Heat insulation supporting structure of cryogenic high-pressure hydrogen storage bottle and cryogenic high-pressure hydrogen storage bottle

Abstract

The invention discloses a heat insulation supporting structure of a cryogenic high-pressure hydrogen storage bottle and the cryogenic high-pressure hydrogen storage bottle, and belongs to the field of cryogenic high-pressure hydrogen storage pressure containers. The heat insulation supporting structure of the cryogenic high-pressure hydrogen storage bottle comprises an outer tank positioning part, supporting pipes and an inner container positioning part. The supporting pipes are connected between the outer tank positioning part and the inner container positioning part. The heat insulation supporting structure is characterized in that the inner container positioning part comprises an annular positioning base, the annular positioning base is arranged on the outer surface of a sealing head of an inner container of the cryogenic high-pressure hydrogen storage bottle, the inner surface of the annular positioning base is a curved surface matched with the outer surface of the sealing head in shape, and the supporting pipes are arranged on the annular positioning base and distributed on the same circle. The heat insulation supporting structure has the advantages of being simple, convenient to manufacture and easy to assemble, and is particularly suitable for being used as a design scheme for a cryogenic high-pressure hydrogen storage bottle heat insulation supporting structure where welding spots cannot be arranged on the outer wall of the inner container.

Description

technical field [0001] The invention relates to the technical field of high-pressure containers, in particular to an insulating support structure of a cryogenic high-pressure hydrogen storage bottle and the hydrogen storage bottle. Background technique [0002] Hydrogen can be widely used in fuel cell power generation, nuclear fusion production capacity, direct combustion heat production and other fields. The current hot spot in the civilian field of hydrogen energy is fuel cell vehicles. However, the current domestic mainstream hydrogen transportation method is high-pressure gaseous transportation. This transportation method has low mass density and poor economic benefits. This method significantly increases the mass hydrogen storage density to 5.1%; and the cryogenic high-pressure hydrogen storage that is more suitable for medium and long-distance transportation innovatively combines the first two hydrogen energy transportation modes, so that hydrogen can be stored in a su...

Problems solved by technology

The difference from ordinary low-temperature containers is that the inner tank under great pressure needs to be wrapped with carbon fiber, while the heat-insulating support method adopted by ordinary low-temperature containers requires welding, drilling and other processing methods on the inner wall surface, which is no longer suitable for intolerant High temperature carbon fiber wrap
