Technical Field
[0001] The utility model relates to the technical field of hydrogen production by electrolyzing water, in particular to a detachable alkali spray prevention structure. Background Technique
[0002] At present, the hydrogen production system by electrolyzing water uses the gravity separation principle to separate gas and alkali liquor in the hydrogen-oxygen separator. The working temperature is about 90°C, the gas saturated vapor pressure is relatively high, and it carries a large amount of alkali liquor. Therefore, it is a key point of research to intercept as much alkali liquor as possible during the hydrogen production stage. Behind the hydrogen-oxygen separator, a scrubber, a gas cooler, a gas-water separator, etc. are set to condense and recover the alkali liquor; if the existing scrubber, gas cooler, gas-water separator and other equipment are not cleaned and maintained in time, it will lead to incomplete removal of the alkali liquor, so the alkali spray phenomenon often occurs on the oxygen side of the hydrogen production skid, which may cause potential hazards to personnel and the environment.
[0003] In the Chinese utility model patent with the publication number of CN221094305U, a hydrogen-oxygen integrated separator is disclosed. In the above-mentioned prior art, although the separation effect is improved and the separation efficiency of the separator is improved; the supporting pipeline system is simpler and the system control is more convenient, but the alkali liquor collection system in the equipment is set inside the equipment, and in the later stage of the preparation process, it is often necessary to clean and maintain. If it is not cleaned and maintained in time, it will lead to incomplete removal of the alkali liquor, so the alkali spray phenomenon often occurs on the oxygen side of the hydrogen production skid. When the staff cleans and maintains the equipment, some parts of the equipment need to be disassembled, which greatly affects the maintenance and cleaning speed and the working efficiency of the whole equipment. Therefore, it is necessary to design a detachable alkali spray prevention structure that can reduce the alkali liquor content in the early stage of preparation, reduce the pressure of the alkali liquor recovery equipment, and avoid the formation of alkali spray. Summary of the Utility Model
[0004] To solve the technical problem that the alkali spray phenomenon will occur if the alkali liquor recovery system is not cleaned and maintained in time during the preparation process, the utility model provides a detachable alkali spray prevention structure.
[0005] The utility model is realized by adopting the following technical solutions: a detachable alkali spray prevention structure, including a hydrogen-oxygen separator, a scrubber is installed on one side of the hydrogen-oxygen separator, one side of the scrubber is fixedly communicated with an oxygen pipeline, one end of the oxygen pipeline is fixedly communicated with the hydrogen-oxygen separator, and an alkali spray prevention component capable of removing alkali liquor from hot and humid gas is arranged on the oxygen pipeline. Fixed components for quickly disassembling and installing the alkali spray prevention component are arranged at both ends of the alkali spray prevention component. A docking groove is opened on the oxygen pipeline. The alkali spray prevention component includes an installation pipe arranged inside the docking groove and a wire mesh arranged inside the installation pipe.
[0006] Through the above technical solution, the anti-spray alkali component is installed on the oxygen pipeline using the fixing component, so that when the hydrogen-oxygen separator generates hot and humid gas, the alkali solution contained in the gas can be directly intercepted and removed, thereby reducing the pressure on the subsequent alkali solution recovery system.
[0007] As a further improvement of the above solution, sieve plates are provided at both ends of the wire mesh, and one of the sieve plates is fixedly installed on the inner wall of the installation pipe.
[0008] Through the above technical solution, the wire mesh will come into contact with the hot and humid gas, thereby adsorbing the alkali solution inside the gas on the wire mesh, thus reducing the overall alkali solution content of the hot and humid gas.
[0009] As a further improvement of the above solution, a plurality of sliding grooves are formed on the inner wall of the installation pipe, and a sliding block is slidably installed inside each sliding groove, and each sliding block is fixedly installed with an adjacent sieve plate.
[0010] Through the above technical solution, the sieve plate will fix and limit the wire mesh, and prevent too much debris from contacting the wire mesh.
[0011] As a further improvement of the above solution, first sealing rings are fixedly sleeved at both ends of the installation pipe, and second sealing rings fixedly sleeved with the oxygen pipeline are arranged on one side of each of the two first sealing rings. Sealing grooves are formed on one side of the two first sealing rings and the two second sealing rings, and sealing strips are arranged inside the sealing grooves of the two first sealing plates.
[0012] Through the above technical solution, the first sealing ring, the second sealing ring and the sealing strip can seal the installed installation pipe to prevent gas leakage.
[0013] As a further improvement of the above solution, a baffle fixedly installed with the two second sealing rings is arranged on one side of the installation pipe, and the baffle is arranged in an arc shape.
[0014] Through the above technical solution, the baffle will directly block the first sealing ring, so that the position of the first sealing ring will be restricted, thus facilitating quick installation.
[0015] As a further improvement of the above solution, thread grooves are formed on one side of each of the two first sealing rings. The fixing component includes a fixing block fixedly installed on one side of the second sealing ring, a fixing plate rotatably installed on one side of the fixing block, and a bolt arranged on one side of the fixing plate. One end of the bolt penetrates through the fixing plate and extends into the thread groove.
