Description

Technical Field

[0001] This invention relates to the field of oil and gas recovery technology, specifically a medium condensation oil and gas recovery device with switchable heat and cold tracing. Background Technology

[0002] Oil and gas recovery technology can effectively reduce emissions of volatile organic compounds (VOCs), a major source of air pollution. Through oil and gas recovery, the concentration of harmful substances in the air can be reduced, improving air quality and thus protecting the environment. Oil and gas recovery not only reduces waste but also converts the recovered oil and gas into liquefied gasoline, thereby conserving resources and improving energy efficiency.

[0003] Oil and gas condensation recovery is a method that uses refrigeration technology to transform light hydrocarbon components in oil and gas from the gas phase to the liquid phase, thereby realizing the resource recovery of oil and gas. However, the liquid droplets formed after the oil and gas are cooled are prone to wall adhesion, that is, they adhere to the inner wall of the pipeline and are difficult to slide down the pipe wall smoothly and be collected and recovered. If the wall adhesion persists for a long time, the droplets are prone to crystallization inside the pipe, which can reduce the oil and gas recovery rate or even cause pipeline blockage. Summary of the Invention

[0004] The purpose of this invention is to provide a medium condensate oil and gas recovery device that can switch between heat tracing and cooling, so as to solve the problems mentioned in the background art.

The bent pipe is sealed and slidably fitted with the condensation pipe and is also connected to a mixing structure disposed on the condensation pipe. The box body is provided with a vent.

[0015] As a further embodiment of the present invention: the mixing structure includes a sleeve rotatably mounted on the condensation pipe and a stirring paddle disposed on the outer wall of the sleeve, and an annular body is slidably fitted on the outer periphery of the sleeve, the annular body being connected to the bend pipe through two connecting arms;

[0016] The inner wall of the ring is provided with a protruding post, and the sleeve is provided with a sliding groove adapted to the protruding post. The sliding groove is spirally arranged, and the protruding post extends into the sliding groove and is slidably connected to the sleeve.

[0017] As a further embodiment of the present invention: the diversion mechanism includes a transition chamber disposed at the bottom of the cold storage box, and a kit disposed in the cold storage box and rotatably connected to the straight section in a sealed manner. The kit is hollow inside and is connected to the transition chamber through a conduit.

[0018] The inner wall of the kit is provided with multiple strip-shaped openings at equal intervals along the circumference, and the straight section is provided with multiple arc-shaped openings. The transition chamber and the storage tank are respectively connected by a first vertical pipe and a second vertical pipe, and a temporary storage device is connected between the first vertical pipe and the second vertical pipe.

[0019] As a further embodiment of the present invention: the partition control mechanism includes a first control component and a second control component that are respectively disposed on the first vertical pipe and the second vertical pipe and have the same structure, and the first control component and the second control component cooperate with a threaded drive structure installed on the frame.

[0020] As a further embodiment of the present invention: the first control component includes a movable sleeve that is slidably sleeved on the first vertical tube, a conical member located inside the first vertical tube and connected to the movable sleeve through two connecting posts, and an circumferential protrusion provided on the inner wall of the first vertical tube, wherein a conical surface adapted to the conical member is formed on the circumferential protrusion.

[0021] The first vertical tube has an annular portion on its outer periphery and is fitted with a cylindrical spring. The cylindrical spring is located between the annular portion and the movable sleeve, and its two ends are respectively connected to the annular portion and the movable sleeve.

[0022] As a further embodiment of the present invention: the two movable sleeves located on the first vertical tube and the second vertical tube are respectively connected to a first driven plate and a second driven plate.

[0024] The fixed arm is provided with two drive columns, which respectively cooperate with the first driven plate and the second driven plate.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] Multiple condenser pipes can reciprocate synchronously within the cooling chamber. This serves two purposes: firstly, it mixes the refrigerant in the cooling chamber, improving the uniformity of the cooling temperature distribution; secondly, the reciprocating motion of the condenser pipes causes the droplets adhering to their inner walls to experience centrifugal force, promoting droplet aggregation. When the accumulated droplets reach a certain level, they slide out of the condenser pipes under gravity, improving the efficiency of condensate removal. Furthermore, it avoids crystallization caused by droplets adhering to the inner walls of the condenser pipes for extended periods, which could lead to reduced oil and gas recovery or, in severe cases, blockage.

