Solid hydrogen storage container

Abstract

The invention discloses a solid hydrogen storage container which comprises a container body, end covers, a liquid inlet, a liquid outlet, a gas inlet and a gas outlet. A plurality of hydrogen storagepipes and cooling pipes communicating with the container body are arranged inside the container body. The hydrogen storage pipes are connected and communicated, and each hydrogen storage pipe and at least one cooling pipe are arranged adjacently. The end covers are arranged at the two opposite ends of the container body. The surfaces, towards the container body, of the end covers are provided withflow guiding channels not communicating with the hydrogen storage pipes. The multiple cooling pipes are connected through the flow guiding channels. The liquid inlet and the liquid outlet both communicate with the cooling pipes. The gas inlet and the gas outlet both communicate with the hydrogen storage pipes so as to achieve flowing of a cooling solution and conveying of hydrogen. The solid hydrogen storage container has the advantages that the number of components and the welding portions are greatly reduced, the production difficulty is lowered, the sealing performance is improved, the safety coefficient of the solid hydrogen container is improved, later maintenance and overhauling are convenient, and great assistance is brought to development of the solid hydrogen storage technology.

Description

technical field [0001] The invention relates to a technical solution in the field of hydrogen energy, in particular to a solid hydrogen storage container. Background technique [0002] Most of the existing solid-state hydrogen storage containers are made of steel pipe or steel plate to make a tubular shell, and then welded by end caps, joints and other components, and multiple hydrogen storage tanks need to be connected in parallel to increase the hydrogen storage capacity that meets the demand. [0003] And because the hydrogen storage material releases or absorbs a large amount of heat energy when absorbing and discharging hydrogen, the shell-and-tube solid hydrogen storage container of the existing structure needs to install a heat exchange liquid flow channel structure inside or directly pass through the outer surface of the tank as a heat transfer device. interface. [0004] However, this type of shell-and-tube container relies on welding to solve the sealing problem d...
