Embodiment Construction

[0041] Such as figure 1 and figure 2 As shown, an ultra-high pressure hydrogen storage container includes a double-layer cylinder, a cover arranged on both sides of the cylinder, and a self-tightening sealing assembly for connecting the double-layer cylinder and the covers at both ends. The inner layer of the cylinder is used to suppress the penetration of hydrogen atoms, and the outer cylinder 11 is used to ensure the strength of the cylinder. In the self-tightening sealing assembly, leakage holes are opened on the outer cylinder 11 of the double-layer cylinder.

[0042] The outer cylinder body 11 and the inner cylinder body 12 of the double-layer cylinder body are fitted together by shrink fitting. The inner cylinder body 12 is made of high-alloy stainless steel, and its main function is to effectively inhibit the penetration of hydrogen atoms. The outer cylinder body 11 is a high-strength steel material or an ultra-high-strength steel material, and is an integral forging...

Abstract

The invention relates to the technical field of hydrogen energy storage, in particular to an ultra-high pressure hydrogen storage container. The ultra-high pressure hydrogen storage container comprises a double-layer cylinder body, cover bodies arranged on the two sides of the cylinder body, and a self-tightening sealing assembly for connecting the double-layer cylinder body and the cover bodies at two ends, wherein the inner layer of the double-layer cylinder body is used for inhibiting the hydrogen atom penetration, and the outer cylinder body is used for ensuring the strength of the cylinder body, and a leakage hole is formed in the outer cylinder body of the double-layer cylinder body. The ultra-high pressure hydrogen storage container has the advantages that a double-layer structure is arranged, different effects are achieved by two layers, the leakage hole can release hydrogen under the condition of exceeding the set pressure to prevent the explosion of the container, and the safety performance of an ultra-high pressure hydrogen storage tank is greatly improved.

Description

technical field [0001] The invention relates to the technical field of hydrogen energy storage, in particular to an ultra-high pressure hydrogen storage container. Background technique [0002] The problem facing fossil energy is that it is restricted by the total amount of resources and environmental problems such as global warming. Hydrogen energy has the advantages of zero pollution, abundant resources, and high combustion value, and has become recognized as an ideal new energy source, and is even considered the ultimate solution to human energy problems. [0003] Hydrogen storage is a key problem that must be solved in the utilization of hydrogen energy. Because hydrogen is flammable, explosive, easy to leak, easy to cause hydrogen embrittlement of materials, light in weight and difficult to compress, etc., it brings great challenges to its safe and efficient storage. Although there are various hydrogen storage modes such as liquid hydrogen, material combination or ads...
