Description

Technical Field

[0001] This utility model relates to the field of hydrogen purification technology, specifically a hydrogen desulfurization and purification device. Background Technology

[0002] Hydrogen is widely used in many fields as a clean energy source and an important industrial raw material. However, hydrogen produced in industrial production usually contains impurities such as sulfides. These sulfides not only reduce the quality of hydrogen, but also corrode the equipment used in subsequent applications, affecting the service life of the equipment and production safety. For example, in the field of fuel cells, sulfides can poison the catalyst, leading to a decrease in battery performance and a reduction in power generation efficiency of up to 30% to 50%.

[0003] Currently, commonly used hydrogen desulfurization and purification methods include dry desulfurization and wet desulfurization. While dry desulfurization offers advantages such as simple equipment and convenient operation, it suffers from difficulties in desulfurizing the desulfurizing agent, high operating costs, and limited desulfurization precision, making it difficult to reduce the sulfide content in hydrogen to a low level. Wet desulfurization, although relatively efficient, suffers from complex processes, high equipment investment, and the generation of large amounts of wastewater, resulting in high wastewater treatment costs and potential secondary pollution. Furthermore, existing hydrogen purification devices often suffer from insufficient contact between the gas and the desulfurizing agent during the desulfurization process, leading to unsatisfactory desulfurization results and failing to meet the ever-increasing demand for high-purity hydrogen. Therefore, a hydrogen fine desulfurization and purification device is proposed. Utility Model Content

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.

[0022] Please see Figures 1-4 This utility model discloses a hydrogen desulfurization and purification device, including a purification box 1. A support frame 2 is fixedly connected to one side of the outer wall of the purification box 1. A top air inlet tank 3 is fixedly connected to the top of the support frame 2 through a connecting top seat 8. An air inlet pipe 4 is fixedly connected to one end of the top air inlet tank 3 through a tank opening 5.

[0023] Multiple mounting brackets 6 are fixedly connected to the inner wall of the top air inlet tank 3. Filter plates 7 are fixedly connected to the inner wall of the multiple mounting brackets 6. Multiple bases 10 are fixedly connected to the bottom of the support frame 2. A rinsing and dust removal tank 9 is fixedly connected to the top of the multiple bases 10. Multiple fixing rings 11 are fixedly connected to the outer wall of the rinsing and dust removal tank 9. A water inlet pipe 13 is fixedly connected to one end of the rinsing and dust removal tank 9 through a tank opening 14. A conduction pipe 12 is fixedly connected to the other end of the rinsing and dust removal tank 9. The end of the conduction pipe 12 away from the rinsing and dust removal tank 9 is fixedly connected to one side of the purification box 1.

[0024] Specifically, this hydrogen desulfurization and purification device uses the purification chamber 1 as the core processing unit. The top inlet tank 3 is fixed above the purification chamber 1 via a support frame 2, forming a gas pretreatment and introduction structure. The filter plate 7 inside the top inlet tank 3 performs preliminary filtration of the incoming hydrogen. The rinsing and dust removal tank 9 is connected to the water inlet pipe 13, which can wash and remove dust from the hydrogen, removing some impurities and dust. The transmission pipe 12, transmission water pipe 15, water source conduit 17, diversion pipe 18, and nozzle 19 form a water washing system to ensure the rinsing effect. The drive motor 21, transmission gear set 22, and stirring rod 23 constitute a stirring system to promote the full mixing and reaction of hydrogen and desulfurizing agent. Filter plate 2... Unit 24 is used to filter and separate purified hydrogen to ensure the purity of the output hydrogen. The various structural parts work together to realize the whole process of hydrogen treatment from preliminary filtration, water washing and dust removal to deep desulfurization and purification. The support frame 2 is welded from high-strength steel, which has good stability and load-bearing capacity and can stably support the top air inlet tank 3. The top air inlet tank 3 is fixed to the top of the support frame 2 through the connecting top seat 8. The air inlet pipe 4 is connected to the top air inlet tank 3 through the tank opening 5 to ensure that the hydrogen can smoothly enter the top air inlet tank 3. Multiple fixing frames 6 on the inner wall of the top air inlet tank 3 are arranged in a ring array to provide stable support for the filter plate 7. The filter plate 7 is made of stainless steel wire mesh with a pore size of 5-10μm, which can effectively intercept larger particles of impurities in hydrogen, such as rust and dust, to perform preliminary filtration of hydrogen and reduce the load of subsequent processing.

[0025] In this embodiment, one end of the transmission pipe 12 is fixedly connected to the water transmission pipe 15, and the outer wall of the water transmission pipe 15 is fixedly connected to multiple fixing sections 16.

