Abstract

The invention aims to provide a factorial agricultural multi-stage solar energy and other energy complementary thermal power generation and poly-generation system which comprises solar energy acquisition systems and power generator units; a solar energy acquisition system and a solar power generator unit form a group of solar power generation systems; the solar power generation systems at least comprise two groups of solar power generation systems and at least one group of energy system which is provided by non-solar energy, so as to supply supplementary energy for the solar power generation systems; one group of solar power generation system can be serially/parallelly connected with the other group of solar power generation system; the waste heat after one group of power generation system generates power is utilized by the other group of power generation system, so that multi-stage waste heat utilizing power generation is realized; each of the two groups of solar power generation system can comprise a group of solar low-temperature power generation system and a group of solar high-temperature power generation system; and the waste heat of two stages of power generation systems can be utilized by the other stage, so that step acquisition and utilization are carried out on the solar systems with different acquisition temperatures.

Description

technical field [0001] The invention relates to complementary power generation of solar energy and other energy sources, especially a circular economy utilization system realized in combination with factory agriculture, that is, a power generation system and cogeneration system in which multi-level solar energy and other energy sources are complementary in factory agriculture, and the remaining heat can be used for Heating, cooling, drying, hot water and other applications in factory agriculture. Background technique [0002] Existing solar power generation mainly includes photovoltaic and photothermal power generation. Photovoltaic power generation requires silicon or other special materials for power generation. Photothermal power generation includes trough type, tower type and butterfly type. Thermal power is mainly large-scale power generation, and it is mainly a single-stage power generation system. Such a power generation system is mainly based on the traditional coal ...
