiment, as Figure 6 shown, sealing plates 615 are symmetrically and fixedly connected to the side of the connecting plate 614 close to the skateboard 613. The sealing plates 615 are respectively clamped with the fixed plate 14. By the mutual clamping of the provided sealing plates 615 and the fixed plate 14, the sealing performance between the skateboard 613 and the fixed plate 14 can be improved.

[0041] In this embodiment, as Figure 3 and Figure 7 shown, an air jet box 602 is fixedly connected through the separation box 5. Air outlet holes 619 are equidistantly arranged on the side of the air jet box 602 close to the separation box 5. Air inlet holes 603 are equidistantly arranged on the side of the air jet box 602 away from the separation box 5. Check valves are arranged inside both the air inlet holes 603 and the air outlet holes 619. The air jet box 602 can inhale external air into the air jet box 602 through the air inlet holes 603 and then blow it into the separation box 5 again through the air outlet holes 619.

[0042] In this embodiment, as Figure 3 and Figure 7 shown, a compression plate 620 is slidably connected up and down inside the air jet box 602. An elevating column 621 is fixedly connected to the upper end surface of the compression plate 620. The elevating column 621 is slidably connected through the air jet box 602. An elevating block 604 is fixedly connected to the upper end of the elevating column 621. A vertical plate 605 is fixedly connected to the side of the elevating block 604 away from the separation box 5. When the vertical plate 605 drives the elevating block 604 to move up and down reciprocally, through the provided elevating column 621, the compression plate 620 can be driven to move up and down synchronously inside the air jet box 602.

[0043] In this embodiment, as Figure 3 and Figure 4As shown, a cross-rail 610 is fixedly connected to one side of the separation box 5 close to the jet box 602. The cross-rail 610 is located below the jet box 602. A slider 611 is slidably connected to the cross-rail 610. A fixing column 609 is fixedly connected to the side of the slider 611 away from the separation box 5. A jacking plate 606 is rotatably connected to the outer surface of the fixing column 609. One end of the jacking plate 606 away from the fixing column 609 is rotatably connected to the vertical plate 605. When the slider 611 slides horizontally on the cross-rail 610, the fixing column 609 can drive the lower end of the jacking plate 606 to move horizontally synchronously, so that the jacking plate 606 reciprocates between an inclined state and a vertical state, and pushes the vertical plate 605 connected to one end of the jacking plate 606 away from the fixing column 609 to perform reciprocating up and down movements.

[0044] In this embodiment, as Figure 4 and Figure 5 shown, a push plate 608 is rotatably connected to the outer surface of the fixing column 609. A cylinder 607 is rotatably connected through one end of the push plate 608 away from the fixing column 609. A turntable 601 is fixedly connected to one end of the cylinder 607 close to the separation box 5. The cylinder 607 is located at the edge of the turntable 601. The turntable 601 is fixedly connected to the rotating shaft 612. When the rotating shaft 612 drives the turntable 601 to rotate, the cylinder 607 connected to the edge of the turntable 601 can push the push plate 608 to drive the fixing column 609 to move synchronously, and drive the slider 611 connected to the fixing column 609 to move synchronously.

[0045] In the prior art, the cleaning method of the membrane separation unit mainly relies on manually removing the membrane parts from the inside of the recovery equipment for off-line cleaning. Frequent disassembly and installation of the membrane module will not only cause the sealing structure of the membrane module to be prone to aging, deformation or damage during frequent disassembly, reducing the oil and gas recovery rate, but also pose safety hazards, such as the risk of fire or explosion caused by oil and gas leakage. Moreover, the membrane material is prone to damage during the disassembly process due to improper operation by the staff, damaging the pore structure of the membrane, resulting in uneven pore size distribution, and even generating through cracks, further reducing the oil and gas recovery rate and shortening the service life of the membrane parts. Compared with the prior art, the separation membrane 13 can realize reciprocating loosening and vibrating in the separation box 5. The reciprocating vibration of the separation membrane 13 generates a periodic shear force between the pollutants and the surface of the separation membrane 13, which can weaken the adsorption effect between the pollutants and the membrane pore wall and directly peel off the pollutants on the surface of the separation membrane 13. Not only does it not require manual disassembly of the membrane module, eliminating the risk of aging, deformation or damage to the sealing structure of the separation membrane 13 and preventing the fire or explosion hazards caused by oil and gas leakage, but also avoids the damage to the membrane pore structure caused by improper operation, ensures uniform pore size distribution, maintains high separation performance, extends the service life of the separation membrane 13, and improves the stability of oil and gas separation.

