[0020] Beneficial effects of the present invention:

[0021] (1) When in use, the oil and gas are first placed in a low-temperature environment so as to be liquefied into droplets for easy recovery. Then, the support heat conduction plate and the support air guide plate are evenly arranged at equal intervals, so that the oil and gas have sufficient time to be liquefied, and the droplets have sufficient contact times to be fully attached to the side surfaces of the support heat conduction plate and the support air guide plate. The flow of the oil and gas is affected by the pressure gradient force rather than the driving force of the mechanical structure, so that the oil and gas can flow rapidly in a non-contact manner, and avoid the oil and gas adhering to the surface of other components to form a state that is difficult to clean, thereby reducing the difficulty of cleaning the overall structure. Each time cleaning is performed, the oily surfaces of the side sealing plate and the first scraper plate are brought close to the corresponding support scraper box, which can not only avoid the cleaning process from hindering recovery, but also allow the oil to be fully scraped off and concentrated together. Then, the second scraper plate scrapes off the oil in the direction of gravity and concentrates it in the recovery pipe network, so that the recovery rate of the oil is optimal, and the recovery difficulty is greatly reduced, and the recovery effect is excellent. Even the oil attached to the surface of the scraped component can be completely cleaned without residue.

[0022] (2) During operation, the elastic force of the sealing spring maintains the contact and sealing between the side sealing plate and the side edges of the supporting heat conducting plate and the supporting air guiding plate, thereby preventing the oil and gas from deviating from the return path. The first transmission rod pushes the unsealing transmission block, so that the side sealing plate can maintain a fixed distance from the first scraper plate, facilitating the downward movement of the second scraper plate to scrape the oil. The transmission process is simple and efficient, the structure is simple and easy to maintain, and the overall failure rate is reduced;

[0023] (3) During operation, the sealing cloth roll slides in the sealing groove to seal the transmission box, preventing oil and gas from entering, maintaining efficient transmission and reducing the overall failure rate;

[0024] (4) During operation, the uniformly staggered arrangement of air guide wedges further causes more turns and oscillations in the flow path of the oil and gas, further improving the efficiency of oil droplet attachment, so that the oil and gas can attach immediately after forming droplets, and the linear decrease of temperature with the linear arrangement of position is used to classify materials with different boiling points and concentrate them in different areas, and then guide them to the recovery network through different liquid guide grooves, and finally fill them into classified storage tanks through each independent guide channel in the recovery network. The whole process is simple, efficient and easy to obtain, and can simultaneously achieve the three goals of liquefaction, classification and complete recovery. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] When the present embodiment is working, the internal air of the cylindrical structure formed by the supporting oil scraper box 101, the supporting refrigeration plate 102, and the supporting bottom plate 103 is extracted to the outside through the exhaust fan 111, so that a low-pressure area is formed at the end where the exhaust fan 111 is located, and an air pressure gradient force is generated, so that the outside air at the other end of the cylindrical structure continues to flow into the cylindrical structure. When the oil and gas are recovered, the oil and gas are sealed and connected with the other end of the cylindrical structure through the pipeline, and the oil and gas are cooled by the supporting refrigeration plate 102 and the supporting heat conduction plate 104, and the air guide plate 105 is increased. The oil and gas repeatedly change their flow direction so that the oil in the oil and gas is liquefied and attached to the lower surface of the supporting refrigeration plate 102, the side surface of the supporting heat conduction plate 104, the side surface of the supporting air guide plate 105, the side surface of the first scraper plate 106, and the side surface of the side sealing plate 107 away from the first scraper plate 106. At the same time, by extending the length of the cylindrical structure and the density of the supporting heat conduction plate 104 and the supporting air guide plate 105, the flow time of the oil and gas in the cylindrical structure is extended, so that the oil can be fully cooled, liquefied and attached. Then, the first scraper plate 106 is removed from one of the The oil-staining surfaces of the first oil scraper 106 and the oil-staining surfaces of the side sealing plate 107 with oil stains are moved from one side sealing plate 107 to another side sealing plate 107, and the oil-staining surfaces of the first oil scraper 106 and the oil-staining surfaces of the side sealing plate 107 with oil stains are just located under the two sides of the second oil scraper 108. The other side sealing plate 107 is in contact with the side edges of the supporting refrigeration plate 102, the supporting bottom plate 103, the supporting heat conduction plate 104 and the supporting air guide plate 105 to form a contact seal. At the same time, the oil stains scraped by the first oil scraper 106 are moved along the The side surface of the first scraper plate 106 naturally flows to the guide support seat 109 under the force of gravity, and then the second scraper plate 108 on this side moves downward to scrape and clean the oily surface of the first scraper plate 106 and the side sealing plate 107. After the cleaning is completed, the oil is discharged along the recovery pipe network 110, and the second scraper plate 108 is reset. Then the first scraper plate 106 moves in the opposite direction and cleans and discharges all the oil on the other side. This process is repeated to fully liquefy and remove the oil in the oil and gas, and the remaining gas that cannot be liquefied is discharged to the next link for corresponding harmless treatment.

