Description

Technical Field

[0001] The present invention belongs to the technical field of gas-liquid separation, and particularly relates to a high-efficiency gas-liquid separation device. Background Art

[0002] In industrial fields such as energy, chemical industry, petroleum, natural gas, food and beverage, and pharmaceuticals, gas-liquid separation devices are an important part of ensuring production efficiency, product purity, and equipment safety. During the gas-liquid separation process, steam-water separation devices are widely used in various processes to remove liquid droplets, impurities, and even aerosols from gases. These devices can effectively improve product quality, prevent equipment corrosion, and ensure the stability of the process flow.

[0003] Currently, common steam-water separation equipment includes gravity settlers, cyclone separators, corrugated plate separators, and wire mesh demisters, etc. The gravity settler realizes gas-liquid separation by relying on the action of gravity. The liquid settles and accumulates under the action of gravity, while the gas rises and is discharged. This method is suitable for capturing larger-sized liquid droplets, has a relatively simple structure, and low operating costs. However, for fine liquid droplets, especially those with a diameter less than 50 micrometers, the separation efficiency significantly decreases. In addition, the gravity settler has a large volume and is not suitable for occasions with limited space or high requirements for separation efficiency. The cyclone separator uses the centrifugal force generated by high-speed rotating airflow to separate the liquid from the gas, and is suitable for capturing larger-sized liquid droplets. However, its high airflow velocity also brings significant energy consumption, and the separation efficiency is unstable under low flow velocity or low liquid content conditions.

[0004] The corrugated plate separator realizes the capture of liquid droplets through a specific wavy structure design, which enables the airflow and liquid droplets to repeatedly impact and adhere to the plate surface. The larger liquid droplets adhere to the corrugated plate surface and flow down along the liquid film, thus separating from the gas. Due to its simple and compact structure and good separation effect, the corrugated plate separator is widely used in various industries. However, in the case of high flow velocity or a large number of fine liquid droplets, the separation efficiency of the corrugated plate is still not ideal, and its adaptability to flow velocity is poor. The wire mesh demister uses the high specific surface area of the wire mesh to capture liquid droplets in the airflow. The liquid droplets aggregate into larger particles on the wire mesh surface and then sink. The wire mesh demister has a better effect under low flow velocity conditions. However, the wire mesh is easily blocked by small liquid droplets, resulting in an increase in pressure drop, making it difficult to maintain a good separation effect for a long time. Moreover, liquid droplet remixing is likely to occur at high flow velocities, reducing the separation efficiency.

[0005] As can be seen from the above analysis, the existing corrugated plate and wire mesh demisting devices have the following problems in practical applications: First, the separation efficiency is not stable enough. Especially when facing smaller droplets or higher gas flow velocities, there are often phenomena such as re-entrainment of droplets and incomplete separation. Second, with the increase in the number of separation layers and the number of times of flow diversion, the complexity of the equipment structure and the manufacturing cost increase significantly, which is not conducive to popularization in industrial applications. In addition, high gas flow velocities often cause droplets to be entrained in the gas flow, resulting in re-mixing of gas and liquid and reducing the separation efficiency. The wire mesh demisting device is easily blocked by droplets during use, resulting in an increase in pressure drop, affecting the separation effect and increasing the maintenance cost at the same time. Therefore, there is room for improvement in the reliability, stability, and operating cost of the existing steam-water separation equipment. Summary of the Invention

[0006] In view of the deficiencies of the existing corrugated plate separators and wire mesh demisters, the present invention proposes an efficient gas-liquid separation device that organically combines the droplet capture of the corrugated plate and the filtering function of the wire mesh. The corrugated plate is used to disturb the gas-liquid mixture, so that the droplets adhere to form a liquid film and flow downward; while the wire mesh further filters the impurities in the liquid and effectively captures fine droplets to ensure the purity of the gas. Through this dual separation structure, the present invention has been significantly improved in terms of gas-liquid separation effect, equipment maintenance cost, and stability.

[0008] Further, after the gas-liquid mixture enters the central chamber through the air inlet channel, it enters the corrugated plate channel from the circumferential inlet of the central chamber for primary gas-liquid separation. The gas-liquid mixture after primary gas-liquid separation flows out from the outlet of the corrugated plate channel, enters the gas space of the drain pan downward from the space between the inner side plate and the outer side plate, and then passes upward through the wire mesh for secondary gas-liquid separation. The gas passing through the wire mesh finally exits from the upper end outlet of the gas guide cover.

