Hydrogen-heat-electricity combined supply integrated system based on reactive metal hydrolysis hydrogen production

Abstract

The invention relates to a hydrogen-heat-electricity combined supply integrated system based on reactive metal hydrolysis hydrogen production. The hydrogen-heat-electricity combined supply integrated system comprises a steam generator, a steam heater, an adjustment control module, a reaction kettle, a steam turbine, a condensation tank, a drying tank, a hydrogen fuel cell, a hydrogen temporary storage module, a vacuum pump and a control station. The steam generator generates saturated steam, the steam heater performs secondary heating on the saturated steam to generate high-temperature superheated steam, the superheated steam reacts with the active metal in the reaction kettle to generate hydrogen, and hydrogen and steam mixed gas is condensed and dried to obtain hydrogen and steam mixed gas. High-purity hydrogen enters the hydrogen fuel cell at the tail end to achieve conversion from hydrogen energy to electric energy, and in the hydrogen preparation process, a large amount of heat released in the hydrogen preparation reaction process carried by a mixed gas of reaction products hydrogen and water vapor is recycled through a steam turbine, so that energy waste is reduced, and the energy utilization rate is increased. And the heat efficiency of the whole hydrogen-heat-electricity combined supply integrated system based on active metal hydrolysis hydrogen production is improved.
