Description

Technical Field

[0001] This invention belongs to the field of gas-liquid separation technology, specifically relating to a portable high-efficiency gas-liquid fiber separator. Background Technology

[0002] Gas-liquid separation plays a vital role in the petroleum industry and other industrial sectors. The separated gas and liquid are easier to handle and transport, which can improve production efficiency and output, reduce production costs, and thus enhance the competitiveness of enterprises. Some components in the mixture may be hazardous. Through gas-liquid separation, these hazardous components can be separated out, ensuring the safety of the production process and reducing environmental pollution.

[0003] Chinese patent application CN201921423582.9 discloses a gas-liquid separation device, comprising: a container tank with a gas inlet and a liquid outlet on its side wall, and a gas outlet on its top; a fiber bed structure located between the gas inlet and the gas outlet; the fiber bed structure includes a fiber bed and a tube sheet; the fiber bed includes a cylindrical inner skeleton, at least three fiber layers wound around the inner skeleton, and an outer skeleton sleeved on the outside of the fiber layers, with one end of the inner skeleton welded to the tube sheet; the fiber bed also includes a bottom plate, which is fixedly connected to the ends of the inner skeleton and the outer skeleton away from the tube sheet; each fiber layer is formed by spirally winding fibers around the inner skeleton, the fibers in the middle layer of several fiber layers are made of a liquid-repellent material, and the fibers in the fiber layers tightly attached to the inner skeleton have a diameter of 100-300 μm. This patent has a good effect on removing droplets with a diameter of less than 3 μm from the gas.

[0004] In the process of separating liquids, gas-liquid separators are prone to re-carrying the separated liquids, which reduces the separation efficiency. At the same time, the liquid separation effect of gas-liquid separators is an important factor in evaluating the device and is one of the key research directions. Summary of the Invention

[0005] To address the aforementioned shortcomings, this invention provides a high-efficiency gas-liquid fiber separator with anti-carrying properties. This invention effectively removes the liquid from the gas-liquid mixture and ensures that the discharged liquid is quickly guided out and does not excessively contact the gas-liquid mixture, preventing the gas-liquid mixture from carrying away the separated liquid and thus affecting the separation efficiency. This invention ensures that the gas is completely separated, resulting in good separation effect and high separation efficiency. This invention comprehensively and effectively prevents liquid carryover and achieves high separation efficiency.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A portable, high-efficiency gas-liquid fiber separator includes a separation tank. The lower side of the separation tank has an inlet, the bottom of the separation tank has a first drain outlet, and the upper side of the separation tank has a second drain outlet. A partition is sealed inside the separation tank between the first and second drain outlets, dividing the separation tank into a lower first drain space and an upper second drain space. Multiple gas-liquid fiber separators are evenly installed on the partition, with their outlets facing the interior of the first drain space. A gas-liquid separation grid is fixedly connected inside the separation tank above the second drain outlet, and an outlet is located at the top of the separation tank.

[0008] The gas-liquid fiber separator includes a wire mesh layer, which wraps around and forms the outer wall of the gas-liquid fiber separator; the wire mesh layer is bent upwards and gathered to form the gas outlet of the gas-liquid fiber separator; the side wall of the gas-liquid fiber separator is divided into three layers from the outside to the inside, namely the wire mesh layer, the fiber layer and the liquid drainage layer; the liquid drainage layer has a porous structure; the bottom of the gas-liquid fiber separator is sealed and connected to a conical guide tube, and a one-way valve is provided at the bottom end of the conical guide tube.

[0009] Preferably, the angle between the wall of the tapered guide tube and the horizontal direction is 80-85°.

[0010] More preferably, the mesh layer is a metal mesh with a contact angle greater than 150° with the liquid surface; the fiber layer has a contact angle between 90° and 110° with the liquid surface.

[0011] More preferably, the metal mesh material of the mesh layer is stainless steel mesh or copper mesh.

[0012] More preferably, the gas-liquid fiber separator has a tubular structure, and the wire mesh layer is arranged vertically.

