The invention discloses a photo-thermal
power generation system comprising a diagrid industrial structure. The
system comprises a photo-thermal
tower, a steam generator, a
steam turbine, a hot fused salt tank, a cold fused salt tank, a connecting pipeline and the like. A fused salt heat absorber is supported at the top of the photo-thermal
tower, is connected with cold and hot fused salt pipelines in a structure and is connected with the cold fused salt tank, the hot fused salt tank and the steam generator outside the structure, power generation is conducted through acting of the
steam turbine, and the photo-thermal
tower is provided with an air inlet and outlet layer which is connected with a surface radiator inside the structure, a heat return
system outside the structure, a circulating water pump and the like to form a
surface type indirect
air cooling system. In conclusion, a high-efficiency photo-thermal
power generation system is formed, the system has photo-thermal power generation and heat dissipation and indirect cooling functions, the problems that a traditional direct cooling system is large in
power consumption, and an indirect cooling system is large in occupied area, long in construction period, high in initial investment and the like are solved,
environmental protection performance and
corrosion resistance of a project are improved, and anti-wind and anti-
seismic safety performance is excellent.
