Description

Technical Field

[0001] This utility model relates to the field of hydrogen scrubbing technology, specifically to a spray-type hydrogen separation scrubber. Background Technology

[0002] Hydrogen and oxygen, separated from the hydroelectric process, are carried along with alkaline solution and enter a hydrogen separator and an oxygen separator, respectively. In the hydrogen separator, the hydrogen is separated from the entrained alkaline solution. The separated hydrogen then enters a hydrogen scrubber, where the hydrogen containing alkaline mist passes through a pure water medium to form bubbles. As the bubbles rise, impurities such as alkaline mist in the hydrogen come into full contact with the liquid and are absorbed or reacted to remove them, thus achieving the purpose of washing the hydrogen.

[0003] In existing hydrogen separators, some impurities that are insoluble in liquid media and do not react chemically with liquids, such as some solid particulate impurities, will enter the scrubber along with the gas for washing. However, the scrubber is not effective in removing these impurities, and the gas is unevenly distributed in the hydrogen separator, resulting in a limited gas-liquid contact area and affecting the washing effect.

[0004] Furthermore, the scrubber connected to the outlet of the hydrogen separator is equipped with an overflow port. Excess liquid overflows back into the separator. However, due to pressure, the overflow port may cause liquid in the separator to flow back into the scrubber, affecting the washing effect. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a spray-type hydrogen separation and scrubbing device with simple structure, low manufacturing difficulty, and good washing effect.

[0006] To solve the above-mentioned technical problems, this utility model provides a spray-type hydrogen separation and scrubbing device, including a separator. The separator has an alkaline outlet at the bottom, a gas outlet at the top, and a gas inlet on one side. The alkaline outlet and the gas inlet are both connected to an electrolytic cell. The gas outlet is connected to a scrubbing device. The scrubbing device has a hydrogen outlet at the top. A sprayer is installed inside the scrubbing device. A first structured packing is installed below the sprayer. The first structured packing includes several layers of corrugated mesh stacked together. The mesh openings between adjacent layers of corrugated mesh are staggered. At least one layer of corrugated plate is installed in the first structured packing. The corrugated plate has mesh openings. An external pipe is installed between the sprayer and the scrubbing device.

[0007] Furthermore, the porosity of the corrugated plate is less than that of the corrugated mesh.

[0008] Furthermore, the corrugated mesh is fixed to the corrugated plate by welding, and the first structured filler is fixed to the inner wall of the washer by welding.

[0009] Furthermore, a second structured packing is provided below the first structured packing. The first and second structured packings have the same structure and are separated by a space. An annular guide shroud is provided on the inner wall of the washer corresponding to the space. The annular guide shroud is trumpet-shaped and its large end faces the first structured packing.

[0010] Furthermore, at least two locking through holes are uniformly provided on the first structured packing, and a connecting bolt is provided in the locking through hole. The bolt head of the connecting bolt abuts against the surface of the first structured packing, and the thread of the connecting bolt passes through the locking through hole and is threadedly connected to the mounting lug. The mounting lug is fixed to the inner wall of the washer.

[0011] Furthermore, a rubber sealing sleeve is provided inside the locking through hole, and the connecting bolt passes through the rubber sealing sleeve.

[0012] Furthermore, the air outlet is connected to the scrubber via a flange.

[0013] Furthermore, the sprayer has a lotus-shaped structure.

[0014] The beneficial effects of this utility model are:

[0015] 1. Excellent washing effect: Pure water is evenly sprayed onto the surface of the first structured packing material through a lotus-shaped sprayer, and the corrugated mesh effectively locks in the water. This allows for comprehensive, multi-angle washing, effectively removing various impurities and solid particles that are insoluble in the liquid medium and do not chemically react with it. The corrugated plate provides good support, preventing collapse due to the weight of the liquid within the mesh, and further enhances the water-locking effect, preventing excessive liquid loss from the first structured packing material.

[0016] 2. Safer: There is no need to install an overflow port between the washer and the separator. The liquid can directly enter the separator, eliminating the situation where the liquid will flow back into the washer due to pressure in the separator.

[0017] 3. The pure water in the scrubber can be recycled. While spraying and washing, the pure water passes directly into the separator through the scrubber and is then added to the electrolytic cell for electrolysis. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0023] Reference Figures 1 to 3 As shown, one embodiment of the spray-type hydrogen separator and scrubber of this utility model includes a separator 1, with an alkaline outlet 2 at the bottom, an air outlet 3 at the top, and an air inlet 4 on one side. Both the alkaline outlet and the air inlet are connected to an electrolytic cell 5. The air outlet is connected to a scrubber 6. A hydrogen outlet 7 is located at the top of the scrubber. A sprayer 8 is installed inside the scrubber. The sprayer has a lotus-shaped structure, capable of uniformly supplying pure water. A first structured packing 9 is installed below the sprayer. The first structured packing includes several layers of stacked corrugated mesh 10, with staggered mesh openings between adjacent layers. At least one corrugated plate 11 is installed in the first structured packing, with mesh openings 12 on the corrugated plate. An external pipe 13 connects the sprayer and the scrubber. The air outlet is connected to the scrubber via a flange 20, making operation convenient and reliable. It does not have an overflow structure and facilitates the assembly of the first structured packing.