[0013] Preferably, the gas-liquid separation grid includes a first fiber block and a second fiber block, which are evenly spaced on the gas-liquid separation grid. The contact angle between the first fiber block and the liquid surface is smaller than that between the second fiber block and the liquid surface. The bottom of the first fiber block is a concave structure, and the bottom of the second fiber block is a convex spherical structure. The curved surface of the concave structure is connected to the curved surface of the adjacent spherical structure.

[0014] More preferably, the gas-liquid fiber separator corresponds one-to-one with the first fiber block, and the gas outlet of the gas-liquid fiber separator is located directly below the concave structure of the corresponding first fiber block.

[0015] More preferably, the contact angle between the first fiber block and the liquid is between 90° and 110°, and the contact angle between the second fiber block and the liquid is between 130° and 150°.

[0016] More preferably, the maximum thickness of the second fiber block is 200-300 mm, and the maximum thickness of the first fiber block is 100-200 mm.

[0017] Preferably, the porosity of the first fiber block is less than 80%, and the porosity of the second fiber block is between 85% and 90%.

[0018] This invention also claims a gas-liquid separation method using the above-described combined gas-liquid fiber separator, comprising the following steps:

[0019] S1. The gas-liquid mixture is fed into the feed inlet. The gas-liquid mixture quickly comes into contact with the wire mesh layer along the wall of the conical guide tube. The gas-liquid mixture passes through the wire mesh layer and the fiber layer in sequence to achieve separation and aggregation. The liquid is discharged into the conical guide tube through the drain layer. The treated gas enters the second drain space through the gas outlet of the gas-liquid fiber separator.

[0020] S2. The treated gas passes through the gas-liquid separation grid and the remaining liquid is condensed by the first fiber block. The condensed liquid flows from the concave surface of the concave structure to the spherical surface of the spherical structure. Finally, the liquid drips down at the junction of the concave and spherical structures and falls into the baffle to prevent the gas outlet of the gas-liquid fiber separator from carrying more liquid droplets. The gas after the liquid is condensed overflows from the concave structure of the first fiber block and is isolated and separated by the second fiber block, so that the gas is finally completely separated.

[0021] S3. The separated gas is discharged from the gas outlet, the liquid separated by the gas-liquid separation grid is discharged from the second drain outlet, and the liquid separated by the gas-liquid fiber separator is discharged through the first drain outlet.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) In this invention, a gas-liquid mixture is first introduced through the feed inlet. The gas-liquid mixture can quickly come into contact with the vertically arranged wire mesh layer through the conical guide tube with an 80-85° pipe wall, thereby increasing the contact area with the wire mesh layer and improving the separation efficiency. Through the multi-layer structure of the gas-liquid fiber separator, which consists of a wire mesh layer, a fiber layer, and a drain layer from the outside to the inside, the gas-liquid mixture first comes into contact with the wire mesh layer over a large area. The large contact angle of the wire mesh layer blocks most of the liquid outside the wire mesh. The small contact angle of the second fiber layer allows the liquid to be collected and the gas to pass through. Finally, the liquid is drained through the adjacent porous drain layer. The liquid discharged from the drain layer flows out quickly through the conical guide tube and is discharged through a one-way valve. The liquid blocked by the wire mesh layer flows down quickly from the outside of the conical guide tube. This combination effectively removes the liquid in the gas-liquid mixture and ensures that the discharged liquid flows out quickly without excessive contact with the gas-liquid mixture, so that the gas-liquid mixture does not carry the separated liquid again, thereby affecting the separation efficiency.

