Supercritical solar power station adopting liquid-state lead and bismuth for heat transferring and heat storage

The invention provides a supercritical solar power station adopting liquid-state lead and bismuth for heat transferring and heat storage. The supercritical solar power station adopting liquid-state lead and bismuth for heat transferring and heat storage comprises a liquid-state lead and bismuth heat transferring and heat storage system composed of a light condensation and heat collecting device, a hot section storage tank, a hot section lead and bismuth pump, a cold section storage tank, a cold section lead and bismuth pump and a steam generator, and a steam power generation system composed of the steam generator, a turboset, a power generator, a condenser and a water feeding pump. According to the liquid-state lead and bismuth heat transferring and heat storage system, liquid-state lead and bismuth flow into the light condensation and heat collecting device from the cold section storage tank, flow into the hot section storage tank after being heated, and then enter the steam generator to heat a work medium, and meanwhile residual heat energy is stored in the hot section storage tank. According to the steam power generation system, supercritical steam is generated in the steam generator to push the turboset to work so that heat energy can be converted into kinetic energy, and then the kinetic energy is converted into electric energy through the power generator. The liquid-state lead and bismuth are used as the heat transferring and heat storage medium, the design of the heat transferring and heat storage system is simplified, and the reliability of the system and the total thermoelectric efficiency of the power station are improved.
