Abstract

The invention relates to a metal hydride low-temperature cycle work and oxygen generation system. The metal hydride low-temperature cycle work system comprises a protective cover, a B1 metal hydrogenstorage material reaction bed, a B2 metal hydrogen storage material reaction bed, a hydrogen heat exchanger, a heat exchanger, an air heat exchanger, a hydrogen expander 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 hydrogen heat exchanger, the heat exchanger, the air heat exchanger, the hydrogen expander 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 separately connected with the hydrogen expander through the shell passes of the hydrogen heat exchanger and the air heat exchanger, and then return to the B1 metal hydrogen storage material reaction bed and the B2 metal hydrogen storage material reaction bed through the tube passes of the hydrogen heat exchanger and the heat exchanger. According to the system, the expander is drivento do work by utilizing the hydrogen absorption / hydrogen desorption characteristics of the metal hydride.

Description

technical field [0001] The invention belongs to the technical field of energy comprehensive utilization, and relates to a metal hydride low-temperature cycle work and oxygen production 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 th...