[0039] Both ends of the first scraper 106 are provided with a transmission box 201, a first transmission rod 202 is movably provided in the transmission box 201, the first transmission rod 202 is fixedly connected to the first scraper 106, a first slide groove 203 is provided in the middle of the transmission box 201 to cooperate with the sliding of the first transmission rod 202, a first connecting rod 204 is fixedly connected to the upper side of the middle of the first transmission rod 202, and a transmission slide groove 205 is provided on the top of the transmission box 201 to cooperate with the sliding of the first connecting rod 204;

[0040] An unsealing chute 206 is provided at both ends of the transmission box 201 and at the lower side of the end of the first chute 203, and an unsealing transmission block 207 is slidably connected in the unsealing chute 206. The upper end of the unsealing transmission block 207 is located in the first chute 203 and is flush with the end of the first connecting rod 204. A sealing spring 208 is installed between the middle part of one side of the unsealing transmission block 207 and the groove wall of the unsealing chute 206. An unsealing transmission rod 209 is fixedly connected to the lower part of the other side of the unsealing transmission block 207. The end of the unsealing transmission rod 209 is fixedly connected to a second transmission rod 211, and the second transmission rod 211 is fixedly connected to the side frame of the side sealing plate 107. Second chute 210 cooperating with the unsealing transmission rod 209 and the second transmission rod 211 for sliding is provided at both ends of the transmission box 201. One side of the second chute 210 passes through the transmission box 201 and the support oil scraper box 101 in sequence;

[0041] When this embodiment is working, by moving the first connecting rod 204, the first transmission rod 202 slides in the first slide groove 203, thereby driving the first scraper plate 106 to move back and forth left and right, and at the same time scraping oil and concentrating oil stains. When approaching the side sealing plate 107 on one side, the first transmission rod 202 first pushes the unsealing transmission block 207 on that side, and then pushes the unsealing transmission rod 209 and the second transmission rod 211, so that the side sealing plate 107 on this side no longer abuts the supporting heat conducting plate 104 and the supporting air guide plate 105 and keeps a distance from the first scraper plate 106, and at the same time stretches the sealing spring 208 to generate elastic force. When the first scraper plate 106 moves away, the elastic force of the sealing spring 208 resets the unsealing transmission block 207, so that the side sealing plate 107 abuts against the supporting heat conducting plate 104 and the supporting air guide plate 105 again after cleaning and generates a contact seal.

