A hydrogen charging system for a magnesium-based solid hydrogen storage reactor

Abstract

This utility model discloses a hydrogen charging system for a magnesium-based solid hydrogen storage reactor. Hydrogen storage tanks are placed in various positions within the reactor's inner cavity, and heat exchange coils are installed outside these positions. The hydrogen charging system includes a hydrogen charging section, a temperature control section, and a safety protection section. The hydrogen charging section includes a main hydrogen charging pipeline, on which a hydrogen flow controller and a hydrogen heat exchanger are installed. The temperature control section includes an external heat transfer oil circulation system, which includes a heat transfer oil tank. A flow bypass pipeline is provided between the inlet and return oil pipelines, and an automatic heat transfer oil diversion valve is installed on the flow bypass pipeline. The safety protection section includes a safety valve installed on the reactor, connected to a vent pipeline. A pressure relief bypass pipeline is provided between the vent pipeline and the main hydrogen charging pipeline, and an automatic pressure relief valve is installed on the pressure relief bypass pipeline. The advantages of this utility model are: it enables rapid and efficient hydrogen charging of multiple hydrogen storage tanks within the reactor, ensuring the safety of the system.
