Solid metal alloy hydrogen storage bottle

Abstract

The invention relates to the technical field of storage equipment, in particular to a solid metal alloy hydrogen storage bottle. The bottle comprises a bottle body, a gas collecting device for conveying hydrogen and a heat exchange device for providing a circulating heat exchange medium are arranged on the bottle body, a plurality of hydrogen storage alloys are arranged in the bottle body, a plurality of flow dividing pull pipes connected to the gas collecting device are further arranged between the hydrogen storage alloys, and a flow dividing opening is formed in each flow dividing pull pipe so that hydrogen can evenly flow out to the position of each hydrogen storage alloy. By improving a storage structure of the hydrogen storage alloys in the bottle body, the hydrogen storage shell pass and the heat exchange shell pass in the bottle body are reasonably arranged, hydrogen can be effectively guided to enter and be released, the flow direction of the heat exchange medium can be effectively guided, and sufficient absorption and release of hydrogen and rapid exchange and transfer of heat are achieved. The whole hydrogen storage bottle is more reasonable in structure, internal and external stress is reduced in the hydrogen absorption and release process, the hydrogen absorption and release process is more efficient and sufficient, heat transfer is more uniform, and the hydrogen storage mass ratio is increased.

Description

technical field [0001] The invention relates to the technical field of storage equipment, in particular to a solid metal alloy hydrogen storage bottle. Background technique [0002] Hydrogen storage alloys have a strong ability to capture hydrogen. Under certain temperature and pressure conditions, hydrogen molecules decompose into individual hydrogen atoms in the alloy. The reaction generates a large amount of metal hydrides and releases a large amount of heat; when the metal hydrides are heated, a decomposition reaction occurs, and hydrogen atoms can be combined into hydrogen molecules to be released and absorb heat at the same time. Utilizing this principle, hydrogen storage can be realized through hydrogen storage alloys. [0003] In the prior art, there is a method of using hydrogen storage cylinders for hydrogen compression storage, but when hydrogen storage alloys are used for hydrogen storage, hydrogen storage alloys with a weight of 1 / 3 of the hydrogen storage cyli...

Problems solved by technology

[0004] However, in actual application, the hydrogen storage technology using hydrogen storage alloys has not been well developed and applied because the cycle process of hydrogen storage absorption and release has not been well controlled.
