Description

Technical Field

[0001] This utility model relates to the field of separation tank technology, and in particular to gas-liquid separation tank. Background Technology

[0002] Gas-liquid separators are key equipment in many fields such as petrochemicals, environmental protection, and refrigeration and air conditioning. Their core function is to achieve efficient separation of gas and liquid, ensuring stable system operation. In the petroleum refining process, gas-liquid separators can effectively separate oil and gas, improving product quality; in refrigeration systems, they can separate the gas and liquid phases of the refrigerant, ensuring the normal operation of the compressor. With the continuous expansion of industrial production scale and increasingly stringent process requirements, higher standards are being placed on the performance, reliability, and ease of maintenance of gas-liquid separators.

[0003] Existing gas-liquid separators typically employ fixed installation for key internal components. For example, the demister mesh, a crucial component for improving separation efficiency, is usually fixed inside the tank via welding or bolting. Its technical principle primarily utilizes the fine mesh structure to intercept tiny liquid droplets carried in the gas, achieving gas-liquid separation through droplet aggregation on the mesh surface and gravity. Regarding the exhaust structure, traditional gas-liquid separators often use simple pipe connections for natural gas outlets, relying solely on pressure differences from downstream equipment to maintain unidirectional gas flow, lacking an effective backflow prevention mechanism.

[0004] However, this traditional structural design has significant drawbacks. While welding or bolting ensures the stability of the demister installation, maintenance and cleaning require various tools such as wrenches and cutting equipment, making the disassembly process cumbersome, complex, and time-consuming. Especially in continuous industrial production scenarios, prolonged disassembly and maintenance can extend equipment downtime, severely impacting production efficiency. Furthermore, frequent tool handling and disassembly can damage the tank and the demister itself, further increasing maintenance costs and the risk of equipment failure. Therefore, a gas-liquid separator is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a gas-liquid separator, which aims to improve the problem that the existing technology requires more tools and takes longer to disassemble and assemble the defoaming screen.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gas-liquid separator includes a separator, an inlet pipe fixedly connected to the outer wall of the separator, a support rod fixedly connected to the outer wall of the separator, a baffle fixedly connected to the inside of the separator, an umbrella plate fixedly connected to the inside of the separator, a sealed cover fixedly connected to the top of the separator, a defoaming screen slidably connected to the inside of the separator, a disassembly and assembly assembly provided inside the defoaming screen, an exhaust pipe fixedly connected to the outer wall of the sealed cover, a limiting assembly provided inside the exhaust pipe, and a drain pipe fixedly connected to the bottom of the separator.

[0008] The disassembly and assembly assembly includes a card plate and a card slot opened inside the separation tank. The outer wall of the card plate is slidably connected to the inside of the card slot. A limit plate is slidably connected inside the defoaming screen. The outer wall of the limit plate is fixedly connected to the outer wall of the card plate. A connecting column is fixedly connected to the other side of the limit plate. A pull ring is rotatably connected to the outer wall of the connecting column. A reset assembly is provided on the outer wall of the connecting column.

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

[0010] The reset assembly includes a spring, the inner wall of which is sleeved on the outer wall of the connecting column. One end of the connecting column is fixedly connected to the outer wall of the limiting plate, and the other end of the connecting column is fixedly connected to the inner wall of the foam breaking mesh.

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

[0012] The limiting component includes a sealing plug, the outer wall of which is slidably connected to the interior of the exhaust pipe.

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

[0014] An exhaust port is provided inside the exhaust pipe, and the outer wall of the sealing plug is slidably connected to the inside of the exhaust port.

[0015] As a further description of the above technical solution:

[0016] A sealing plate is fixedly connected to the outer wall of the sealing plug, and a sliding column is fixedly connected to the other side of the sealing plate.

[0017] As a further description of the above technical solution:

[0018] A connecting rod is fixedly connected inside the exhaust pipe, and a fixed outer shell is fixedly connected to one end of the connecting rod.

[0019] As a further description of the above technical solution:

[0020] The other end of the sliding column is fixedly connected to a sliding plate, and the outer wall of the sliding plate is slidably connected inside the fixed outer shell.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the card plate moves by pulling the pull ring. When the pull ring is pulled, the pull ring drives the sliding column and the limiting plate, and in conjunction with the spring, the card plate slides inside the slot, thus facilitating the disassembly and assembly of the foam breaking screen. This makes it convenient to maintain or clean the screen, solving the problem that traditional disassembly and assembly requires many tools and takes a long time, and improving the convenience of disassembly and assembly of the foam breaking screen.