[0009] Further, there are multiple sets of the corrugated plate channels, which are evenly arranged circumferentially around the central chamber; two sets of corrugated plates are provided inside the corrugated plate channels, and the two sets of corrugated plates are vertically arranged perpendicular to the flow direction of the gas-liquid mixture, and are parallel to each other and maintain a spacing. A gas-liquid mixture channel is formed between the two sets of corrugated plates, and the upper ends of the two sets of corrugated plates are both connected to the bottom surface of the upper cover plate of the corrugated plate channel.

[0010] Further, the gas-liquid mixture channel between the two sets of corrugated plates includes multiple sub-channels, and there is a certain angle between adjacent two sub-channels. Water diversion grooves are formed on the wall surface of the corrugated plate on the left or right side of each sub-channel, and the water diversion grooves on adjacent two sub-channels are located on the corrugated plates on different sides; micro-grooves with a corrugated structure are provided on the inner and outer wall surfaces of the water diversion grooves.

[0011] Further, the water diversion groove is integrally strip-shaped, and the water diversion groove is divided into multiple independent unit partition grooves in the long side direction by partition plates inside the water diversion groove. Two sets of V-shaped structures are provided in each independent unit partition groove, and the first V-shaped structure is located above the second V-shaped structure; the tip of the first V-shaped structure faces upward, and there are gaps between the left and right ends and the second V-shaped structure; the tip of the second V-shaped structure faces downward, and a water drainage port of the water diversion groove is opened at the tip.

[0012] Further, the length of the long side of the water diversion groove is consistent with the straight-line distance from the inlet to the outlet of the corrugated plate channel, the height of the partition plate is 80% to 100% of the depth of the water diversion groove, and the spacing of the partition plates is 50% to 70% of the length of the short side of the water diversion groove.

[0013] Further, the hydrophobic tray includes a liquid collecting tank and a hydrophobic pipe; the liquid collecting tank is integrally in a funnel-shaped structure, and the liquid collecting tank is connected to the outer surrounding plate; the hydrophobic pipe is connected to the central outlet of the funnel-shaped structure of the liquid collecting tank; the air inlet channel passes through the hydrophobic pipe; the water drainage ports of the independent unit partition grooves in the water diversion groove are communicated with the liquid collecting tank through drain pipes, and all the drain pipes are arranged parallel to each other.

[0014] Further, the wire mesh is made of a high-strength corrosion-resistant metal wire material, and the wire mesh is a multi-layer structure, which is laminated and laid in all the void areas between the inner surrounding plate and the central chamber.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1) Compact structure and higher separation efficiency. The present invention integrates the dual separation structures of corrugated plates and wire meshes and adopts an efficient and compact structure design, achieving efficient step-by-step separation of liquid droplets of different sizes in the airflow. The corrugated plate with micro-groove design is responsible for the preliminary separation of larger liquid droplets, and the wire mesh further captures the remaining fine liquid droplets. This combined design not only greatly improves the overall separation efficiency but also greatly enriches the application scenarios and installation convenience of the device due to its compactness.

[0017] 2) Stronger stability. In the traditional corrugated plate structure, when the airflow velocity is high or the gas humidity is large, it is easy to cause re-mixing of gas and liquid or secondary entrainment of liquid droplets due to the rupture of the liquid film. The present invention designs a corrugated plate with a micro-groove structure. The micro-grooves provide more contact surfaces, making it easier for the liquid droplets in the gas-liquid two-phase flow to adhere and be collected, enhancing the liquid droplet capture effect of the corrugated plate. The captured small liquid droplets flow downward along the micro-grooves into the drainage trough, effectively avoiding the long-term retention of small liquid droplets on the surface of the corrugated plate, thereby effectively reducing the possibility of secondary entrainment of small liquid droplets.

[0018] 3) Better anti-interference and anti-short-circuit capabilities. The drainage trough of the present invention is designed in a long strip V shape. This structure is conducive to guiding the liquid to converge towards the center of the drainage trough and flow towards the drainage outlet of the drainage trough. At the same time, it is divided into multiple independent unit separation troughs by arranging multiple partition plates inside, blocking the direct action of the airflow on the liquid droplets, preventing the liquid droplets from being rolled up or entrained by the airflow during the convergence process, thereby ensuring that the liquid can be discharged stably and smoothly, avoiding the accumulation of liquid in the drainage trough, improving the liquid collection efficiency and preventing airflow short-circuit.

