A solid-state hydrogen storage tank for magnesium-based hydrogen storage

Abstract

The invention discloses a solid-state hydrogen storage tank for magnesium-based hydrogen storage, comprising a tank body, a heat exchange box is fixed at the bottom of the tank body, a base is fixed at the bottom of the heat exchange box, and the heat exchange box A heat exchange mechanism is arranged inside, a walking mechanism is arranged at the bottom of the base, a pressure relief box is fixed on the side wall of the tank body, and a plurality of hydrogen absorption pipes are fixed through the side wall of the tank body. The sidewalls of the hydrogen pipes are inserted with gas supplementation pipes, and each of the hydrogen absorption pipes is provided with a propulsion temperature control mechanism. The advantage is: by setting up multiple hydrogen absorption pipes, the volume accompanying the hydrogen absorption process will increase, which will squeeze the slider to push the pressure rod to move to give way, so that the pressure generated during the volume change process can be controlled, and the hydrogen absorption pipe The effective distribution of , so that the actual pressure can be evenly distributed, so as to effectively avoid the uneven force on the tank, and avoid the stress concentration of the hydrogen absorbing material during the hydrogen absorption expansion process, which can cause damage to the tank.

Description

technical field [0001] The invention relates to the technical field of hydrogen storage, in particular to a solid-state hydrogen storage tank for magnesium-based hydrogen storage. Background technique [0002] As a clean and efficient secondary energy, hydrogen energy has been highly valued and extensively researched. There are mainly three practical hydrogen storage methods: high-pressure gaseous hydrogen storage, low-temperature liquid hydrogen storage tanks, and solid-state hydrogen storage based on hydrogen storage materials; [0003] Solid-state hydrogen storage technology uses the reaction of hydrogen and hydrogen storage materials to achieve hydrogen storage. Compared with other hydrogen storage methods, solid-state hydrogen storage technology has the advantages of high hydrogen storage density, low pressure, good safety, and high hydrogen purity. An important direction of the development of hydrogen storage technology, because the solid-state hydrogen storage form is...
