Abstract

The invention discloses a solar energy, wind energy and fuel gas complementary combined hydrogen production methane production circulating heat power generation device. The device fully utilizes renewable energy such as solar energy and wind energy and a semi-closed supercritical carbon dioxide fuel gas Brayton thermal power generation system to realize complementary cycle power generation, the electric power generated by the solar energy and wind energy is mainly used for carrying out electrolysis hydrogen production and oxygen production on water generated by power generation of the system,the effluent carbon dioxide is subjected to hydrogenation methane preparation, oxygen is used for supporting combustion of natural gas or self-produced methane gas by the semi-closed supercritical carbon dioxide fuel gas Brayton thermal power generation system, and the high-temperature gas and the supercritical carbon dioxide power working medium which are fully mixed jointly drive a turbine to perform power generation; the water discharged by the system condensation and methanation preparation is collected not only for electrolytic hydrogen production, but redundant water is used for cleaninga solar energy mirror field or photovoltaic panels. According to the circulating thermal power generation device, the circulating thermal power generation is realized by means of renewable energy, and a technical basis is laid for replacing fossil energy power generation. The circulating thermal power generation device belongs to the technical field of solar energy thermal power generation and high-temperature thermal chemical interdisciplines.