[0019] 4) Richer flexibility and scenario adaptability. In the present invention, the specific structural parameters and layout forms of the corrugated plate and wire mesh can be flexibly selected and adjusted according to the specific application requirements, showing good applicability and flexibility to user needs.

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] Aiming at the deficiencies of the existing corrugated plate separators and wire mesh demisters, the present invention proposes an efficient gas-liquid separation device that combines corrugated plates and wire meshes, organically integrating the droplet capture of corrugated plates and the filtering effect of wire meshes. The corrugated plates are used to disturb the gas-liquid mixture, causing droplets to adhere and form liquid films that flow downward, while the wire mesh further filters impurities in the liquid and effectively captures fine droplets to ensure the purity of the gas. Through this dual separation structure, the present invention has been significantly improved in terms of gas-liquid separation effect, equipment maintenance cost, and stability. The device can maintain a high separation efficiency at different air flow rates and liquid contents, reduce the risk of gas-liquid remixing, and through reasonable corrugated plate and wire mesh designs, reduce the possibility of wire mesh blockage, extend the service life of the equipment, and reduce the maintenance frequency. The present invention effectively solves the problems existing in the prior art, such as unstable separation effect, gas-liquid remixing, and large equipment volume, and provides a solution with a simple structure, remarkable separation effect, and low cost for steam-water separation.

[0029] As Figures 1 to 7 shown, an efficient gas-liquid separation device includes a gas guide cover 1, a fixed skeleton, an air inlet channel 2-1, a central chamber 2-2, an upper cover plate 2-3 of the central chamber, an upper cover plate 2-4 of the corrugated plate channel, a support bottom plate 2-5 of the drain groove, a drain pipe 2-6, a wire mesh placement rack 2-7, an inner side plate 2-8, an outer side plate 2-9, a drain groove 3, a partition plate 3-1, a drain outlet 3-2 of the drain groove, a corrugated plate 4, a micro groove 4-1, a wire mesh 5, a hydrophobic tray 6, a liquid collection tank 6-1, and a drain pipe 6-2.

[0030] The gas guide cover 1 is arranged at the top, and the hydrophobic tray 6 is arranged at the bottom. The two are connected by the outer side plate 2-9; the upper ends of the inner side plate 2-8 and the outer side plate 2-9 are connected by a cover plate, and there is a space between the inner side plate 2-8 and the outer side plate 2-9. There is a space between the lower end of the inner side plate 2-8 and the hydrophobic tray 6; the upper end of the air inlet channel 2-1 passes through the hydrophobic tray 6 and is connected to the bottom of the central chamber 2-2. The upper end of the central chamber 2-2 is provided with an upper cover plate 2-3 of the central chamber. A corrugated plate channel and a wire mesh 5 are provided between the central chamber 2-2 and the inner side plate 2-8; the inlet of the corrugated plate channel is circumferentially connected to the central chamber 2-2. The top of the corrugated plate channel is provided with an upper cover plate 2-4 of the corrugated plate channel, and the bottom is provided with a drain groove 3. The outlet of the corrugated plate channel communicates with the space between the inner side plate 2-8 and the outer side plate 2-9.

[0031] There are multiple corrugated plate channels, which are circumferentially and uniformly arranged around the central chamber for 2 - 2 turns; there are two groups of corrugated plates 4 inside the corrugated plate channels. The two groups of corrugated plates are vertically arranged facing the flow direction of the gas - liquid mixture, and are parallel to each other and maintain a spacing. The space between the two groups of corrugated plates forms a gas - liquid mixture channel. The upper ends of the two groups of corrugated plates are both connected to the bottom surface of the upper cover plate 2 - 4 of the corrugated plate channel. The gas - liquid mixture channel between the two groups of corrugated plates includes multiple sub - channels. There is a certain angle between adjacent two sub - channels. Water - conveying grooves are opened on the wall surface of the corrugated plate 4 on the left or right side of each sub - channel, and the water - conveying grooves on adjacent two sub - channels are located on the corrugated plates 4 on different sides; micro - grooves 4 - 1 with a corrugated structure are provided on the inner and outer wall surfaces of the water - conveying grooves.

