摘  要:基于喷淋水自循环与太阳能加热空气的方法,设计一种加湿除湿型海水淡化装置。首先对装置的结构及原理进行说明,然后对装置各部分的能量平衡进行分析,最后实验研究装置集热及产水性能。从实验结果可知,淡化装置所匹配的太阳能空气集热器效率在37%~50%之间,在循环风量为164.21 m^(3)/h、海水喷淋速率为971 kg/h以及淡水喷淋速率为896 kg/h的条件下,装置最大半小时产水量为2.2 kg。此外,研究结果显示,因喷淋水自循环,喷淋速率的变化对装置产水量的影响较小。A humidification-dehumidification desalination device is designed based on the method of self-circulated water spraying and solar air heating. Firstly,the construction and operation principle of the device are introduced. Then,the energy balance of each part of the device is analyzed. Finally,the heat collection and water production performance of the device are experimentally studied. The results show that the efficiency of the solar air collector matched with the desalination device is in 37%-50%. The maximum productivity reaches to 4.4 kg/h under the conditions of volume air flow rate of 164.21 m^(3)/h,seawater spraying rate of 971 kg/h and fresh water spraying rate of 896 kg/h. In addition,the variation of the spraying rate has little effect on the water yield due to the self-circulated water spraying.