[0024] (2) This invention utilizes uniformly spaced first and second fiber blocks, and the combination of the small contact angle of the first fiber block and the large contact angle of the second fiber block, to ensure that the gas treated by the gas-liquid fiber separator can be processed uniformly and without dead angles from all directions. The gas-liquid fiber separator is designed to correspond one-to-one with the first fiber block, with the outlet of the gas-liquid fiber separator located directly below the concave structure of the corresponding first fiber block. This design allows the gas containing liquid to be processed first by the first fiber block, where the liquid condenses and then forms along the curved surface of the concave structure and adjacent spherical surfaces. The curved surface of the structure prevents the condensed liquid from flowing into the outlet of the gas-liquid fiber separator and colliding with the gas to be treated multiple times, thus preventing the liquid from being carried away again. Instead, the liquid falls onto the baffle and is eventually discharged. Under the action of the first fiber block with a porosity of less than 80%, the gas after the liquid is condensed overflows from the periphery of the first fiber block to the outside. It is then separated by the second fiber block with a porosity of 85% to 90%, and the liquid does not pass through the second fiber block. Through the combination of the contact angle between the liquid and the fiber and the design of their respective porosities, the gas is finally completely separated, resulting in good separation effect and high separation efficiency.

[0025] (3) The combined design of the tubular gas-liquid fiber separator and the gas-liquid separation grid of this invention firstly separates the gas-liquid mixture over a large area longitudinally through the vertically arranged gas-liquid fiber separator. It is initially separated by the multi-layer structure of the wire mesh layer, fiber layer and liquid drainage layer. Since the movement trajectory of the gas-liquid mixture is disordered, the effect of the gas-liquid fiber separator on the gas-liquid mixture in different directions is also different. It is then further processed by the horizontally arranged gas-liquid separation grid. Through the cooperation of the first fiber block and the second fiber block, the final gas separation effect is good and the structure is simple. Furthermore, through the conical guide tube and one-way valve structure design of the tubular gas-liquid fiber separator, this invention can enable the gas-liquid mixture to quickly contact the wire mesh layer. At the same time, the inner and outer walls of the conical guide tube can quickly guide the discharged liquid out and flow out with the gas-liquid mixture. By avoiding excessive contact, the probability of the gas-liquid mixture carrying the separated liquid again is reduced, thus affecting separation efficiency. The one-way valve allows the separated liquid to flow out in one direction, preventing external gas-liquid mixtures from entering the gas-liquid fiber separator from the bottom, thereby reducing the probability of the separated gas carrying liquid again. At the same time, through the structural design of the gas-liquid separation grid, the condensed liquid will not flow into the gas outlet of the gas-liquid fiber separator and collide with the gas to be treated multiple times, causing the liquid to be carried again. Instead, it will fall onto the baffle and be discharged. Furthermore, through the alternating design of the concave curved surface and spherical structure, the gas coming out of the gas outlet of the gas-liquid fiber separator is processed and separated separately, without mixing with the processing of other units, reducing the probability of the gas carrying liquid again. This comprehensive approach effectively prevents liquid carryover and achieves high separation efficiency. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. Of course, the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] Although the steps in this invention are arranged by reference numerals, this is not intended to limit the order of the steps. Unless the order of the steps is explicitly stated or the execution of a step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" as used herein refers to and covers any and all possible combinations of one or more of the associated listed items.

[0033] The specific operating principle of the portable high-efficiency gas-liquid fiber separator of the present invention is as follows:

[0034] This invention first introduces a gas-liquid mixture into an inlet 500, located below a separator 100. After entering the separator 100, the gas-liquid mixture comes into contact with multiple gas-liquid fiber separators 400 inside the separator 100, which are evenly and vertically arranged on partitions within the separator 100. The gas-liquid mixture, through a tapered guide tube 440 with an 80-85° wall angle, can quickly contact the vertically arranged mesh layer 410, increasing the contact area with the mesh layer 410 and improving efficiency. To improve separation efficiency, the angle between the wall of the conical guide tube 440 and the horizontal direction can be, for example, 80°, 81°, 82°, 83°, 84°, or 85°. The gas-liquid mixture is separated and aggregated by sequentially passing through the wire mesh layer 410 and the fiber layer 420. First, the large contact angle of the wire mesh layer 410 prevents most of the liquid from being blocked outside the mesh. The wire mesh layer 410 is made of metal wire mesh, such as stainless steel or copper wire mesh, and the contact angle between the wire mesh layer 410 and the liquid surface is greater than 150°, for example, 15°. 1°, 153°, 155°, 157°, 160°, 163°, 165°, 158°, 170°, 173°, 175°, 177°, 179°; then, through the small contact angle of the second fiber layer 420, the liquid is collected and the gas permeates. For example, the contact angle between the fiber layer 420 and the liquid surface can be 90°, 93°, 95°, 97°, 100°, 103°, 105°, 107°, 110°; finally, through the adjacent porous drainage layer 430... The gas-liquid mixture undergoes a drainage process to effectively remove the liquid from the gas-liquid mixture. A one-way valve 441 ensures the separated liquid flows out in one direction, preventing external gas-liquid mixtures from entering the gas-liquid fiber separator 400 from the bottom, thus reducing the probability of the separated gas carrying liquid again. Liquid discharged from the drainage layer 430 flows rapidly out through the conical guide pipe 440 and is discharged through the one-way valve 441. Liquid blocked by the mesh layer 410 flows rapidly down from the outside of the conical guide pipe 440, effectively removing the liquid from the gas-liquid mixture. Furthermore, the rapid flow of the discharged liquid avoids excessive contact with the gas-liquid mixture, preventing the mixture from carrying the separated liquid again and affecting separation efficiency. The treated gas enters the second drainage space through the outlet of the gas-liquid fiber separator 400.