[0032] The water - draining groove 3 is integrally strip - shaped. Inside the water - draining groove 3, the water - draining groove 3 is divided into multiple independent unit dividing grooves in the long - side direction by a partition plate 3 - 1. There are two groups of V - shaped structures in each independent unit dividing groove. The first V - shaped structure is located above the second V - shaped structure; the tip of the first V - shaped structure faces upward, and there are gaps between the left and right ends and the second V - shaped structure; the tip of the second V - shaped structure faces downward, and a water - draining port 3 - 2 of the water - draining groove is opened at the tip. The length of the long side of the water - draining groove 3 is the same as the straight - line distance from the inlet to the outlet of the corrugated plate channel. The height of the partition plate 3 - 1 is 80% - 100% of the depth of the water - draining groove 3, and the spacing of the partition plate 3 - 1 is 50% - 70% of the length of the short side of the water - draining groove 3.

[0033] The water - draining tray 6 includes a liquid - collecting tank 6 - 1 and a water - draining pipe 6 - 2; the liquid - collecting tank 6 - 1 is integrally in a funnel - shaped structure, and the liquid - collecting tank 6 - 1 is connected to the outer enclosing plate 2 - 9; the water - draining pipe 6 - 2 is connected to the central outlet of the funnel - shaped structure of the liquid - collecting tank 6 - 1; the air - inlet channel 2 - 1 passes through the water - draining pipe 6 - 2; the water - draining ports 3 - 2 of the independent unit dividing grooves in the water - draining groove 3 are communicated to the liquid - collecting tank 6 - 1 through a drain pipe 2 - 6, and all the drain pipes 2 - 6 are arranged parallel to each other.

[0034] After the gas - liquid mixture enters the central chamber 2 - 2 through the air - inlet channel 2 - 1, it enters the corrugated plate channel from the circumferential inlet of the central chamber 2 - 2 for primary gas - liquid separation. The gas - liquid mixture after primary gas - liquid separation flows out from the outlet of the corrugated plate channel, enters the gas space of the water - draining tray 6 downward from the space between the inner enclosing plate 2 - 8 and the outer enclosing plate 2 - 9, and then undergoes secondary gas - liquid separation upward through the wire mesh 5. The gas passing through the wire mesh 5 finally discharges from the upper - end outlet of the gas flow - guiding cover 1.

[0035] As Figure 1As shown, the gas deflector 1 is located at the top of the device and is the last component before the gas is discharged. Its main function is to guide the gas that has been secondarily separated by the wire mesh 5 to flow outwards. The gas deflector 1 adopts a conical geometric design to achieve a full rectification effect on the gas before it leaves the separation device, enabling the gas to be discharged from the device stably and evenly.

[0036] As Figure 2 and Figure 3 shown, the overall skeleton of the high-efficiency gas-liquid separation device can adopt a regular octagon as the core support structure of the entire device. It not only provides stable support but also ensures the reasonable and stable arrangement of each component (the drain tank 3, the corrugated plate 4, the wire mesh 5). The regular octagon skeleton adopts a double-layer design. The intake pipe 2-1 is connected to the central chamber 2-2, and the central chamber 2-2 is connected to the gas channel between the inner enclosing plate 2-8 and the outer enclosing plate 2-9 through 8 groups of corrugated plate channels, facilitating the gas separated by the corrugated plate to enter the wire mesh 5 area from the lower channel. The regular octagon skeleton is reasonably designed, which is convenient for the installation and maintenance of the equipment. At the same time, it enhances the seismic resistance of the equipment at high gas flow velocities, ensuring the structural stability and safety of the entire separation device during operation. The corrugated plate 4 is an important component for achieving primary steam-water separation. Its installation position is on the cross-shaped structure of the regular octagon fixed skeleton, forming a uniformly distributed primary separation area.

[0037] As Figure 4 shown, the corrugated plate design of the present invention has been innovated in structure. Micro-grooves 4-1 are added on the basis of the water trough of the existing corrugated plate 4. The micro-grooves 4-1 are designed in a corrugated structure to improve the ability of liquid aggregation and discharge during the steam-water separation process. The specific parameters include the groove depth d, the spacing S, and the inclination angle . The micro-grooves 4-1 enable the liquid droplets in the gas-liquid two-phase flow to be more easily attached and collected by providing more contact surfaces, enhancing the droplet capture effect of the corrugated plate. The captured small liquid droplets flow down along the micro-grooves 4-1 into the drain tank 3, effectively avoiding the long-term retention of small liquid droplets on the surface of the corrugated plate 4, thereby effectively reducing the possibility of secondary entrainment of small liquid droplets. The micro-groove design can be adjusted according to different working conditions to meet the separation requirements of different industries and processes, reflecting high flexibility and application value.

