多塔式二元工质太阳能高温热发电系统技术方案

多塔式二元工质太阳能高温热发电系统，包括水工质吸热器、汽包、熔盐吸热器、给水泵、饱和蓄热器、熔盐泵、熔盐罐、蒸汽过热器、辅助加热器、除氧器、汽轮机、凝汽器、凝结水泵组成；汽包内的水通过自然循环的方式进入水工质吸热器内，完成水的预热蒸发过程；经汽水分离后，饱和蒸汽被引入饱和蓄热器；在熔盐吸热器内，熔盐被加热，然后在蒸汽过热器中释放热量，把饱和蒸汽加热成需要的过热蒸汽参数，最后通过蒸汽导管引至汽轮机做功；膨胀做功后的蒸汽在凝汽器中冷凝变成凝结水，被凝结水泵输送至蒸汽式除氧器，除氧后的水再通过给水泵送入吸热器上面的汽包，完成一个循环过程。本发明专利技术在提高太阳能热发电系统效率的同时，还具有安全性高、投资省、运行维护简单等特点。

Multi tower two element working solar high temperature thermal power generation system

Multi tower two yuan medium high temperature solar thermal power generation system, including water heater, steam drum, molten salt receiver, water pump, accumulator, saturated salt pump, molten salt tank, steam superheater, auxiliary heater, deaerator, steam turbine, condenser, condensate pump water into the drum; water heater through natural circulation, preheating water evaporation process completed by steam; after the separation of saturated steam is introduced into saturated accumulator; in the molten salt receiver, molten salt is heated, and then release the heat in the steam superheater, the saturated steam heating into superheated steam parameters. Finally through the steam conduit to the turbine output; expansion steam after the condenser is condensed into condensed water is conveyed to the steam condensate pump type deaerator deaerator after water through the water pump The drum that is fed to the absorber completes a cycle. The invention has the advantages of high safety, low investment, simple operation and maintenance, and the like, while improving the efficiency of the solar thermal power generation system.
