Description

Technical Field

[0001] This invention relates to the field of gas-liquid separation, and in particular to a high-efficiency gas-liquid separator. Background Technology

[0002] Gas-liquid separation technology is a common process in the production process of industries such as natural gas purification and petrochemicals. Gas-liquid separation technology can achieve the purpose of material recovery and purification of target substances. A gas-liquid separator is a device used in gas-liquid separation technology to separate liquid droplets or mist from gaseous fluids.

[0003] In related technologies, a gas-liquid separator includes a vertically arranged shell with an inlet. Inside the shell is a separation plate with through-holes. A gas-liquid mixture enters the shell through the inlet. Due to its weight, the liquid droplets sink downwards, while the gas moves upwards through the through-holes. Liquid droplets entrained in the gas condense on the lower surface of the separation plate, thus achieving the purpose of separating the liquid droplets from the gas. Furthermore, after the droplets condense on the lower surface of the separation plate, the small droplets agglomerate into larger droplets, which can then fall off the separation plate due to gravity.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist: when the separation time is long, a large number of liquid droplets will condense on the separation plate, affecting the gas passage through the through holes and reducing the separation efficiency. Summary of the Invention

[0005] To improve the efficiency of gas-liquid separation, this application provides a high-efficiency gas-liquid separator.

[0006] The high-efficiency gas-liquid separator provided in this application adopts the following technical solution:

[0007] A high-efficiency gas-liquid separator includes a tank body with an inlet pipe and an outlet pipe connected to the tank body. A separation plate with multiple first through holes is disposed inside the tank body. The separation plate is rotatably disposed inside the tank body. Several baffles are disposed on the lower surface of the separation plate. One end of the inlet pipe extends into the tank body, and the end of the inlet pipe extending into the tank body is positioned towards the baffles so that the gas discharged from the inlet pipe can impact the baffles and drive the separation plate to rotate.

[0008] By adopting the above technical solution, after the gas enters the tank through the inlet pipe, it is blocked by the baffle. Due to gravity, initial separation occurs, and large-diameter droplets adhere to the baffle and flow down along it. The gas moves upward and passes through the first through hole to the top of the separation plate. Small droplets in the gas are blocked by the separation plate and temporarily remain on the lower surface of the separation plate. When the small droplets condense into large droplets, they fall off the separation plate. The gas to be separated enters the tank through the inlet pipe. The gas pushes the baffle, which causes the separation plate to rotate. The rotation of the separation plate accelerates the falling of liquid from the separation plate and the baffle, reducing the impact of droplets on the gas passing through the first through hole, thereby improving the separation efficiency.

[0009] Preferably, the baffle is inclined from the end connected to the separation plate to the other end away from the separation plate.

[0010] By adopting the above technical solution, the gas moves along the inclined direction of the baffle on the baffle to reduce resistance and facilitate the rotation of the separation plate.

[0011] Preferably, a rotating shaft is fixedly installed on the separation plate, a first partition is installed inside the tank, a connecting seat is installed on the first partition, and the rotating shaft is rotatably connected to the connecting seat.

[0012] By adopting the above technical solution, the separation plate is fixed on the rotating shaft, and the rotating shaft is rotatably connected to the connecting seat, so as to achieve the purpose of rotating the separation plate.

[0013] Preferably, the connecting seat is provided with a storage cavity, one end of the rotating shaft passes through the storage cavity, the connecting seat is provided with a driving device, the driving device includes a telescopic member and a rotating member for driving the telescopic member to rotate, the telescopic member is provided with a telescopic rod, the telescopic rod is provided with a locking block, the rotating shaft is provided with a slot for the locking block to be inserted, and the locking block can be inserted into the slot to enable the rotating shaft and the telescopic member to rotate synchronously.

[0014] By adopting the above technical solution, the telescopic component extends, allowing the locking block to insert into the slot. The rotating component rotates, which drives the rotating shaft to rotate, causing the rotating shaft to rotate alternately in both directions to throw the liquid off the separator plate. After the gas-liquid separation work is completed or when there are too many liquid droplets on the separator plate, the drive device can drive the separator plate to rotate, further accelerating the drop of liquid off the separator plate.

