The invention discloses a circulating heat pump power generation system. The system comprises a first circulating circuit and a second circulating circuit, wherein the first circulating circuit comprises a heat accumulator, a compressor, a total heat exchanger, a storage tank, an expansion valve and a second evaporator; and the second circulating circuit comprises a generator, a steam turbine, a water heat exchanger, a cooling tower, a storage tank, a high pressure pump, a one-way valve, a first evaporator and a pressure storage tank, and the first evaporator and the pressure storage tank are located in the total heat exchanger. The circulating heat pump power generation system can utilize water heated by industrial waste heat, solar heat, geothermal energy and the like, so that dynamic pressure (steam pressure) produced by gas vaporization expansion of low-boiling point liquid in the evaporators achieves heat pump power generation through the effect that the generator is driven by an air motor or the steam turbine to operate.
Description
technical field [0001] The invention discloses a multi-cycle heat exchange power generation system, which belongs to the technical fields of waste heat recovery and green energy development and utilization. Background technique [0002] In the prior art, coal-fired or nuclear power generation is achieved by heating water to gasify and expand to generate dynamic pressure to drive a steam turbine to drive a generator to run. Heat pump technology in the field of heating and cooling has developed rapidly, but usually due to reasons such as low thermal efficiency, heat pump power generation systems often have low efficiency and low power generation efficiency. At the same time, due to the inevitable loss of energy conversion, conventional industrial waste heat (including waste heat gas, waste hot water) utilization systems will experience energy consumption losses in different components during use, especially in key components such as cooling towers, heat exchangers and other co...
