[0002] Most existing gas-liquid separation devices rely on gravity separation or simple mechanical separation methods. These traditional methods have obvious limitations when dealing with large amounts of gas-liquid mixtures, such as low separation efficiency, limited gas discharge, gas carrying a lot of liquid, affecting the use of subsequent gas and making it inconvenient to clean the container. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-stage gas-liquid separation and diversion device for an electrolytic cell used with PPS fiber membranes.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] This application provides a multi-stage gas-liquid separation and diversion device for an electrolytic cell used with PPS fiber membranes, including a tank, a first support plate, an exhaust fan, a first umbrella plate, an inlet pipe, a water inlet pipe, sprayers, an outlet, an exhaust port, and a diversion assembly. The inner wall of the tank is provided with a first support plate, and the exhaust fan is fixedly connected to the first support plate. The lower end of the first support plate is provided with a first umbrella plate. The upper side of the tank is seamlessly connected to the inlet pipe, which is seamlessly connected to the diversion assembly. The lower side of the tank is seamlessly connected to the water inlet pipe, which is provided with multiple sprayers. The water inlet pipe is fixedly connected to the lower end of the diversion assembly. The bottom of the tank is provided with an outlet, and the top of the tank is provided with an exhaust port.
[0006] Furthermore, the first umbrella plate has multiple holes.
[0007] Furthermore, a water level gauge is provided on the outside of the tank.
[0008] Furthermore, the diversion assembly includes a diversion pipe, a spiral slide, a second support plate, a second umbrella plate, a baffle, and a third support plate. The inlet pipe is seamlessly connected to the top of the diversion pipe, and the bottom of the diversion pipe is seamlessly connected to the top of the spiral slide. The connection between the spiral slide and the inlet pipe is provided with the second support plate. The second support plate is fixedly connected to the inner wall of the tank. Multiple second umbrella plates are fixedly provided at the bottom of the second support plate. The baffle is provided on the outer ring of the spiral slide, and the bottom of the spiral slide is provided on the third support plate.
[0009] Furthermore, the water inlet pipe is fixedly connected to the bottom of the third support plate.
[0010] Furthermore, the spiral slide is provided with micropores.
[0011] Furthermore, the diameter of the second umbrella plate is larger than the diameter of the spiral slide.
[0012] Furthermore, the spiral slide is arranged vertically.
[0013] Furthermore, the number of the diversion pipes is equal to the number of the spiral slides.
[0014] Furthermore, the inlet pipe, the diversion pipe, and the spiral slide are internally connected.
[0015] The beneficial effects of this utility model are:
[0016] 1) The main function of the exhaust fan is to accelerate the flow and discharge of gas inside the tank. During the gas-liquid separation process, it generates negative pressure, causing the gas inside the tank to flow rapidly towards the exhaust port, thus accelerating the gas-liquid separation speed and improving separation efficiency. By timely discharging the gas, it prevents gas accumulation inside the tank from affecting further liquid separation and flow, maintaining a good gas-liquid balance within the device.
[0017] 2) During the gas-liquid separation process, it generates negative pressure, causing the gas inside the tank to flow rapidly towards the exhaust port, accelerating the gas-liquid separation speed and improving separation efficiency. By timely venting the gas, it prevents gas accumulation inside the tank from affecting further liquid separation and flow, maintaining a good gas-liquid balance within the device. Because water droplets are heavier, they settle downwards, while the gas moves upwards. Upon passing through the first umbrella plate, the gas separates larger water droplets carried by the gas, causing the water droplets to condense on the first umbrella plate and flow downwards. The gas, being lighter, continues to move upwards, thus achieving the third gas-liquid separation.
