Abstract

The invention discloses an internal circulation type solid particle air heat absorber for solar thermal power generation. A light inlet window (9) is formed in one side, which faces the projection of a condensation radiant energy flow (8), of a water absorber cavity (1). Solid particles (2) are positioned in the heat absorber cavity (1). An air inlet duct (3) is positioned in the heat absorber cavity (1). Open holes (4) are reserved in the wall surface of the air inlet duct (3). One end of the air inlet duct (3) is sealed, and the other end of the air inlet duct (3) is used as an air inlet (6) which is positioned in the bottom or the lateral surface or the top of the heat absorber cavity (1). An air outlet (10) is positioned in the top of the heat absorber cavity (1). Air under temperature of 700 to 1,300 DEG C and normal pressure or pressure of more than 1MPa can be obtained.

Description

technical field [0001] The invention relates to a tower type air heat absorber for solar thermal power generation. Background technique [0002] Economic development is inseparable from energy support. Energy issues and environmental issues are major issues that determine the prospects for human development in the 21st century. In recent years, my country has actively advocated the development and utilization of renewable new energy including wind energy and solar energy. Solar thermal power generation has the characteristics of cleanness, high efficiency, stability and reliability. With technological progress and improvement of the industrial system, its technical and economic advantages will be gradually improved. , has become an important way to utilize solar energy. [0003] Solar tower thermal power generation uses multiple heliostats that track the movement of the sun to reflect solar radiation to the heat absorber placed on the tower to obtain a high-temperature heat ...
