Abstract

The invention relates to a metal hydride hydrogen energy work-doing system comprising a protective cover, a B1 metal hydrogen storage material reaction bed, a B2 metal hydrogen storage material reaction bed, a heat exchanger, a water cooler, a hydrogen expansion machine and a liquid hydrogen high-pressure pump, wherein the B1 metal hydrogen storage material reaction bed, the B2 metal hydrogen storage material reaction bed, the heat exchanger, the water cooler, the hydrogen expansion machine and the liquid hydrogen high-pressure pump are arranged in the protective cover. The B1 metal hydrogen storage material reaction bed and the B2 metal hydrogen storage material reaction bed are connected with the hydrogen expansion machine through the shell pass of the water cooler, and materials returnto the B1 metal hydrogen storage material reaction bed and the B2 metal hydrogen storage material reaction bed through a tube pass of the heat exchanger. The metal hydride hydrogen energy work-doing system utilizes the hydrogen absorption / hydrogen desorption features of the metal hydrides to drive the expansion machine to do work.

Description

technical field [0001] The invention belongs to the technical field of energy comprehensive utilization, and relates to a metal hydride hydrogen energy work system. Background technique [0002] Energy shortage, environmental pollution, and global climate change make it urgent to develop clean, efficient, safe and sustainable energy, among which hydrogen energy is being valued by more and more countries. In the 21st century, the engine industry has developed rapidly, but gasoline engines and diesel engines are still the main choices of engines. Gasoline and diesel are non-renewable resources. In order to alleviate a series of negative effects brought about by the shortage of petroleum resources, as well as reduce air pollution and engine exhaust emissions, it is necessary to find alternative fuels for engines, and hydrogen energy is currently the most ideal clean fuel. . With the increasingly stringent environmental protection measures around the world, hydrogen energy eng...