[0025] 2. In this utility model, the sealing plug achieves its movement function through the discharge of gas. When the gas is discharged, the sealing plate and sliding column are driven by the gas and cooperate with the second spring to realize the sliding of the sealing plug inside the exhaust port. This can effectively prevent gas backflow to ensure separation efficiency, enhance system safety, optimize operating economy, and has a wide range of applications. It solves the problems of gas backflow, system overpressure, and medium backflow contamination, and improves separation efficiency, system safety, and operating economy. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a gas-liquid separator, comprising a separator 1. The separator 1 is a cylindrical tank structure, welded from high-strength carbon steel, capable of withstanding internal pressure to ensure safe and stable operation. An inlet pipe 4 is fixedly connected to the outer wall of the separator 1, and a support rod 5 is also fixedly connected to the outer wall. The support rod 5 consists of three symmetrically distributed angle steels, with an anti-slip rubber pad at the bottom to support the separator 1, ensuring its stability during operation and preventing displacement due to vibration. A baffle 9 is fixedly connected inside the separator 1. The baffle 9 is an arc-shaped steel plate structure used to change the flow direction of the gas-liquid mixture, promoting initial gas-liquid separation and reducing the impact of liquid on subsequent... To prevent the impact of the separation components, an umbrella plate 7 is fixedly connected inside the separation tank 1. The umbrella plate 7 is made of stainless steel sheet and is inverted umbrella-shaped structure. It is used to intercept and separate larger liquid droplets carried in the gas, thereby improving the gas-liquid separation efficiency. A sealing cover 3 is fixedly connected to the top of the separation tank 1. A defoaming net 8 is slidably connected inside the separation tank 1. The defoaming net 8 is woven from multiple layers of stainless steel wire mesh with fine mesh holes. It is used to perform secondary fine filtration of the gas, intercept tiny liquid droplets, and ensure the purity of the discharged gas. A disassembly and assembly component is set inside the defoaming net 8. An exhaust pipe 2 is fixedly connected to the outer wall of the sealing cover 3. A limiting component is set inside the exhaust pipe 2. A drain pipe 6 is fixedly connected to the bottom of the separation tank 1.

[0035] The assembly and disassembly components include a clamping plate 15 and a slot 14 formed inside the separation tank 1. The outer wall of the clamping plate 15 is slidably connected to the inside of the slot 14. The clamping plate 15 is a metal plate structure, and its outer wall is slidably connected to the inside of the slot 14 to fix the defoaming screen 8 and prevent it from shaking inside the separation tank 1. A limiting plate 13 is slidably connected inside the defoaming screen 8. The outer wall of the limiting plate 13 is fixedly connected to the outer wall of the clamping plate 15. A connecting post 11 is fixedly connected to the other side of the limiting plate 13. A pull ring 10 is rotatably connected to the outer wall of the connecting post 11. The pull ring 10 is used to facilitate the operator to pull the connecting post 11, thereby driving the clamping plate 15 to move. A reset component is provided on the outer wall of the connecting post 11. The reset component includes a spring 12. The inner wall of the spring 12 is sleeved on the outer wall of the connecting post 11. One end of the connecting post 11 is fixedly connected to the outer wall of the limiting plate 13, and the other end of the connecting post 11 is fixedly connected to the inner wall of the defoaming screen 8.

[0036] Specifically, in the gas-liquid separation process, the efficient separation of the gas-liquid mixture is crucial. The specific process is as follows: the material is first transported into the separation tank 1 through the feed pipe 4. After feeding, the baffle 9 plays a key role, effectively changing the flow direction of the gas-liquid mixture and ensuring that the mixture is evenly dispersed within the separation tank 1, preventing excessively high local flow velocities from affecting the separation effect. Subsequently, the gas comes into contact with the umbrella plate 7 during its ascent. The umbrella plate 7 uses inertia and gravity to separate larger-diameter liquid droplets from the gas, achieving preliminary filtration. After the preliminary separation by the umbrella plate 7, the gas continues to rise and undergoes secondary fine filtration through the defoaming screen 8. The filter, the defoaming screen 8, is made of finely woven metal wire mesh, which can capture even smaller droplets, preventing them from being discharged with the gas and ensuring the purity of the emitted gas. The fully separated gas is discharged through the exhaust pipe 2, while the separated liquid is discharged in an orderly manner through the drain pipe 6. However, as operating time increases, the defoaming screen 8 will gradually become clogged due to trapping a large number of droplets, affecting separation efficiency. At this point, the operator only needs to pull the pull ring 10, which will cause the connecting column 11 to slide within the preset channel of the defoaming screen 8. The connecting column 11 further moves the limiting plate 13, compressing the spring 12 in the process. The movement of the limiting plate 13 will pull the clamping plate 15 out of the clamping slot 14, thus quickly removing the defoaming screen 8 for maintenance or replacement, shortening the replacement time of the defoaming screen 8, significantly reducing equipment downtime, and ensuring efficient and continuous gas-liquid separation.