[0015] Preferably, the air intake pipe includes a first pipe body, a second pipe body, and a third pipe body. The second pipe body is spirally wound around the outer wall of the tank. One end of the first pipe body is connected and fixed to one end of the second pipe body. One end of the third pipe body is connected to the other end of the second pipe body, and the other end of the third pipe body is inserted into the tank.

[0016] By adopting the above technical solution, gas containing droplets enters from the first tube and moves in the rotation direction of the second tube for preliminary separation.

[0017] Preferably, the tank is a cylindrical tank, and the first tube is arranged along the tangent direction of the tank's cross-section.

[0018] By adopting the above technical solution, the first tube is set along the tangent direction of the tank cross-section, so that the resistance of the gas when entering the second tube is small.

[0019] Preferably, a second partition is provided inside the tank, and a second chamber is formed between the second partition and the top plate of the tank. At least two partition plates are provided inside the second chamber. One of the partition plates is fixed to the second partition and has a first gap between it and the top plate of the tank. The other partition plate is fixed to the top plate of the tank and has a second gap between it and the second partition. The partition plates divide the second chamber into a first filter chamber, a second filter chamber, and a third filter chamber. The second filter chamber is located between the first filter chamber and the third filter chamber. The second partition has an opening that communicates with the first filter chamber. The third filter chamber is connected to an exhaust pipe. The first filter chamber, the second filter chamber, and the third filter chamber are all filled with a second separation structure.

[0020] By adopting the above technical solution, the gas after passing through the separation plate enters the first filter chamber through the opening, moves from the first filter chamber to the second filter chamber, moves from the second filter chamber to the third filter chamber and is then discharged through the outlet pipe. When passing through the first filter chamber, the second filter chamber and the third filter chamber, the gas and liquid are separated again by the second separation structure.

[0021] Preferably, the second separation structure includes a frame and a filter element, wherein the frame has filling holes for filling the filter element, and the filter element is configured as a material capable of coalescing the liquid.

[0022] By adopting the above technical solution, the purpose of gas-liquid separation is achieved by separating the gas through the first filter chamber, the second filter chamber and the third filter chamber, so that the separated liquid remains in the first filter chamber, the second filter chamber and the third filter chamber.

[0023] Preferably, the separation plate is configured as a conical umbrella-shaped plate.

[0024] By adopting the above technical solution, the separation plate is set as a conical umbrella-shaped structure, which increases the area of ​​water droplets condensing on the separation plate. Moreover, the umbrella-shaped arrangement of the separation plate facilitates the falling of droplets on the lower surface of the separation plate, which is beneficial to improving the separation efficiency.

[0035] The following is in conjunction with the appendix Figure 1-9This application will be described in further detail.

[0036] This application discloses a high-efficiency gas-liquid separator, referring to... Figure 1 and Figure 2 The high-efficiency gas-liquid separator includes a tank 1, which is a cylindrical tank closed at both ends. The tank 1 is vertically arranged and has a first partition 2 inside, which divides the interior of the tank 1 into a separation chamber 10 and a waste liquid chamber 11. The separation chamber 10 is located between the first partition 2 and the top plate of the tank 1, and the waste liquid chamber 11 is located between the first partition 2 and the bottom plate of the tank 1. The separation chamber 10 is provided with a first separation structure 3 and a second separation structure 4. The tank 1 is connected to an air inlet pipe 5 and an air outlet pipe 6 that are connected to the separation chamber 10. The waste liquid chamber 11 is located at the bottom of the tank 1, and the tank 1 is provided with a waste liquid pipe 110 that is connected to the waste liquid chamber 11.

[0037] The gas to be separated enters the tank 1 through the inlet pipe 5, and is separated twice by the first separation structure 3 and the second separation structure 4 to separate the liquid in the gas. The separated gas is discharged through the outlet pipe 6, and the separated liquid is discharged through the waste liquid pipe 110.