[0042] An installation cavity 212 is provided in the transmission box 201 and located above the second slide groove 210, and an installation shaft 213 is installed in the middle of the installation cavity 212. Both ends of the installation shaft 213 are elastically rotatably connected to the installation cavity 212 through hinged coil springs 214. A sealing cloth roll 215 is wound around the middle of the installation shaft 213. Sealing grooves 216 are provided in the transmission box 201 and located in the groove walls on both sides of the first slide groove 203. Both ends of the sealing grooves 216 are mutually connected with the corresponding installation cavity 212 on each side. The sealing cloth roll 215 passes through the sealing groove 216 and its two ends are fixedly connected to the corresponding installation shaft 213 respectively. The first transmission rod 202 passes through the middle of the sealing cloth roll 215 and is sealed and fixedly connected to it. The side of the sealing cloth roll 215 is sealed and slidably connected with the sealing groove 216.

[0043] When this embodiment is working, the sealing cloth roll 215 moves synchronously with the sliding of the first transmission rod 202, and the mounting shaft 213 is rotated by the elastic force of the hinged coil spring 214 to reel in the sealing cloth roll 215. The sealing cloth roll 215 is isolated from the inside and outside of the transmission box 201 through sealing sliding to prevent oil and gas from entering.

[0044] A first power box 301 is installed on the upper part of the transmission box 201, and first motors 302 are installed at both ends of the first power box 301. A first screw rod 303 is installed between the driving shafts of the two first motors 302. A first slider 304 is threadedly sleeved on the first screw rod 303. The first slider 304 is slidably connected to the inner wall of the first power box 301, and the first slider 304 is fixedly connected to the first connecting rod 204;

[0045] During operation, the first motor 302 drives the first screw rod 303 to push the first slider 304 to move back and forth, thereby pushing the first oil scraper 106 to move back and forth through the first connecting rod 204 .

[0046] A second power box 401 is installed on the top of the support oil scraper box 101, and the two second power boxes 401 are symmetrical to each other. A second motor 402 is installed on the inner top of the second power box 401, and a second screw rod 403 is installed on the lower end of the driving shaft of the second motor 402. A transmission slide plate 404 is threadedly sleeved on the second screw rod 403, and a plurality of equidistant and evenly distributed transmission pressure rods 405 are fixedly connected to the lower surface of the transmission slide plate 404. The lower end of the transmission pressure rod 405 passes through the second power box 401 and the support oil scraper box 101, and the transmission pressure rod 405 is fixedly connected to the second oil scraper plate 108;

[0047] During operation, the second motor 402 rotates the second screw rod 403, moves the transmission slide plate 404 up and down, and pushes the transmission pressure rod 405 to push down the second scraper plate 108. Through a plurality of equidistant and evenly distributed transmission pressure rods 405, the transmission torque is evenly distributed, maintaining the horizontal downward movement of the second scraper plate 108, avoiding deformation of the second scraper plate 108, and preventing incomplete cleaning.

[0048] A plurality of liquid guiding grooves 501 evenly distributed in a rectangular array are provided in the guide support seat 109, and each row of liquid guiding grooves 501 is respectively and correspondingly located directly below the side of the second oil scraper 108, and the recovery pipe network 110 is provided with a plurality of mutually independent guiding channels, and the guiding channels of the recovery pipe network 110 correspond one-to-one to the liquid guiding grooves 501;

[0049] Wind guide wedges 502 are installed on both sides of the supporting heat conducting plate 104 and the supporting air guide plate 105, and the wind guide wedges 502 of the supporting heat conducting plate 104 and the supporting air guide plate 105 are evenly staggered;

[0050] A serpentine tube 503 is embedded in the supporting refrigeration plate 102, and a heat insulation plate 505 is attached to the upper periphery of the supporting refrigeration plate 102. Both ends of the heat insulation plate 505 are embedded with connecting pipe heads 504, and the serpentine tube 503 is connected to the refrigerant through the connecting pipe heads 504;

