Description

Technical Field

[0001] This utility model relates to the field of gas purification technology, and more specifically, to a device for reducing the water content in hydrogen gas used in the chlor-alkali industry. Background Technology

[0002] In the chlor-alkali industry, the presence of water in hydrogen can lead to equipment corrosion, reduced reaction efficiency, decreased hydrogen purity, increased separation and purification costs, and impaired catalyst performance, thereby affecting production efficiency, increasing operating costs, and potentially reducing product quality.

[0003] Gas purification equipment typically involves multiple electrical components. These components may generate static electricity during the regulation of pressure, flow rate, and the precipitation of water molecules. Once the accumulation of static electricity reaches a certain level, it can pose a safety hazard. Hydrogen, in particular, is a highly unstable gas with extremely high flammability and explosiveness. During normal operation, the release of static electricity or even a tiny spark can trigger a hydrogen explosion, causing a serious safety accident. Therefore, gas purification equipment must pay special attention to static electricity protection and explosion-proof design, adopting effective electrical isolation and grounding measures, and using explosion-proof electrical components.

[0004] In summary, how to provide a device for reducing the water content in hydrogen gas for the chlor-alkali industry is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a device for reducing the water content in hydrogen gas used in the chlor-alkali industry.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A device for reducing the water content in hydrogen gas used in the chlor-alkali industry includes a water-absorbing shell, a buffer shell fixedly connected to the outer surface of the water-absorbing shell, a guide plate fixedly connected to the inner surface of the buffer shell, a partition plate fixedly connected to the inner surface of the water-absorbing shell on the side away from the buffer shell, the partition plate being fixedly connected to the outer surface of the guide plate, a screening screen fixedly connected to the outer surface of the partition plate, the screening screen being staggered and fixedly connected to the outer surfaces of both sides of the partition plate, and an outlet shell fixedly connected to the upper surface of the water-absorbing shell.

[0007] On the other hand, a water guide plate is fixedly connected to the inner surface of the lower end of the water-absorbing shell away from the buffer shell, and a water storage tank is fixedly connected to the inner surface of the water-absorbing shell next to the water guide plate.

[0008] On the other hand, an adjusting plate is movably connected to the inner surface of the water-absorbing shell above the water storage tank. A threaded rod is welded to the outer surface of the adjusting plate on the side away from the partition plate. A nut is movably connected to the threaded rod through the outer surface of the water-absorbing shell.

[0009] On the other hand, a one-way air valve is provided on the outer surface of the buffer housing, and an air inlet pipe is fixedly connected to the outer surface of the one-way air valve.

[0010] On the other hand, a heat exchange shell is fixedly connected to the outer surface of the air inlet pipe, and a water pump is fixedly connected to the outer surface of the heat exchange shell.

[0011] On the other hand, a bidirectional water pipe is fixedly connected to the outer surface of the water pump, and a connecting collar is provided through the water suction shell on the outer surface of the water storage tank. The bidirectional water pipe is detachably connected at the connecting collar end.

[0012] On the other hand, an outlet air pipe is fixedly connected to the outer surface of the outlet shell, and the outer surface of the outlet air pipe penetrates the heat exchange shell for a fixed connection.

[0013] On the other hand, the partition plate is made of PTFE (polytetrafluoroethylene), and foamed sponge is filled between the partition plate and the screening mesh in a second layer.