[0016] Through the above technical solution, the bolt fixes the fixing plate on the first sealing ring, and the installation pipe can be completely fixed and cannot move.
[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0018] By providing an anti-alkali spraying component and a fixing component, and installing the anti-alkali spraying component on the oxygen pipeline using the fixing component, when the hydrogen-oxygen separator generates hot and humid gas, the alkali liquid inside the gas can be directly blocked to a certain extent. Because the alkali liquid in the hot and humid gas will contact the wire mesh in the anti-alkali spraying component, it will be adsorbed on the wire mesh to a certain extent. In this way, the liquid removal load of the subsequent process can be reduced. Such a setting can not only reduce the liquid removal load of the subsequent process for the alkali liquid, but also be convenient to disassemble for cleaning and replacement.

[0024] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.
[0025] Please refer to Figures 1 - 3, A detachable anti-alkali spraying structure of this embodiment includes a hydrogen-oxygen separator 1. A scrubber 2 is installed on one side of the hydrogen-oxygen separator 1. One side of the scrubber 2 is fixedly communicated with an oxygen pipeline 3. One end of the oxygen pipeline 3 is fixedly communicated with the hydrogen-oxygen separator 1. An anti-alkali spraying component capable of removing alkali liquid from hot and humid gas is provided on the oxygen pipeline 3. Fixed components for quickly disassembling and installing the anti-alkali spraying component are provided at both ends of the anti-alkali spraying component. A docking groove is opened on the oxygen pipeline 3. The anti-alkali spraying component includes an installation pipe 401 arranged inside the docking groove and a wire mesh 402 arranged inside the installation pipe 401. Sieve plates 6 are provided at both ends of the wire mesh 402. One of the sieve plates 6 is fixedly installed on the inner wall of the installation pipe 401. A plurality of sliding grooves are opened on the inner wall of the installation pipe 401. A sliding block 7 is slidably installed inside each sliding groove. Each sliding block 7 is fixedly installed with the adjacent sieve plate 6. When the anti-alkali spraying component is installed on the oxygen pipeline 3 using the fixed component, when the hydrogen-oxygen separator 1 generates hot and humid gas, the alkali liquid contained in the gas can be directly intercepted and removed, thereby reducing the pressure on the subsequent alkali liquid recovery system. The wire mesh 402 will contact the hot and humid gas, thereby adsorbing the alkali liquid inside the gas on the wire mesh 402, thereby reducing the overall alkali liquid content of the hot and humid gas.
[0026] Combined with Figure 2 and Figure 3 , First sealing rings 8 are fixedly sleeved at both ends of the installation pipe 401. A second sealing ring 9 fixedly sleeved with the oxygen pipeline 3 is arranged in a fitting manner on one side of each of the two first sealing rings 8. Sealing grooves are opened on one side of the two first sealing rings 8 and the two second sealing rings 9. Sealing strips 10 are arranged inside the sealing grooves of the two first sealing rings 8. A baffle 11 fixedly installed with the two second sealing rings 9 is arranged on one side of the installation pipe 401. The baffle 11 is arranged in an arc shape. Thread grooves are opened on one side of the two first sealing rings 8. The fixed component includes a fixed block 501 fixedly installed on one side of the second sealing ring 9, a fixing plate 502 rotatably installed on one side of the fixed block 501, and a bolt 503 arranged on one side of the fixing plate 502. One end of the bolt 503 penetrates through the fixing plate 502 and extends into the thread groove. The first sealing ring 8 and the second sealing ring 9 cooperate with the sealing strip 10 to seal the installed installation pipe 401 to prevent gas leakage. The bolt 503 fixes the fixing plate 502 on the first sealing ring 8, so that the installation pipe 401 can be completely fixed and unable to move.
[0027] In the embodiment of the present application, the implementation principle of a detachable anti-alkali spraying structure is as follows: After the hydrogen-oxygen separator 1 generates hot and humid gas, the hot and humid gas will enter the oxygen pipeline 3 and then enter the inside of the scrubber 2. After entering the oxygen pipeline 3, it will first be filtered by the sieve plate 6, and then the gas will come into full contact with the wire mesh 402. In this way, due to the contact with the wire mesh 402, the alkali liquid inside the hot and humid gas will be adsorbed on the wire mesh 402, so that the alkali liquid content in the hot and humid gas will be reduced a lot. As a result, the pressure of the alkali liquid recovery equipment in the subsequent post-treatment process will be reduced, the number of cleaning and maintenance operations will be decreased, and the occurrence of alkali spraying can be prevented. When the wire mesh 402 needs to be cleaned due to excessive contact with the alkali liquid, only need to unscrew the bolt 503 to release the fixing effect of the fixing plate 502 on the first sealing ring 8, and then the installation pipe 401 can be removed from the oxygen pipeline 3 for cleaning and replacement. Such a setting can not only reduce the liquid removal load of the alkali liquid in the subsequent process, but also facilitate disassembly for cleaning and replacement.
[0028] The above-mentioned implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
