Description

Technical Field

[0001] This utility model relates to a chemical equipment, and more specifically, to a screen-type gas-liquid separation device. Background Technology

[0002] In industrial production, the separation of gas-liquid mixtures is a common and important process, widely used in chemical, petroleum, environmental protection, food processing, and pharmaceutical industries. The purpose of gas-liquid separation is to effectively separate gases and liquids to meet subsequent process requirements or emission standards. Traditional gas-liquid separation methods mainly include gravity separation, centrifugal separation, filtration separation, and membrane separation. Gravity separation utilizes the density difference between gases and liquids to achieve natural separation, but its efficiency is relatively low, especially for small droplets or high-velocity mixtures. Centrifugal separation accelerates separation through centrifugal force generated by high-speed rotation, achieving high efficiency, but the equipment is complex, energy-intensive, and has high maintenance costs. Filtration separation intercepts droplets through filters, but the filters are prone to clogging and require frequent replacement. Membrane separation technology is highly efficient and precise, but it is costly, prone to contamination, and has limited applicability. Furthermore, traditional gas-liquid separation devices typically suffer from complex structures, large footprints, low separation efficiency, and difficult maintenance. For example, while multi-stage separation structures improve efficiency, the equipment is bulky; complex mechanical structures, while efficient, are costly, energy-intensive, and prone to failure. Therefore, there is an urgent need for a gas-liquid separation device that is simple in structure, has high separation efficiency, is easy to maintain, and has a wide range of applications.

[0020] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

When a component is referred to as being "connected to" another component, it can be directly or indirectly connected to that other component. This "connection" is not limited to a fixed connection or a movable connection; the specific connection method should be determined based on the specific technical problem to be solved.

[0022] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0024] Example:

[0025] A screen-type gas-liquid separator includes a separation tank with a drain port 141 at the bottom and an exhaust port 121 at the top. It also includes a feed pipe 15 located within the tank and having an outlet. The tank is filled with a mesh packing material 11, positioned below the outlet. The gas-liquid mixture exiting the outlet enters the mesh packing material 11 under gravity. Small droplets converge into larger droplets within the mesh packing material 11 and move downwards under gravity until they reach the bottom of the tank, where they are discharged through the drain port 141. Gas detaches from the droplets, rises, and exits the mesh packing material 11, converging at the top of the tank and being discharged through the exhaust port 121. The mesh packing material 11 provides a large number of collision surfaces, promoting rapid convergence of small droplets into larger droplets, significantly improving gas-liquid separation efficiency. Simultaneously, the mesh packing material 11 extends the droplet residence time, allowing sufficient time for the gas to separate from the liquid. This device consists of only basic components such as a separation tank, a mesh packing material 11, and a feed pipe 15. It has a compact structure and is easy to manufacture and install. Separation is achieved by gravity, requiring no additional power, resulting in stable operation and low energy consumption. The mesh packing material 11 is removable for cleaning or replacement, leading to low maintenance costs and a long service life.

[0026] like Figure 1 As shown, in one possible embodiment, a partition plate 13 is further included; the partition plate 13 is disposed within the separation tank, dividing the separation tank into multiple filling units; the mesh filler 11 is located within the multiple filling units; the partition plate 13 is provided with multiple drain ports 131. Optionally, the drain ports 131 are disposed along the edge of the tank body of the partition plate 13; alternatively, the drain ports 131 are uniformly disposed on the partition plate 13. The partition plate 13 divides the separation tank into multiple filling units, allowing the gas-liquid mixture to be separated step-by-step within multiple units, extending the separation path and improving separation efficiency. The drain ports 131 provided on the partition plate 13 allow liquid to seep evenly to the next layer, preventing liquid from concentrating in a certain area and ensuring a more stable and efficient separation process. The partition plate 13 divides the mesh filler 11 into multiple units, facilitating segmented cleaning or replacement of the filler, reducing maintenance difficulty and cost.

