Hydrogen heat exchange medium monometal hydride acting system

Abstract

The invention relates to a hydrogen heat exchange medium monometal hydride acting system, and the system comprises a B1 metal hydrogen storage reaction bed, a B2 metal hydrogen storage reaction bed, ahydrogen expansion machine, an A air heat exchanger, an A hydrogen heat exchanger and a refrigerating unit. Hydrogen release outlets of the B1 metal hydrogen storage reaction bed and the B2 metal hydrogen storage reaction bed are connected to hydrogen absorption inlets of the B2 metal hydrogen storage reaction bed and the B1 metal hydrogen storage reaction bed through a hydrogen liquefier, a liquid hydrogen high-pressure pump, a refrigeration unit, an air heat exchanger A, a hydrogen heat exchanger A and a hydrogen expander; heat exchange outlets of the B1 metal hydrogen storage reaction bedand the B2 metal hydrogen storage reaction bed are connected to heat exchange inlets of the B1 metal hydrogen storage reaction bed and the B2 metal hydrogen storage reaction bed through a high-pressure hydrogen circulating pump and a heat exchange tube pass of the A hydrogen heat exchanger. The hydrogen absorption / desorption characteristics of the metal hydride are utilized, the expansion machineacts to drive acting equipment or a generator to generate electricity, natural energy and industrial waste heat are fully utilized, energy conservation and emission reduction are facilitated, and economic benefits are created.

Description

technical field [0001] The invention belongs to the technical field of energy comprehensive utilization, and relates to a hydrogen heat exchange medium single metal hydride 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...
