System for preventing solid hydrogen storage container from being in vacuum state

Abstract

The invention provides a system for preventing a solid hydrogen storage container from being in a vacuum state. The system specifically comprises an argon or nitrogen source, a regulating valve, a pressure detection device, a hydrogen storage container, a human-computer interface unit, a central control system and an audible and visual alarm. Two ends of the regulating valve are respectively connected with the argon or nitrogen source and the hydrogen storage container, the pressure detection device is also arranged between the regulating valve and the hydrogen storage container, the human-computer interface unit is connected with the central control system, and the central control system can realize a control function on the regulating valve and the audible and visual alarm. The system has the beneficial effects that the system for preventing the container from reaching the vacuum state to damage internal materials is provided for the magnesium-based hydrogen storage material test, no additional burden is added to the magnesium-based hydrogen storage material test, effective automatic treatment can be performed when manual operation fails, negative pressure can be prevented from being generated at the moment of negative pressure, the hydrogen storage container is prevented from absorbing external air after being in a negative pressure environment, and then the internal materials of the hydrogen storage container are prevented from being damaged.

Description

Technical field [0001] The present invention relates to the field of hydrogen storage, and more particularly to a system of solid-state hydrogen storage containers. Background technique [0002] Hydrogen can be clean and non-polluting new energy, but hydrogen is small in normal volume, low liquefied temperature, difficult to store and transport, which limits the promotion and application of hydrogen energy. Magnesium-based storage materials are a highly developing solid hydrogen storage material having high hydrogen storage capacity (7.6 wt.%), Extensive source, non-toxic, low cost, good safety, suitable for hydrogen Storage and transportation. The principle of the hydrogen storage material of the magnesium based storage material is to react with hydrogen hydrogen hydrogen-dehydrogenation at a certain temperature and hydrogen pressure conditions, thereby achieving the storage and release of hydrogen. When the temperature in the container rises to a certain extent, the container w...

Problems solved by technology

When the temperature in the container rises to a certain level, the container will absorb hydrogen back. If there is no external hydrogen to supplement, the container will form a vacuum state. The external air is easily sucked into the container in a vacuum state, and the material inside the container reacts and damages the material, so there is an urgent need to develop methods to prevent the container from reaching a vacuum state that absorbs outside air and damages its internal materials