[0027] Secondly, the condensed medium is collected in the storage tank. When it is pumped out, the required temperature varies depending on the medium, so it needs to be kept cold or hot. Electric heating tape is spirally wrapped around the oil pipeline to raise and control the temperature, while cooling corrugated pipe is spirally wrapped around the oil pipeline to lower and control the temperature, achieving the required temperature for the oil pipeline. This prevents the medium from crystallizing and clogging the pipeline, avoiding the need for extensive manpower to clean blockages, which can severely damage electrical instruments and the oil pump motor, affecting the normal operation of the equipment.

[0028] In addition, an isolation control mechanism is set up to switch the conduction and blocking states of the first and second vertical pipes during the processing, so as to achieve effective recovery of condensate. During the recovery, the recovery path can be isolated to prevent oil and gas leakage and waste. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Furthermore, elements in this invention are referred to as being "disposed on" or "located on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0042] Please see Figures 1-10 In this embodiment of the invention, a medium condensate oil and gas recovery device with switchable heat tracing and cooling includes a frame 1 and a cooling tank 2 installed on the frame 1, and further includes:

[0043] The condensing pipes 3 are arranged in a serpentine shape, and multiple condensing pipes 3 are arranged at equal intervals in the cooling box 2. The multiple condensing pipes 3 can swing synchronously, and each end of the condensing pipe 3 is connected to a set of oil and gas transmission mechanisms.

[0044] Storage tank 18 is installed on the frame 1 and is used to store the liquid droplets generated by condensation. The storage tank 18 is connected to a dual-control pumping mechanism for cold and hot, which is used to pump out the medium in the storage tank 18.

[0045] An isolation control mechanism is provided on the storage tank 18 and connected to the condensation pipe 3 through a diversion mechanism to form a recovery path for droplets in the condensation pipe 3, and the isolation control mechanism can divide the recovery path into two sections.

[0046] Furthermore, during operation, the temperature in the cooling chamber 2 needs to be controlled in advance to ensure that the internal temperature of the cooling chamber 2 meets the requirements for oil and gas condensation.

[0047] Specifically, the oil and gas pass through the oil and gas passage mechanism and the condensation pipe 3. After heat exchange, the temperature of the oil and gas decreases in the condensation pipe 3, and it condenses into liquid. Liquid droplets are generated in the condensation pipe 3, and the liquid droplets can flow out from the condensation pipe 3 through the drainage mechanism.

[0048] When the isolation control mechanism is activated, it first blocks the upper section of the recovery passage to prevent oil and gas from entering the storage tank 18 to avoid losses. Then, the lower section of the recovery passage is opened, so the droplets located in the upper section can enter the storage tank 18 for storage.

[0049] When the hot and cold dual-control pumping mechanism is working, it pumps out the condensed products in the storage tank 18.

[0050] During the above process, multiple condensing pipes 3 can synchronously reciprocate within the cooling chamber 2. This serves two purposes: firstly, it mixes the refrigerant in the cooling chamber 2, improving the uniformity of the cooling temperature distribution; secondly, as the condensing pipes 3 reciprocate, the droplets adhering to their inner walls are subjected to centrifugal force, which promotes droplet aggregation. When the accumulated droplets reach a certain level, they easily slide out of the condensing pipes 3 under gravity, improving the efficiency of condensate removal. Furthermore, it avoids crystallization caused by droplets adhering to the inner walls of the condensing pipes 3 for extended periods, which could lead to reduced oil and gas recovery or, in severe cases, blockage of the condensing pipes 3.

[0051] Please refer to it again. Figure 7 The dual-control hot and cold 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, and the oil outlet is connected to an oil pipe. An electric heating cable 31 and a cooling corrugated pipe 32 are spirally wound on the oil pipe. The frame 1 is also equipped with a cooling pump 30. The inlet and outlet of the cooling pump 30 are respectively connected to the cooling box 2 and one end of the cooling corrugated pipe 32. The other end of the cooling corrugated pipe 32 is connected to the cooling box 2.

