Description
Technical Field
[0001] The invention belongs to the technical field of gas-liquid separation, and in particular relates to a high-efficiency gas-liquid separation device. Background Art
[0002] In the energy, chemical, petroleum, natural gas, food and beverage, and pharmaceutical industries, gas-liquid separation devices are an important part of ensuring production efficiency, product purity, and equipment safety. In the gas-liquid separation process, gas-water separation devices are widely used in various processes to remove droplets and impurities, and even aerosols, from the gas. These devices can effectively improve product quality, prevent equipment corrosion, and ensure the stability of the process.
[0003] At present, common gas-water separation equipment includes gravity settlers, cyclone separators, corrugated plate separators and wire mesh demisters. Gravity settlers rely on gravity to achieve gas-liquid separation. The liquid settles and collects under the action of gravity, while the gas rises and is discharged. This method is suitable for capturing larger droplets, with a relatively simple structure and low operating cost, but the separation efficiency is significantly reduced for small droplets, especially those with a diameter of less than 50 microns. In addition, the gravity settler is large in size 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 liquid from gas, which is suitable for capturing larger droplets, but its high airflow velocity also brings significant energy consumption, and the separation efficiency is unstable when the flow rate is low or the liquid content is low.
[0004] The corrugated plate separator uses a specific wavy structure design to make the airflow and droplets repeatedly collide and adhere on the plate surface, thereby achieving the capture of droplets. After the larger droplets adhere to the surface of the corrugated plate, they flow down along the liquid film and are separated from the gas. The corrugated plate separator is widely used in various industries due to its simple and compact structure and good separation effect. However, in the case of high flow rate or a large number of fine droplets, the separation efficiency of the corrugated plate is still not ideal, and the adaptability to the flow rate is poor. The wire mesh demister uses the high specific surface area of the wire mesh to capture droplets in the airflow. The droplets gather into larger particles on the surface of the wire mesh and then sink. The wire mesh demister works better under lower flow rate conditions, but the wire mesh is easily blocked by small droplets, resulting in an increase in pressure drop, making it difficult to maintain a good separation effect for a long time. In addition, droplets are prone to remixing at high flow rates, reducing the separation efficiency.
[0005] From the above analysis, it can be seen that the existing corrugated plate and wire mesh defoaming devices have the following problems in practical applications: First, the separation efficiency is not stable enough, especially when facing smaller droplets or higher air flow velocities, the droplets are often re-entrained and the separation is not thorough. Secondly, with the increase in the number of separation layers and the number of diversions, the complexity of the equipment structure and the manufacturing cost are significantly increased, which is not convenient for promotion in industrial occasions. In addition, high air flow velocities often cause droplets to be entrained in the air flow, and then the gas and liquid are remixed, reducing the separation efficiency. The wire mesh defoaming device is easily blocked by droplets during use, resulting in an increase in pressure drop, which affects the separation effect and increases maintenance costs. Therefore, there is room for improvement in the reliability, stability and operating costs of existing gas-water separation equipment. Summary of the invention
[0006] In view of the shortcomings of existing corrugated plate separators and wire mesh demisters, the present invention proposes a highly efficient gas-liquid separation device, which 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 down; while the wire mesh further filters impurities in the liquid and effectively captures fine droplets to ensure gas purity.

[0008] Furthermore, after the gas-liquid mixture enters the central chamber through the air inlet channel, it enters the corrugated plate channel from the circumferential entrance of the central chamber for primary gas-liquid separation. The gas-liquid mixture after the primary gas-liquid separation flows out from the outlet of the corrugated plate channel, downwardly enters the gas space of the degassing disk from the space between the inner and outer enclosures, and then upwardly passes through the wire mesh for secondary gas-liquid separation. The gas passing through the wire mesh is finally discharged from the outlet at the upper end of the gas deflector.
[0009] Furthermore, there are multiple groups of corrugated plate channels, which are evenly arranged around the central chamber; two groups of corrugated plates are arranged inside the corrugated plate channel, and the two groups of corrugated plates are arranged vertically facing the flow direction of the gas-liquid mixture, and are parallel to each other and maintain a distance, and a gas-liquid mixture channel is formed between the two groups of corrugated plates, and the upper ends of the two groups of corrugated plates are connected to the bottom surface of the upper cover plate of the corrugated plate channel.