[0038] Reference Figure 1 and Figure 3 The intake pipe 5 includes a first pipe body 50, a second pipe body 51, and a third pipe body 52. ​​The second pipe body 51 is spirally wound around the outer wall of the tank 1. One end of the first pipe body 50 is connected and fixed to one end of the second pipe body 51. The first pipe body 50 is arranged tangentially to the cross-section of the tank 1. One end of the third pipe body 52 is connected to the other end of the second pipe body 51, and the other end of the third pipe body 52 is inserted into the tank 1. Gas containing droplets enters from the first pipe body 50 and moves within the second pipe body 51 along the rotation direction of the second pipe body 51 for initial separation.

[0039] Reference Figure 4 The first separation structure 3 includes a rotating shaft 30 and a separation plate 31. The rotating shaft 30 is vertically arranged, and the separation plate 31 is welded to the top of the rotating shaft 30. The separation plate 31 is arranged in a conical umbrella shape, and the axis of the separation plate 31 coincides with the axis of the rotating shaft 30. A connecting seat 20 is provided on the first partition plate 2, and the rotating shaft 30 is rotatably mounted on the connecting seat 20. The rotating shaft 30 and the separation plate 31 can rotate simultaneously on the rotating shaft 30.

[0040] Referring to the figure, the separation plate 31 is provided with a plurality of evenly arranged first through holes 310, and the lower surface of the separation plate 31 is provided with a plurality of baffles 311. In this application, there are four baffles 311. The baffles 311 are evenly spaced along the axial direction of the separation plate 31, and adjacent baffles 311 are set at an angle. In this application, the angle between adjacent baffles 311 is a right angle or an obtuse angle. The baffles 311 are inclined to the separation plate 31, that is, the baffles 311 are inclined from the end connected to the separation plate 31 to the other end away from the separation plate 31. The end of the third tube 52 that penetrates into the tank 1 can be set perpendicular to the baffles 311.

[0041] After the gas enters the tank 1 through the inlet pipe 5, it is blocked by the baffle 311 and undergoes initial separation by gravity. Large-diameter droplets adhere to the baffle 311 and flow down along the baffle 311. The gas moves upward and moves through the first through hole 310 to the top of the separation plate 31. Small droplets in the gas are blocked by the separation plate 31 and temporarily remain on the lower surface of the separation plate 31. When the small droplets condense into large droplets, they fall off the separation plate 31.

[0042] The gas in the intake pipe 5 pushes the baffle 311, which causes the separation plate 31 to rotate, so that the baffles 311 on the separation plate 31 can come into contact with the gas discharged from the intake pipe 5 in a cyclical manner, thereby reducing the phenomenon of poor separation effect caused by excessive liquid condensation on the surface of a single baffle 311. At the same time, the rotation of the separation plate 31 can accelerate the falling of liquid on the separation plate 31 and the baffles 311.

[0043] Reference Figure 4 The first partition 2 has multiple second through holes 21. After the liquid flowing down the baffle 311 and the liquid on the lower surface of the separation plate 31 fall onto the first partition 2, it enters the waste liquid chamber 11 through the second through holes 21 and is temporarily stored in the waste liquid chamber 11.

[0044] Reference Figure 2 The separation chamber 10 is provided with a second partition 12. The separation chamber 10 includes a first chamber 100 and a second chamber 101. The first chamber 100 is located between the second partition 12 and the first partition 2. The first separation structure 3 is installed in the first chamber 100. The second chamber 101 is located between the second partition 12 and the top plate of the tank body 1. The second separation structure 4 is installed in the second chamber 101.