[0026] Specifically, the rinsing and dust removal tank 9 is supported and fixed by multiple bases 10. The tank body is made of corrosion-resistant PP material and can withstand a certain pressure. Multiple fixing rings 11 on the outer wall of the tank are used to reinforce the tank structure and enhance its stability. The water inlet pipe 13 is connected to the rinsing and dust removal tank 9 through the tank opening 14. After the water flows into the rinsing and dust removal tank 9, it comes into full contact with the hydrogen gas entering from the top air inlet tank 3 through the conduction pipe 12. The water washing action removes water-soluble impurities and some dust from the hydrogen gas. The conduction pipe 12 connects the rinsing and dust removal tank 9 to the purification box 1, and one end of it is connected to the transmission water pipe 15.

[0027] In this embodiment, multiple water source conduits 17 are fixedly connected to the outer walls of multiple fixed sections 16, and a diversion pipe 18 is fixedly connected to the end of the multiple water source conduits 17 away from the fixed section 16.

[0028] Specifically, the fixing joint 16 on the outer wall of the transmission water pipe 15 is used to fix and support the water source conduit 17, which flows water to the branch pipe 18, which is evenly distributed inside the purification box 1.

[0029] In this embodiment, nozzle pipes 20 are fixedly connected to the outer walls of multiple diversion pipes 18, and nozzles 19 are fixedly connected to the ends of multiple nozzle pipes 20 away from the diversion pipes 18.

[0030] Specifically, the nozzle pipe 20 and nozzle 19 connected to its outer wall can spray water evenly on the hydrogen flow path, increasing the contact area between water and hydrogen and improving the water washing and dust removal effect.

[0031] In this embodiment, a drive motor 21 is fixedly connected to one side of the outer wall of the purification box 1, and a transmission gear set 22 is connected to the output end of the drive motor 21.

[0032] Specifically, the drive motor 21 is fixed to one side of the outer wall of the purification chamber 1, and the transmission gear set 22 is composed of multiple high-precision gears, which can stably transmit the power of the drive motor 21 to the stirring rod 23. The transmission gear set 22 drives the stirring rod 23 to turn the internal catalyst.

[0033] In this embodiment, two stirring rods 23 are fixedly connected to the outer wall of the transmission gear set 22 on the side away from the drive motor 21, and both stirring rods 23 are located inside the purification box 1.

[0034] Specifically, by setting up a stirring rod 23, the internal catalyst can be agitated and fully reacted.

[0035] In this embodiment, a filter plate 24 is fixedly connected to the inner wall of the purification box 1, and the filter plate 24 is located at the top of the two stirring rods 23.

[0036] Specifically, the filter plate 24 on the inner wall of the purification chamber 1 is made of polytetrafluoroethylene microporous filter membrane with a pore size of 0.1-0.5μm, which has good chemical stability and filtration performance. The filter plate 24 is installed at the top of the stirring rod 23, which can effectively intercept solid impurities generated after the reaction and unreacted desulfurizing agent particles, and perform fine filtration of the purified hydrogen.

[0037] The working principle and usage process of this utility model are as follows: During use, hydrogen gas containing impurities such as sulfides enters the top inlet tank 3 through the inlet pipe 4. Inside the top inlet tank 3, the hydrogen gas undergoes preliminary filtration through the filter plate 7 to remove larger particles of impurities. The pre-filtered hydrogen gas then enters the rinsing and dust removal tank 9 through the conduction pipe 12. Simultaneously, water is injected into the rinsing and dust removal tank 9 through the water inlet pipe 13. The water flow and the incoming hydrogen gas come into full contact within the tank, removing water-soluble impurities and some dust through water washing. The washed hydrogen gas then enters the purification chamber 1 through the conduction pipe 12, the water transmission pipe 15, the water source conduit 17, the diversion pipe 18, and the nozzle 19. Under the action of the nozzle 19, water is sprayed into the hydrogen gas in a mist form, further improving the water washing and dust removal effect. Hydrogen gas and pre-added desulfurizing agent in purification chamber 1 are fully mixed under the stirring action of stirring rod 23. Drive motor 21 starts and drives stirring rod 23 to rotate through transmission gear set 22, so that hydrogen gas and desulfurizing agent are fully in contact, accelerating the desulfurization reaction. Sulfides react chemically with desulfurizing agent to form solid sulfide precipitates. During the reaction, filter plate 24 is located above stirring rod 23 to prevent solid impurities and unreacted desulfurizing agent particles from flowing with hydrogen gas. After sufficient reaction and stirring, sulfides in hydrogen gas are effectively removed. The reacted hydrogen gas flows upward and is finely filtered through filter plate 24 to intercept solid impurities and unreacted desulfurizing agent particles. The filtered high-purity hydrogen gas is discharged from the outlet of purification chamber 1 for subsequent use.