[0052] Furthermore, the condensed medium is collected in the storage tank 18. When it is output by the oil pump 29, the required temperature varies depending on the medium, necessitating either cold or heat preservation. The temperature of the pipeline is raised and controlled by spirally wrapping an electric heating tape 31 around the oil pipeline, and cooled and controlled by spirally wrapping a cooling corrugated pipe 32 around the oil pipeline, achieving the required temperature for the oil pipeline. This prevents the medium from crystallizing and clogging the pipeline, avoiding the need for extensive manpower for cleaning after blockage, and in severe cases, damage to electrical instruments and the oil pump motor, affecting the normal operation of the equipment.

[0053] Please refer to it again. Figure 6 and Figure 8 The cooling chamber 2 is equipped with multiple rotating shafts 4, which are arranged in pairs opposite each other. 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 drive motor 6 installed on the outer wall of the cooling chamber 2.

[0054] The two adjacent rotating shafts 4 are connected by a transmission belt 5. The condensation pipe 3 is provided with multiple straight sections 301. The straight sections 301 are connected to the diversion mechanism, and the central axis of the straight sections 301 and the rotating shafts 4 coincide.

[0055] During the condensation recovery process, the first drive motor 6 operates, which drives the condensation pipe 3 to reciprocate through the rotating shaft 4. Multiple condensation pipes 3 achieve synchronous oscillation under the action of the transmission belt 5. Therefore, under the action of centrifugal force, it is beneficial for the accumulation of droplets adhering to the inner wall of the condensation pipe 3, thereby improving the discharge efficiency of condensate. In addition, it can also avoid the problem of crystallization caused by droplets adhering to the inner wall of the condensation pipe 3 for a long time. This can lead to a decrease in oil and gas recovery rate or even blockage of the condensation pipe 3.

[0056] Please refer to it again. Figure 4 , Figure 5 as well as Figure 8 The side plate of the cooling box 2 is provided with a guide groove 201. A horizontal plate 8 adapted to the guide groove 201 is sealed and slidably fitted inside the guide groove 201. The length of the guide groove 201 is greater than the length of the horizontal plate 8. The oil and gas transmission mechanism includes a box body 33 provided on the side of the cooling box 2, a plurality of fixed pipes 9 provided on the horizontal plate 8 and extending into the box body 33, and a bent pipe 10 sealed and rotatably connected to the fixed pipes 9. The bent pipe 10 is sealed and slidably fitted with the condensation pipe 3 and is also connected to a mixing structure provided on the condensation pipe 3. The box body 33 is provided with a vent 3301.

[0057] When the first drive motor 6 drives the condenser pipe 3 to swing back and forth, the bend 10 swings along with the condenser pipe 3. During this process, the bend 10 slides back and forth on the condenser pipe 3. At this time, the bend 10 will trigger the mixing structure. The mixing structure can mix the refrigerant in the cold storage box 2 and improve the uniformity of the refrigeration temperature distribution in the cold storage box 2.

[0058] Furthermore, when the condenser pipe 3 swings back and forth, the bend 10 drives the horizontal plate 8 to slide back and forth in the guide groove 201. Taking the state shown in the attached figure as an example, the horizontal plate 8 is located in the middle of the guide groove 201. At this time, a section is left empty at both ends of the guide groove 201. During the back and forth sliding process, the horizontal plate 8 can ensure that the side plate of the cold box 2 is isolated from the outside world, thereby ensuring the smooth and stable transmission of oil and gas.

[0059] The mixing structure includes a sleeve 11 rotatably mounted on the condenser pipe 3 and a stirring paddle disposed on the outer wall of the sleeve 11. An annular body 13 is slidably fitted around the outer periphery of the sleeve 11, and the annular body 13 is connected to the bend pipe 10 via two connecting arms 12. A protruding post 1301 is provided on the inner wall of the annular body 13, and a sliding groove 1101 adapted to the protruding post 1301 is provided on the sleeve 11. The sliding groove 1101 is spirally arranged, and the protruding post 1301 extends into the sliding groove 1101 and is slidably connected to the sleeve 11.

[0060] When the condensing pipe 3 swings back and forth, the bend 10 drives the horizontal plate 8 to slide back and forth in the guide groove 201. Thus, the height of the upper end of the bend 10 remains unchanged. During the swinging process, the bend 10 will slide back and forth on the condensing pipe 3. The ring 13 drives the protrusion 1301 to move back and forth along the axial direction of the sleeve 11. The protrusion 1301 slides with the sleeve 11 through the sliding groove 1101. Since the sliding groove 1101 is spirally arranged, the sleeve 11 will rotate. In addition to the mixing effect of the condensing pipe 3 on the refrigerant during the swinging back and forth, 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 refrigeration temperature distribution in the cooling box 2.

