Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of solid-state hydrogen storage and nitrogen gas mixed storage device technical field, specifically to a kind of solid-state hydrogen storage and nitrogen gas mixed storage device. BACKGROUND

[0002] With the development of science and technology, the products of ammonia synthesis are also more and more widely used in various fields. As we all know, synthetic ammonia is synthesized by nitrogen and hydrogen at high temperature, high pressure and catalyst. Industrial synthesis of ammonia has great significance to human activities, and in the face of the gradual intensification of greenhouse effect, ammonia is regarded as a sustainable fuel. On the one hand, ammonia, as a hydrogen-rich substance, is an ideal carrier of hydrogen energy. On the other hand, ammonia combustion can achieve zero carbon emission and can replace traditional fuels. In addition, ammonia is suitable for transportation to meet some energy needs of liquefied natural gas, including electricity, transportation, heating, etc. Therefore, ammonia can be used as a working medium to store distributed energy, and then long-distance transportation can convert energy into stable electricity for delivery to the user end. In the existing ammonia synthesis process technology, a double-gas channel is often used to store hydrogen and nitrogen separately, and then further mix before the synthesis reaction. The storage and transportation of hydrogen is a limiting link in the hydrogen energy industry chain. Improving the efficiency and reducing the cost of hydrogen energy storage and transportation is the key to the development of hydrogen energy storage and transportation technology.

[0003] Currently, there are three main ways of hydrogen storage in practical use: high-pressure gaseous hydrogen storage, cryogenic liquid hydrogen storage tanks, and solid-state hydrogen storage based on hydrogen storage materials. Solid-state hydrogen storage technology uses the reaction between hydrogen and hydrogen storage materials to store hydrogen. The principle of solid-state hydrogen storage is essentially a chemical hydrogen storage method. The mechanism is that under certain conditions, hydrogen atoms can easily enter the tetrahedral or octahedral interstitial sites of the metal lattice. These metal alloys react with hydrogen to form metal hydrides, which can store hydrogen equivalent to 1000-3000 times their volume. These alloys with hydrogen storage capacity are called "hydrogen storage alloys". The absorption and release of hydrogen by hydrogen storage alloys is a reversible process. During the absorption of hydrogen, the hydrogen storage alloy releases a large amount of heat. If the heat is not quickly dissipated, it will affect the hydrogen absorption process, causing the local temperature of the hydrogen storage alloy to be too high and causing partial aging failure.
