[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In addition, when an element in the present invention is referred to as being "disposed on" or "disposed on" another element, it may be directly on the other element or there may be a centered element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a centered element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0029] See also Figure 1-Figure 10 In an embodiment of the present invention, a medium condensed oil gas recovery device with switchable heating and cooling includes a frame 1 and a cold box 2 installed on the frame 1, and also includes: The condensing pipe 3 is arranged in a serpentine shape, and a plurality of them are arranged in equal distances in the cold box 2. The plurality of condensing pipes 3 can swing synchronously, and a group of oil and gas through-hole mechanisms are respectively connected to both ends of the condensing pipe 3; A storage tank 18 is installed on the frame 1 and is used to store the droplets generated by condensation. The storage tank 18 is connected to a cold and hot dual-control pumping mechanism, and the cold and hot dual-control pumping mechanism is used to pump out the medium in the storage tank 18; The partition control mechanism is disposed on the storage tank 18 and is connected to the condensation pipe 3 through a drainage mechanism to form a recovery passage for the droplets in the condensation pipe 3, and the partition control mechanism can separate the recovery passage into two sections.

[0030] Furthermore, during operation, the temperature in the cold box 2 needs to be controlled in advance to ensure that the internal temperature of the cold box 2 meets the requirements for oil and gas condensation; Specifically, the oil and gas pass through the condensation pipe 3 through the oil and gas penetration mechanism, and after heat exchange, the temperature of the oil and gas in the condensation pipe 3 is reduced and condensed into liquid, and droplets are generated in the condensation pipe 3, and the droplets can flow out of the condensation pipe 3 through the drainage mechanism; The isolation control mechanism works to first block the upper section of the recovery passage to prevent oil and gas from entering the storage tank 18 to avoid losses, and then the lower section of the recovery passage is connected, so that the droplets in the upper section can enter the storage tank 18 for storage; When the cold and hot dual-control pumping mechanism is in operation, the condensed product in the storage tank 18 is pumped out.

[0031] In the above process, the plurality of condensing pipes 3 can synchronously reciprocate and swing in the cold box 2. Thus, on the one hand, the refrigerant medium in the cold box 2 can be mixed, thereby improving the uniformity of the distribution of the refrigeration temperature in the cold box 2. On the other hand, when the condensing pipe 3 reciprocates and swings, the droplets adhering to the inner wall of the condensing pipe 3 will be subjected to a certain centrifugal effect, thereby facilitating the aggregation of the droplets. When the amount of droplet aggregation reaches a certain level, it is easy to slide out of the condensing pipe 3 under the action of gravity, thereby improving the extraction efficiency of the condensate. In addition, it can also avoid the problem of crystallization caused by the droplets adhering to the inner wall of the condensing pipe 3 for a long time, which may reduce the oil and gas recovery rate at the least and cause the condensing pipe 3 to be blocked at the worst.

[0032] Please refer again Figure 7 The hot and cold dual-control pumping mechanism includes an oil pump 29 installed on the side of the frame 1, the oil inlet of the oil pump 29 is connected to the storage tank 18, the oil outlet is connected to an oil pipe, and the oil pipe is spirally wound with an electric heating belt 31 and a cooling bellows 32. The frame 1 is also provided with a cooling pump 30, the inlet and outlet of the cooling pump 30 are respectively connected to the cooling tank 2 and one end of the cooling bellows 32, and the other end of the cooling bellows 32 is connected to the cooling tank 2.

[0033] Furthermore, the condensed medium is collected in the storage tank 18, and when it is output to the outside through the oil pump 29, the required temperature is different due to different media, and it needs to be kept cold or warm. The electric heating tape 31 is spirally wound and attached to the oil pipeline to increase the temperature of the pipeline, and the cooling bellows 32 is spirally wound and attached to the oil pipeline to reduce the temperature of the pipeline to reach the required temperature of the oil pipeline, thereby avoiding crystallization blockage of the medium in the pipeline, avoiding the need for a lot of manpower to clean up after the blockage, and in serious cases, it will also cause the burning of electrical instruments and the motor of the oil pump, affecting the normal use of the equipment.

[0034] Please refer again Figure 6 and Figure 8 , a plurality of rotating shafts 4 are rotatably provided in the cold box 2, and the plurality of rotating shafts 4 are arranged opposite to each other in pairs, the condensing pipe 3 is connected to the rotating shafts 4, and one of the rotating shafts 4 is connected to the output end of the first driving motor 6 installed on the outer wall of the cold box 2; Two adjacent rotating shafts 4 are connected via a transmission belt 5 , a plurality of straight sections 301 are provided on the condensing pipe 3 , the straight sections 301 are connected to the drainage mechanism, and the central axes of the straight sections 301 and the rotating shaft 4 coincide with each other.