[0038] The efficiency of the corrugated plate in capturing liquid droplets can be characterized by the following formula: where the capture coefficient , is the liquid droplet attachment factor, A is the effective contact area of the corrugated plate surface, C d is the liquid droplet drag coefficient, and Q g is the gas volume flow rate. After introducing the micro-grooves 4-1, the effective contact area A of the corrugated plate 4 surface is significantly increased, and at the same time, the liquid droplet attachment factor is also optimized. This structure improves the droplet capture ability of the corrugated plate 4 by 10% - 20%, and can efficiently aggregate the tiny droplets in the air flow into larger droplets and guide the droplets to be discharged to the hydrophobic area. The flow velocity of the liquid on the surface of the corrugated plate 4 can be analyzed by the formula , where represents the density of the liquid, g represents the acceleration due to gravity, represents the dynamic viscosity of the liquid, and the inclination angle and the groove depth d of the corrugated plate 4 are key parameters. The optimized design can accelerate the liquid discharge speed and reduce the residence time of the liquid on the surface of the corrugated plate 4, thereby effectively avoiding the phenomenon of gas impacting the liquid film or droplets being entrained by the air flow for the second time. Tests show that this design can increase the liquid discharge speed by 15% - 25%, further ensuring the stability of the separation efficiency.

[0039] In the present invention, the structural design of the corrugated plate 4 has high flexibility. Specifically, parameters such as the depth d, spacing S, and inclination angle of the micro-grooves can be adjusted according to the working conditions. For example, for the air flow working conditions with high flow rate or high liquid content, deeper grooves and denser spacing can be selected to enhance the capture and discharge capabilities; while for the working conditions with low flow rate or low liquid content, the groove parameters can be adjusted to reduce the pressure drop loss. This flexibility makes the corrugated plate design have higher adaptability and application value in various industrial applications.

[0040] The present invention mainly provides the installation structure of the corrugated plate 4 and its layout design in the separation device. Specific corrugated plate parameters, such as the corrugation pattern, crest spacing, wave height, length, and width, can be adjusted according to the specific requirements of the application. In this way, users can flexibly select the specific size and style of the corrugated plate according to the gas flow rate, liquid content, and separation efficiency requirements of the processed gas. This design not only improves the adaptability of the device, but also enables the corrugated plate 4 structure to be easily replaced or adjusted under different working conditions to achieve the best separation effect, enhancing the flexibility and versatility of the device in industrial applications.

[0041] As Figure 5 shown, the hydrophobic trough 3 is placed below the corrugated plate 4, and its quantity is the same as that of the corrugated plate 4 units. The structure and layout of the hydrophobic trough 3 are optimized, and the overall design is a long strip V-shaped. This structure is conducive to guiding the liquid to converge towards the center of the hydrophobic trough 3 and flow towards the drain opening 3-2 of the hydrophobic trough. At the same time, multiple partition plates 3-1 are arranged inside it to divide it into multiple independent unit partition troughs, blocking the direct action of the air flow on the droplets and preventing the droplets from being rolled up or entrained by the air flow during the convergence process, so as to ensure that the liquid can be stably and smoothly discharged, avoid the accumulation of liquid in the hydrophobic trough 3, improve the liquid collection efficiency, and prevent the air flow from short-circuiting.

