Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen production equipment, in particular to a hydrogen production equipment with a drying structure. Background Technique

[0002] Hydrogen production equipment refers to equipment that can produce hydrogen. Generally, through the method of electrolyzing water, hydrogen and oxygen in water are separated to obtain pure hydrogen.

[0003] When using an electrolytic hydrogen production machine to prepare hydrogen, water is put into the electrolytic hydrogen production machine, and then the electrolytic hydrogen production machine is started to make the water undergo an electrolysis reaction in two chambers. The electrolyzed water will produce hydrogen ions and oxygen ions. When the hydrogen ions contact the electrolytic rod connected to the negative electrode, they will receive electrons in the cathode to generate hydrogen, while the oxygen ions will lose electrons in the anode when contacting the electrolytic rod connected to the positive electrode to generate oxygen. The generated hydrogen and oxygen will respectively enter the anti-backfire tank through the first delivery pipe, and then enter the hydrogen storage tank and the oxygen storage tank through the second delivery pipe respectively for storage, making the hydrogen production successful. The prepared hydrogen may contain a small amount of water vapor. To avoid the relatively wet hydrogen affecting the use, a molecular sieve barrel is usually installed between the inlet of the hydrogen storage tank and the second delivery pipe for drying treatment. After the molecular sieve in the molecular sieve barrel is used for a long time, the molecular sieve inside may be damaged, reducing the drying efficiency. The daily replacement generally requires first turning off the electrolytic hydrogen production machine and suspending the hydrogen production operation, and then disassembling both the second delivery pipe and the inlet of the hydrogen storage tank from the molecular sieve barrel to replace the whole molecular sieve barrel. Such operation steps are more and the operation is more cumbersome, reducing the replacement efficiency and also reducing the hydrogen production efficiency. Summary of the Utility Model

At this time, the block 28 is inserted into the inner wall of the hole block 26 and the slot 27 to limit it, and then the used round tube block 29 and molecular sieve 210 are pulled out from the circular groove 24, so that the replacement is completed, which is convenient for the next replacement operation. By doing so, the round tube block 29 and the molecular sieve 210 can be replaced without shutting down the electrolytic hydrogen generator 4. The operation steps are relatively simple and easy to operate, thereby improving the replacement efficiency and hydrogen production efficiency.

[0036] Working principle: When using the electrolytic hydrogen generator 4 to produce hydrogen, water is put into the interior of the electrolytic hydrogen generator 4, and then the electrolytic hydrogen generator 4 is started, causing the water to undergo an electrolysis reaction in two chambers. After electrolysis, the water will produce hydrogen ions and oxygen ions. When the hydrogen ions contact the electrolytic rod connected to the negative electrode, they will receive electrons in the cathode to generate hydrogen, while the oxygen ions will lose electrons in the anode when they contact the electrolytic rod connected to the anode to generate oxygen. The generated hydrogen and oxygen will respectively enter the backfire prevention tank 6 through the first delivery pipe 5, and then be transported to the inner walls of the round pipe rack 21 and the round pipe block 29 through the second delivery pipe 7. After being dried by multiple molecular sieves 210 for hydrogen and oxygen, they will respectively enter the hydrogen storage tank 8 and the oxygen storage tank 9 for storage, achieving successful hydrogen production. When the molecular sieve 210 is damaged after long-term use, first manually insert the round pipe block 29, the molecular sieve 210, and the slider 212 that need to be replaced into one of the round grooves 24 and the slider 212 respectively. Then manually pull out the clamping block 28 from the clamping hole block 26 and the clamping groove 27. Then hold the rotating block 23 and rotate it in the first groove 22 to a certain angle, so that the end with the new round pipe block 29 and the molecular sieve 210 is rotated to the inner wall of the round pipe rack 21, while the used round pipe block 29 and the molecular sieve 210 are rotated out. At this time, insert the clamping block 28 into the inner walls of the clamping hole block 26 and the clamping groove 27 to limit it, and then hold the pulling block 211 to pull out the used round pipe block 29 and the molecular sieve 210 from the round groove 24 to complete the replacement, facilitating the next replacement operation. Through such an operation, the round pipe block 29 and the molecular sieve 210 can be replaced without shutting down the electrolytic hydrogen generator 4. The operation steps are relatively simple and convenient to operate, improving the replacement efficiency and hydrogen production efficiency.

[0037] When the round pipe rack 21 is damaged and needs to be replaced, you can manually hold the screwing block 37 and screw the threaded hole block 36 on the threaded rod 35 towards one end to a certain position, so that one side of it moves away from one side of the ring block 31 to release the abutment. At this time, then rotate the threaded rod 35 around one end in the U-shaped block 34 in a circular motion to a certain angle to rotate it out. Finally, you can first pull out the second delivery pipe 7 from the installation groove 33 at one end of the round pipe rack 21, and then pull the round pipe rack 21 upward to pull out the inlet of the hydrogen storage tank 8 from the installation groove 33 at the other end of the round pipe rack 21 to disassemble the round pipe rack 21, facilitating its replacement.
