槽式太阳能电站净化系统的研究

Research of the Ullage System in a Parabolic Trough CSP Plant

在槽式太阳能光热电站中,由于局部过热,导致导热油发生裂解,产生低沸点和高沸点杂质,为了除去杂质,电站设置净化系统,同时该系统也实现了电站系统泄压的目的。利用不同压力下各物质沸点不同的原理对杂质进行分离,保证了系统安全和系统的换热效率。

In a parabolic trough CSP plant,HTF may crack due to overheat and thus produce low-boiling and high-boiling impurities. In order to remove the impurities,ullage system,which separates the impurities under different pressures,is installed. It also serves as a pressure relief for the plant. Ullage system guarantees the safety and the heat transfer efficiency of the plant.
