一种新型太阳能海水淡化系统的实验研究

介绍了一种新型的太阳能海水淡化方法,即结合太阳能空气集热器和太阳能热管、利用空气增湿除湿来实现海水淡化。分别进行了电吹风模拟太阳能空气集热器的蒸发器实验,以及结合3m2太阳能空气集热器和热管集热器的实际装置实验。结果表明,影响蒸发量的主要因素为热空气温度、热空气流量、初始水量、水温、出气孔直径和数量。实验结果表明,装置可获得的最大冷凝量为790g/h,计算出系统的产水率和热力学效率分别为5.59×10-5kg/kJ和12.4%。

Experimental Study on a New Type of Solar Desalination System

A new type of solar desalination system is presented,where both solar air collector and solar heat pipe are used to drive the air humidification/dehumidification process,to realize the desalination.The evaporator experiment was carried out by using an electric breeze to simulate the solar air collector.The results indicate that the most important parameters affecting the water evaporation rate are:the temperatures of water and hot air,the air flow rate,the initial water volume,the vent diameter and quantity...
