Extinction Performance Research on the Functioned Water in the Concentrating Light and Direct-Heating Solar Desalination System

本文提出了一种定日镜塔式聚光直热太阳能海水淡化系统,对系统中海水进行了功能化,并在暗室中对水体的消光性能进行了实验研究,分析了功能化水体深度、功能粒子丰度、水体沸腾程度等对水体通光率和消光率的影响,对有、无功能粒子的水体通光率随沸腾程度变化曲线进行了函数拟合。结果表明,在海水中添加功能粒子可以实现对海水的功能化,功能化水体的消光性能随功能粒子丰度、水体沸腾程度的增大而得到强化,功能化水体通光率与沸腾程度呈指数函数变化趋势。

A novel concentrating light and direct heating type solar desalination system and working principle were presented,and the seawater in the system was functioned.Experimental study from the view point of optics was performed to investigate the extinction performance of the functioned water in the system.The effect of experimental water depth,functioned particle abundance and water boiling extent on the transparency rate and extinction rate was analyzed.The variation of the transparency rate of the water with functioned particle and without functioned particle with the water boiling extent was function fitted.The experimental results indicated that functioned water through adding functioned particle in seawater can be achieved,and the transparency performance of the functioned seawater strengthens with increasing functioned particle abundance and water boiling extent.The transparency rate of functioned seawater attenuated exponentially with the water boiling extent.
