盐田太阳池实验研究

Study of salt-pan solar pond

在海边盐田建造了50m2的太阳池,以制盐的废弃液"老卤"灌注太阳池底层,以海水或收集的淡水冲洗水面,进行了太阳池蓄热的实验,测量了太阳池的密度、温度和浊度的分布,对盐田太阳池的运行维护和经济性进行了分析研究.对盐田太阳池特有的问题,如老卤的澄清化处理和卤虫的杀灭进行了实验.研究表明盐田太阳池是一种成本低、用途广泛、适于大规模应用的太阳能集热和蓄热装置.

This paper presents an experiment of a 50 m2 solar pond built inside a salt pan in Dalian.In the solar pond bittern from saltwork was used for the first filling, and seawater or fresh water collected was used for surface water.The profiles of temperature, density and turbidity of the solar pond are measured.Methods for maintenance of salt concentration gradient and brine transparency are presented. Bittern clarification and water sterilization were carried out. The calculation shows that the coastal solar pond which utilizes seawater as salt and water source is more economical than the coalburning boiler to provide low grade heat.
