Quick-open type copper lining high-pressure hydrogen storage container

Abstract

The invention relates to hydrogen energy storage equipment, and aims to provide a quick-open type copper lining high-pressure hydrogen storage container. The container comprises a copper lining arranged in a hollow tubular outer cylinder, and the copper lining and the hollow tubular outer cylinder are in clearance fit. At least one end of the outer cylinder is provided with a quick-open sealing head, and the quick-open sealing head is cylindrical and is arranged in the outer cylinder in threaded connection and sleeved modes. A penetrating through hole is formed in the axial center of the quick-open sealing head, and the end part of the lining is arranged in the through hole in a sleeved manner. A connecting pipe end connector is fixed to the quick-open sealing head through an assembly composed of a flange and a bolt, the connecting pipe end connector is tubular, the middle of the connecting pipe end connector is provided with a radial boss used for positioning and transmitting loads, one side of the connecting pipe end connector extends into the end of the lining, and the other side of the connecting pipe end connector is used for being connected with an external hydrogen conveying pipe. According to the quick-open type copper lining high-pressure hydrogen storage container, the copper lining can effectively prevent high-pressure hydrogen from making contact with the outer cylinder, and performance degradation of the outer cylinder due to high-pressure hydrogen embrittlement is avoided. The strength of the outer cylinder cannot be limited, and lightweight design of the container is facilitated. By adoption of the quick-open sealing head, the outer cylinder does not need spinning formation, heat treatment can be facilitated, the hydrogen storage pressure of the container is high, and the volume is large.

Description

technical field [0001] The invention belongs to the field of hydrogen energy storage equipment development, in particular to a quick-open copper-lined high-pressure hydrogen storage container. Background technique [0002] Hydrogen storage is one of the core links in the hydrogen energy industry chain. High-pressure hydrogen storage is currently the mainstream hydrogen storage method for hydrogen fuel cell vehicles, long-tube trailers, and hydrogen refueling stations. High-pressure hydrogen storage containers are the carriers for high-pressure hydrogen storage. Different from conventional pressure vessels, hydrogen storage vessels may face degradation of material properties caused by high-pressure hydrogen embrittlement in a high-pressure hydrogen environment, which poses a great threat to the safe operation of the vessel. At present, the types of high-pressure hydrogen storage vessels mainly include large-volume seamless hydrogen storage vessels, austenitic stainless steel...