[0042] The length of the long side of the water drainage groove 3 is consistent with the straight-line distance of the corrugated plate channel from the inlet to the outlet. The water drainage port 3-2 of the water drainage groove is connected to the drain pipe 2-6, and its function is to collect the small liquid droplets separated by the corrugated plate 4 and smoothly discharge them into the liquid collecting tank 6-1. The height of the partition plate 3-1 is related to the depth of the water drainage groove 3, and its height range is 80% to 100% of the depth of the water drainage groove 3. At the same time, the spacing of the partition plate 3-1 is preferably 50% to 70% of the width of the water drainage groove 3. To further improve the discharge efficiency, the V-shaped structure at the bottom of the water drainage groove 3 guides the liquid to flow towards the water drainage port 3-2 of the water drainage groove, and the liquid is guided to the external liquid discharge system through the drain pipe 2-6. The diameter D of the drainage port o needs to ensure that the liquid can be quickly discharged to avoid liquid retention, and its design is based on the calculation of the relationship between the liquid discharge flow velocity v l and the flow rate Q: . This optimized design ensures that the liquid can be discharged stably and continuously, avoiding problems such as liquid backflow or retention caused by poor drainage. By optimizing the length of the water drainage groove 3, the size and spacing of the partition plate 3-1, and the design parameters of the water drainage port 3-2 of the water drainage groove, the entire hydrophobic system shows higher efficiency and stability in liquid collection and discharge, providing a reliable guarantee for the overall separation performance of the equipment.

[0043] The wire mesh 5 is the secondary separation component in the present invention. Its installation position is in the gap of the cross-shaped structure of the regular octagon fixed skeleton, forming a uniformly distributed secondary separation area. The high specific surface area design of the wire mesh enables it to effectively capture the fine liquid droplets and tiny impurity particles remaining in the gas. The gas preliminarily separated by the corrugated plate 4 enters the secondary separation area where the wire mesh 5 is located to capture the fine liquid droplets again, causing them to aggregate and merge into larger liquid droplets on the wire mesh, and further settling by gravity to the hydrophobic tray 6. The material of the wire mesh is generally high-strength corrosion-resistant metal wires, which are finely woven to form a multi-layer structure. This design not only ensures the smoothness of the air flow channel but also fully improves the liquid droplet capture efficiency. To enhance the versatility and adaptability of the equipment, the structural design of the wire mesh has a high degree of flexibility. Specifically, the shape, material, and number of layers of the wire mesh can be customized according to the user's needs and specific application scenarios.

[0044] The hydrophobic tray 6 is connected to the external liquid discharge system and consists of a liquid collecting tank 6-1 and a drain pipe 6-2, ensuring that the liquid collected in the liquid collecting tank 6-1 can be efficiently and stably discharged through the drain pipe 6-2 to prevent liquid accumulation inside the device.

[0045] Such as Figure 7As shown, the gas material containing droplets (or aerosols, etc.) first enters the central chamber 2-2 from the air inlet channel 2-1 at the bottom of the device. The central chamber 2-2 is connected to the channels of 8 groups of corrugated plates 4, and the gas enters the channels of the corrugated plates 4 for primary separation. The corrugated plates 4 cause the high-speed flowing gas to turn and collide through their corrugated structure, thereby capturing larger droplets, causing them to aggregate and flow downward along the surface of the corrugated plates, and finally converge into the drain trough 3 below the corrugated plates 4 and be discharged.

[0046] The gas after primary separation flows out from the end of the corrugated plate 4, turns downward and enters the gas space in the hydrophobic tray 6, then turns back upward and flows into the wire mesh 5 for secondary separation, capturing fine droplets again, causing them to aggregate and merge into larger droplets on the wire mesh, and further settling by gravity into the hydrophobic tray 6. The clean gas after being processed by the wire mesh 5 is finally discharged through the flow guide cover.

[0047] The present invention combines corrugated plates and wire meshes, and is equipped with an optimized drainage structure below the wire mesh to achieve an efficient gas-liquid separation effect. The present invention aims to solve common problems in existing gas-liquid separation devices such as droplet entrainment, unstable separation effect, and gas-liquid secondary mixing, and improve the separation efficiency and stability of the device. Through the combination of corrugated plates and wire meshes, the present invention captures large particles and fine droplets to achieve comprehensive gas-liquid separation; adopts a V-shaped drainage structure to quickly discharge the separated liquid, preventing liquid retention and re-entrainment by high-speed gas flow; and through optimized structural layout and the use of corrosion-resistant materials, enhances the stability and durability of the device under working conditions such as high humidity and high gas flow velocity. At the same time, the V-shaped drainage design ensures the smooth drainage process, prevents blockage and liquid accumulation, and ensures the continuous and efficient operation of the device. In addition, the present invention provides a flexible structural design, allowing adjustment of structural parameters and layout forms according to actual application requirements to adapt to different working conditions. In summary, the present invention provides a highly efficient, stable, and structurally compact gas-liquid separation device, which is applicable to industrial fields such as petrochemical, chemical, and pharmaceutical industries that require gas-liquid separation.