[0010] Furthermore, the gas-liquid mixture channel between the two groups of corrugated plates includes multiple sub-channels, and there is a certain angle between two adjacent sub-channels. A water trough is opened on the wall of the left or right corrugated plate of each sub-channel, and the water troughs on the two adjacent sub-channels are located on different side corrugated plates; micro-grooves with a corrugated structure are provided on the inner and outer wall surfaces of the water trough.
[0011] Furthermore, the drain groove is overall in the shape of a long strip, and is divided into a plurality of independent unit separation grooves in the long side direction by a partition plate inside the drain groove, and each independent unit separation groove is provided with two groups of V-shaped structures, 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 is a gap between the left and right ends and the second V-shaped structure; the tip of the second V-shaped structure faces downward, and a drain outlet of the drain groove is opened at the tip.
[0012] Furthermore, the length of the long side of the drain groove is consistent with the straight-line distance from the entrance to the exit of the corrugated plate channel, the height of the partition plate is 80% to 100% of the depth of the drain groove, and the spacing between the partition plates is 50% to 70% of the length of the short side of the drain groove.
[0013] Furthermore, the drain pan includes a liquid collecting trough and a drain pipe; the liquid collecting trough is a funnel-shaped structure as a whole, and the liquid collecting trough is connected to the outer enclosure; the drain pipe is connected to the central outlet of the funnel-shaped structure of the liquid collecting trough; the air intake channel passes through the drain pipe; the drain outlet of each independent unit separation trough in the drain trough is connected to the liquid collecting trough through a drain pipe, and all the drain pipes are arranged parallel to each other.
[0014] Furthermore, the wire mesh is made of high-strength corrosion-resistant metal wire material, and the wire mesh has a multi-layer structure and is stacked and laid in all gap areas between the inner side panel and the central cavity.
[0015] The beneficial effects of the present invention are:
[0016] 1) Compact structure and higher separation efficiency. The present invention integrates the dual separation structure of the corrugated plate and the wire mesh and adopts an efficient and compact structural design, which realizes efficient step-by-step separation of droplets of different sizes in the airflow. The corrugated plate with micro-groove design is responsible for the initial separation of larger droplets, and the wire mesh further captures the remaining fine droplets. This combined design greatly improves the overall separation efficiency, and the compactness of the device also greatly enriches its application scenarios and the convenience of installation.
[0017] 2) Stronger stability. The traditional corrugated plate structure is prone to gas-liquid remixing or liquid film rupture and secondary entrainment of droplets when the gas flow rate is high or the gas humidity is high. The present invention designs a corrugated plate with a micro-groove structure. The micro-grooves provide more contact surfaces, making it easier for droplets in the gas-liquid two-phase flow to adhere and collect, thereby enhancing the droplet capture effect of the corrugated plate. The captured small droplets flow down along the micro-grooves into the hydrophobic grooves, effectively avoiding the long-term retention of small droplets on the surface of the corrugated plate, thereby effectively reducing the possibility of secondary entrainment of small droplets.
[0018] 3) Better anti-interference and anti-short circuit capabilities. The hydrophobic groove of the present invention is designed in a long V-shaped structure, which is conducive to guiding the liquid to gather to the center of the hydrophobic groove and flow to the drain outlet of the hydrophobic groove. At the same time, it is divided into multiple independent unit separation grooves by arranging multiple partition plates inside, blocking the airflow from directly acting on the droplets, preventing the droplets from being rolled up or entrained by the airflow during the gathering process, thereby ensuring that the liquid can be discharged stably and smoothly, avoiding the accumulation of liquid in the hydrophobic groove, so as to improve the collection efficiency of the liquid and prevent the airflow from short-circuiting.
[0019] 4) More flexibility and scene adaptability. The specific structural parameters and layout of the corrugated plate and the screen in the present invention can be flexibly selected and adjusted according to the specific needs of the application, reflecting good user demand applicability and flexibility.

[0027] The present invention is further described below in conjunction with the accompanying drawings.
[0028] In view of the shortcomings of the existing corrugated plate separator and wire mesh demister, the present invention proposes a high-efficiency gas-liquid separation device that combines a corrugated plate and a wire mesh, and organically combines the droplet capture of the corrugated plate and the filtering effect 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 down, 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 significantly improved the gas-liquid separation effect, equipment maintenance cost and stability. The device can maintain a high separation efficiency at different air flow velocities and liquid contents, reduce the risk of gas-liquid remixing, and reduce the possibility of wire mesh clogging through reasonable corrugated plate and wire mesh design, extend the service life of the equipment, and reduce the maintenance frequency. The present invention effectively solves the problems of unstable separation effect, gas-liquid remixing, and bulky equipment in the prior art, and provides a solution for gas-water separation with a simple structure, significant separation effect and low cost.

