Solar energy heat energy multilevel power generation system

Abstract

The invention discloses a solar energy heat energy multilevel power generation system which is characterized by comprising a spotlighting tower and a heliostat field which is arranged at the left side of the spotlighting tower. A heat collector is arranged at the upper portion of the spotlighting tower. One end of the heat collector is connected with an oil storage tank with a cooling function. An input end of a temperature control module is connected with the heat collector. The temperature control module controls temperature of oil in the heat collector. The heat collector is connected with a first hot end of a first level thermoelectric generator. An outlet of the first hot end of the first level thermoelectric generator is communicated with an inlet of a second hot end of a second level thermoelectric generator. An outlet of the second hot end of the second level thermoelectric generator is communicated with the oil storage tank. An outlet of a first cold end of the first level thermoelectric generator is connected with an inlet of a third hot end of a third level thermoelectric generator. An outlet of a second cold end of the second level thermoelectric generator is connected with an inlet of a fourth hot end of a fourth level thermoelectric generator. The solar energy heat energy multilevel power generation system has the advantages of being efficient in use of solar energy heat energy, clean, energy-saving, simple and convenient to install, and capable of solving the problem that electricity is badly needed in areas without electricity or when power is blacked out.

Description

technical field [0001] The invention belongs to the technical field of solar thermal utilization, and in particular relates to a solar thermal energy multistage power generation system. Background technique [0002] Solar energy is the most abundant and most promising renewable energy in my country and the world, and it has been widely valued by countries all over the world because of its clean and pollution-free characteristics. Solar power generation technology is the most promising clean energy technology in the future, mainly including photovoltaic power generation and solar thermal power generation. [0003] Concentrating solar thermal power generation is a technology that converts solar radiation energy into thermal energy and then into electrical energy. As a low-cost clean energy technology with large-scale prospects, it is mainly divided into four forms: trough type, line type, and dish type. and tower. The tower solar thermal power generation system uses the heli...