[0046] In this embodiment, as Figure 8As shown, a second contact 706 is fixedly connected to one side of the connecting plate 614 close to the hollow plate 702. A first contact 705 is in contact with the side of the second contact 706 away from the connecting plate 614. The first contact 705 is fixedly connected to the inner side wall of the separation box 5. An alarm 701 is electrically connected between the first contact 705 and the second contact 706. The alarm 701 is fixedly connected to the upper end face of the separation box 5. When the connecting plate 614 pulls the second contact 706 and the first contact 705 to be separated, the alarm 701 can be turned on to work.

[0047] In this embodiment, as Figure 2 shown, a condensing pipe 10 is fixedly connected through the inside of the oil pot 9. A heat exchanger is fixedly connected to the condensing pipe 10. By cooling the high-concentration oil and gas inside the oil pot 9 through the condensing pipe 10, the high-concentration oil and gas can be condensed into a liquid.

[0048] Compared with the prior art, when the separation membrane 13 is blocked, the first contact 705 and the second contact 706 can be pulled to be separated, and the alarm 701 is turned on to work. The staff can not only know in time that the separation membrane 13 is blocked, avoid the decrease in the permeability of the separation membrane 13 caused by the blockage, and reduce the occurrence of the situation of reducing the oil and gas separation efficiency, so that the separation membrane 13 can be cleaned or replaced in time to restore its normal separation ability, maintain the separation performance of the separation membrane 13, and ensure the oil and gas treatment effect. Moreover, the staff can stop the oil and gas separation in time to avoid damage to the separation membrane 13 due to excessive pressure, thereby prolonging the service life of the separation membrane 13.

[0049] The working process and principle involved in the overall content of the above embodiment are as follows:

[0050] It should be noted that the separation membrane 13 is a flexible membrane.

[0051] When the staff needs to process oil and gas recovery, first turn on the air extractor 8 connected to the intake pipe 2, draw the oil and gas into the oil pot 9 through the intake pipe 2, and then turn on the heat exchanger connected to the condenser pipe 10, so that the condenser pipe 10 cools the high-concentration oil and gas in the oil pot 9 to condense it into a liquid. After the high-concentration oil and gas condensation is completed, the staff can turn on the air extractor 8 connected to the recovery pipe 3, and inhale the residual oil and gas in the oil pot 9 into the separation box 5 through the connecting pipe 11. After the oil and gas enters the separation box 5, through the air extractor 8 connected to the recovery pipe 3, it will first come into contact with the separation membrane 13 connected to the separation box 5, so that the volatile organic compounds in the oil and gas are separated from the air. The volatile organic compounds will pass through the separation membrane 13 and be recovered through the recovery pipe 3. The air separated from the organic compounds will pass through the activated carbon adsorption plate 15 and be discharged through the exhaust pipe 4. After the organic compound recovery is completed, then open the valve at the lower end of the oil pot 9, so that the cooled liquid inside the oil pot 9 flows into the recovery pipe 3 through the connecting pipe 11 for recovery;

[0052] During the process of the organic compounds in the oil and gas passing through the separation membrane 13 under the influence of the air extractor 8 connected to the recovery pipe 3, if the separation membrane 13 is used for a long time and the surface residual pollutants hinder the passage of the organic compounds, the air extractor 8 will suck the organic compounds to squeeze the separation membrane 13, causing the separation membrane 13 to bend downward from the horizontal state. At this time, the separation membrane 13 will pull the connecting plate 614 connected to the side close to the hollow plate 702 to move, and drive the extension plate 704 to slide out from the inside of the hollow plate 702. During the separation process of the connecting plate 614 and the hollow plate 702, the connecting plate 614 will drive the second contact 706 connected to the side close to the hollow plate 702 to separate from the first contact 705. After the first contact 705 and the second contact 706 are completely separated, through the alarm 701 electrically connected between the first contact 705 and the second contact 706, the alarm 701 can be turned on to work. The staff can not only timely know that the separation membrane 13 is blocked, avoid the situation that the blockage causes the permeability of the separation membrane 13 to decrease and the oil and gas separation efficiency to decrease, so as to timely clean or replace the separation membrane 13, restore its normal separation ability, maintain the separation performance of the separation membrane 13, and ensure the oil and gas treatment effect, but also the staff can timely stop the oil and gas separation to avoid damage to the separation membrane 13 due to excessive pressure, thereby prolonging the service life of the separation membrane 13;

