Problems solved by technology

[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 of the working fluid in the gasification device is prone to incomplete gasification, the volume expansion is small, and the amount of external work in a single cycle of the gasification process is small; c. The gasification temperature is unstable, the condensation effect of the working medium is not good, and the working medium is easy to deteriorate or appear impurities; d. The driving force of the turbine is small, and the efficiency of converting the external work of the gasification medium into mechanical energy is low; e. The speed of the turbine is unstable, and It is prone to stuck problems; f. The heat collection effect of the heat collection device is not good, and the external waste heat absorption rate is small; g. The heat displacement of the condensing device is large, and the heat energy is wasted. The condensation speed through natural condensation is slow, and the use of Active condensation mode (fan air cooling or liquid pump water cooling) requires additional power consumption
[0008] Biological fermentation is widely used in the production of chemical raw materials and biomedicine. The biological fermentation process will generate a lot of heat, and the temperature of the fermentation heap can be as high as 70-75°C. During the production process, in order to prevent the temperature of the fermentation heap from being too high, regular Agitation for heat dissipation; this heat dissipation method fails to utilize the fermentation heat energy, and there is a waste of energy. At the same time, the mixer needs to be run during the heat dissipation process, which consumes a lot of energy