[0014] This utility model provides a device for reducing the water content in hydrogen gas used in the chlor-alkali industry. The device employs a conical design for the buffer shell. After the airflow enters through a one-way valve, the surface area suddenly increases, and the airflow velocity decreases. Guided downwards by the guide plate, the cooled airflow separates, causing water to liquefy into a mist, while the hydrogen remains unchanged. The mist merges upon contact, forming larger, heavier particles that continuously permeate through the sieve between the separator plates. The lighter hydrogen gradually rises, while the water adheres to the separator plates and sieve, condensing and flowing downwards. The foamed sponge filling the space between the separator plates and sieve provides good airtightness and flame retardancy, facilitating the release of hydrogen and water. Hydrogen is discharged from the top through the outlet shell. The overall layered design and multiple separations ensure the quality of water absorption. Water flows through the slope created by the guide plate and is guided by gravity to a storage tank. During prolonged use, the separator plates and sieve are frequently immersed in water and subjected to temperature changes, causing damage to the separator plates and sieve. The permeability of the screening screen and foamed sponge changes. By rotating the nut, the space on the corresponding side of the adjustment plate is adjusted, thereby adjusting the buffer pressure of the precipitation space. The gas to be purified enters through the inlet pipe. The one-way valve ensures that the gas can only enter and not exit through the buffer shell. The water inside the heat exchange shell absorbs the heat of the gas at the inlet pipe, which heats up the purified and cooled gas. The water pump facilitates the replacement of the hotter water at the water storage tank with the cold water at the heat exchange shell. The water pump, through the bidirectional water pipe, facilitates the replacement of the hot water at the water storage tank with the heat exchange shell. The water can be easily discharged through the bidirectional water pipe and the detachable connecting collar. The whole device uses the original resources for heat exchange, avoiding excessive waste. The exhaust pipe discharges the purified gas. After being discharged, the gas passes through the heat exchange shell, and the cooled gas is steadily heated again. PTFE (polytetrafluoroethylene) material is known for its chemical stability and high temperature resistance, and is widely used in chemical, pharmaceutical and food processing fields. It has extremely strong acid and alkali resistance, and can maintain stable physical properties under harsh conditions such as strong acids, alkalis, and salt spray, thus extending its service life. The foamed sponge has good airtightness, flame retardancy, and facilitates the release of hydrogen and water.

[0015] Compared with the prior art, this utility model has a simple and detachable structure, high water separation efficiency in the gas and convenient water removal device, and makes full use of existing resources for heat exchange, avoiding excessive waste. Attached Figure Description

[0020] The core of this invention is to provide a device for reducing the water content in hydrogen gas used in the chlor-alkali industry.

[0021] Please refer to Figures 1-4A device for reducing the water content in hydrogen gas used in the chlor-alkali industry includes a water-absorbing shell 1, a buffer shell 2 fixedly connected to the outer surface of the water-absorbing shell 1, a guide plate 3 fixedly connected to the inner surface of the buffer shell 2, a partition plate 4 fixedly connected to the inner surface of the water-absorbing shell 1 on the side away from the buffer shell 2, the partition plate 4 being fixedly connected to the outer surface of the guide plate 3, a screening screen 5 fixedly connected to the outer surface of the partition plate 4, the screening screen 5 being staggered and fixedly connected to the outer surfaces of the two sides of the partition plate 4, and an outlet shell 6 fixedly connected to the upper surface of the water-absorbing shell 1. Specifically, the buffer shell 2 adopts a conical design, and the surface area suddenly increases after the airflow enters through the one-way valve 12. As the airflow velocity decreases, it is guided downwards by the guide plate 3, causing the cooled airflow to separate. Water liquefies into a liquid state, becoming mist, while hydrogen remains unchanged. The mist merges upon contact, forming larger particles that become heavier. These particles continuously permeate through the sieve 5 between the partition plate 4. The lighter hydrogen gradually rises, while the water adheres to the partition plate 4 and sieve 5, condensing to a certain extent before flowing down. The foamed sponge filling the space between the partition plate 4 and sieve 5 provides good airtightness and flame retardancy, facilitating the release of hydrogen and water. The hydrogen is discharged from above through the outlet shell 6. The overall layered design and multiple separations ensure the quality of water absorption.

[0022] A water guide plate 7 is fixedly connected to the inner surface of the lower end of the water-absorbing shell 1 away from the buffer shell 2, and a water storage tank 8 is fixedly connected to the inner surface of the water-absorbing shell 1 next to the water guide plate 7; specifically, water flows through the slope generated by the water guide plate 7 and is guided to the water storage tank 8 for storage under the action of gravity.

[0023] An adjusting plate 9 is movably connected to the inner surface of the water-absorbing shell 1 above the water storage tank 8. A threaded rod 10 is welded to the outer surface of the adjusting plate 9 away from the partition plate 4. The threaded rod 10 passes through the outer surface of the water-absorbing shell 1 and is movably connected to a nut 11. Specifically, during long-term use, the partition plate 4 and the screening screen 5 are often soaked in water and subjected to temperature changes, which causes changes in the air permeability of the partition plate 4, the screening screen 5 and the foamed sponge. By rotating the nut 11, the space on the corresponding side of the adjusting plate 9 is adjusted, thereby adjusting the buffer pressure of the precipitation space.

