Description

Technical Field

[0001] This utility model relates to the field of liquid separation equipment technology, and in particular to a stable and efficient gas-liquid separation device. Background Technology

[0002] Gas-liquid separators are commonly used in industrial processing to separate gases and liquids. Low-pressure, low-flow-rate, high-efficiency gas-liquid separators are often suitable for conditions with low pressure and slow gas flow. Their working principle is to further condense and discharge the liquid entrained in the gas to remove the liquid.

[0003] Traditional gas-liquid separation devices separate the gas and liquid, with the liquid at the bottom of the separation tank and the gas at the top. The liquid is discharged from the drain port at the bottom, and the gas is discharged from the exhaust port at the top. During the gas discharge, a wire mesh demister is used to filter the gas to remove moisture. However, traditional wire mesh demisters are not very effective at filtering small droplets or high-flow-rate gas, and cannot effectively separate small-diameter droplets from the gas and liquid. This makes them unsuitable for increasingly demanding industrial production, and the discharged gas contains a lot of liquid, resulting in unnecessary waste of liquid. Therefore, we propose a stable and efficient gas-liquid separation device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a stable and efficient gas-liquid separation device that can fully separate gas and liquid, thus avoiding the waste of liquid caused by insufficient separation of gas and liquid.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a stable and efficient gas-liquid separation device, comprising a separation tank for gas-liquid separation, an air inlet pipe fixedly connected to one side of the separation tank, a mounting frame fixedly connected to the top of the separation tank, two air outlet pipes fixedly connected to the top of the separation tank, a secondary separation mechanism provided between the mounting frame and the two air outlet pipes, three demister mesh layers fixedly connected inside the separation tank, a spiral guide plate fixedly connected to the inner wall of the separation tank, a primary separation mechanism provided between the separation tank and the mounting frame, the primary separation mechanism being located above the spiral guide plate, and the air inlet pipe being located below the three demister mesh layers.

[0006] A further configuration of this utility model is as follows: the primary separation mechanism includes a servo motor fixedly connected to the top of the mounting frame, an annular tube fixedly sleeved on the inner wall of the separation tank, and a cooling fan fixedly connected to one side of the separation tank. A reciprocating lead screw is fixedly connected to the output shaft of the servo motor, a bearing plate is fixedly connected to one side of the reciprocating lead screw, a lower water-absorbing sponge is fixedly connected to the top of the bearing plate, the cooling fan is connected to the annular tube, and multiple cooling pipes are fixedly connected between the annular tubes. A scraper is fixedly connected to the bottom of one of the cooling pipes. The scraper cooperates with the lower water-absorbing sponge, the top of the lower water-absorbing sponge abuts against the bottom of the cooling pipe, and an air outlet pipe is fixedly connected to one side of the annular tube. One end of the air outlet pipe extends to the outside of the separation tank.

[0007] By adopting the above technical solution, three demister mesh layers are used to perform the first stage of gas filtration, filtering out most of the moisture in the gas. The design of the demister mesh layers improves the filtration effect. Water vapor in the gas is separated on the demister mesh layers, condensing into water droplets that fall to the bottom of the separator and are eventually discharged from the outlet pipe. The gas rises to the spiral guide plate, where it is guided to flow in a spiral pattern. This causes the liquid-containing gas to contact the spiral guide plate and converge at its bottom. The heavier liquid sinks, and the lighter gas rises, allowing it to proceed... The gas and liquid are separated in one step. The separated gas continues to rise between the annular pipe and the cooling pipe. A cold air blower blows cold air into the annular pipe and the cooling pipe, which cools the gas. Water vapor condenses into water droplets when it encounters the cold air, causing the water droplets to accumulate on the cooling pipe, making the gas passing through the cooling pipe drier. At the same time, the servo motor drives the reciprocating screw to rotate, which in turn drives the bearing plate and the lower water-absorbing sponge to rotate, thereby adsorbing the water attached to the cooling pipe. When the lower water-absorbing sponge rotates to abut against the scraper, the lower water-absorbing sponge will be compressed, causing the water inside to be squeezed out.

[0008] A further feature of this invention is that the reciprocating lead screw is located in the gap between the two intermediate cooling pipes.

[0009] By adopting the above technical solution, the reciprocating lead screw and the cooling pipe do not interfere with each other.

[0010] The present invention is further configured as follows: the secondary separation mechanism includes a lifting plate threaded onto the outside of the reciprocating screw, and a lower mesh plate fixedly fitted inside the air outlet pipe. An upper absorbent sponge is movably placed on the top of the lower mesh plate. Two connecting rods are fixedly connected to the bottom of the lifting plate, and a mesh plate is fixedly connected to the bottom end of each of the two connecting rods. The mesh plate movably abuts against the top of the upper absorbent sponge. The secondary separation mechanism also includes baffles fixedly connected to the inner walls of the front and rear sides of the separation tank, and multiple guide vanes are fixedly connected to the bottom of the baffles.

