Problems solved by technology

The reason is that it is difficult to prepare cheap and high-purity hydrogen; the storage and transportation of hydrogen have not been effectively solved, especially in special environments such as battlefields, fields, remote areas, and disaster areas. It is even more difficult to obtain hydrogen on site
Although some metals or metal hydrides, such as aluminum, magnesium, calcium hydride, sodium borohydride, etc., can react with water to produce hydrogen relatively easily, but the hydrogen production process is difficult to control, and some of them need to store the produced hydrogen under high pressure. Not convenient for mobile use
[0003] Therefore, the existing hydrogen production device cannot solve the problem of reliable hydrogen supply for portable hydrogen equipment such as fuel cells in an emergency environment

Embodiment 1

[0046] combined with figure 1 b The structure of the gas generating device in the dynamic self-balancing gas generating device provided by the present invention is stated in detail as follows: the device includes a gas generating tank 6, a material bin 4, a gas outlet 3, a gas collecting hood 5 and a gas pressure regulating port 1; The gas collecting hood 5 is arranged inside the gas generating tank 6, the bottom end of which is connected to the bottom end of the gas generating tank 6, and the top is airtightly connected with the top cover of the gas generating tank 6; the material bin 4 is a permeable mesh structure embedded Set inside the gas collecting hood 5, there is a gap between the outer side wall and the outer bottom wall of the gas collecting hood 6, the inner side wall and the bottom of the gas collecting hood 6, the top of the material bin 4 is airtightly connected with the top cover of the gas generating tank, so that the metal material and the gas The auxiliary a...

Embodiment 2

[0052] attached to figure 1 Add 240g of sodium hydroxide and 620g of water into the gas generating tank shown in a; add 80g of aluminum raw material with an average diameter of 1mm into the material bin, which is a 30-mesh polytetrafluoroethylene mesh, and the two react to generate hydrogen. After 1 minute, the hydrogen gas starts to be delivered, and after 3 minutes, the system tends to be stable, after which the reaction of the device is automatically adjusted. The hydrogen output rate was kept between 1 and 1.5 L / min within 10 to 60 minutes, and the reaction was terminated after 90 minutes.

[0053] When the hydrogen-requiring equipment stops working, close the gas outlet 3, the gas supply is completed, and at the same time open the gas pressure regulating port 1 and the feeding port 2, and directly open the gas generating tank to discharge the waste liquid.

Embodiment 3

[0055] Add 150g of sodium hydroxide to the attached figure 1 Add 700g of water to dissolve the gas generating tank shown in b; add 50g of aluminum raw material, with an average diameter of 0.6mm, into the material bin, which is made of 40-mesh stainless steel mesh, and the two react to generate hydrogen. After 1 minute, the hydrogen gas starts to be delivered, and after 3 minutes, the system tends to be stable, after which the reaction of the device is automatically adjusted. The hydrogen output rate was kept between 1 and 1.5 L / min within 10 to 35 minutes, and the reaction was terminated after 40 minutes.

[0056] When the hydrogen-requiring equipment stops working, close the gas outlet 3, the gas supply is completed, and at the same time open the gas pressure regulating port 1 and the feeding port 2, and directly open the gas generating tank attachment figure 1 b Bottom drain port 9 to discharge waste liquid.

Description

technical field [0001] The invention relates to the technical field of gas generation, in particular to a dynamic self-balancing gas generating device and a use method thereof. Background technique [0002] Due to the gradual depletion of fossil energy and the increasingly serious environmental problems, my country and many countries in the world have listed the development and research of hydrogen energy technology and fuel cells as a strategic goal of sustainable development. The current fuel cell technology is about to be put into practical use, but the source and supply of hydrogen has always been one of the key factors restricting the application and promotion of fuel cells. The reason is that it is difficult to prepare cheap and high-purity hydrogen; the storage and transportation of hydrogen have not been effectively solved, especially in special environments such as battlefields, fields, remote areas, and disaster areas. It is even more difficult to obtain hydrogen o...
