盐梯度太阳池的建立及运行实验研究

Study of establishment and operation of salt-gradient solar pond

文章主要以不同浓度的卤水为工质建立了一个室外小型太阳池,并开展了太阳池的稳定运行及蓄热试验研究。研究结果表明,在太阳池的稳定运行中,非对流区的浓度梯度必须保持相对稳定,浓度梯度的变化将对太阳池的吸热和储热产生较大的影响。另外,下对流层的厚度增加有利于太阳池盐梯度的保持。

In this paper,it was presented that the establishment and experimental investigation of a salt-gradient solar pond. The solar pond was filled with salty water to form three zones（ e. g.,upper convective zone,non-convective zone and lower convective zone） accordingly with different methods of saline injection. Parameters like salinity and temperature were measured and recorded daily at various locations in the salt-gradient solar pond. The results showed that solar pond collected and stored solar energy for a long period of time can be possible by controlling the thickness and salinity of salt gradient layer of the solar pond. Otherwise,the increase depth of the LCZ was benefit to maintain the salt gradient of the solar pond.
