Description

Technical Field

[0001] This utility model relates to the field of gas-liquid separation technology, and in particular to a novel gas-liquid separation device. Background Technology

[0002] Hydrogen (H2) is a clean and efficient secondary energy carrier that has played an increasingly important role in promoting energy transition and achieving the "dual carbon" goal in recent years. Hydrogen has a wide range of applications, mainly concentrated in transportation, industry, energy and construction.

[0003] Existing hydrogen production plants use purification equipment to analyze the purity of crude hydrogen. During purification, the crude hydrogen is transported to a water washing tank. The crude hydrogen gas stream is brought into countercurrent contact with water (circulating water or demineralized water) in the tank. Through physical actions such as dissolution, wetting and entrainment, some impurities are removed, including ammonia, chloride, dust and some soluble gases. The process also involves cooling and humidifying the crude hydrogen to facilitate subsequent processing.

[0004] However, after the pure water in the washing tank is used, it will enter the pure water drainage pipe and be discharged into the factory. The water will be filtered and cleaned for reuse. During the drainage process, some crude hydrogen will be discharged into the factory along with the pure water in the washing tank. Since hydrogen has a low density, the diffused hydrogen will accumulate on the top of the factory and cannot be discharged in time. Furthermore, the residual hydrogen flow rate cannot be observed, thus creating a potential safety hazard. Therefore, a new gas-liquid separation device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel gas-liquid separation device, which aims to improve the safety hazard caused by residual crude hydrogen being discharged into the factory through the pure water drainage pipe in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A novel gas-liquid separation device includes a separation tank, an inlet pipe fixedly connected to the bottom of the separation tank, an exhaust pipe fixedly connected to the top of the separation tank, a drain pipe fixedly connected to the bottom of the separation tank, an installation assembly provided on the outside of the separation tank, and an adjustment assembly provided at the bottom of the separation tank. The regulating component includes a connecting pipe, which is fixedly connected to the outlet end of the first drain pipe. The end of the connecting pipe away from the first drain pipe is fixedly connected to the second drain pipe. A U-shaped pipe is fixedly connected to the top of the connecting pipe. The other end of the U-shaped pipe is fixedly connected to the middle of the second drain pipe. A ball valve is rotatably connected inside the connecting pipe. An adjusting knob is fixedly connected to the outside of the ball valve. As a further description of the above technical solution: The installation assembly includes a fixing ring, which is fixedly connected to the outside of the separation tank. An L-shaped block is fixedly connected to the outside of the fixing ring, and the L-shaped block has multiple fixing holes in the middle. As a further description of the above technical solution: The top of the separation tank is fixedly connected to a top cover, and the exhaust pipe is fixedly connected inside the top cover; As a further description of the above technical solution: The bottom of the separator is fixedly connected to a bottom cover, and the water inlet pipe and the water outlet pipe are both fixedly connected inside the bottom cover; As a further description of the above technical solution: The separation tank is made of transparent acrylic material; As a further description of the above technical solution: One end of the exhaust pipe is fixedly connected to flange one, and one end of the water inlet pipe is fixedly connected to flange two. Both flange one and flange two have multiple mounting holes in the middle. As a further description of the above technical solution: The ball valve has three interconnecting holes inside, and the three interconnecting holes are connected to each other. As a further description of the above technical solution: The ball valve is located between the second drain pipe and the first drain pipe, and the adjusting knob is rotatably connected to the outside of the connecting pipe.

[0007] This utility model has the following beneficial effects: 1. In this utility model, by setting up a separation tank, a water inlet pipe, a drain pipe and an exhaust pipe, the water in the pure water drain pipe of the crude hydrogen washing tank is discharged into the separation tank, and the hydrogen is discharged from the exhaust pipe through the separation tank. This prevents the crude hydrogen from entering the pure water drain pipe and being discharged into the factory building along with the pure water in the washing tank after passing through the washing tank, thus ensuring the safety of the factory building and workers.