[0027] In one possible embodiment, the separation tank includes a gas collecting hood 12, a liquid collecting tank 14, and a separation cylinder 10; the gas collecting hood 12 is detachably mounted above the separation cylinder 10, and an exhaust port 121 is located at the top of the gas collecting hood 12; the liquid collecting tank 14 is detachably mounted at the bottom of the separation cylinder 10, and a drain port 141 is located below the liquid collecting tank. Optionally, the gas collecting hood 12 and the liquid collecting tank 14 are connected to the separation cylinder 10 via flanges; a sealing ring is provided between the flanges. Optionally, the interfaces of the gas collecting hood 12, the separation cylinder 10, and the liquid collecting tank 14 are threaded and connected by rotating and tightening; polytetrafluoroethylene raw material tape is wrapped around the thread surface or anaerobic sealant is applied; a flat sealing surface is provided at the end of the thread, which is then pressed together with a rubber gasket or a metal washer. The detachable gas collection hood 12, separation cylinder 10, and liquid collection tank 14, with flange or threaded connections, enable modular assembly and maintenance, significantly improving the ease of installation and maintenance efficiency of the equipment. The sealing measures, such as the sealing ring in the flange connection or the PTFE raw material tape and anaerobic sealant in the threaded connection, ensure the airtightness and liquid tightness between the components, effectively preventing gas and liquid leakage.

[0028] Preferred, such as Figure 2 As shown, the mesh packing 11 includes multiple layers of packing mesh 4; the packing mesh 4 is a mesh structure formed by the cross intersection of warp threads 41 and weft threads 42; the multiple layers of packing mesh 4 are staggered. Liquid adheres to the warp threads 41 and weft threads 42, and converges into large droplets at the intersection. The staggered arrangement of the multiple layers of packing mesh 4 extends the flow path of the gas-liquid mixture, increases the chance of droplet collision and convergence, and further improves the separation efficiency. The packing mesh 4, formed by the cross intersection of warp threads 41 and weft threads 42, has a simple structure, low manufacturing cost, and is easy to mass-produce. Optionally, the multiple warp threads 41 and multiple weft threads 42 form multiple small squares, the width of which is 0.2-0.5 mm. The width of the squares meets the conditions for liquid convergence, while leaving sufficient channels for gas to rise.

[0029] like Figure 4 As shown, in one possible embodiment, a venting well 2 is provided inside the separation tank. The venting well 2 is vertically positioned in the middle of the separation tank and is fitted with a mesh packing material 11 and a partition plate 13. The venting well 2 includes a well wall 21, which is made of a porous hydrophobic material. Optionally, the well wall 21 is made of one of polytetrafluoroethylene, polypropylene, or polyethylene. The porous hydrophobic material allows gas to pass through but blocks liquid, enabling the gas in the filling unit to collect in the venting well 2 and rise along the venting well 2 to the top of the tank for discharge. The mesh packing material 11 and partition plate 13 inserted into the venting well 2 provide a concentrated upward channel for the gas, reducing the residence time of the gas in the packing material and improving the gas separation efficiency. The hydrophobic properties of the porous hydrophobic material effectively prevent liquid from entering the venting well 2, ensuring unobstructed gas flow.

[0030] Preferably, the filling unit is provided with multiple annular gaskets 5; the size of the annular gaskets 5 is adapted to the inner diameter of the separation tank; the filling mesh 4 is disposed between the annular gaskets 5. The annular gaskets 5, through their annular structure matching the inner diameter of the separation tank, fix and compress the multiple layers of filling mesh 4, while simultaneously forming uniform gaps between adjacent filling meshes 4. These gaps provide a directional flow channel for the gas, allowing it to quickly converge towards the central ventilation well 2, reducing the flow resistance of the gas in the filling mesh 4; at the same time, the compressive effect of the annular gaskets 5 prevents the filling mesh 4 from deforming or displacing due to airflow impact or liquid load, ensuring the long-term stability of the separation structure.

[0031] Preferably, the mesh filler 11 is made of a hydrophilic material. The hydrophilic material is one or more of cotton fiber, bamboo fiber, polyacrylate, and polyvinyl alcohol. Hydrophilic materials (such as cotton fiber and polyacrylate) form hydrogen bonds with water molecules through polar groups such as hydroxyl and carboxyl groups on their molecular chains, significantly enhancing droplet adsorption capacity. Simultaneously, the microporous structure on the material surface accelerates the aggregation of small droplets into larger droplets through capillary effect. When a gas-liquid mixture flows through the filler, the hydrophilic surface preferentially adsorbs the liquid, forming a continuous liquid film or droplet aggregate, while the gas rises due to density differences, achieving efficient gas-liquid separation.

[0032] Preferably, a demister 3 is provided at the top of the separation tank. Optionally, the demister 3 is located inside the gas collection hood 12. The demister 3 preferably uses a multi-layered woven mesh to physically intercept foam in the rising gas. The surface tension of the mesh breaks up the foam through the surface tension effect of the liquid film, causing tiny bubbles to coalesce into large droplets; at the same time, the high specific surface area of ​​the mesh increases the collision probability, forcing the droplets after the foam breaks to fall back to the mesh filler 11 for further gas separation.

[0033] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