[0011] By adopting the above technical solution, when the gas rises to the baffle, the gas is obstructed, and water condenses on the baffle and guide plate. Finally, the gas is discharged from the two outlet pipes, and after being absorbed by the upper absorbent sponge, the gas and liquid can be further separated. At the same time, the servo motor drives the reciprocating screw to rotate, and the reciprocating screw drives the lifting plate to move up and down. When it moves down, the lifting plate will drive the connecting rod and the mesh plate to move down, squeezing the upper absorbent sponge to discharge the water inside, so as to maintain its good adsorption and improve the gas-liquid separation effect of the device.

[0012] A further feature of this invention is that two limiting rods are fixedly connected between the mounting frame and the separation tank, and the lifting plate is slidably sleeved on the outside of the two limiting rods.

[0013] By adopting the above technical solution, the lifting platform can be guided, making its lifting more stable.

[0014] A further feature of this invention is that a water outlet pipe is fixedly connected to the bottom of the separation tank, and a control valve is provided on the water outlet pipe.

[0015] By adopting the above technical solution, drainage is facilitated.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model uses three demister mesh layers. The demister mesh layers can perform the first filtration of the gas, filtering out most of the moisture in the gas. The design of the demister mesh layers makes the filtration effect better. The water vapor in the gas will be separated on the demister mesh layers, and will collect into water droplets and fall to the bottom of the separation tank, and finally be discharged from the water outlet pipe. The gas rises and reaches the spiral guide plate. The spiral guide plate guides the gas to flow in a spiral, so that the liquid-containing gas comes into contact with the spiral guide plate and gathers at the bottom of the spiral guide plate. The heavier liquid sinks and the lighter gas rises, which can further separate the gas and liquid.

[0018] 2. After separation, the gas continues to rise between the annular pipe and the cooling pipe. A cold air blower blows cold air into the annular pipe and the cooling pipe, which cools the gas. Water vapor condenses into water droplets when it encounters the cold air, causing the water droplets to accumulate on the cooling pipe, making the gas passing through the cooling pipe drier. At the same time, the servo motor drives the reciprocating screw to rotate, which in turn drives the bearing plate and the lower water-absorbing sponge to rotate, thereby adsorbing the water attached to the cooling pipe. When the lower water-absorbing sponge rotates to contact the scraper, the lower water-absorbing sponge will be compressed, causing the water inside to be squeezed out.

[0019] 3. In this invention, when the gas rises to the baffle, the gas is obstructed, and water condenses on the baffle and guide plate. Finally, the gas is discharged from the two outlet pipes, and after being absorbed by the upper absorbent sponge, the gas and liquid can be further separated. At the same time, the servo motor drives the reciprocating screw to rotate, and the reciprocating screw drives the lifting plate to move up and down. When it moves down, the lifting plate will drive the connecting rod and the mesh plate to move down, squeezing the upper absorbent sponge to discharge the water inside, so as to maintain its good adsorption and improve the gas-liquid separation effect of the device.

Detailed Implementation

[0027] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] See Figure 1 — Figure 5 This utility model provides a stable and efficient gas-liquid separation device, including a separation tank 1 for gas-liquid separation. An air inlet pipe 2 is fixedly connected to one side of the separation tank 1. A mounting frame 5 is fixedly connected to the top of the separation tank 1. Two air outlet pipes 4 are fixedly connected to the top of the separation tank 1. A secondary separation mechanism 7 is provided between the mounting frame 5 and the two air outlet pipes 4. Three demister mesh layers 8 are fixedly connected inside the separation tank 1. A spiral guide plate 9 is fixedly connected to the inner wall of the separation tank 1. A primary separation mechanism 6 is provided between the separation tank 1 and the mounting frame 5. The primary separation mechanism 6 is located above the spiral guide plate 9.

[0029] Specifically, refer to Figures 1-4 The primary separation mechanism 6 includes a servo motor 62 fixedly connected to the top of the mounting frame 5, an annular tube 64 fixedly sleeved on the inner wall of the separation tank 1, and a cooler 61 fixedly connected to one side of the separation tank 1. A reciprocating screw 63 is fixedly connected to the output shaft of the servo motor 62. A bearing plate 67 is fixedly connected to one side of the reciprocating screw 63. A lower water-absorbing sponge 68 is fixedly connected to the top of the bearing plate 67. The cooler 61 is connected to the annular tube 64. Multiple cooling pipes 69 are fixedly connected between the annular tubes 64. A scraper 66 is fixedly connected to the bottom of one of the cooling pipes 69. The scraper 66 cooperates with the lower water-absorbing sponge 68.

