Background technique [0002] Energy is an important material basis for the survival and development of human society. Throughout the history of the development of human society, every major progress of human civilization is accompanied by the improvement and replacement of energy. The development and utilization of energy has greatly promoted the development of the world economy and human society. [0003] However, with the continuous development and consumption of energy, non-renewable energy such as oil, coal, natural gas and other non-renewable energy sources are gradually shrinking, and energy conservation and recycling are gradually being valued. The basic content of my country’s current energy strategy is: persisting in giving priority to conservation, based on domestic, dive...

[0007] However, the common problems of existing thermal power generation equipment are: a. The temperature requirements for high-temperature heat sources are high, generally above 200°C, and the thermal energy conversion efficiency is low. The thermal energy conversion efficiency is generally 15% to 35%. Under the heat source of ℃, the average thermal energy conversion efficiency is 18%; b. The gasification temperature of the working fluid is unstable, the condensation effect of the working fluid is not good, and the working fluid is easy to deteriorate or appear impurities; c. The driving force of the turbine is small, and the gasification medium The efficiency of converting external work into mechanical energy is low; d. Turbine speed is unstable and prone to stuck problems; e. The heat collection effect of the heat collection device is not good, and the absorption rate of external waste heat is small; f. The heat displacement of the condensing device It is large, wastes a lot of heat energy, and the condensation speed through natural condensation is slow, and the active condensation method (fan air cooling or liquid pump water cooling) requires additional power consumption; g. The existing equipment is large in size; f. The turbine is prone to leakage Working fluid problem

[0009] However, the development of nuclear power has also brought great concerns to people, because the construction and use of nuclear power plants will not only cause certain radioactive pollution to the environment, but also cause high-temperature pollution to nearby waters.

Nuclear power plants need a large amount of water to cool the reactor. A nuclear power plant consumes hundreds of tons of water per second. Cold sea water or river water is discharged back into the sea after heat exchange in the plant. The temperature of the water will rise by 20 to 30 degrees. After the drain is discharged, the temperature of the water within a radius of 1 km can rise as high as 5°C to 8°C. When the temperature of cold sea water or river water reaches 30°C in summer, after absorbing the heat exhausted by the nuclear power plant, the temperature can rise by about 40°C. , the general fish and seaweed organisms cannot survive, and it also brings a greater impact of high temperature on nearby residents

[0010] As for the thermal energy in the thermal drainage of the above-mentioned nuclear power plant, since the temperature difference between the thermal drainage and normal temperature water is only about 20°C, this temperature difference is difficult to be utilized by existing thermal power generation equipment
