Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0011] figure 1 Shown is the fluidized bed air heat absorber of the present invention. The heat absorber is composed of a heat absorber cavity 1, solid particles 2, a light-transmitting window 3, an air inlet 5, an air distribution plate 7, a baffle plate 8, and an air outlet 9. The heat absorber cavity 1 is cylindrical or square and made of high temperature resistant material. The air inlet 5 is located at the bottom of the heat absorber cavity 1, and its shape can be circular, square or other shapes, and its design principle is to ensure that the cold air 6 can enter the heat absorber cavity 1 smoothly. The air outlet 9 is located at the top of the heat absorber cavity 1, and the shape of the air outlet 9 can be circular, square or other shapes, and its design principle is to ensure that the hot air 10 can flow out of the heat absorber cavi...

Abstract

A fluidized bed air heat absorber used for solar thermal power generation comprises a heat absorber cavity (1), solid particles (2), a light-pervious window (3), an air inlet (5), an air distributing plate (7), a baffle (8) and an air outlet (10). The heat absorber cavity is barrel-shaped or square, the solid particles (2) are stored in the heat absorber cavity, the light-pervious window (9) is located on the side, facing shooting of light-collecting radiant energy flux (4), of the heat absorber cavity (1), the air inlet (5) is located in the bottom of the heat absorber cavity (1), the air distributing plate (7) is fixed to the inside of the heat absorber cavity (1) and above the air inlet (5), the baffle (8) is fixed to the inside of the heat absorber cavity (1), and the air outlet (10) is located in the top of the heat absorber cavity (1). All portions of the heat absorber except the light-pervious window are coated with high-temperature-resistant and heat-preserving layers.

Description

technical field [0001] The invention relates to a tower type air heat absorber for solar thermal power generation. Background technique [0002] Tower-type solar thermal power generation is to reflect solar radiation to the heat absorber placed on the tower through multiple heliostats that track the movement of the sun to obtain high-temperature heat transfer fluid. The high-temperature heat transfer fluid directly or indirectly passes through the power generation system of the thermal cycle. It mainly includes heliostat, heat absorber support tower, heat absorber, heat storage and generator set, etc. The heat absorber is the core device of the light-to-heat conversion of the tower system, and its performance directly affects the system efficiency. According to the difference of the heat transfer fluid in the heat absorber, the tower solar thermal power plants currently in operation and under development in the world mainly include water / steam, molten salt and air. The air...
