Description

Technical Field

[0001] This utility model relates to the field of oil-gas separation technology, and in particular to a novel oil-gas separator cooling device. Background Technology

[0002] In industries such as petrochemicals, natural gas extraction, and storage, oil-gas separators are key equipment for achieving efficient oil-gas separation. During the oil-gas separation process, the equipment generates a significant amount of heat. If this heat is not effectively cooled in a timely manner, it will not only reduce separation efficiency but may also affect the safety and lifespan of the equipment. Therefore, oil-gas separator cooling devices are indispensable supporting facilities for ensuring the stable operation of oil-gas separation systems. These devices remove the heat generated by the oil-gas separator through cooling circulation, maintaining the equipment within a suitable temperature range and ensuring efficient and safe oil-gas separation operations.

[0003] Most commercially available oil-gas separator cooling devices employ traditional cooling structures and control methods. On the one hand, these devices often lack effective impurity filtration mechanisms. Impurities carried by the hot fluid during circulation can easily enter the pipes and equipment, causing pipe blockages and component wear, thereby reducing heat exchange efficiency, increasing equipment maintenance costs and downtime for repairs, and seriously affecting production continuity. Therefore, a new type of oil-gas separator cooling device is proposed. Summary of the Invention

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel oil-gas separator cooling device, comprising a base plate, wherein a shell, a circulating pump, and an oil-gas separator are sequentially installed on the top of the base plate from right to left; a water pump is fixedly connected to the front side of the top of the base plate; a water storage tank is fixedly connected to the rear side of the top of the base plate; a cold flow inlet and a hot flow inlet are fixedly connected to the top of the outer wall of the shell; a cold flow outlet and a hot flow outlet are fixedly connected to the bottom of the outer wall of the shell; a partition is fixedly connected to the left side of the interior of the shell; a cooling pipe is installed on the right side of the interior of the shell; a filter screen is installed on the inner wall of the hot flow inlet; a fixing component is provided inside the hot flow inlet; a return pipe is installed at the bottom of the cold flow outlet; an adjustment component is provided on the outer wall of the return pipe; and a heat spreader is fixedly connected to the top edge of the base plate.

[0006] The fixing assembly includes two actuating plates, the outer walls of which are slidably connected to the inner wall of the hot flow inlet. A rope is fixedly connected to the side of each actuating plate that is far apart from the actuating plate. A limit plate is fixedly connected to the end of the rope that is far away from the actuating plate. A locking rod is fixedly connected to the side of the limit plate that is far away from the rope. A spring is sleeved on the outer wall of the rope.

[0008] The regulating assembly includes a housing, which is fixedly connected to the outer wall of the return pipe. A thermostat is fixedly connected inside the housing. A connecting rod is fixedly connected to the outer wall of the thermostat. A baffle is fixedly connected to the side of the connecting rod away from the thermostat. A spring is sleeved on the outer wall of the connecting rod. A return pipe is fixedly connected to the bottom of the outer wall of the housing. A return pipe is fixedly connected to the rear side of the outer wall of the housing.

[0009] As a further description of the above technical solution:

[0010] The inner wall of the hot flow inlet is provided with a groove, and the outer wall of the actuating plate is fixedly connected to a slider, the outer wall of the slider being slidably connected to the inner wall of the groove.

[0011] As a further description of the above technical solution:

[0012] A pipe is installed between the input end of the circulating pump and the hot flow discharge port, and a pipe is installed between the output end of the circulating pump and the oil-gas separator.

[0013] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the filter screen effectively intercepts impurities in the hot fluid, preventing them from clogging pipes and wearing down parts. Simultaneously, with the fixing components, when the filter screen needs cleaning or maintenance, the operator only needs to move the actuating plate, which, via ropes and a limiting plate, drives the locking rod to disengage from the filter screen for quick removal. After cleaning, a spring automatically drives the locking rod to reset and engage, enabling convenient filter screen installation, greatly reducing maintenance difficulty and time costs, and ensuring the continuous and stable operation of the device.