[0051] When the present embodiment is working, the evenly staggered arrangement of the air guide wedges 502 further allows the liquefied oil and gas droplets to be more fully attached to the surfaces of the supporting heat conducting plate 104, the supporting air guide plate 105 and the air guide wedge 502. The serpentine tube 503 prolongs the time for the refrigerant to pass through, so that the refrigerant can fully absorb heat and evaporate. At the same time, the refrigerant is continuously transported in the serpentine tube 503 from the direction close to the exhaust fan 111 to the direction away from it. The serpentine tube 503 is provided with a plurality of straight sections, and the straight sections of the serpentine tube 503 are parallel to the supporting heat conducting plate 104 and the supporting air guide plate 105, so that the temperature is lower at a position closer to the serpentine tube 503. , and the temperature rises in a gradient according to the distance, so that the oil and gas continuously releases heat and cools down when it returns. At the same time, the oil with different boiling points in the oil and gas is successively reduced to their respective boiling points as the temperature points decrease, and is successively liquefied in different areas and attached to the supporting heat conduction plate 104, the supporting air guide plate 105 and the air guide wedge 502 in the corresponding area, and then guided to the recovery pipe network 110 through different liquid guide grooves 501, and classified and guided through each independent guiding channel in the recovery pipe network 110 and finally filled into the classified storage tanks, thereby simultaneously achieving the three goals of liquefaction, classification and complete recovery, which is simple, efficient and easy to obtain.

[0052] When the present invention is used, the oil and gas are first placed in a low-temperature environment so as to be liquefied into droplets for easy recovery. Subsequently, the support heat conducting plate 104 and the support air guide plate 105 are evenly arranged at equal intervals, so that the oil and gas have sufficient time to be liquefied, and the droplets have sufficient contact times to be fully attached to the side surfaces of the support heat conducting plate 104 and the support air guide plate 105. The flow of the oil and gas is affected by the pressure gradient force rather than the driving force of the mechanical structure, so that the oil and gas can flow rapidly in a non-contact manner, and the oil and gas can be prevented from being attached to the surface of other components to form The state that is difficult to clean reduces the cleaning difficulty of the overall structure. Each time cleaning is performed, the oily surfaces of the side sealing plate 107 and the first scraper plate 106 are brought close to the corresponding support scraper box 101, which can not only avoid the cleaning process from hindering the recovery, but also make the oily dirt fully scraped and concentrated together. Then the second scraper plate 108 scrapes the oily dirt in the direction of gravity and concentrates it in the recovery pipe network 110, so that the recovery rate of the oily dirt reaches the best, and the recovery difficulty is greatly reduced, and the recovery effect is excellent. Even the oily dirt attached to the surface of the scraped parts can be completely cleaned without any residue;

[0053] During operation, the elastic force of the sealing spring 208 maintains the contact and sealing between the side sealing plate 107 and the side edges of the supporting heat conducting plate 104 and the supporting air guiding plate 105, thereby preventing the oil and gas from deviating from the return path. The first transmission rod 202 pushes the unsealing transmission block 207, so that the side sealing plate 107 can maintain a fixed distance with the first oil scraping plate 106, which facilitates the downward movement of the second oil scraping plate 108 to scrape the oil. The transmission process is simple and efficient, the structure is simple and easy to maintain, and the overall failure rate is reduced.

[0054] During operation, the sealing cloth roll 215 slides in the sealing groove 216 to seal the transmission box 201, thereby preventing oil and gas from entering, maintaining efficient transmission, and reducing the overall failure rate;

[0055] During operation, the evenly staggered arrangement of the air guide wedges 502 further causes more turns and oscillations in the flow path of the oil and gas, further improving the efficiency of the oil droplet attachment, so that the oil and gas can attach immediately after the droplets are formed, and the effect of the linear decrease of temperature with the linear arrangement of the position is utilized to classify the materials with different boiling points and concentrate them in different areas, and then guide them to the recovery network 110 through different liquid guide grooves 501, and classify and guide them through the independent guiding channels in the recovery network 110 and finally fill them into the classified storage tanks. The whole process is simple, efficient and easy to obtain, and can simultaneously achieve the three goals of liquefaction, classification and complete recovery.

Each guiding channel of the recovery pipe network 110 is connected to a filling machine, and each filling machine is independent of each other. The exhaust fan 111 is connected to an exhaust gas absorption tower.