[0035] The treated gas passes through the gas-liquid separation grid 300. The horizontally arranged gas-liquid separation grid 300 allows the gas treated by the gas-liquid fiber separator 400 to be processed again in all directions, uniformly, and without dead angles. The first fiber block 310 and the second fiber block 320 are evenly distributed. The contact angle between the first fiber block 310 and the liquid is between 90° and 110°, for example, 90°, 92°, 94°, 96°, 98°, 100°, 102°, 104°, 106°, 108°, and 110°. The contact angle between the second fiber block 320 and the liquid is between 130° and 150°, for example, 130°, 133°, 135°, 137°, 140°, 143°, 145°, 147°, and 150°. The maximum thickness of the second fiber block 320 is 200-300 mm, for example, 200 mm, 220 mm, 240 mm, 260 mm, 280 mm, or 300 mm; the maximum thickness of the first fiber block 310 is 100-200 mm, for example, 100 mm, 120 mm, 140 mm, 160 mm, 180 mm, or 200 mm; the porosity of the first fiber block 310 is less than 80%, for example, 79% or 78%. 77%, 76%, 75%, 74%, 73%, 72%, 71%, 70%; the porosity of the second fiber block 320 is between 85% and 90%, for example, 85%, 86%, 87%, 88%, 89%, 90%; through the combination of the small contact angle of the first fiber block 310 and the large contact angle of the second fiber block 320, the gas treated by the gas-liquid fiber separator 400 can be uniformly and thoroughly processed without dead angles. Corresponding one-to-one with the first fiber block 310, the air outlet of the gas-liquid fiber separator 400 is located directly below the concave structure 311 of the corresponding first fiber block 310. This structural design ensures that the gas containing liquid is first processed by the first fiber block 310, and the liquid is condensed on the first fiber block 310. Then, it flows down along the curved surface of the concave structure 311 and the curved surface of the adjacent spherical structure 321, preventing the condensed liquid from flowing into the air outlet of the gas-liquid fiber separator 400 and colliding with the gas to be treated multiple times, thus preventing the liquid from being carried away again. Instead, it falls onto the partition 200 and is eventually discharged. Under the action of the first fiber block 310 with a porosity of less than 80%, the gas after the liquid is condensed overflows from the periphery of the first fiber block 310 to the outside and is isolated and separated by the second fiber block 320 with a porosity of 85% to 90%. The liquid will not pass through the second fiber block 320. Through the combination of the contact angle between the liquid and the fiber and the design of their respective porosities, the gas is finally completely separated, resulting in good separation effect and high separation efficiency.Due to the porosity structure and contact angle of the first fiber block 310 and the second fiber block 320, the liquid will not condense when the gas containing liquid is in the second fiber block 320. Instead, the liquid will condense first in the first fiber block 310. The gas will not pass through the first fiber block 310 but will overflow outwards from the periphery of the first fiber block 310 and be processed by the second fiber block 320. The residual liquid is isolated, while the gas will pass through the second fiber block 320 and be separated, so that the gas is completely separated. The separation effect is good. The separated gas is discharged from the gas outlet 800, and the liquid is discharged from the second liquid outlet 700.

