Abstract

The invention discloses a solar photo-thermal power generation system and method based on a calcium-based thermochemistry energy storage system. The system comprises a calcination reactor, a carbon dioxide industrial turbine, a carbon dioxide compressor, a carbonation reactor and a carbon dioxide power generation turbine. An outlet of the calcination reactor communicates with an inlet of the carbon dioxide industrial turbine, an outlet of the carbon dioxide industrial turbine communicates with a gas inlet of the carbonation reactor, a gas outlet of the carbonation reactor communicates with aninlet of the carbon dioxide power generation turbine, an outlet of the carbon dioxide power generation turbine communicates with an inlet of the carbon dioxide compressor, and an outlet of the carbondioxide compressor communicates with a gas inlet of the carbonation reactor. The calcium-based thermochemistry energy storage system is combined with solar photo-thermal power generation, and the solar can be stably and continuously used.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to a solar thermal power generation system and method based on a calcium-based thermochemical energy storage system. Background technique [0002] Thermochemical energy storage is mainly based on a reversible thermochemical reaction, which stores and releases energy through the breaking and reorganization of chemical bonds. In the energy storage reaction, the energy storage material absorbs heat and decomposes into two substances for separate storage. When the two substances are fully contacted to react, the stored chemical energy is converted into heat energy and released. Thermochemical energy storage has high density and efficiency, and is suitable for high-temperature and high-density storage of solar thermal energy. The volume and weight energy storage density of thermochemical energy storage is much higher than that of sensible heat or phase change heat stora...
