A kind of thermal insulation support structure of cryogenic high pressure hydrogen storage bottle and cryogenic high pressure hydrogen storage bottle

Abstract

The invention discloses an adiabatic support structure of a cryogenic high pressure hydrogen storage bottle and a cryogenic high pressure hydrogen storage bottle, belonging to the field of cryogenic high pressure hydrogen storage pressure vessels. The present invention is an adiabatic support structure for a cryogenic high-pressure hydrogen storage bottle, comprising an outer tank positioning part, a support pipe and an inner tank positioning part; the support pipe is connected between the outer tank positioning part and the inner tank positioning part, and is characterized in that: The inner tank positioning component includes an annular positioning base, which is arranged on the outer surface of the head of the inner tank of the cryogenic high-pressure hydrogen storage bottle, and the inner surface of the annular positioning base is in the same shape as the outer surface of the head. The supporting tubes are arranged on the annular positioning base and distributed on the same circle. The invention has the characteristics of simple structure, convenient manufacture and simple assembly, and is especially suitable for the design scheme of the thermal insulation support structure of the cryogenic high-pressure hydrogen storage bottle which cannot arrange welding points on the outer wall of the inner tank.

Description

technical field [0001] The invention relates to the technical field of high-pressure containers, in particular to an insulating support structure for a cryogenic high-pressure hydrogen storage bottle and a 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 mainstream hydrogen transportation method in China is high-pressure gaseous transportation, which 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, which is more suitable for medium and long-distance transportation, innovatively combines the first two hydrogen energy transportation modes, so that hydrogen energy can be stored in a low temperatur...

AI Technical Summary

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
