[0014] A hydrogen production process using the underwater plasma generating device using high-speed airflow, the hydrogen production process comprises the following steps:

[0015] S1, extracting water from the water tank through a water pump and passing the water into the reaction chamber through a pipe;

[0016] S2, the driving motor works, the driving disc rotates, and the rotation of the driving disc causes the water in the reaction chamber to form a vortex, that is, the water flows around the central axis 2;

[0017] S3, the pneumatic pump and the electrode work, the compressed gas in the gas source tank is accelerated and diverted by the vent pipe, nozzle and diversion port, so that the compressed inert gas is accelerated and diverted, and the gas directly impacts the rotating water body at an impact angle, the electrode work generates an electric field, due to the high-speed flow of the gas and the special flow field conditions, the gas molecules are more easily ionized, thereby forming plasma, the high-energy electrons in the plasma will collide with the water molecules, the water molecules will dissociate after absorbing energy, and produce active particles such as hydrogen atoms and hydroxyl free radicals, when the drive motor works, it will also make the central axis 2 rotate, so that the thin wire will rotate to form a cutting line, the cutting line cuts the bubbles, so that the bubbles explode instantly, which can form a better energy impact and better form plasma;

[0018] S4. The mixed gas generated by the reaction in the reaction chamber will enter the separation chamber through the connecting pipe. The separation membrane in the separation chamber will separate the hydrogen and the inert gas, and the purification filter element will absorb the water vapor and impurities in the hydrogen, thereby purifying the hydrogen;

[0019] S5. The vacuum pump works to make the gas tank into a vacuum state, so that the hydrogen separated and purified in the separation chamber will enter the gas tank and be stored, while the inert gas left after separation will remain in the separation chamber. At this time, the booster pump works to extract the inert gas in the gas separation chamber, and use the recovery box to recover and pressurize the inert gas for storage.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] During use, the present invention utilizes ultra-high-speed airflow to directly impact water flow, which can accelerate the generation of plasma, greatly accelerate the generation of plasma, thereby improving the production efficiency of hydrogen, and the present invention has a simple process flow, high working efficiency, low energy consumption, and good hydrogen production effect.

[0022] During use, the present invention is conducive to the mutual cooperation between the vent pipe and the nozzle, and can accelerate the airflow so that the gas flow rate reaches supersonic speed. In this way, the water body that uses the gas to impact the vortex can better generate bubbles, so that the water body can be better plasmatized and plasma can be generated more efficiently. The setting of the diverter block and the diverter port can divert the airflow, and the dispersed high-speed airflow can impact more water bodies. The Laval tube setting of the diverter port can further accelerate the airflow, and the operation is efficient.

[0023] The present invention utilizes the arrangement of a driving disk and a protruding plate, and during use, the water in the reaction chamber is moved to form a vortex, so that the water is impacted by the high-speed airflow in a flowing state. When the high-speed airflow forms a local low-pressure area and strong turbulence in the water, the electrodes in this area will generate a high-frequency electric field. Due to the high-speed flow of the gas and the special flow field conditions, the gas molecules are more easily ionized, thereby forming plasma. At the same time, bubbles are generated when the airflow impacts the water, and the bubbles are swept and exploded by the thin wire, forming an instantaneous force acting on the water, which is conducive to the generation of plasma and greatly improves the work efficiency. In addition, the arrangement of the water-cutting blade can help the vertical bar cut the water, thereby greatly reducing the resistance of the vertical bar rotating in the water, and helping the vertical bar to rotate at a high speed in the water, thereby ensuring that the thin wire can quickly cut the bubbles.

[0024] During use of the present invention, a separation membrane is used to separate inert gas and hydrogen, and the hydrogen is filtered by a purification filter element. In this way, the gas stored in the gas storage tank is high-purity hydrogen, and the inert gas and water vapor are stored in a recovery box. When the gas pressure in the gas source tank is reduced and the amount used is reduced, the inert gas and water vapor recovered in the recovery box can also be used. In this way, the inert gas can be reused, energy is saved, and it is easy to use.

[0025] The present invention adopts a split arrangement of the disassembly cover and the separation chamber, and the fixing frame is fixed in the separation chamber by the disassembly cover. The staff can quickly disassemble and assemble the disassembly cover, thereby taking out the two fixing frames from the separation chamber. The staff can quickly replace the separation membrane and the purification filter element manually, which reduces the workload of the staff and is easy to use.

[0026] The present invention facilitates workers to replace thin wires through the mutual cooperation of the pulling block, the top block, the bearing three, the threaded rod and the rotating disk. When the thin wires are bolted, it is not necessary to fully tighten the thin wires. After the thin wires are bolted, the threaded rod is rotated by the rotating disk, and the middle part of the thin wires is pulled upward by the pulling block, so that the thin wires are tightened. This makes it easier to operate during installation, reduces the operating burden of the workers, and is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

The high-energy electrons in the plasma will collide with the water molecules, and the water molecules will dissociate after absorbing energy to produce active particles such as hydrogen atoms and hydroxyl free radicals. The mixed gas in the reaction chamber 1 will enter the separation chamber 32 through the connecting pipe 34, and the automatic valve on the exhaust pipe 65 will be closed, and the vacuum pump 42 performs vacuum treatment on the gas storage tank 41, and then the automatic valve on the generating pipe 40 is opened. In the mixed gas in the separation chamber 32, the helium will be blocked by the separation membrane 36, and the purification filter element 37 will block the water vapor. In this way, the gas is processed by the separation membrane 36 and the purification filter element 37, and the gas entering the gas storage tank 41 is clean hydrogen. The automatic valve on the generating pipe 40 is closed, and the automatic valve on the exhaust pipe 65 is opened. The booster pump 39 works, so that the residual gas in the separation chamber 32 will enter the recovery box 38. At this time, the automatic valve on the recovery pipe 66 is closed. When there is no gas available in the gas source tank 7 or the pressure is reduced, the automatic valve on the recovery pipe 66 can be opened to use the mixed gas recovered in the recovery box 38. The gas enters the gas source tank 7 and is reused. The threaded rod 54 is rotated by the rotating disk 55, and the threaded rod 54 moves upward. The threaded rod 54 drives the top block 52 to move upward through the bearing three 53. The top block 52 pulls the thin wire 22, which is beneficial to tighten the thin wire 22 (this also makes it possible to not tighten the thin wire 22 when bolting). The buckle 57 is bendable to separate the buckle 57 from the block 58, and then the disassembly cover 33 moves upward. The disassembly cover 33 drives the stabilizing rod 63 to detach from the separation chamber 32, and the driven rod 61 and the pressure plate 59 move to the outside of the separation chamber 32. After that, the fixed frame 35 is pulled upward by the disassembly block 60, so that the fixed frame 35 can be removed from the separation chamber 32, which is beneficial to the replacement of the separation membrane 36 and the purification filter element 37.

At this time, the booster pump (39) operates to extract the inert gas in the gas separation chamber (32), and the recovery box (38) is used to recover and pressurize the inert gas for storage.