[0018] 3) By installing multiple sprayers on the water inlet pipe, water is evenly distributed in the tank in the form of sprays. These spray waters can provide high-pressure rinsing for the storage containers containing the separated solution. Attached Figure Description

Detailed Implementation
[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] See Figures 1-4 This utility model provides a technical solution:
[0026] A multi-stage gas-liquid separation and diversion device for an electrolytic cell used with PPS fiber membranes includes a tank 1, a first support plate 2, an exhaust fan 3, a first umbrella plate 4, an inlet pipe 5, a water inlet pipe 6, sprayers 7, an outlet 8, an exhaust port 9, and a diversion assembly. The inner wall of the tank 1 is provided with the first support plate 2, and the exhaust fan 3 is fixedly connected to the first support plate 2. The lower end of the first support plate 2 is provided with the first umbrella plate 4. The upper side of the tank 1 is seamlessly connected to the inlet pipe 5, which is seamlessly connected to the diversion assembly. The lower side of the tank 1 is seamlessly connected to the water inlet pipe 6, which is provided with multiple sprayers 7 and is fixedly connected to the lower end of the diversion assembly. The bottom of the tank 1 is provided with the outlet 8, and the top of the tank 1 is provided with the exhaust port 9. The tank 1 serves as the main structure of the entire device, providing installation space and a suitable environment for other components. The first support plate 2 plays a crucial role in supporting and fixing the exhaust fan 3, providing a stable installation platform for it and ensuring that the exhaust fan 3 can perform its functions such as air extraction normally and efficiently. Simultaneously, it divides the interior of the device into upper and lower functional areas, facilitating the orderly execution of the gas-liquid separation process. The main function of the exhaust fan 3 is to accelerate the flow and discharge of gas within the tank 1. During the gas-liquid separation process, it generates negative pressure, causing the gas within the tank 1 to flow rapidly towards the exhaust port 9, accelerating the gas-liquid separation speed and improving separation efficiency. By timely discharging the gas, it prevents gas accumulation within the tank 1 from affecting further liquid separation and flow, maintaining a good gas-liquid balance within the device. Because water droplets have weight, they settle downwards, while gas moves upwards. Upon passing the first umbrella plate 4, the larger water droplets carried by the gas are separated, causing the water droplets to condense on the first umbrella plate 4, thus accumulating and flowing downwards. The gas, being lighter, continues to move upwards, achieving a third gas-liquid separation. The liquid inlet pipe 5 is the channel through which raw materials containing the gas-liquid mixture enter the device. It introduces the gas-liquid mixture from upstream equipment such as the diaphragm electrolyzer into tank 1, which is seamlessly connected to the distribution component. This ensures the smooth and stable entry of the material into the distribution component, laying the foundation for subsequent rational material allocation and gas-liquid separation. The water inlet pipe 6 introduces clean water into the device. Multiple sprayers 7 are installed on the water inlet pipe 6 to evenly distribute water within tank 1 in a spraying manner. This spray water can provide high-pressure rinsing for the storage tank containing the separated solution. The liquid outlet 8 is the discharge channel for the separated or cleaned liquid. After multi-stage gas-liquid separation, the relatively pure liquid flows out from the liquid outlet 8, facilitating its transport to subsequent process stages for further processing or use, thus realizing the device's function of collecting and guiding liquid. The exhaust port 9, located at the top of tank 1, is the discharge channel for the separated gas. The gas flowing through tank 1, accelerated by components such as the exhaust fan 3, is finally discharged from the device through the exhaust port 9, ensuring smooth gas discharge, maintaining pressure balance within the device, and ensuring the continuous and stable operation of the gas-liquid separation process.
[0027] In some embodiments, the first umbrella plate 4 has a plurality of holes 10. The holes 10 provide exhaust channels for the third gas-liquid separation, allowing the gas to continue to move upward.
[0028] In some embodiments, a water level gauge 11 is provided on the outside of the tank 1. The water level gauge 11 allows operators to intuitively and in real time understand the water level inside the tank 1, thereby adjusting the water level according to different production needs. The water level gauge 11 provides operators with a clear reference.