[0036] Through the combined design of the tubular gas-liquid fiber separator 400 and the gas-liquid separation grid 300, the gas-liquid mixture first undergoes large-area longitudinal separation through the vertically arranged gas-liquid fiber separator 400, and is initially separated by the multi-layer structure of the mesh layer 410, fiber layer 420, and drainage layer 430. Since the movement trajectory of the gas-liquid mixture is disordered, the effect of the gas-liquid fiber separator 400 on the gas-liquid mixture in different directions is also different. It is then further processed by the horizontally arranged gas-liquid separation grid 300. Through the cooperation of the first fiber block 310 and the second fiber block 320, the final gas separation effect is good, and the structure is simple. Furthermore, through the structural design of the conical guide tube 440 and the one-way valve 441 of the tubular gas-liquid fiber separator 400, the gas-liquid mixture can quickly come into contact with the mesh layer 410, and the inner and outer walls of the conical guide tube 440 can quickly guide the discharged liquid. The gas-liquid mixture does not come into excessive contact with the outflow, reducing the probability that the gas-liquid mixture will carry the separated liquid again, thus affecting the separation efficiency. The one-way valve 441 allows the separated liquid to flow out in one direction, preventing external gas-liquid mixtures from entering the gas-liquid fiber separator 400 from the bottom, thereby reducing the probability that the separated gas will carry the liquid again. At the same time, through the structural design of the gas-liquid separation grid 300, the condensed liquid will not flow into the outlet of the gas-liquid fiber separator 400 and collide with the gas to be treated multiple times, causing the liquid to be carried again. Instead, it will fall onto the baffle 200 and be discharged. Furthermore, through the alternating design of the curved surface of the concave structure 311 and the spherical structure 321, the gas coming out of the outlet of the gas-liquid fiber separator 400 is processed and separated separately, without mixing or crossing with the processing of other units, reducing the probability that the gas will carry the liquid again. This comprehensive approach effectively prevents liquid carryover and achieves high separation efficiency.

[0037] Example 1

[0038] like Figures 1-4As shown, a portable high-efficiency gas-liquid fiber separator includes a separation tank 100. A feed inlet 500 is located on the lower side of the separation tank 100. A first drain outlet 600 is located at the bottom of the separation tank 100, and a second drain outlet 700 is located on the upper side of the separation tank 100. A partition 200 is enclosed inside the separation tank 100 between the first drain outlet 600 and the second drain outlet 700, dividing the separation tank 100 into a lower first drain space and an upper second drain space. Multiple gas-liquid fiber separators 400 are evenly installed on the partition 200, with the air outlets of the gas-liquid fiber separators 400 facing the interior of the first drain space. A gas-liquid separation grid 300 is fixedly connected inside the separation tank 100 above the second drain outlet 700, and an air outlet 800 is located at the top of the separation tank 100.

[0039] It is worth noting that the height of the air outlet of the gas-liquid fiber separator 400 is higher than the height of the second drain outlet 700, so that the liquid can be drained smoothly.

[0040] The gas-liquid fiber separator 400 includes a mesh layer 410, which wraps around to form the outer wall of the gas-liquid fiber separator 400; the mesh layer 410 is bent upwards to form the air outlet of the gas-liquid fiber separator 400; the side wall of the gas-liquid fiber separator 400 is divided into three layers from the outside to the inside, namely the mesh layer 410, the fiber layer 420 and the drain layer 430; the drain layer 430 has a porous structure; the bottom of the gas-liquid fiber separator 400 is sealed and connected to a conical guide pipe 440, and a one-way valve 441 is provided at the bottom end of the conical guide pipe 440.

[0041] Preferably, the angle between the wall of the tapered guide tube 440 and the horizontal direction is 80-85°.

