Hydrogen heat exchange medium bimetal hydride work system

Abstract

The invention relates to a hydrogen heat exchange medium bimetal hydride work system. The system comprises a metal hydrogen storage reaction bed A1, a metal hydrogen storage reaction bed A2, a metal hydrogen storage reaction bed B1, a metal hydrogen storage reaction bed B2 and a generator. And hydrogen discharge outlets of the metal hydrogen storage reaction bed A1 and the metal hydrogen storage reaction bed A2 are connected to hydrogen absorption inlets of the metal hydrogen storage reaction bed B1 and the metal hydrogen storage reaction bed B2 through a hydrogen heat exchanger A and a high-pressure expansion machine. And hydrogen discharge outlets of the metal hydrogen storage reaction bed B1 and the metal hydrogen storage reaction bed B2 are connected to hydrogen absorption inlets of the metal hydrogen storage reaction bed A1 and the metal hydrogen storage reaction bed A2 through a liquid hydrogen precooler, a liquid hydrogen high-pressure pump, a refrigeration unit and a B hydrogenheat exchanger via a low-pressure expansion machine. And another outlet of the low-pressure expansion machine is connected to hydrogen absorption inlets of the metal hydrogen storage reaction bed B1and the metal hydrogen storage reaction bed B2. The reversible compression / expansion machine acts to drive work equipment to work or drive power generation equipment to generate power, thus fully utilizing industrial waste heat and natural energy.

Description

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

Problems solved by technology

Traditional hydrogen energy utilization mostly obtains thermal energy and kinetic energy by directly burning gaseous hydrogen, but gaseous hydrogen is not easy to store and transport, and the hydrogen energy obtained from combustion is directly used in the power system, which will cause a series of problems that affect safe use, such as knocking and instability.