[0037] Reference Figure 1 , Figure 4 and Figure 5The limiting component includes a sealing plug 20, which is a frustoconical structure made of highly corrosion-resistant stainless steel. Its outer wall is precisely fitted with the inside of the exhaust pipe 2, allowing it to slide smoothly inside the exhaust pipe 2. It is used to seal the exhaust port 19 and prevent gas backflow. The outer wall of the sealing plug 20 is slidably connected to the inside of the exhaust pipe 2. The exhaust pipe 2 has an exhaust port 19 inside, which is circular. Its diameter is designed according to the exhaust volume of the gas-liquid separator 1 and is used to discharge the separated gas. The outer wall of the sealing plug 20 is slidably connected to the inside of the exhaust port 19. When gas needs to be discharged, the sealing plug 20 can leave the exhaust port 19 under the action of gas pressure, allowing the gas to pass smoothly. The outer wall of the sealing plug 20 is slidably connected to the inside of the exhaust port 19. A sealing plate 21 is fixedly connected to the outer wall of the sealing plug 20. A sliding column 18 is fixedly connected to the other side of the sealing plate 21. A connecting rod 17 is fixedly connected to the inside of the exhaust pipe 2. A fixed housing 16 is fixedly connected to one end of the connecting rod 17. A sliding plate 23 is fixedly connected to the other end of the sliding column 18. The outer wall of the sliding plate 23 is slidably connected to the inside of the fixed housing 16. A second spring 22 is provided inside the fixed housing 16. One end of the second spring 22 is fixedly connected to the outer wall of the sliding plate 23, and the other end of the second spring 22 is fixedly connected to the inside of the fixed housing 16.

[0038] Specifically, during the gas discharge process of the gas-liquid separator 1, the exhaust port 19 serves as a key channel for gas discharge. Its internal unidirectional flow structure plays a crucial role. When the separated gas needs to be discharged, it enters through the exhaust port 19 and pushes the sealing plug 20 to slide within the exhaust port 19 by its own pressure. The movement of the sealing plug 20 causes the connected sealing plate 21 to slide synchronously, thereby driving the sliding column 18 to move. The movement of the sliding column 18 causes the sliding plate 23 to slide inside the fixed outer shell 16. During this process, the second spring 22 is compressed, making the exhaust channel unobstructed and allowing the gas to be discharged smoothly. When the gas discharge ends and the system pressure decreases, the second spring 22 rebounds due to its elasticity, causing the sealing plug 20 to quickly return to its initial position, accurately closing the exhaust port 19. This effectively prevents gas backflow and prevents liquid or impurities in downstream equipment from flowing back into the separator 1, ensuring the stability and efficiency of the gas-liquid separation operation.

[0039] Working principle: During gas-liquid separation, gas is fed into the separator 1 through the feed pipe 4. The gas is blocked by the baffle 9 and then filtered by the umbrella plate 7 to remove liquid droplets. The gas is then filtered again by the defoaming screen 8 to prevent contamination. The gas is then discharged through the exhaust pipe 2 and the liquid is discharged through the drain pipe 6. If the filtration time is too long, the pull ring 10 can be pulled. The pull ring 10 drives the connecting column 11 to slide inside the defoaming screen 8. The connecting column 11 then drives the limiting plate 13 to slide inside the defoaming screen 8, compressing the spring 12. The limiting plate 13 then drives the locking plate 15 to slide from the locking groove 14, making it easy to remove the defoaming screen 8 for maintenance or replacement, reducing downtime.

[0040] In addition, when the gas is discharged, it flows through the exhaust port 19, and then the sealing plug 20 slides from inside the exhaust port 19. Then the sealing plug 20 drives the sealing plate 21 to slide, and then the sealing plate 21 drives the sliding column 18 to move, causing the sliding plate 23 to slide inside the fixed housing 16, compressing the second spring 22, thereby allowing the gas to flow. When the discharge ends, the second spring 22 rebounds and drives the sealing plug 20 back to its original position, closing the exhaust port 19 and preventing gas backflow.

[0041] 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.