[0029] In some embodiments, the diversion assembly includes a diversion pipe 12, a spiral slide 13, a second support plate 14, a second umbrella plate 15, a baffle 16, and a third support plate 17. The liquid inlet pipe 5 is seamlessly connected to the top of the diversion pipe 12, and the bottom of the diversion pipe 12 is seamlessly connected to the top of the spiral slide 13. The connection between the spiral slide 13 and the diversion pipe 12 is provided with the second support plate 14, which is fixedly connected to the inner wall of the tank 1. A plurality of second umbrella plates 15 are fixedly provided at the bottom of the second support plate 14. A baffle 16 is provided on the outer ring of the spiral slide 13, and the bottom of the spiral slide 13 is provided on the third support plate 17. The diversion pipe 12 is connected to the liquid inlet pipe 5, which can evenly distribute the gas-liquid mixture entering the device into the spiral slide 13. Through reasonable pipe diameter design and internal structure, the material is ensured to be evenly distributed in the circumferential direction, creating favorable conditions for subsequent gas-liquid separation on the spiral slide 13. The gas-liquid mixture flows along a spiral trajectory on the spiral slide 13, allowing the gas to separate from the liquid more frequently, thus improving separation efficiency. The second support plate 14 is fixedly connected to the inner wall of the tank 1, providing stable support for the connection between the diversion pipe 12 and the spiral slide 13. It ensures the relative position stability of the diversion pipe 12 and the spiral slide 13 during device operation, preventing loosening or displacement of the connection due to vibration, material impact, or other factors. This ensures the gas-liquid mixture can smoothly transition from the diversion pipe 12 to the spiral slide 13, maintaining the normal operation of the device. Multiple second umbrella plates 15 are provided at the bottom of the second support plate 14 to perform a second gas-liquid separation on the gas separated on the spiral slide 13. A baffle 16 is located on the outer ring of the spiral slide 13, restricting the gas-liquid mixture from flowing along a predetermined spiral trajectory within the spiral slide 13, preventing material overflow. It guides the gas and liquid to slide steadily down the spiral path, ensuring sufficient contact and separation within the slide, and preventing reduced separation efficiency due to disordered material flow. By constraining the gas-liquid flow path, the baffle 16 makes the residence time of gas and liquid within the spiral slide 13 more controllable, increasing the opportunity for gas-liquid interaction and further improving the degree of gas-liquid separation. Simultaneously, it also helps maintain the stability of the gas-liquid flow within the spiral slide 13, reducing the problem of decreased separation efficiency caused by flow turbulence. The third support plate 17 is located at the bottom of the spiral slide 13, providing reliable support for the spiral slide 13 and bearing the weight of the spiral slide 13 and the gas-liquid mixture flowing inside it. Furthermore, the diameter of the third support plate 17 is smaller than that of the spiral slide 13, and the bottom extension of the spiral slide 13 extends outside the third support plate 17. This allows it to guide the separated liquid smoothly to the outlet 8 at the bottom of the tank 1, while providing a reasonable spatial layout for the upward discharge of gas, ensuring smooth gas-liquid flow within the device and improving the overall operating efficiency of the device.
[0030] In some embodiments, the water inlet pipe 6 is fixedly connected to the bottom of the third support plate 17. Fixing the water inlet pipe 6 to the bottom of the third support plate 17 makes the internal space layout of the device more compact and provides reliable support. This layout avoids the water inlet pipe 6 occupying too much independent space within the tank 1, enhancing the stability of the water inlet pipe 6 during device operation.
[0031] In some embodiments, the spiral slide 13 is provided with micropores 18. The unseparated liquid in the diversion pipe 12 flows into the spiral slide 13 through the micropores 18 for preliminary separation.
[0032] In some embodiments, the diameter of the second umbrella plate 15 is larger than the diameter of the spiral slide 13. The second umbrella plate 15 performs a second gas-liquid separation on the gas separated from the spiral slide 13, causing larger water droplets to condense on the second umbrella plate 15. The condensed water droplets then accumulate and flow downwards along the outer circumference of the second umbrella plate 15 to the liquid outlet 8.
[0033] In some embodiments, the spiral chute 13 is arranged vertically. This vertical arrangement allows gravity and centrifugal force to work together as the gas and liquid flow within the spiral chute 13. The liquid tends to flow downwards under gravity, which, combined with the centrifugal force causing the liquid to adhere to the inner wall, enhances the separation of the liquid and gas. The vertical arrangement allows for more efficient use of vertical space within a limited area, enabling the device to extend the gas-liquid separation path and improve separation efficiency even with a smaller footprint by increasing the height of the spiral chute 13. This arrangement is particularly suitable for space-constrained industrial environments.
[0034] In some embodiments, the number of diversion pipes 12 and spiral slides 13 is equal. This equal number ensures a one-to-one correspondence between the diversion pipes 12 and spiral slides 13, achieving precise material diversion. Each diversion pipe 12 accurately distributes the gas-liquid mixture to its corresponding spiral slide 13, avoiding uneven diversion that could lead to some spiral slides 13 being overloaded while others are underloaded. This allows each spiral slide 13 to fully perform its gas-liquid separation function, improving the overall separation efficiency and stability of the device. The equal number of pipes also facilitates operator control and management of the device.
[0035] In some embodiments, the inlet pipe 5, the diversion pipe 12, and the spiral slide 13 are internally connected. This internally connected structure ensures that the gas-liquid mixture can smoothly flow from the inlet pipe 5 through the diversion pipe 12 into the spiral slide 13 without obstruction.