[0024] A one-way air valve 12 is provided on the outer surface of the buffer housing 2, and an air inlet pipe 13 is fixedly connected to the outer surface of the one-way air valve 12; specifically, the gas to be purified enters through the air inlet pipe 13, and the one-way air valve 12 ensures that the gas can only enter through the buffer housing 2 and not exit.

[0025] A heat exchange shell 14 is fixedly connected to the outer surface of the air inlet pipe 13, and a water pump 15 is fixedly connected to the outer surface of the heat exchange shell 14. Specifically, the water inside the heat exchange shell 14 absorbs the heat of the gas at the air inlet pipe 13 to raise the temperature of the purified and cooled gas. The water pump 15 facilitates the replacement of the water at the higher temperature in the water storage tank 8 with the cold water at the heat exchange shell 14.

[0026] A bidirectional water pipe 16 is fixedly connected to the outer surface of the water pump 15. A connecting collar 17 is provided through the water suction shell 1 on the outer surface of the water storage tank 8. The bidirectional water pipe 16 is detachably connected at the end of the connecting collar 17. Specifically, the water pump 15 facilitates the replacement of hot water in the water storage tank 8 with the heat exchange shell 14 through the bidirectional water pipe 16. The water can be easily discharged through the detachable bidirectional water pipe 16 and connecting collar 17. The whole device utilizes the original resources for heat exchange and avoids excessive waste.

[0027] An outlet gas pipe 18 is fixedly connected to the outer surface of the outlet shell 6. The outer surface of the outlet gas pipe 18 penetrates the heat exchange shell 14 and is fixedly connected. The outlet gas pipe 18 exports the purified gas. After the outlet gas pipe 18 is exported, it passes through the heat exchange shell 14, and the cooled gas is steadily heated again.

[0028] The separator 4 is made of PTFE (polytetrafluoroethylene), and a second layer of foamed sponge fills the space between the separator 4 and the screening mesh 5. Specifically, PTFE (polytetrafluoroethylene) is known for its chemical stability and high-temperature resistance, and is widely used in chemical, pharmaceutical, and food processing industries. It has extremely strong acid and alkali resistance, maintaining stable physical properties under harsh conditions such as strong acids, alkalis, and salt spray, thus extending its service life. The foamed sponge has good airtightness, flame retardancy, and facilitates the release of hydrogen and water.

[0029] In summary: The gas enters through the inlet pipe 13 and is enclosed by the heat exchange shell 14. The water inside the heat exchange shell 14 absorbs heat. The one-way valve 12 ensures that the gas enters through the buffer shell 2 but does not exit. The buffer shell 2 has a conical design. After the airflow enters through the one-way valve 12, the surface area suddenly increases, and the airflow velocity decreases. At the same time, the temperature decreases under the influence of heat absorption by the external heat exchange shell 14. Through the downward guidance of the guide plate 3, the cooled airflow separates. The water liquefies into a liquid state, becoming mist, while the hydrogen remains unchanged. After the mist comes into contact with each other, it merges to form larger particles, which become heavier. In the middle of the separator plate 4, it continuously permeates the sieve 5. The lighter hydrogen gradually rises, while the water adheres to the separator plate 4 and the sieve 5, condensing to a certain extent and flowing down. The foamed sponge filling between the separator plate 4 and the sieve 5 has good airtightness and flame retardancy, facilitating the precipitation of hydrogen and water. The water passes through the water guide plate 7. The water is directed to the water storage tank 8. During long-term use, the partition plate 4 and the sieve screen 5 are frequently soaked in water and subject to temperature changes, causing changes in the air permeability of the partition plate 4, the sieve screen 5, and the foam sponge. By rotating the nut 11, the space on the corresponding side of the adjusting plate 9 is adjusted to regulate the buffer pressure of the precipitation space, further adjusting the air permeability of the partition plate 4, the sieve screen 5, and the foam sponge to ensure the water absorption effect. Hydrogen is discharged from the top through the outlet shell 6. The overall layered design and multiple separations ensure the quality of water absorption. After being discharged through the outlet gas pipe 18, the gas passes through the heat exchange shell 14, and the cooled gas is steadily reheated. The water pump 15 facilitates the replacement of hot water in the water storage tank 8 with water in the heat exchange shell 14 through the bidirectional water pipe 16. The water is easily discharged through the detachable bidirectional water pipe 16 and the connecting collar 17. The entire device utilizes existing resources for heat exchange, avoiding excessive waste.
