Abstract

The invention relates to a heat engine-hydrogen reaction bed combined circulating system comprising a heat engine, a hydrogen compression unit, an intermediate reheater and an expansion machine. The hydrogen compression unit is provided with at least one set of hydrogen reaction beds, each set comprises the at least two hydrogen reaction beds, and the hydrogen reaction beds mutually communicate. The expansion machine adopts multiple stages, and a thermal medium outlet of the heat engine is connected to a tail gas discharging opening through the hydrogen reaction beds and the intermediate reheater. The hydrogen reaction beds of the hydrogen compression unit are connected to an inlet of the expansion machine, a first-stage outlet and / or a second-stage outlet of the expansion machine are / is connected with the intermediate reheater or the hydrogen compression unit, an outlet of the intermediate reheater or the hydrogen compression unit is connected with a next-stage inlet of the expansionmachine, and the outlets of the expansion machine are connected to the hydrogen reaction beds of the hydrogen compression unit. The heat engine and the hydrogen reaction beds of the hydrogen compression unit are combined, tail gas waste heat after the heat engine does work is fully utilized to heat metal hydride, high-pressure hydrogen is generated to promote the expansion machine to do work, andthus the thermal efficiency is advantageously improved.

Description

technical field [0001] The invention belongs to the technical field of hydrogen energy power equipment, and relates to hydrogen power cycle utilization equipment, in particular to a heat engine-hydrogen reaction bed combined cycle system. Background technique [0002] In the 21st century, the automobile engine industry has developed rapidly, but gasoline engines and diesel engines are still the main types of automobile engines. Both gasoline and diesel are non-renewable resources. In order to alleviate a series of negative effects brought about by the scarcity of petroleum resources, as well as reduce air pollution and vehicle engine exhaust emissions, it is necessary to find alternative fuels for engines, and hydrogen energy is currently the most ideal clean fuel. The new energy economy that replaces the fossil energy economy, or the new energy economy in the post-petroleum era will be "hydrogen energy economy", "low-carbon economy" and its diversification of nuclear energ...
