本文设计了一种适用于太阳能膜蒸馏技术的新型层叠式空气隙膜蒸馏组件,该组件结构紧凑,可由冷、热、冷等N层容腔并联运行,膜组件中的分水盘使热溶液调整为沿着膜面切向方向的旋转入流,在贴近膜面处形成漩涡流动,从而破坏了膜面附近的温度和浓度极化,提高了膜通量。以自来水为热工质,实验研究了温度和流量对膜通量的影响,该组件温度70℃,流量300L/h其产水通量达到最大；如并联10个热容腔,每昼夜(10h)产水为120kg,可以解决一家人的正常用水。以太阳能作为组件的加热热源,分析了3m2集热系统在自然循环状态下,集热器出口温度、水箱温度和太阳辐射对膜通量的影响,为应用太阳能膜蒸馏解决西部地区苦咸水淡化问题奠定了实验基础。
