Problems solved by technology

[0003] The current solar power generation system has its own advantages and disadvantages, for example: the conversion efficiency of photovoltaic power generation is too low, and the pollution in the manufacturing process is serious, and the unit power generation cost is relatively high; the current solar Stirling technology is not very mature, and the Stirling engine needs to focus on The sunlight reaches a very high temperature (700°) to operate, and the photoelectric conversion efficiency is not very high; the conversion efficiency of the solar thermal molten salt heat storage power generation system is also very low, etc.
[0004] Now the solar Stirling power generation system has been paid more and more attention by people, and it has been developing faster and faster in recent years. The distribution of resource reserves matches; the second is the highest thermal efficiency; the third is its compact structure and easy installation, but the current peak power generation efficiency is 30%, and the heat loss of the original Stirling engine is 2 to 3 times that of the internal combustion engine. Therefore, since 1816 It has not been vigorously promoted since its invention

Abstract

The invention provides a solar steam thermoelectric system and belongs to the field of power generation equipment. The solar steam thermoelectric system comprises a solar energy collecting assembly, a high-pressure hot water boiler, a steam converting power device, a generator, a steam radiator and a high-temperature water pressing-back device. The high-pressure hot water boiler is located at the energy output end of the solar energy collecting assembly. The steam converting power device is provided with a high-pressure water steam input end, a power output end and a lower-pressure water steam output end. The high-pressure water steam input end is connected with the high-pressure hot water boiler. The generator is connected with the power output end. The steam radiator is connected with the lower-pressure water steam output end. High-pressure liquid water flows back into the high-pressure hot water boiler through the high-temperature water pressing-back device. According to the solar steam thermoelectric system provided by the invention, after high-pressure water steam does work, the steam radiator lowers the temperature of low-pressure steam to the critical point, low-temperature steam condenses into high-temperature hot water, high-temperature hot water flows back into the high-pressure hot water boiler, the internal energy of water steam can be fully used, and the efficiency of light energy conversion is further improved.