[0042] More preferably, the mesh layer 410 is a metal mesh with a contact angle greater than 150° with the liquid surface; the fiber layer 420 has a contact angle between 90° and 110° with the liquid surface.

[0043] This invention first introduces a gas-liquid mixture through the inlet 500. The gas-liquid mixture, passing through a tapered guide tube 440 with an 80-85° wall angle, quickly contacts the vertically arranged wire mesh layer 410, increasing the contact area and improving separation efficiency. The gas-liquid fiber separator 400 has a multi-layered structure consisting of a wire mesh layer 410, a fiber layer 420, and a drain layer 430, from the outside in. This allows the gas-liquid mixture to first contact the wire mesh layer 410 over a large area. The large contact angle of the wire mesh layer 410 prevents most of the liquid from being trapped outside the mesh. The mixture then passes through the second layer... The small contact angle of the fiber layer 420 allows the liquid to be collected and the gas to pass through. Finally, the liquid is drained through the adjacent porous drainage layer 430. The liquid discharged from the drainage layer 430 flows out quickly through the conical guide tube 440 and is discharged through the one-way valve 441. The liquid blocked by the wire mesh layer 410 flows down quickly from the outside of the conical guide tube 440. This combination effectively removes the liquid from the gas-liquid mixture and ensures that the discharged liquid flows out quickly without excessive contact with the gas-liquid mixture, so that the gas-liquid mixture does not carry the separated liquid again, thus affecting the separation efficiency.

[0044] More preferably, the metal mesh material of the mesh layer 410 is stainless steel mesh or copper mesh.

[0045] More preferably, the gas-liquid fiber separator 400 has a tubular structure, and the wire mesh layer 410 is vertically arranged. The tubular structure of the gas-liquid fiber separator 400 greatly increases the contact area between the wire mesh layer 410 and the gas-liquid mixture. At the same time, the vertical structure design of the wire mesh layer 410 facilitates the longitudinal separation of the gas-liquid mixture and increases the effective area.

[0046] Preferably, the gas-liquid separation grid 300 includes a first fiber block 310 and a second fiber block 320, which are evenly spaced on the gas-liquid separation grid 300. The contact angle between the first fiber block 310 and the liquid surface is smaller than that between the second fiber block 320 and the liquid surface. The bottom of the first fiber block 310 is a concave surface structure 311, and the bottom of the second fiber block 320 is a convex spherical surface structure 321. The curved surface of the concave surface structure 311 connects with the curved surface of the adjacent spherical surface structure 321. This transversely arranged structural design of the gas-liquid separation grid 300 facilitates the transverse separation of the gas-liquid mixture, thereby achieving deep separation.

[0047] More preferably, the gas-liquid fiber separator 400 corresponds one-to-one with the first fiber block 310, and the air outlet of the gas-liquid fiber separator 400 is located directly below the concave structure 311 of the corresponding first fiber block 310.

[0048] More preferably, the contact angle between the first fiber block 310 and the liquid is between 90° and 110°, and the contact angle between the second fiber block 320 and the liquid is between 130° and 150°.

[0049] More preferably, the maximum vertical thickness of the second fiber block 320 is 200-300 mm, and the maximum vertical thickness of the first fiber block 310 is 100-200 mm.

[0050] Preferably, the porosity of the first fiber block 310 is less than 80%, and the porosity of the second fiber block 320 is between 85% and 90%.

[0051] This invention utilizes uniformly spaced first fiber blocks 310 and second fiber blocks 320, and through the combination of the small contact angle of the first fiber block 310 and the large contact angle of the second fiber block 320, ensures that the gas treated by the gas-liquid fiber separator 400 can be uniformly and thoroughly processed without any dead angles. The gas-liquid fiber separator 400 corresponds one-to-one with the first fiber block 310, and the outlets of the gas-liquid fiber separator 400 are all located directly below the concave structure 311 of the corresponding first fiber block 310. This design allows the gas containing liquid to be first processed by the first fiber block 310, where the liquid condenses and then flows down the concave structure 311. The curved surface and the curved surface of the adjacent spherical structure 321 flow downwards, so that the condensed liquid will not flow into the outlet of the gas-liquid fiber separator 400 and collide with the gas to be treated multiple times, causing the liquid to be carried again. Instead, it falls onto the partition 200 and is eventually discharged. Under the action of the first fiber block 310 with a porosity of less than 80%, the gas after the liquid is condensed overflows from the periphery of the first fiber block 310 to the outside. It is isolated and separated by the second fiber block 320 with a porosity of 85% to 90%, and the liquid will not pass through the second fiber block 320. Through the combination of the contact angle between the liquid and the fiber and the design of their respective porosities, the gas is finally completely separated, with good separation effect and high separation efficiency.