[0008] 2. In this utility model, the water inlet pipe is connected to the inside of the separator tank and is 30mm higher than the bottom of the separator tank so that the hydrogen in the pure water can be discharged. At the same time, a U-shaped pipe is installed on the drain pipe so that the water in the separator tank can stay for a period of time to allow the hydrogen to be fully discharged. The discharge and cleaning of the separator tank are then controlled by a ball valve. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a novel gas-liquid separation device, comprising a separation tank 1, which is the main body of the gas-liquid separation device. The liquid to be separated is discharged into the separation tank 1 for gas-liquid separation. A water inlet pipe 2 is fixedly connected to the bottom of the separation tank 1. The height of the water inlet pipe 2 is 30mm higher than the bottom of the separation tank 1. The water inlet pipe 2 is connected to a pure water venting pipe to transport the liquid to be separated into the separation tank 1 for gas-liquid separation. An exhaust pipe 7 is fixedly connected to the top of the separation tank 1. The separated gas will exist inside the separation tank 1. The separated hydrogen is discharged through the exhaust pipe 7. The exhaust pipe 7 is connected to an external hydrogen venting pipe to transport the hydrogen in the separation tank 1 to the hydrogen venting pipe. A drain pipe 3 is fixedly connected to the bottom of the separation tank 1. The water after gas-liquid separation is discharged from the drain pipe 3. An installation component is provided on the outside of the separation tank 1, and an adjustment component is provided at the bottom of the separation tank 1. The regulating assembly includes a connecting pipe 4, which is fixedly connected to the outlet end of drain pipe 3. A second drain pipe 6 is fixedly connected to the end of the connecting pipe 4 furthest from drain pipe 3, connecting drain pipe 3 and drain pipe 6. A U-shaped pipe 5 is fixedly connected to the top of the connecting pipe 4, and the other end of the U-shaped pipe 5 is fixedly connected to the middle of drain pipe 6, also connecting drain pipe 3 and drain pipe 6. A ball valve 15 is rotatably connected inside the connecting pipe 4, controlling the drainage direction of drain pipe 3. An adjusting knob 17 is fixedly connected to the outside of the ball valve 15, controlling the ball valve 15 to change the drainage path. The separating tank 1 is made of transparent acrylic material, allowing a clear view of the interior from the outside. To facilitate observation of the water-vapor separation effect, the ball valve 15 has three interconnected holes 16. These three interconnected holes 16 control the water flow from the connecting pipe 4 directly to the drain pipe 6, or through the U-shaped pipe 5 to the drain pipe 6. The ball valve 15 is located between the drain pipe 6 and the drain pipe 3. The adjusting knob 17 is connected to the outside of the connecting pipe 4. Rotating the adjusting knob 17 from the outside changes the position of the internal connecting holes 16 of the ball valve 15, thus changing the drainage route and achieving different functions. During gas-liquid separation, water flows out from the U-shaped pipe 5, keeping sufficient water inside the separation tank 1. When cleaning the separation tank 1, water flows directly from the connecting pipe 4 to the drain pipe 6 to drain all the water inside the separation tank 1 for cleaning.

[0013] Reference Figures 1-3 The installation components include a fixing ring 10, which is fixedly connected to the outside of the separator tank 1. The fixing ring 10 is fixed to the outside of the separator tank 1 with screws. The fixing ring 10 can be removed for maintenance and replacement using screws. An L-shaped block 11 is fixedly connected to the outside of the fixing ring 10. The L-shaped block 11 is integrally connected to the fixing ring 10 during production, providing support for the fixing ring 10. The L-shaped block 11 has multiple fixing holes 13 in the middle. The fixing holes 13 are all circular. The separator tank 1 can be fixed in the required position by passing bolts through the fixing holes 13. The position can also be changed using screws. It is very convenient to use and allows the position of the separator tank 1 to be adjusted at will. However, the height of the separator tank 1 during installation cannot exceed the height of the original pure water drain pipe.

[0014] Reference Figure 2 , Figure 3 and Figure 5The top of the separator 1 is fixedly connected to a top cover 8, and the exhaust pipe 7 is fixedly connected inside the top cover 8. The top cover 8 improves the sealing performance of the top of the separator 1, preventing gas leakage at the connection point when the exhaust pipe 7 is connected to the separator 1, thus avoiding the safety hazard caused by hydrogen leakage. The bottom of the separator 1 is fixedly connected to a bottom cover 9, and the water inlet pipe 2 and the drain pipe 3 are both fixedly connected inside the bottom cover 9. The bottom cover 9 has the same function as the top cover 8, which is to maintain the sealing performance of the water inlet pipe 2 and the drain pipe 3 when connected to the separator 1. One end of the exhaust pipe 7 is fixedly connected to a flange 12, and one end of the water inlet pipe 2 is fixedly connected to a flange 14. Both the ends of the water inlet pipe 2 and the exhaust pipe 7 are provided with connecting flanges, which makes it easier to connect to the pure water venting pipe and the hydrogen venting pipe and prevents leakage. Both flange 12 and flange 14 have multiple mounting holes 18 in the middle, which facilitate the passage of bolts and strengthen the sealing performance.

[0015] Working principle: First, the separator 1 is fixed in the installation position with screws by the fixing ring 10 and L-shaped block 11 on the outside of the separator 1. During installation, the overall height of the separator 1 shall not be higher than the horizontal height of the pure water drain pipe of the crude hydrogen water washing tank. Then, the pure water drain pipe of the crude hydrogen water washing tank is connected to the water inlet pipe 2 at the bottom of the separator 1 and fixed with flange 14 and mounting hole 18. Then, the exhaust pipe 7 at the top of the separator 1 is connected to the hydrogen vent pipe and fixed with flange 12 and mounting hole 18. Water from the pure water drain pipe of the crude hydrogen water washing tank can be discharged into the separator 1, and hydrogen in the water is discharged from the exhaust pipe 7. The water inside is discharged from the drain pipe 3 at the bottom.

[0016] Next, rotate the adjusting knob 17 to rotate the ball valve 15 inside the connecting pipe 4. When the adjusting knob 17 is pointed towards the drain pipe 2 6, the connecting hole 16 inside the ball valve 15 will connect the drain pipe 1 3 to the U-shaped pipe 5. When the water inside the separator tank 1 is higher than the height of the U-shaped pipe 5, the water inside the separator tank 1 will be drained. The water is transported from the U-shaped pipe 5 to the drain pipe 2 6 and drained out through the drain pipe 2 6. When it is necessary to clean the water inside the separator tank 1, turn the adjusting knob 17 downward so that the ball valve 15 connects the drain pipe 1 3 to the drain pipe 2 6, so that all the water inside the separator tank 1 can be drained out for cleaning. When it is necessary to close the separator tank 1, turn the adjusting knob 17 towards the drain pipe 1 3 so that the ball valve 15 can close the drain pipe 1 3.

[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
