Abstract

The embodiment of the invention provides a low-temperature working substance power generation system and a power system, belongs to the technical field of the heat engine power generation, and particularly relates to a low-temperature power generation system with high efficiency by using a low-grade heat source, which are mainly applied to the fields of the ultra-low temperature waste heat power generation, the hot water power generation, water coolers and the like. The ORC Rankine cycle uses a working substance with a boiling point of 15 DEG C and can realize hot water power generation with the temperature of more than 60 DEG C-80 DEG C. The system uses carbon dioxide with a lower boiling point, even liquid air or liquid nitrogen, and the boiling point of the power generation working substance is as low as minus 196 DEG C, which can realize the hot water power generation with the temperature of more than 15 DEG C-20 DEG C. The core of the embodiment of the low-temperature working substance power generation system and the power system is to solve the problem of the condensation of a low-temperature power generation working substance, meanwhile, the problem of evaporation reductionof a low-temperature liquid working substance, and the problem of the shaft end leakage of a low-temperature working substance steam turbine or an expansion machine. The embodiment of the invention forms a set of complete and efficient low-temperature power generation system and power system for generating power by using low-grade energy which have the advantages of low temperature, low construction cost and high efficiency.

Description

technical field [0001] The present invention relates to the technical fields of low-temperature waste heat power generation, hot water power generation, chiller, etc., specifically, to a low-temperature power generation working medium with a standard boiling point lower than 0°C, which absorbs heat energy from low-grade heat sources and conducts high-temperature power generation. Power generation system and power system for efficient power generation. Background technique [0002] Most of the traditional power generation system and waste heat power generation system use water as the working medium for power generation. The water is pressurized and transported to the waste heat boiler through the water pump, absorbs high-grade waste heat and industrial waste heat, and is gasified to form high-pressure steam, which is then input and driven to the steam turbine. Rotate at high speed, or drive the generator to rotate at high speed to output electric energy. The exhaust steam di...