[0035] During the condensation recovery process, when the first driving motor 6 works, it can drive the condensation pipe 3 to reciprocate and swing through the rotating shaft 4, and the multiple condensation pipes 3 realize synchronous swinging action under the action of the transmission belt 5. Therefore, under the action of centrifugal force, it is beneficial to the aggregation of droplets adhered to the inner wall of the condensation pipe 3, thereby improving the extraction efficiency of the condensate. In addition, it can also avoid the problem of crystallization caused by the droplets adhering to the inner wall of the condensation pipe 3 for a long time, which may reduce the oil and gas recovery rate at the least and cause the condensation pipe 3 to be blocked at the worst.

[0036] Please refer again Figure 4 , Figure 5 as well as Figure 8 A guide groove 201 is provided on the side plate of the cold box 2, and a transverse plate 8 adapted to the guide groove 201 is sealed and slidably engaged in the guide groove 201. The length of the guide groove 201 is greater than the length of the transverse plate 8. The oil and gas penetration mechanism includes a box body 33 arranged on the side of the cold box 2, a plurality of fixed pipes 9 arranged on the transverse plate 8 and extending into the box body 33, and a bent pipe 10 sealed and rotatably connected to the fixed pipe 9. The bent pipe 10 is sealed and slidably engaged with the condensation pipe 3, and is also connected to a mixing structure arranged on the condensation pipe 3. A vent 3301 is provided on the box body 33.

[0037] When the first driving motor 6 drives the condensing pipe 3 to swing back and forth, the elbow 10 swings along with the condensing pipe 3. During this process, the elbow 10 slides back and forth on the condensing pipe 3. At this time, the elbow 10 triggers the mixing structure, which can mix the refrigerant medium in the cold box 2 and improve the uniformity of the refrigeration temperature distribution in the cold box 2. In addition, when the condensing pipe 3 reciprocates and deflects, the curved pipe 10 drives the cross plate 8 to slide reciprocatingly in the guide groove 201 accordingly. Taking the state shown in the accompanying drawing as an example, the cross plate 8 is located in the middle part of the guide groove 201. At this time, a section is left empty at both ends of the guide groove 201. The cross plate 8 can ensure that the side plate of the cold box 2 is isolated from the outside during the reciprocating sliding process, thereby ensuring smooth and stable oil and gas transmission.

[0038] The mixing structure includes a sleeve 11 rotatably mounted on the condensation pipe 3 and a stirring paddle arranged on the outer wall of the sleeve 11. The outer periphery of the sleeve 11 is also slidably sleeved with a ring body 13, and the ring body 13 is connected to the elbow 10 through two connecting arms 12. A convex column 1301 is arranged on the inner wall of the ring body 13, and a sliding groove 1101 adapted to the convex column 1301 is arranged on the sleeve 11. The sliding groove 1101 is spirally arranged, and the convex column 1301 extends into the sliding groove 1101 and is slidably connected to the sleeve 11.

[0039] When the condensing pipe 3 reciprocates, the curved pipe 10 drives the cross plate 8 to slide reciprocatingly in the guide groove 201, so that the height of the upper end of the curved pipe 10 remains unchanged, and the curved pipe 10 will slide reciprocatingly on the condensing pipe 3 during the deflection process, and the ring body 13 drives the boss 1301 to reciprocate along the axial direction of the sleeve 11, and the boss 1301 slides with the sleeve 11 through the slide groove 1101. Since the slide groove 1101 is spirally arranged, the sleeve 11 will rotate. In addition to the mixing effect on the refrigerant medium when the condensing pipe 3 reciprocates, the rotation of the stirring paddle on the outer wall of the sleeve 11 can enhance the mixing effect, and further improve the uniformity of the distribution of the refrigeration temperature in the cold box 2.

[0040] Please refer again Figure 1 , Fig. 9 as well as Fig.10 The drainage mechanism includes a transition chamber 14 disposed at the bottom of the cold box 2, and a set 7 disposed in the cold box 2 and sealed and rotatably connected to the straight section 301, wherein the set 7 is hollow inside and connected to the transition chamber 14 through a conduit; Among them, the inner wall of the kit 7 is provided with a plurality of strip-shaped openings 701 at equal intervals along the circumference, the straight section 301 is provided with a plurality of arc-shaped openings 302, the transition bin 14 and the storage tank 18 are respectively connected with a first vertical pipe 16 and a second vertical pipe 17, and a temporary storage device 15 is connected between the first vertical pipe 16 and the second vertical pipe 17.

