[0002] Hydrogen energy is an important carrier for achieving green and low-carbon transformation, so it has broad prospects in the future "dual carbon" market. Hydrogen is a clean and efficient secondary energy source. There is very little elemental hydrogen on the earth, and it must be converted from other compounds. There are currently four main ways to produce hydrogen: hydrogen from fossil fuels, hydrogen from industrial byproducts, hydrogen from water electrolysis, and hydrogen from biomass. However, with the approach of the "dual carbon" goal and the deepening of the scientific concept of sustainable development, using water (H2O) as a source of hydrogen is undoubtedly more extensive and environmentally friendly. Therefore, water electrolysis hydrogen production technology has gradually become a widely promoted hydrogen production technology. However, since water electrolysis hydrogen production requires high voltage and high current as well as high power consumption, it has the disadvantages of high hydrogen production cost, complex equipment and environmental pollution, and still cannot become an ideal hydrogen production technology and green hydrogen technology.

[0019] The specific embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments, and any improvement or substitution based on the basic spirit of the present embodiment still falls within the scope of protection required by the claims of the present invention.

[0020] Example 1: Figure 1 , 3As shown, a hydrogen production device by hydrolysis of external loading includes a water tank 1 and a hydrogen production reaction tank 2, wherein the water tank 1 is connected to the hydrogen production reaction tank 2 via a water inlet pipe 3, and a material tank 4 connected to the hydrogen production reaction tank 2 is arranged above the hydrogen production reaction tank 2; a hydrogen purification tank 6 connected to the hydrogen production reaction tank 2 via a pipeline A5 is arranged on one side of the hydrogen production reaction tank 2, and a buffer air bag tank 11 connected to the hydrogen purification tank 6 via a vertical pipeline 7 is arranged above the hydrogen purification tank 6; the vertical pipeline 7 is sequentially connected to a filter 9 and a dryer 10 via a horizontal pipeline 8 with a switch valve 36.

[0021] The buffer airbag tank 11 includes a tank body, a buffer airbag 12 is arranged in the tank body, a spring-type air-blocking valve 13 is arranged on the top of the tank body, and the buffer airbag 12 is connected to the vertical pipeline 7.

[0022] In order to facilitate the recovery of hydrogen production materials, a material recovery barrel 14 is provided below the hydrogen production reaction tank 2 .

[0023] The material tank 4 is connected to the hydrogen production reaction tank 2 via a solenoid valve A25 ; a solenoid valve B26 is provided at the lower end of the hydrogen production reaction tank 2 .

[0024] In order to control the water inlet, a water pump 27 is provided on the water inlet pipe 3 .

[0025] Furthermore, a one-way valve A28, a one-way valve B29 and a one-way valve C30 are respectively provided on the water inlet pipe 3, the pipeline A5 and the horizontal pipeline 8.

[0026] In the present invention, the material used for producing hydrogen is an aluminum-containing composition or an aluminum-based composite alloy.

[0027] The present invention works as follows: the solenoid valve A25 is opened, and the hydrogen production material particles in the material tank 4 flow into the hydrogen production reaction tank 2 like sand in an hourglass, and then the solenoid valve A25 is closed. The hydrogen production material has the characteristics of spontaneous hydrolysis and hydrogen production at room temperature and pressure with zero electricity and zero energy consumption. Therefore, after more than ten seconds, spontaneous hydrogen production begins, and the hydrogen automatically gathers at the upper part of the hydrogen production reaction tank 2. When the generated hydrogen gathers to form a certain pressure, the hydrogen flows into the hydrogen purification tank 6 through the pipeline A5 and the one-way valve A28, and the hydrogen flows out from the pipeline port at the bottom of the tank, passing through the tank. The cooled and purified reclaimed water is then gathered at the top of the purification tank 6; first, the hydrogen flows into the buffer airbag 12 of the buffer airbag tank 11 through the vertical pipeline 7. After the buffer airbag 12 is inflated and expanded, the top of the buffer airbag 12 rises and touches the spring-type air-closing valve that pushes upward until the valve is closed. The excess or over-pressure hydrogen is buffered into the buffer airbag and pressure is formed. At this time, the switch valve 36 is opened, and the compressed hydrogen flows through the filter 9 and the dryer 10 through the one-way valve C30 and flows into the direct hydrogen user end for use, achieving immediate use.

[0028] After each round of hydrogen production is completed, the solenoid valve B26 below the hydrogen production reaction tank 2 is opened to release the wastewater produced by the reaction. After being filtered by the embedded filter screen in the material recovery barrel, the water leaks into the bottom of the recovery barrel, and the particles of the reaction products are filtered and separated by the filter screen.

