Description

Technical Field

[0001] The present invention relates to the technical field of storage layers, and specifically to a storage layer structure for an organic liquid hydrogen storage tank. Background Art

[0002] A hydrogen storage tank is a device for storing hydrogen, usually made of carbon fiber composite materials. The hydrogen storage tank has the characteristics of high pressure resistance, corrosion resistance, light weight, high strength, etc., and can effectively improve the storage and use efficiency of hydrogen. In the hydrogen storage tank, hydrogen can be stored at a relatively low pressure and can be quickly released when needed. Therefore, it is widely used in the fields of energy storage, transportation, aerospace, etc. The main function of the storage layer of the hydrogen storage tank is to provide a storage space for hydrogen and ensure the safety and stability of hydrogen. It is usually designed as a multi-layer structure to provide better sealing performance and anti-leakage function. In the storage layer, hydrogen can exist in a liquid or gaseous state, but usually needs to be compressed or otherwise processed to be stored and transported.

[0003] The main hydrogen storage component inside the storage layer structure for the hydrogen storage tank is the hydrogen storage bed body element, which has excellent hydrogen absorption performance and long service life. It is a porous ceramic material, which is composed of metal oxides with main components such as Mg, Al, Ti, Zr, V, etc. mixed in a certain proportion. This material can absorb a large amount of hydrogen at room temperature and can maintain stable performance during repeated hydrogen charging and discharging processes. Currently, the hydrogen storage bed body element is usually in a fluffy honeycomb block structure. When in use, it can be filled into the hydrogen storage tank to absorb hydrogen for easy storage of hydrogen. Generally speaking, the hydrogen storage bed body element needs to be regularly inspected and maintained to ensure its safety and reliability. If the hydrogen storage bed body element is damaged or its performance deteriorates, it needs to be replaced in time. However, after the fluffy block-shaped hydrogen storage bed body element is repeatedly used for a long time, a large amount of debris is generated by extrusion, and it will be more troublesome to clean up these debris during replacement. Therefore, a storage layer structure for an organic liquid hydrogen storage tank is needed to solve the above problems. Summary of the Invention
