The invention relates to a multi-
tower binary-working-medium solar high-temperature
heat power generation
system which comprises a water working-medium heat absorber, a
steam dome, a
molten salt heat absorber, a water feeding pump, a saturated heat accumulator, a
molten salt pump, a
molten salt tank, a steam overheater, an auxiliary heater, a
deaerator, a
steam turbine, a condenser and a
condensate pump; water in the
steam dome enters the water medium heat absorber in a natural circulation way to finish the preheating and evaporating process of water; after steam-water separation, saturated steam is introduced to the saturated heat accumulator; molten salt is heated in the molten salt heat absorber and is subjected to heat release in the steam overheater so that the saturated steam is heated to reach required overheat parameter parameters, and finally, the heated saturated steam is introduced to the
steam turbine to work; and the steam subjected to expansion working is condensed into
condensed water in the condenser, the
condensed water is conveyed to the steam-type
deaerator through the
condensate pump, and the deaerated water is conveyed to the
steam dome on the heat absorber through the water feeding pump, thereby a circulation process is finished. The multi-
tower binary-working-medium solar high-temperature
heat power generation
system has the characteristics of high safety, saved investment, simpleness in operation and maintenance, and the like at the same time of improving the efficiency of the
solar heat power generation system.