[0029] Further description, in the present invention, the spring-type air-locking valve 13 includes an air-locking valve outer shell 15, a bottom tray 16 is arranged below the air-locking valve outer shell 15, a switch column 17 is vertically arranged on the bottom tray 16, and a spring 18 is sleeved on the switch column 17; an accommodating cavity 19 is arranged inside the air-locking valve outer shell 15, a hemispherical concave groove 20 that cooperates with the upper part of the switch column 17 is arranged above the accommodating cavity 19, and a venting hole 21 is arranged at the upper part of the hemispherical concave groove 20.

[0030] In the present invention, hydrogen enters into the cushion airbag 12, the cushion airbag 12 is inflated, the top of the cushion airbag 12 is pressed against the bottom tray 16, and then the spring 18 is compressed, so that the top of the switch column 17 enters into the hemispherical concave groove 20, blocks the vent hole 21, and cuts off the connection between the cushion airbag tank 11 and the outside.

[0031] When the hydrogen in the buffer airbag 12 is discharged, the buffer airbag 12 no longer presses against the spring-loaded air-locking valve 13 , the air release hole opens, and the external atmosphere enters the buffer airbag tank 11 to balance its air pressure.

[0032] When the amount of hydrogen is not very large, the pressure of the hydrogen is not large enough to expand the buffer airbag 12 to touch and push the spring-loaded air-locking valve 13 to move upward to close. In this range of hydrogen amount, the spring-loaded air-locking valve 13 is always in a normally open state, and the external atmosphere can freely enter and exit the buffer airbag tank 11 through the spring-loaded air-locking valve 13. When the buffer airbag 12 is filled with hydrogen, the buffer airbag 12 expands, and the air in the buffer airbag tank 11 is discharged from the buffer airbag tank 11 through the spring-loaded air-locking valve 13. When the amount of hydrogen decreases, the tension of the buffer airbag 12 will squeeze the hydrogen out of the buffer airbag 12, the volume of the buffer airbag 12 is reduced, and the atmosphere outside the buffer airbag tank 11 can freely flow into the buffer airbag tank 11 through the normally open spring-loaded air-locking valve 13. Within such a range of hydrogen amounts, as hydrogen rushes into the cushion airbag 12 and expands, the gas in the cushion airbag tank 11 flows out freely; as hydrogen decreases, the cushion airbag 12 contracts, and the gas outside the cushion airbag tank 11 flows into the cushion airbag tank 11 freely. The free expansion and contraction of the cushion airbag 12 regulates and buffers the generation and reduction of excess hydrogen.

[0033] When the amount of hydrogen generated is large enough to make the cushion airbag 12 expand to touch and push the spring-type air-closing valve 13 upward to close, the gas in the cushion airbag tank 11 has been squeezed out of the cushion airbag tank 11 before the valve closes. At this time, the skin of the cushion airbag 12 is tightly attached to the inner wall of the cushion airbag tank 11. The cushion airbag 12 has no more space to expand. At this time, the pressure generated by the extra hydrogen rushing into the cushion airbag 12 is transmitted to the tank wall of the cushion airbag tank 11 through the skin of the cushion airbag 12. The cushion airbag tank 11 is generally made of stainless steel, and its durability is much higher than that of the cushion airbag 12. The extra hydrogen in the cushion airbag 12 forms a high-pressure state due to the pressure support generated by the tank wall, and the high pressure forms a larger amount of hydrogen storage. As long as the gas pressure in the cushion airbag 12 does not exceed the compressive strength of the wall of the cushion airbag tank 11, the cushion airbag 12 can still store a large amount of gas and play a cushioning role under high pressure; it can freely buffer and release a large amount of stored hydrogen, which improves the safety of use.

[0034] Example 2: Figure 2 As shown, a compressor 22 and a hydrogen storage bottle 23 are provided on one side of the dryer 10, the dryer 10 is connected to the compressor 22, and the compressor 22 is connected to the hydrogen storage bottle 23 through a pipeline B24. This is done for the convenience of storing excess hydrogen and for the convenience of moving and transporting the hydrogen after it is stored in the hydrogen storage bottle 23.

[0035] Further description, an electromagnetic switch valve A31 and a pressure reducing valve 32 are arranged at the inlet of the hydrogen storage bottle 23, and the electromagnetic switch valve A31 is connected to the pipeline B24 through the air inlet pipe 33, and a pressure gauge 34 and a one-way valve D35 are arranged on the air inlet pipe 33. When the pressure in the hydrogen storage bottle 23 is too high, the pressure can be reduced by the pressure reducing valve 32; when the compressor 22 delivers hydrogen to the hydrogen storage bottle, the hydrogen pressure can be read by observing the value on the pressure gauge 34.

[0036] In order to facilitate the delivery of hydrogen to customers, a pipeline C37 is provided on the pipeline B24, and a one-way valve E38 and an electromagnetic switch valve B39 are sequentially provided on the pipeline C37.