[0030] The gas deflector 1 is arranged at the top and the drain pan 6 is arranged at the bottom, and the two are connected through the outer panel 2-9; the upper ends of the inner panel 2-8 and the outer panel 2-9 are connected through a cover plate, and a space is left between the inner panel 2-8 and the outer panel 2-9, and a space is left between the lower end of the inner panel 2-8 and the drain pan 6; the upper end of the air intake channel 2-1 passes through the drain pan 6 and is connected to the bottom of the central chamber 2-2, and a central chamber upper cover plate 2-3 is provided at the upper end of the central chamber 2-2, and a corrugated plate channel and a wire mesh 5 are provided between the central chamber 2-2 and the inner panel 2-8; the inlet of the corrugated plate channel is circumferentially connected to the central chamber 2-2, a corrugated plate channel upper cover plate 2-4 is provided on the top of the corrugated plate channel, and a drain groove 3 is provided at the bottom, and the outlet of the corrugated plate channel is connected to the space between the inner panel 2-8 and the outer panel 2-9.
[0031] There are multiple groups of corrugated plate channels, which are evenly arranged around the central chamber 2-2; two groups of corrugated plates 4 are arranged inside the corrugated plate channel, and the two groups of corrugated plates are arranged vertically facing the incoming flow direction of the gas-liquid mixture, and are parallel to each other and keep a distance, and a gas-liquid mixture channel is formed between the two groups of corrugated plates, and the upper ends of the two groups of corrugated plates are 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, and there is a certain angle between the adjacent sub-channels. A water delivery trough is opened on the wall surface of the corrugated plate 4 on the left or right side of each sub-channel, and the water delivery troughs on the adjacent sub-channels are located on different side corrugated plates 4; micro grooves 4-1 with corrugated structures are provided on the inner and outer wall surfaces of the water delivery trough.
[0032] The drain groove 3 is in the shape of a long strip as a whole. The drain groove 3 is divided into a plurality of independent unit separation grooves in the long side direction by a separation plate 3-1 inside the drain groove 3. Two groups of V-shaped structures are arranged in each independent unit separation 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 is a gap between the left and right ends and the second V-shaped structure. The tip of the second V-shaped structure faces downward, and a drain groove outlet 3-2 is provided at the tip. The length of the long side of the drain groove 3 is consistent with the straight-line distance from the entrance to the exit of the corrugated plate channel. The height of the separation plate 3-1 is 80% to 100% of the depth of the drain groove 3, and the spacing of the separation plates 3-1 is 50% to 70% of the length of the short side of the drain groove 3.
[0033] The drain pan 6 includes a liquid collecting tank 6-1 and a drain pipe 6-2; the liquid collecting tank 6-1 is a funnel-shaped structure as a whole, and the liquid collecting tank 6-1 is connected to the outer enclosure 2-9; the drain pipe 6-2 is connected to the central outlet of the funnel-shaped structure of the liquid collecting tank 6-1; the air intake channel 2-1 passes through the drain pipe 6-2; the drain tank drain outlet 3-2 of each independent unit separation tank in the drain tank 3 is connected to the liquid collecting tank 6-1 through the 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 entrance of the central chamber 2-2 for primary gas-liquid separation. The gas-liquid mixture after the primary gas-liquid separation flows out from the outlet of the corrugated plate channel, and downwardly enters the gas space of the hydrophobic disk 6 from the space between the inner enclosure 2-8 and the outer enclosure 2-9, and then upwardly passes through the wire mesh 5 for secondary gas-liquid separation. The gas passing through the wire mesh 5 is finally discharged from the upper outlet of the gas deflector 1.
[0035] like 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 to flow out after the secondary separation through the wire mesh 5. The gas deflector 1 adopts a conical geometric design, so that the gas can achieve a sufficient rectification effect before leaving the separation device, and can be discharged from the device stably and evenly.
