Title:
TOWER-TYPE SOLAR SUPERCRITICAL AIR HEAT ABSORBER
Document Type and Number:
WIPO Patent Application WO/2024/031804
Kind Code:
A1
Abstract:
Disclosed in the present invention is a tower-type solar supercritical air heat absorber, comprising a heat absorbing plate, a cylindrical jacket, inlet and outlet pipes, a phase change working medium, a heat exchange medium, etc. Sunlight is reflected on the heat absorbing plate by a heliostat field, and a heat absorbing coating covers the heat absorbing plate to strengthen the heat absorbing capacity of the surface. The heat absorbing plate absorbs heat of sunlight and transmits the heat to the phase change working medium located in the heat absorbing plate, the phase change working medium is subjected to phase change to release the heat, and the heat is transmitted, through the outer wall of the cylindrical jacket, to the heat exchange medium located in the cylindrical jacket. The inlet and outlet pipes comprise inlet pipes and outlet pipes, and the heat exchange medium flows into the cylindrical jacket through the inlet pipes and flows out of the cylindrical jacket through the outlet pipes. The structure of the heat absorber enables compressed air to be heated to a supercritical state, thereby greatly improving power generation efficiency.