[0023] 2. In this utility model, the thermostat in the regulating component can monitor the cooling fluid temperature in real time and automatically adjust the cold fluid return path according to temperature changes. When the coolant temperature is higher than the set threshold, the thermostat pushes the baffle to block the return pipe three, causing the coolant to flow back to the water tank through the return pipe two. During this process, the heat exchange plate further cools the coolant, ensuring that the coolant re-entering the circulation has a good cooling effect. When the temperature is low, the coolant returns through the return pipe three, reducing unnecessary cooling energy consumption. Attached Figure Description

A cold flow outlet 8 and a hot flow outlet 10 are fixedly connected to the bottom of the outer wall of the shell 2, used for the discharge of the cooled fluid. The discharge and cooling of the hot fluid are achieved through the following process: A partition 11 is fixedly connected to the left side of the shell 2, which divides the interior of the shell 2 into different areas, optimizes the heat exchange path, and improves the heat exchange efficiency. A cooling pipe 12 is installed on the right side of the shell 2, which is used to exchange heat with the hot fluid and reduce the temperature of the hot fluid. A filter screen 18 is installed on the inner wall of the hot fluid inlet 9, which can filter impurities in the hot fluid and prevent impurities from entering the device and affecting the heat exchange effect and equipment operation.

[0033] Reference Figures 2-4The fixing assembly includes two actuating plates 13. The outer wall of the actuating plates 13 is slidably connected to the inner wall of the hot flow inlet 9. The actuating plates 13 are the main structural components of the entire fixing assembly. By actuating the actuating plates 13, the ropes 14, limiting plates 15 and locking rods 16 connected to them can be moved. The two actuating plates 13 are fixedly connected to the opposite sides of each other. The ropes 14 are used to transmit the movement of the actuating plates 13. The end of the rope 14 away from the actuating plates 13 is fixedly connected to the limiting plate 15. The limiting plate 15 restricts the range of movement of the locking rod 16 and prevents the locking rod 16 from moving excessively and leaving the predetermined position. The locking rod 16 is fixedly connected to the side of the limiting plate 15 away from the rope 14. The locking rod 16 engages with the filter screen 18 to achieve the effect of fixing the filter screen 18. A spring 17 is sleeved on the outer wall of the rope 14.

A thermostat 25 is fixedly connected inside the housing 22. As the core component of the regulating assembly, the thermostat 25 automatically responds to changes in the temperature of the cold fluid passing through the return pipe 21. A connecting rod 26 is fixedly connected to the outer wall of the thermostat 25. A baffle 27 is fixedly connected to the side of the connecting rod 26 away from the thermostat 25. The thermostat 25 is connected to the baffle 27 via the connecting rod 26. When the thermostat 25 detects a change in the cold fluid temperature, it moves the connecting rod 26, thereby causing the baffle 27 to move. 7. Move to change the relative position between the baffle 27 and the return pipe 23 and the return pipe 24, so as to adjust the return path and flow rate of the cold fluid. The outer wall of the connecting rod 26 is fitted with a spring 28. When the thermostat 25 is not activated, the spring 28 provides a preload force to the baffle 27 to keep the baffle 27 in the initial position. The bottom of the outer wall of the outer shell 22 is fixedly connected to the return pipe 23, and the rear side of the outer wall of the outer shell 22 is fixedly connected to the return pipe 24. The return pipe 23 and the return pipe 24 are respectively fixedly connected to the bottom and rear side of the outer wall of the outer shell 22 to guide the cold fluid in different states back to the water storage tank 5.

[0035] Reference Figure 4 The inner wall of the hot flow inlet 9 is provided with a groove 19, and the outer wall of the actuating plate 13 is fixedly connected with a slider 20. The outer wall of the slider 20 is slidably connected to the inner wall of the groove 19. The groove 19 and the slider 20 cooperate to restrict the movement direction of the actuating plate 13, ensuring that the actuating plate 13 will not deviate or shake during the movement, thereby ensuring that the fixing component can accurately and stably realize the fixing and disassembly operation of the filter screen 18.

[0036] Reference Figure 1 and Figure 2A pipe is installed between the input end of the circulating pump 3 and the hot flow discharge port 10, and a pipe is installed between the output end of the circulating pump 3 and the oil-gas separator 4. The pipe between the input end of the circulating pump 3 and the hot flow discharge port 10 is used to transport the hot fluid after being cooled by the shell 2 to the circulating pump 3; the pipe between the output end of the circulating pump 3 and the oil-gas separator 4 is used to transport the hot fluid pressurized by the circulating pump 3 back to the oil-gas separator 4.