[0036] like Figure 2 and Figure 3 As shown, the overall skeleton of the efficient gas-liquid separation device can adopt a regular octagon, which is 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 (drain groove 3, corrugated plate 4, wire mesh 5). The regular octagonal skeleton adopts a double-layer design. The air intake pipe 2-1 is connected to the central chamber 2-2. The central chamber 2-2 is connected to the gas channel between the inner side panel 2-8 and the outer side panel 2-9 through 8 sets of corrugated plate channels, so that the gas separated by the corrugated plate can enter the wire mesh 5 area from the lower channel. The regular octagonal 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 air flow speeds and ensures the structural stability and safety of the entire separation device during operation. The corrugated plate 4 is an important component for realizing primary gas-water separation. Its installation position is located on the M-shaped structure of the regular octagonal fixed skeleton, forming a uniformly distributed primary separation area.
[0037] like Figure 4 As shown, the corrugated plate design of the present invention is innovative in structure, and micro grooves 4-1 are added on the basis of the water delivery groove of the existing corrugated plate 4. The micro grooves 4-1 are designed as corrugated structures to improve the collection and discharge capacity of liquid during the steam-water separation process. The specific parameters include groove depth d, spacing S and inclination angle . The micro groove 4-1 provides more contact surface, making it easier for droplets in the gas-liquid two-phase flow to adhere and collect, thereby enhancing the droplet capture effect of the corrugated plate. The captured small droplets flow downward along the micro groove 4-1 into the hydrophobic groove 3, effectively avoiding the long-term retention of small droplets on the surface of the corrugated plate 4, thereby effectively reducing the possibility of secondary entrainment of small droplets. The micro groove design can be adjusted according to different working conditions to meet the separation needs of different industries and processes, reflecting high flexibility and application value.
[0038] The efficiency of the corrugated plate for droplet capture can be characterized by the following formula: The capture coefficient , is the droplet adhesion factor, A is the effective contact area of the corrugated plate surface, C d is the droplet drag coefficient, Q g is the gas volume flow rate. After the introduction of the micro grooves 4-1, the effective contact area A on the surface of the corrugated plate 4 is significantly increased, and the droplet attachment factor This structure increases the droplet collection capacity of the corrugated plate 4 by 10% to 20%, and can efficiently gather tiny droplets in the airflow into larger droplets, and guide the droplets to be discharged to the hydrophobic area. The flow rate of the liquid on the surface of the corrugated plate 4 is The formula can be To analyze, represents the density of the liquid, g represents the acceleration due to gravity, represents the dynamic viscosity of the liquid, the inclination angle of the corrugated plate 4 The optimized design can accelerate the liquid discharge speed and reduce the liquid residence time on the surface of the corrugated plate 4, thereby effectively avoiding the phenomenon of gas impacting the liquid film or liquid droplets being entrained by the airflow for the second time. Tests show that this design can increase the liquid discharge speed by 15% to 25%, further ensuring the stability of the separation efficiency.
[0039] The structural design of the corrugated plate 4 in the present invention is highly flexible. Specifically, the depth d, the spacing S, the inclination angle of the micro grooves Parameters such as the grooves can be adjusted according to the working conditions. For example, for airflow 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 conditions with low flow rate or low liquid content, the groove parameters can be adjusted to reduce pressure drop losses. This flexibility makes the corrugated plate design more adaptable and valuable in a variety of industrial applications.
[0040] The present invention mainly provides the installation structure of the corrugated plate 4 and its layout design in the separation device. The specific parameters of the corrugated plate, such as the waveform style, wave peak spacing, wave height, length and width, etc., can be adjusted according to the specific needs of the application. In this way, the user can flexibly select the specific size and style of the corrugated plate according to the gas flow rate, liquid content and separation efficiency requirements to be processed. This design not only improves the adaptability of the device, but also makes it easy to replace or adjust the structure of the corrugated plate 4 under different working conditions to achieve the best separation effect, thereby enhancing the flexibility and versatility of the device in industrial applications.
[0041] like Figure 5 As shown, the drain grooves 3 are placed below the corrugated plate 4, and the number thereof is consistent with the number of units of the corrugated plate 4. The structure and layout of the drain grooves 3 have been optimized, and the overall design is a long strip V-shaped design, which is conducive to guiding the liquid to gather to the center of the drain groove 3 and flow to the drain outlet 3-2 of the drain groove. At the same time, the interior thereof is divided into a plurality of independent unit separation grooves by arranging a plurality of partition plates 3-1, which blocks the airflow from directly acting on the droplets, and prevents the droplets from being rolled up or entrained by the airflow during the collection process, thereby ensuring that the liquid can be discharged stably and smoothly, and avoiding the accumulation of liquid in the drain groove 3, so as to improve the collection efficiency of the liquid and prevent the airflow from short-circuiting.