[0030] Using the above scheme: the separated gas continues to rise between the annular pipe 64 and the cooling pipe 69. The cold air blown by the cold air fan 61 can blow cold air into the annular pipe 64 and the cooling pipe 69. The cooling pipe 69 will cool the gas. Water vapor will condense into water droplets when it encounters the cold, and the water droplets will accumulate on the cooling pipe 69, making the gas passing through the cooling pipe 69 drier. At the same time, the servo motor 62 drives the rotation of the reciprocating screw 63. The reciprocating screw 63 drives the rotation of the bearing plate 67 and the lower water-absorbing sponge 68, which can then absorb the water attached to the cooling pipe 69. When the lower water-absorbing sponge 68 rotates to abut against the scraper 66, the lower water-absorbing sponge 68 will be compressed, and the water inside it will be squeezed out.

[0031] Specifically, an air outlet pipe 65 is fixedly connected to one side of the annular pipe 64, and one end of the air outlet pipe 65 extends to the outside of the separation tank 1.

[0032] Specifically, the reciprocating lead screw 63 is located in the gap between the two intermediate cooling pipes 69.

[0033] Specifically, the top of the lower absorbent sponge 68 abuts against the bottom of the cooling pipe 69.

[0034] Specifically, refer to Figures 1-3 and Figure 5 The secondary separation mechanism 7 includes a lifting plate 72 threaded onto the outside of the reciprocating screw 63, and a lower mesh plate 76 fixedly fitted inside the air outlet pipe 4. An upper absorbent sponge 75 is movably placed on the top of the lower mesh plate 76. Two connecting rods 73 are fixedly connected to the bottom of the lifting plate 72. A mesh plate 74 is fixedly connected to the bottom of each of the two connecting rods 73. The mesh plate 74 movably abuts against the top of the upper absorbent sponge 75. The secondary separation mechanism 7 also includes baffles 77 fixedly connected to the inner walls of the front and rear sides of the separation tank 1. Multiple guide vanes are fixedly connected to the bottom of the baffles 77.

[0035] Using the above scheme: when the gas rises to the baffle 77, the gas is obstructed, and water condenses on the baffle 77 and the guide plate. Finally, the gas is discharged from the two gas outlet pipes 4, and after being absorbed by the upper water-absorbing sponge 75, the gas and liquid can be further separated. At the same time, the servo motor 62 drives the reciprocating screw 63 to rotate, and the reciprocating screw 63 drives the lifting plate 72 to move up and down. When it moves down, the lifting plate 72 will drive the connecting rod 73 and the mesh plate 74 to move down, squeezing the upper water-absorbing sponge 75 to discharge the water inside, so as to maintain its good adsorption and improve the gas-liquid separation effect of the device.

[0036] Specifically, there are two limiting rods 71 ​​fixedly connected between the mounting frame 5 and the separation tank 1, and the lifting plate 72 is slidably sleeved on the outside of the two limiting rods 71.

[0037] Specifically, the bottom of the separator 1 is fixedly connected to a water outlet pipe 3, and a control valve is installed on the water outlet pipe 3.

[0038] Specifically, the intake pipe 2 is located below the three demister mesh layers 8.

[0039] In this invention, gas enters through the inlet pipe 2 and passes through three demister mesh layers 8. These layers perform the first filtration, removing most of the moisture. The design of the demister mesh layers 8 enhances the filtration effect. Water vapor in the gas is separated on the demister mesh layers 8, accumulating into droplets that fall to the bottom of the separator tank 1 and are eventually discharged from the outlet pipe 3. The gas rises to the spiral guide plate 9, where it flows in a spiral pattern. This causes the liquid-containing gas to contact the spiral guide plate 9 and converge at its bottom. The heavier liquid sinks, while the lighter gas rises, further separating the gas and liquid. The separated gas continues to rise between the annular pipe 64 and the cooling pipe 69. A cool air blower 61 blows cool air into the annular pipe 64 and the cooling pipe 69, cooling the gas. The water vapor condenses into droplets upon contact with the cool air, accumulating on the cooling pipe 69. This allows the gas to pass through the cooling pipe 69 more effectively. The gas in section 9 is drier, and the servo motor 62 drives the reciprocating screw 63 to rotate. The reciprocating screw 63 drives the bearing plate 67 and the lower water-absorbing sponge 68 to rotate, thereby absorbing the water attached to the cooling pipe 69. When the lower water-absorbing sponge 68 rotates to abut against the scraper 66, the lower water-absorbing sponge 68 will be compressed, squeezing out the water inside and causing the water to flow downwards. At the same time, when the gas rises to the baffle 77, the gas is obstructed, and the water is trapped between the baffle 77 and the guide plate. The gas condenses at the top and is finally discharged from the two outlet pipes 4. After being absorbed by the upper absorbent sponge 75, the gas and liquid are further separated. At the same time, the servo motor 62 drives the reciprocating screw 63 to rotate, and the reciprocating screw 63 drives the lifting plate 72 to move up and down. When it moves down, the lifting plate 72 will drive the connecting rod 73 and the mesh plate 74 to move down and squeeze the upper absorbent sponge 75 to discharge the water inside, so as to maintain its good adsorption and improve the gas-liquid separation effect of the device.