[0061] Please refer to it again. Figure 1 , Figure 9 as well as Figure 10 The drainage mechanism includes a transition chamber 14 disposed at the bottom of the cold storage box 2 and a kit 7 disposed in the cold storage box 2 and sealed and rotatably connected to the straight section 301. The kit 7 is hollow inside and is connected to the transition chamber 14 through a conduit.

[0062] The inner wall of the kit 7 is provided with multiple strip-shaped openings 701 at equal intervals along the circumference, and the straight section 301 is provided with multiple arc-shaped openings 302. The transition chamber 14 and the storage tank 18 are respectively connected by 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.

[0063] During operation, when the condensation pipe 3 reciprocates, the liquid inside it will flow through the arc-shaped port 302, the strip-shaped port 701 and the first vertical pipe 16 into the temporary storage device 15. At this time, the isolation control mechanism will open the first vertical pipe 16 and block the second vertical pipe 17, thereby preventing the oil and gas from branching in the flow path of the condensation pipe 3 and causing oil and gas waste.

[0064] 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 for storage through the second vertical pipe 17.

[0065] The partition control mechanism includes a first control component and a second control component that are respectively disposed 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.

[0066] It should be noted that the first control component and the second control component have the same structure. Therefore, the first control component will be described in detail.

[0067] The first control component includes a movable sleeve 20 that is slidably sleeved on the first vertical tube 16, and a tapered member 21 located inside the first vertical tube 16 and connected to the movable sleeve 20 through two connecting posts. The inner wall of the first vertical tube 16 is provided with an circumferential protrusion 22, and a tapered surface 2201 adapted to the tapered member 21 is formed on the circumferential protrusion 22.

[0068] The first vertical tube 16 has an annular portion 1601 formed on its outer periphery, and a cylindrical spring 19 is also sleeved thereon. The cylindrical spring 19 is located between the annular portion 1601 and the movable sleeve 20, and its two ends are respectively connected to the annular portion 1601 and the movable sleeve 20.

[0069] Furthermore, taking the attached diagram as an example, at this time, the first vertical pipe 16 is in a conductive 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. Therefore, the liquid in the condensation pipe 3 can flow into the temporary storage container 15 for temporary storage.

[0070] The two movable sleeves 20 located on the first vertical tube 16 and the second vertical tube 17 are respectively connected to a first driven plate 23 and a second driven plate 34. Both the first driven plate 23 and the second driven plate 34 are provided with multiple trapezoidal protrusions at equal intervals. 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 drive assembly provided on the frame 1.

[0071] The lateral movement drive assembly includes a guide plate 28 disposed on the frame 1, a slider 26 slidably fitted on the guide plate 28, and a fixed arm 27 fixedly mounted on the slider 26. The slider 26 is connected to a threaded drive component disposed on the frame 1. The fixed arm 27 is provided with two drive posts 2701, which respectively cooperate with the first driven plate 23 and the second driven plate 34.

[0072] Specifically, the threaded drive component is rotatably mounted on the frame 1 with a lead screw 25 and a second drive motor 24 mounted on the frame 1. The lead screw 25 is connected to the output end of the second drive motor 24, and the lead screw 25 passes through the slider 26. The slider 26 is threadedly connected to the lead screw 25.

[0073] During operation, the second drive motor 24 drives the lead screw 25 to rotate. Under the guidance of the guide plate 28, the slider 26 engages with the lead screw 25 and slides along the length 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 upper drive column 2701 first contacts the inclined surface of the trapezoidal protrusion on the first driven plate 23, causing the first driven plate 23 to give way. The first driven plate 23 drives the movable sleeve 20 on the first vertical tube 16 to slide upward, the column spring 19 is compressed, and the first vertical tube 16 is blocked. Subsequently, the lower drive column 2701 contacts the inclined surface of the trapezoidal protrusion on the second driven plate 34, causing the second driven plate 34 to drive the movable sleeve 20 on the second vertical tube 17 to slide downward, the second vertical tube 17 is opened, and the liquid in the temporary storage 15 can flow into the storage tank 18.

[0074] It will be apparent to those skilled in the art that the present 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 its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