[0042] The length of the long side of the drain groove 3 is consistent with the straight-line distance from the entrance to the exit of the corrugated plate channel. The drain outlet 3-2 of the drain groove is connected to the drain pipe 2-6, which is used to collect small droplets separated by the corrugated plate 4 and drain them smoothly into the collecting tank 6-1. The height of the partition plate 3-1 is related to the depth of the drain groove 3, and its height range is 80% to 100% of the depth of the drain groove 3. At the same time, the spacing of the partition plates 3-1 is preferably 50% to 70% of the width of the drain groove 3. In order to further improve the discharge efficiency, the V-shaped structure at the bottom of the drain groove 3 guides the liquid to flow to the drain outlet 3-2 of the drain groove, and guides the liquid to the external drainage system through the drain pipe 2-6. The diameter D of the drain outlet o It is necessary to ensure that the liquid can be discharged quickly to avoid liquid retention. The design is based on the liquid discharge flow rate v l Calculation of the relationship between flow rate Q: This optimized design ensures that the liquid can be discharged stably and continuously, avoiding the problem of liquid backflow or retention caused by poor drainage. By optimizing the length of the drain groove 3, the size and spacing of the partition plate 3-1, and the design parameters of the drain groove outlet 3-2, the entire drain system shows higher efficiency and stability in liquid collection and discharge, providing reliable guarantee for the overall separation performance of the equipment.
[0043] The wire mesh 5 is a secondary separation component in the present invention, and its installation position is located in the M-shaped structural gap of the regular octagonal fixed frame, forming a uniformly distributed secondary separation area. The high specific surface area design of the wire mesh enables it to effectively capture fine droplets and tiny impurity particles remaining in the gas. The gas after preliminary separation by the corrugated plate 4 enters the secondary separation area where the wire mesh 5 is located to capture the fine droplets again, so that they gather and merge into larger droplets on the wire mesh, and further settle by gravity into the hydrophobic disk 6. The material of the wire mesh is generally high-strength corrosion-resistant metal wire, which is finely woven to form a multi-layer structure. This design not only ensures the smoothness of the airflow channel, but also fully improves the droplet capture efficiency. In order to enhance the versatility and adaptability of the equipment, the structural design of the wire mesh is highly flexible. Specifically, the shape, material and number of layers of the wire mesh can be customized according to user needs and specific application scenarios.
[0044] The drain pan 6 is connected to the external drainage system and consists of two parts: 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] like 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 the 8 groups of corrugated plates 4, and the gas enters the channels of the corrugated plates 4 for primary separation. The corrugated plates 4 use their corrugated structure to turn and collide the high-speed flowing gas, thereby capturing larger droplets, causing them to aggregate and flow downward along the surface of the corrugated plates, and finally converge to the hydrophobic groove 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 disc 6, and then turns back and flows upward into the wire mesh 5 for secondary separation, and the fine droplets are captured again, so that they gather and merge into larger droplets on the wire mesh, and further settle by gravity into the hydrophobic disc 6. The clean gas processed by the wire mesh 5 is finally discharged through the guide cover 1.
[0047] The present invention combines a corrugated plate and a wire mesh, and equips an optimized drainage structure under the wire mesh to achieve an efficient gas-liquid separation effect. The present invention aims to solve the common problems of droplet entrainment, unstable separation effect, gas-liquid secondary mixing, etc. in the existing gas-liquid separation device, and improve the separation efficiency and the stability of the device. The present invention captures large particles and fine droplets through the combination of corrugated plates and wire mesh to achieve comprehensive gas-liquid separation; adopts a V-shaped drainage structure to quickly discharge the separated liquid to prevent liquid retention and re-entrainment by high-speed airflow; and through the optimized structural layout and the use of corrosion-resistant materials, the stability and durability of the device under working conditions such as high humidity and high airflow speed are enhanced. 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, which allows the structural parameters and layout forms to be adjusted according to actual application requirements to adapt to different working conditions. In summary, the present invention provides an efficient, stable, and compact gas-liquid separation device, which is suitable for industrial fields such as petrochemicals, chemicals, and pharmaceuticals that require gas-liquid separation.