[0024] In use, the scrubber is connected to the separator via a connecting flange. Pure water continuously enters the lotus-shaped sprayer through the external pipe of the water inlet. The lotus-shaped sprayer has many small holes, which allows the pure water to be sprayed out in a diffused manner, evenly spraying downwards onto the first layer of structured packing composed of corrugated mesh and corrugated plates. The pure water flows downwards through the mesh holes of the corrugated mesh and corrugated plates due to gravity. Due to the staggered arrangement of the corrugated mesh holes, its flow direction also moves laterally, thus filling the mesh holes of the multi-layer structure and playing a water-retaining role. Finally, it flows into the separator and mixes with the alkaline solution in the separator. Then, it enters the electrolytic cell through the alkaline solution outlet for electrolysis, thereby achieving the purpose of replenishing pure water.

[0025] The mixture of hydrogen gas and alkali solution released from the electrolytic cell enters the separator through the inlet. Due to gravity, the hydrogen and alkali solution separate in the separator, with the alkali solution remaining. This mixture then mixes with the alkali solution in the separator and re-enters the electrolytic cell through the alkali solution outlet for further electrolysis. The hydrogen gas, mixed with the mist-like alkali solution, enters the scrubber through the outlet. After entering the scrubber, it rises into the first layer of structured packing. Under the action of the corrugated mesh and corrugated plates, pure water is evenly distributed in the first layer of structured packing. Meanwhile, the alkali-containing hydrogen gas is dispersed by the mesh openings and moves evenly upwards, passing through the channels formed by the mesh openings. Since each channel contains pure water, this increases the contact area between the alkali-containing hydrogen gas and the pure water in the first layer of structured packing. Upon contact with the pure water, the alkali in the hydrogen gas is absorbed and remains in the first layer of structured packing. The gas is then washed, purified, and discharged after passing through the first layer of structured packing, while the alkali-absorbing pure water flows downwards into the separator due to gravity. The washed hydrogen gas is discharged from the outlet and enters the downstream equipment.

[0026] In summary, the corrugated mesh and corrugated plates in the first layer of structured packing effectively form crisscrossing channels, allowing pure water to flow evenly through and out of these channels. This ensures that the gas remains in constant contact with the pure water, achieving a good washing effect, and preventing the pure water from flowing away too quickly, thus maintaining a constant supply of pure water within the channels. The porosity of the corrugated plate mesh is lower than that of the corrugated mesh, further reducing the flow velocity of the pure water and allowing for a more complete reaction between the gas and the pure water.

[0027] The corrugated mesh and corrugated plate are fixed together by welding to form an integral whole, and the first structured filler is fixed to the inner wall of the washer by welding. The preparation is simple and reliable.

[0028] To further improve the washing effect, a second structured packing 14 can be installed below the first structured packing. The first and second structured packings have the same structure and are separated by a space. An annular guide hood 15 is installed on the inner wall of the washer corresponding to the space. The annular guide hood is funnel-shaped with its larger end facing the first structured packing. Alkaline hydrogen gas is first washed by the second structured packing before entering the first structured packing, thus improving the washing effect. Since the first structured packing does not achieve complete contact with the inner wall of the washer, pure water may flow quickly through the inner wall, and pure water on the inner wall may also flow between the second structured packing and the inner wall, resulting in a reduction of pure water on the surface of the second structured packing. Therefore, by setting up the annular guide hood, the pure water flowing between the first structured packing and the inner wall of the washer is guided to converge towards the surface of the second structured packing, thereby ensuring the amount of pure water in the second structured packing.

[0029] In one embodiment, when the first and second structured packings are damaged, disassembly is difficult due to their welded fixing, and the entire packing needs to be replaced. Therefore, a detachable and replaceable structure is provided. Specifically, refer to... Figure 4 As shown, at least two locking through holes are evenly arranged on the first structured packing. A connecting bolt 17 is installed in the locking through hole. The bolt head of the connecting bolt abuts against the surface of the first structured packing. The bolt thread passes through the locking through hole and is threadedly connected to the mounting lug 18. The mounting lug is fixed on the inner wall of the washer.

[0030] The connecting bolts press the multi-layered structure onto the mounting lugs, thus creating axial restraint. The engagement of the connecting bolts with the locking through-holes also provides radial restraint, securely locking the multi-layered structure together. Disassembly is simple; just separate the connecting bolts from the mounting lugs. This convenient operation allows for replacement of each layer, significantly reducing maintenance costs. Furthermore, the corrugated plate's strength effectively supports the multi-layered corrugated mesh, ensuring overall strength after installation. The second structured packing uses the same installation method as the first structured packing, achieving quick assembly and disassembly. The mounting lugs for the second and first structured packings can be staggered for easy locking and reduced interference.

[0031] A rubber sealing sleeve 19 is also provided inside the locking through hole. The connecting bolt passes through the rubber sealing sleeve, and the rubber sealing sleeve can effectively contact the inner wall of the locking through hole to form a seal, effectively preventing pure water from flowing directly out of the locking through hole.

[0032] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
