Abstract

The invention relates to a solar thermal power generation method and device. The method adopts an operation mode of overlapping top Britten circulation and bottom Britten circulation, and adopts air as a circulation working medium. After the air is pressurized by a top circulation air compressor, the air is fed into a cavity type receiver of a solar heat collecting device for absorbing heat; and the air, with higher temperature, discharged by a high-temperature air turbine in the top Britten circulation is used as a heat source of the bottom Britten circulation, thereby to forming an overlapped solar thermal power generation system. The device can effectively improve the solar thermal power generation efficiency, is excellent in unit safety and economy, and is specifically suitable for water-deficient areas.

Description

technical field

[0001] The invention relates to a solar thermal power generation method and device, specifically belonging to the technical field of solar thermal utilization. Background technique

[0002] With the vigorous development of renewable energy utilization in the world, concentrated solar power (CSP) and photovoltaic solar power (PV) have developed rapidly. The use of solar photovoltaic power generation can only make use of light with a shorter wavelength, and the light with a longer wavelength is completely wasted, and the temperature of the battery increases, resulting in a decrease in the efficiency of the battery, while the use of solar thermal power generation can make full use of the entire wavelength Therefore, concentrating solar power (CSP) is gradually recognized, researched and valued by people. Compared with photovoltaic solar power (PV), concentrating solar power (CSP) has outstanding features such as large scale, high concentration, and high efficie...