[0037] Reference Figure 1 and Figure 2 A pipe is installed between the input end of the water pump 6 and the water storage tank 5, and a pipe is connected between the output end of the water pump 6 and the cold flow inlet 7. The pipe between the water pump 6 and the water storage tank 5 is used to draw coolant from the water storage tank 5; the pipe between the water pump 6 and the cold flow inlet 7 is used to transport the coolant pressurized by the water pump 6 to the cold flow inlet 7 inside the housing 2, so that the coolant enters the housing 2 and exchanges heat with the hot fluid.

[0038] Reference Figure 1 , Figure 2 and Figure 5 The end of the return pipe 24 away from the outer casing 22 is installed inside the water storage tank 5, and the end of the return pipe 23 away from the outer casing 22 is installed inside the water storage tank 5. The return pipe 23 and the return pipe 24 are used to return the cold fluid after being regulated by the regulating component to the water storage tank 5, so as to realize the recycling of the coolant.

[0039] Reference Figure 4 The clamping rod 16 passes through the hot flow inlet 9 and engages with the filter screen 18. The engagement secures the filter screen 18 and prevents it from shifting or loosening when the hot fluid passes through the hot flow inlet 9. A sealing ring is provided on the outer wall of the filter screen 18. The sealing ring can form a sealing structure between the filter screen 18 and the hot flow inlet 9 to prevent the hot fluid from leaking from the connection between the filter screen 18 and the hot flow inlet 9.

[0040] Reference Figure 1 The outer wall of the return pipe 23 is fitted inside the heat spreader 29, so that the cold fluid returning from the return pipe 23 can exchange heat with the heat spreader 29 during the flow process.

[0041] Working principle: When oil and gas separation is required, firstly, the oil and gas are transported from the external pipeline to the inside of the shell 2 through the hot flow inlet 9. Then, the water pump 6 is powered on and started. After the water pump 6 starts, it will transport the coolant in the water tank 5 to the inside of the shell 2 through the cold flow inlet 7. After the liquid oil enters the inside of the shell 2, it will flow under the action of the cooling pipe 12 and be discharged through the hot flow outlet 10. During the flow, the inside of the shell 2 will be filled with a large amount of coolant through the cold flow inlet 7 to cool and lower the temperature of the cooling pipe 12. Then, it will be pumped by the circulating pump 3 and transported to the inside of the oil-gas separator 4. The oil and gas are separated by the oil-gas separator 4. Finally, the separated liquid oil in the oil-gas separator 4 is transferred by external equipment.

[0042] When the liquid oil enters the hot feed inlet 9, it first passes through the filter screen 18 inside the hot feed inlet 9 to filter impurities. When the hot feed inlet 9 becomes clogged after long-term use, the two actuating plates 13 are pushed. When the actuating plates 13 are pushed, the rope 14 will slide, and the rope 14 will drive the limiting plate 15 to slide, thereby driving the locking rod 16 to slide, so that the locking rod 16 is disengaged from the fixed state of the filter screen 18. Then, the filter screen 18 is taken out and cleaned. After cleaning, the filter screen 18 is put back into the cold feed inlet 7. Under the elastic force of the spring 17, the limiting plate 15 will slide, further driving the locking rod 16 to slide, so that the locking rod 16 is engaged with the filter screen 18, thus fixing the filter screen 18.

[0043] After cooling, the coolant is discharged through the cold flow discharge port 8 and the return pipe 21. When the coolant passes through the outer casing 22, the thermostat 25 inside the outer casing 22 will act accordingly according to the temperature of the coolant. When the temperature is higher than the melting point of the paraffin inside the thermostat 25, the paraffin will melt, which will push the connecting rod 26 and the baffle 27 to slide, so that the baffle 27 blocks the return pipe 24. At this time, the coolant can only flow back to the water tank 5 through the return pipe 23. During this process, the heat spreader 29 will further cool the coolant inside the return pipe 23. When the temperature is lower than the melting point, it will flow back to the water tank 5 through the return pipe 24.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