[0053] When pollutants remaining on the surface of the separation membrane 13 hinder the separation and recovery of oil and gas, the staff can turn on the drive motor 618 to drive the rotating shaft 612 to rotate on the separation tank 5, and drive the linkage rod 616 connected to the rotating shaft 612 to move around the rotating shaft 612 as the center. Since the linkage plate 617 is rotatably connected to the outer surface of the linkage rod 616, and one end of the linkage plate 617 away from the linkage rod 616 is rotatably connected to the side wall of the sliding plate 613, therefore, as the linkage rod 616 rotates, the sliding plate 613 can be pushed to slide reciprocally through the fixed plate 14 by the linkage plate 617. When the sliding plate 613 slides towards the separation membrane 13, through the connecting plate 614 connected between the sliding plate 613 and the separation membrane 13, the separation membrane 13 can be moved from the tensioned state to the relaxed state. When the sliding plate 613 slides on the fixed plate 14 towards the linkage rod 616, the separation membrane 13 can be pulled again from the relaxed state to the tensioned state through the connecting plate 614. Thus, during the continuous rotation of the rotating shaft 612, the separation membrane 13 can achieve reciprocating tension and relaxation vibration in the separation tank 5. The reciprocating vibration of the separation membrane 13 generates a periodic shear force between the pollutants and the surface of the separation membrane 13, which can weaken the adsorption effect between the pollutants and the membrane pore wall and directly peel off the pollutants on the surface of the separation membrane 13. This not only eliminates the need for manual disassembly of the membrane module, reduces the risk of aging, deformation or damage to the sealing structure of the separation membrane 13, and eliminates the potential fire or explosion hazards caused by oil and gas leakage, but also avoids the damage to the membrane pore structure caused by improper operation, ensures uniform pore size distribution, maintains high separation performance, extends the service life of the separation membrane 13, and improves the stability of oil and gas separation;

[0054] During the rotation of the rotating shaft 612, the turntable 601 connected to the end of the rotating shaft 612 far from the driving motor 618 will rotate synchronously. Since the cylinder 607 connected to the side wall of the turntable 601 is located at the edge of the turntable 601, the cylinder 607 will move synchronously with the rotation of the turntable 601 with the rotating shaft 612 as the center. As the cylinder 607 moves, the cylinder 607 will push one end of the push plate 608 to move synchronously. When one end of the push plate 608 is subjected to a thrust force, it will push the fixed column 609 rotatably connected to the end far from the cylinder 607 to drive the slider 611 to reciprocate horizontally on the cross rail 610. Since the end of the fixed column 609 far from the slider 611 is rotatably connected to the jacking plate 606, and the end of the jacking plate 606 far from the fixed column 609 is rotatably connected to the vertical plate 605, and the vertical plate 605 is fixedly connected to the side wall of the lifting block 604, and the lower end of the lifting block 604 is connected to the lifting column 621, during the horizontal reciprocating movement of the slider 611, the slider 611 will drive the lifting column 621 to penetrate and slide up and down synchronously on the jet box 602 through the fixed column 609, the jacking plate 606, the vertical plate 605 and the lifting block 604. When the lifting column 621 rises, the lifting column 621 will pull the compression plate 620 connected to the lower end to rise synchronously inside the jet box 602, so that the compression plate 620 will suck the external air of the jet box 602 into the jet box 602 through the air inlet hole 603 for storage. When the lifting column 621 descends, the lifting column 621 will push the compression plate 620 to descend synchronously. At this time, the air inside the jet box 602 will be ejected from the air outlet hole 619 opened on the jet box 602 through the extrusion of the compression plate 620, and sprayed above the separation membrane 13, blowing the pollutants above the separation membrane 13 to one side, reducing the accumulation of pollutants on the separation membrane 13. This can not only reduce the degree of pollution of the separation membrane 13, maintain the permeability of the separation membrane 13, and extend the service life of the separation membrane 13, but also blow the pollutants to one side in time, avoiding the long-term stay of pollutants above the separation membrane 13, resulting in chemical reactions or biological growth, and preventing the occurrence of secondary pollution of the separation membrane 13, thereby ensuring the quality of the oil and gas after treatment;

[0055] When the staff member turns off the drive motor 618, the rotating shaft 612 connected to the drive motor 618 rotates a complete number of turns. At this time, the rotating shaft 612 will pull the connecting plate 614 to fit against the side wall of the fixed plate 14 through the linkage rod 616, the linkage plate 617 and the sliding plate 613, so that the sealing plate 615 symmetrically connected to the side of the connecting plate 614 close to the fixed plate 14 is clamped onto the fixed plate 14, improving the sealing performance between the sliding plate 613 and the fixed plate 14 and preventing the untreated oil and gas from leaking through the gap between the sliding plate 613 and the fixed plate 14. If the untreated oil and gas leaks through the gap, it may cause a fire or explosion. The sealing plate 615 ensures that the oil and gas completely passes through the separation and treatment path through physical blockage, preventing leakage to the outside of the separation tank 5 or the untreated area, reducing the risk of poisoning of the staff member, and at the same time avoiding air pollution and reducing the damage of volatile organic compounds to the ozone layer and air quality.
