The invention discloses a terrestrial heat, waste heat and photo-thermal coupling power generation system which comprises a power generation heat source and an ORC power generation system. A circulating heat exchange loop is formed between the ORC power generation system and the power generation heat source; heat exchange is carried out between an internal circulation working medium of the power generation heat source and an internal circulation working medium of the ORC power generation system through the circulating heat exchange loop; an ORC power generation device in the ORC power generation system generates power through the exchanged heat; the ORC power generation device comprises an evaporator and a preheater; the evaporator and the preheater are connected in series; and the evaporator and the preheater are positioned on the circulating heat exchange loop. The terrestrial heat, waste heat and photo-thermal coupling power generation system provided by the invention can effectively achieve the effect of full and sustainable utilization of medium and low temperature photo-thermal, terrestrial heat and waste heat resources.
Description
technical field [0001] The invention relates to the field of coupled power generation of geothermal and waste heat with light and heat. Background technique [0002] The organic Rankine cycle power generation device utilizes the low boiling point characteristics of organic working fluids (such as R134a, R245fa, etc.), and can obtain higher vapor pressure under low temperature conditions (80-300°C), push the expander to do work, and drive the generator to generate electricity, thereby Realize the conversion of low-grade thermal energy to high-grade electric energy; solar energy is greatly affected by climate, day and night, and the generator electrode is not constant. Therefore, an energy storage device must be equipped, which not only increases technical difficulties, but also increases the cost. Although a variety of battery energy storage systems have been manufactured, the cost is high and the disposal of the batteries brings environmental pollution. Through the couplin...