[0041] During operation, when the condensation pipe 3 reciprocates and deflects, the liquid inside it will flow into the temporary storage 15 through the arc-shaped opening 302, the strip-shaped opening 701 and the first vertical pipe 16. At this time, the isolation control mechanism connects the first vertical pipe 16 and blocks the second vertical pipe 17, thereby avoiding branching of the oil and gas flow route in the condensation pipe 3, resulting in oil and gas waste; Subsequently, the isolation control mechanism can first block the first vertical pipe 16 and then open the second vertical pipe 17 , so that the liquid in the temporary storage device 15 can enter the storage tank 18 through the second vertical pipe 17 for storage.

[0042] The partition control mechanism includes a first control component and a second control component which are respectively arranged on the first vertical pipe 16 and the second vertical pipe 17 and have the same structure. The first control component and the second control component cooperate with a threaded drive structure installed on the frame 1.

[0043] It should be noted that the first control component and the second control component have the same structure, and therefore, a specific description will be given to the first control component. The first control assembly includes a movable sleeve 20 slidably sleeved on the first vertical tube 16, a conical member 21 located inside the first vertical tube 16 and connected to the movable sleeve 20 through two connecting columns, an annular protrusion 22 is provided on the inner wall of the first vertical tube 16, and a conical surface 2201 adapted to the conical member 21 is formed on the annular protrusion 22; The outer periphery of the first vertical tube 16 is formed with an annular portion 1601 , and is also sleeved with a cylindrical spring 19 . The cylindrical spring 19 is located between the annular portion 1601 and the movable sleeve 20 , and the two ends of the cylindrical spring 19 are respectively connected to the annular portion 1601 and the movable sleeve 20 .

[0044] Further, taking the state shown in the accompanying drawings as an example, at this time, the first vertical pipe 16 is in a conducting state, the conical member 21 is not in contact with the conical surface 2201, and in the second vertical pipe 17, the conical member 21 is in contact with the conical surface 2201, so the liquid in the condensation pipe 3 can flow into the temporary storage device 15 for temporary storage.

[0045] The two movable sleeves 20 located on the first vertical tube 16 and the second vertical tube 17 are respectively connected to the first driven plate 23 and the second driven plate 34. The first driven plate 23 and the second driven plate 34 are evenly spaced and provided with a plurality of trapezoidal protrusions. The length of the trapezoidal protrusions on the first driven plate 23 is greater than the length of the trapezoidal protrusions on the second driven plate 34. The first driven plate 23 and the second driven plate 34 also cooperate with the transverse driving assembly provided on the frame 1.

[0046] The transverse driving assembly includes a guide plate 28 provided on the frame 1, a slider 26 slidably engaged with the guide plate 28, and a fixed arm 27 fixedly mounted on the slider 26, wherein the slider 26 is connected to a threaded driving member provided on the frame 1. Two driving columns 2701 are provided on the fixed arm 27, and the two driving columns 2701 cooperate with the first driven plate 23 and the second driven plate 34 respectively.

[0047] Specifically, the threaded driving member rotates a screw rod 25 mounted on the frame body 1 and a second driving motor 24 mounted on the frame body 1, the screw rod 25 is connected to the output end of the second driving motor 24, and the screw rod 25 passes through the slider 26, and the slider 26 is threadedly connected to the screw rod 25; During operation, the second driving motor 24 drives the screw rod 25 to rotate. Under the guiding action of the guide plate 28, the slider 26 is threadedly matched with the screw rod 25 and slides along the length direction of the guide plate 28. Correspondingly, since the length of the trapezoidal protrusion on the first driven plate 23 is greater than the length of the trapezoidal protrusion on the second driven plate 34, the driving column 2701 located at the top first contacts the inclined surface of the trapezoidal protrusion on the first driven plate 23, causing the first driven plate 23 to give way, and the first driven plate 23 drives the movable sleeve 20 on the first vertical pipe 16 to slide upward, the column spring 19 is compressed, and the first vertical pipe 16 is blocked. Subsequently, the driving column 2701 located at the bottom contacts the inclined surface of the trapezoidal protrusion on the second driven plate 34, prompting the second driven plate 34 to drive the movable sleeve 20 on the second vertical pipe 17 to slide downward, the second vertical pipe 17 is connected, and the liquid in the temporary storage 15 can flow into the storage tank 18.

[0048] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
