增湿去湿海水淡化技术的研究进展

Research progress of humidification-dehumidification desalination process

增湿去湿海水淡化技术是对主流海水淡化技术的一个重要补充。本文根据淡化装置中潜热利用方式、物料循环方式、淡化过程驱动形式、传热传质方式和能量供应对增湿去湿海水淡化装置进行了全面系统地分类,并从蒸发室、冷凝室和供能模块3个方面对增湿去湿淡化装置进行了详细的分析。总结归纳了表征增湿去湿海水淡化装置性能的主要指标,最后从装置材料、淡化工艺和结构设计等方面提出了增湿去湿海水淡化装置设计的思路与建议。

Humidification-dehumidification（HDH） desalination process serves as an important supplement to traditional desalination processes.In this work,HDH systems are classified according to the use of latent heat,material circulation,form of driving,heat and mass transfer methods and energy supply.Components of the HDH systems,such as humidifier,dehumidifier and energy supply module,were analyzed in detail.Performance indices of the HDH systems were summarized.Finally,design suggestions for HDH systems were proposed in terms of material,desalination technology,structural design,etc.
