Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen production equipment, and in particular to an atomized photocatalytic water decomposition hydrogen production device and a use method thereof. Background Art

[0002] Existing industrial hydrogen production refers to a technology that uses non-hydride energy to produce hydrogen for industrial use through physical, chemical or biological reactions. According to the different methods and qualities of hydrogen production, industrial hydrogen production methods can be divided into three categories, namely high-temperature cracking, sodium hydrogen method and electrolysis. Among them, electrolysis is water decomposition hydrogen production technology. With the rapid development of renewable energy and the continuous growth of energy demand, hydrogen energy is a secondary energy source and is the most ideal pollution-free green energy in the new century. Therefore, it has received great attention.

[0003] In the existing technology, when using catalytic water decomposition to produce hydrogen, most of them transport water mist to the inside of the hydrogen production barrel, and then use a xenon lamp to decompose the water mist to produce gas. However, during the hydrogen production process, the water mist will be continuously transported to the inside of the hydrogen production barrel. Due to the continuous transportation of water mist, a large amount of water will adhere to the inner wall of the hydrogen production barrel and flow into the bottom of the hydrogen production barrel. When the hydrogen production barrel is maintained, the water needs to be removed, resulting in a waste of water resources. Summary of the invention

[0017] Furthermore, the method for using the atomized photocatalytic water decomposition hydrogen production device comprises the following steps:

[0019] S2: When the rotating shaft rotates, it drives the clamping rod to rotate. When the clamping rod rotates, it drives the sliding ring to rotate. When the rotating shaft rotates, the centrifugal force of the rotation speed causes the extension frame to extend in the direction away from each other. When the extension frame extends, it pushes the fixed plate to move in the direction away from each other.

[0020] S3: When the rotating shaft rotates, the threaded rod will be driven to rotate. When the threaded rod rotates, the threaded ring on the surface will move downward. When the threaded ring moves downward, the passive plate will be driven to move downward. When the passive plate moves downward, the sliding frame will be pushed to slide downward on the inner wall of the sliding groove.

[0021] S4: When water enters the inner wall of the water storage funnel, the water pump is started to pump out the water inside the water storage funnel through the water storage pipe. When the water flows into the water pump through the water storage pipe, the water is pumped into the inside of the water suction pipe through the water pump, and then the water enters the inside of the water mist disk through the water suction pipe.

[0022] The present invention has the following beneficial effects:

[0023] The present invention provides a wall scraping mechanism, firstly discharges water into the inside of the water inlet pipe, then converts the water into water mist through the water mist disk, then converts the water mist into gas through the xenon lamp, and finally starts the motor to drive the transmission shaft to rotate. When the transmission shaft rotates, it drives the rotating shaft to rotate, and when the rotating shaft rotates, it drives the clamping rod to rotate. When the clamping rod rotates, it drives the sliding ring to rotate. When the rotating shaft rotates, the centrifugal force of the rotation speed causes the extension frame to extend in the direction away from each other. When the extension frame extends, it pushes the fixed plate to move in the direction away from each other. When the fixed plate moves, it pulls the push rod to move in the direction away from each other. When the push rod moves, it drives the sliding ring to slide on the surface of the rotating shaft in the direction of approaching each other and squeezes the extension frame. When the fixed plate moves, it pushes the telescopic scraper to move in the direction away from each other and fits with the inner wall of the hydrogen production barrel. When the telescopic scraper moves, it drives the guide box to move in the direction of approaching each other, effectively scrapes off the water adhered to the inner wall of the hydrogen production barrel, and when the water flows into the bottom of the hydrogen production barrel through the cooperation of the guide groove and the guide box, the water on the inner wall of the hydrogen production barrel is cleaned.

[0024] The present invention provides a water pushing mechanism. When the rotating shaft rotates, the threaded rod is driven to rotate. When the threaded rod rotates, the threaded ring on the surface moves downward. When the threaded ring moves downward, the passive plate is driven downward. When the passive plate moves downward, the sliding frame is pushed to slide downward on the inner wall of the slide groove. When the sliding frame slides, the pushing rod is pushed to move downward. When the pushing rod is subjected to thrust, the water pushing ring is pushed to move in the direction of approaching each other on the inner wall of the hydrogen production barrel. When the water pushing ring moves, the shrinking ring is driven to move and shrink. Finally, the water is pushed into the interior of the water storage funnel, so that the cleaned water is effectively concentrated and collected.

[0025] The present invention sets a circulation mechanism. When water enters the inner wall of the water storage funnel, the water pump is started to pump out the water inside the water storage funnel through the water storage pipe. When the water flows into the water pump through the water storage pipe, the water is pumped into the inside of the water suction pipe by the water pump, and then the water enters the inside of the water mist disk through the water suction pipe. When the water enters the inside of the water mist disk, the water is converted into water mist through the water mist disk, and then the water mist is converted into gas through the xenon lamp, and finally the gas is discharged into the next process through the gas outlet pipe, so that the excess water in the hydrogen production barrel is effectively collected and recycled, which not only reduces the waste of water resources but also reduces the cost.