[0052] Example 2

[0053] A gas-liquid separation method using the above-mentioned combined gas-liquid fiber separator includes the following steps:

[0054] S1. The gas-liquid mixture is introduced into the feed port 500. The gas-liquid mixture quickly comes into contact with the wire mesh layer 410 along the wall of the conical guide tube 440. The gas-liquid mixture is separated and aggregated by passing through the wire mesh layer 410 and the fiber layer 420 in sequence. The liquid is discharged into the conical guide tube 440 through the drain layer 430. The treated gas enters the second drain space through the gas outlet of the gas-liquid fiber separator 400.

[0055] S2. The treated gas passes through the gas-liquid separation grid 300 and the remaining liquid is condensed by the first fiber block 310. The condensed liquid flows from the curved surface of the concave structure 311 to the curved surface of the spherical structure 321. Finally, the liquid drips down at the junction of the concave structure 311 and the spherical structure 321 and falls into the baffle 200 to prevent the gas outlet of the gas-liquid fiber separator 400 from carrying more liquid droplets. The gas after the liquid is condensed overflows from the concave structure 311 of the first fiber block 310 and is isolated and separated by the second fiber block 320, so that the gas is finally completely separated.

[0056] S3. The separated gas is discharged from the outlet 800, the liquid separated by the gas-liquid separation grid 300 is discharged from the second drain port 700, and the liquid separated by the gas-liquid fiber separator 400 is discharged through the first drain port 600.

[0057] The present invention combines a tubular gas-liquid fiber separator 400 and a gas-liquid separation grid 300. Firstly, the gas-liquid mixture undergoes large-area longitudinal separation through the vertically arranged gas-liquid fiber separator 400, initially separated by a multi-layered structure of mesh layer 410, fiber layer 420, and drainage layer 430. Since the movement trajectory of the gas-liquid mixture is disordered, the effect of the gas-liquid fiber separator 400 on the gas-liquid mixture in different directions varies. Further processing is achieved through the horizontally arranged gas-liquid separation grid 300. Through the combined action of the first fiber block 310 and the second fiber block 320, the final gas separation effect is good, and the structure is simple. Furthermore, the present invention, through the structural design of the conical guide tube 440 and the one-way valve 441 of the tubular gas-liquid fiber separator 400, allows the gas-liquid mixture to quickly contact the mesh layer 410, while the inner and outer walls of the conical guide tube 440 can quickly guide the discharged liquid. The gas-liquid mixture does not come into excessive contact with the outflow, reducing the probability that the gas-liquid mixture will carry the separated liquid again, thus affecting the separation efficiency. The one-way valve 441 allows the separated liquid to flow out in one direction, preventing external gas-liquid mixtures from entering the gas-liquid fiber separator 400 from the bottom, thereby reducing the probability that the separated gas will carry the liquid again. At the same time, through the structural design of the gas-liquid separation grid 300, the condensed liquid will not flow into the outlet of the gas-liquid fiber separator 400 and collide with the gas to be treated multiple times, causing the liquid to be carried again. Instead, it will fall onto the baffle 200 and be discharged. Furthermore, through the alternating design of the curved surface of the concave structure 311 and the spherical structure 321, the gas coming out of the outlet of the gas-liquid fiber separator 400 is processed and separated separately, without mixing or crossing with the processing of other units, reducing the probability that the gas will carry the liquid again. This comprehensive approach effectively prevents liquid carryover and achieves high separation efficiency.

[0058] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