[0045] Reference Figure 2The second partition 12 has openings 120 for gas passage. The second chamber 101 contains multiple vertically arranged partitions 13. In this application, two partitions 13 are used. One partition 13 is welded to the second partition 12, and a first gap 130 is provided between the partition 13 fixed to the second partition 12 and the top plate of the tank body 1. The other partition 13 is welded to the lower surface of the top plate of the tank body 1, and a second gap 131 is provided between the partition 13 fixed to the top plate of the tank body 1 and the second partition 12. The second chamber 101 includes a first filter chamber 102, a second filter chamber 103, and a third filter chamber 104. The three filter chambers 104 are separated by a partition plate 13. The second filter chamber 103 is located between the first filter chamber 102 and the third filter chamber 104. The opening 120 is connected to the first filter chamber 102, and the air outlet pipe 6 is connected to the third filter chamber 104. The second separation structure 4 is configured to include a frame 40 and a filter element 41 disposed on the frame 40. The frame 40 has multiple honeycomb-shaped filling holes 400. The filter element 41 is filled in the filling holes 400. The filter element 41 is made of a material that can coalesce liquid, such as glass fiber.

[0046] Gas enters the first filter chamber 102 through the opening 120, enters the second filter chamber 103 through the first interval 130, enters the third filter chamber 104 through the second interval 131, and is then discharged through the gas outlet pipe 6.

[0047] Reference Figure 7 The connecting seat 20 is provided with a storage cavity 200. The rotating shaft 30 passes through the top plate of the connecting seat 20 and is rotatably connected to the top plate of the connecting seat 20 through a bearing. The connecting seat 20 is provided with a driving device 7. After the gas-liquid separation work is completed or when there are too many liquid droplets on the separation plate 31, the driving device 7 can drive the separation plate 31 to rotate, further accelerating the drop of liquid on the separation plate 31.

[0048] The driving device 7 includes a rotating component 70, a rotating seat 71, and a telescopic component 72. The rotating seat 71 and the telescopic component 72 are disposed within the storage cavity 200. The telescopic component 72 is vertically welded to the rotating seat 71, and the rotating seat 71 is rotatably connected to the first partition 2. The rotating component 70 is a motor, welded to the lower surface of the first partition 2. The output shaft of the rotating component 70 passes through the first partition 2 and is fixed to the rotating seat 71. The rotating component 70 can drive the rotating seat 71 and the telescopic component 72 to rotate. The telescopic component 72 is an electric push rod, and the telescopic rod of the telescopic component 72 is provided with a cuboid locking block 73. The bottom of the rotating shaft 30 is open. A clearance groove 300 is provided, and a slot 301 for inserting a locking block 73 is provided within the clearance groove 300. The locking block 73 cooperates with the slot 301. A proximity sensor 302 is fixedly installed in the clearance groove 300, and a trigger block 303 is fixed on the telescopic rod. The proximity sensor 302 is connected to a controller for controlling the rotation of the rotating component 70. When the proximity sensor 302 detects the trigger block 303, the rotating component 70 stops rotating, and the telescopic component 72 extends, allowing the locking block 73 to be inserted into the slot 301. The rotation of the rotating component 70 can drive the rotating shaft 30 to rotate, causing the rotating shaft 30 to rotate alternately in both directions to throw the liquid off the partition plate 13.

[0049] The implementation principle of the high-efficiency gas-liquid separator in this application embodiment is as follows: gas enters through the inlet pipe 5 in a rotating manner, and undergoes the first gas-liquid separation in the inlet pipe 5. After entering the tank 1 through the inlet pipe 5, it undergoes the second gas-liquid separation through the separation plate 31. After undergoing the third gas-liquid separation through the second separation structure 4, it is discharged from the outlet pipe 6.

[0050] During the second gas-liquid separation process, the gas pushes the baffle 311, which causes the separation plate 31 to rotate. The rotation of the separation plate 31 accelerates the drop of liquid on the separation plate 31 and the baffle 311, reducing the impact of liquid droplets on the gas passing through the first through hole 310, thereby improving the separation efficiency. After the gas-liquid separation is completed or when there are too many liquid droplets on the separation plate 31, the driving device 7 can drive the separation plate 31 to rotate, further accelerating the drop of liquid on the separation plate 31 and further improving the separation efficiency.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
