摘要：介绍了干湿壁温差推动膜蒸馏过程的基本原理,采用商业化的聚四氟乙烯疏水微孔平板膜搭建了配制海水的淡化实验装置,利用该装置分别探索了:一定相对湿度条件下,渗透通量与干球温度的变化规律;一定干球温度条件下,渗透通量与相对湿度的变化规律;一定湿球温度条件下,渗透通量与相对湿度的变化规律.试验表明:该装置能够有效地从环境中提取能源以推动膜蒸馏海水淡化过程的进行.
A fundamental principle of membrane distillation utilizing temperature difference between dry and wet wall was introduced. Commercial hydrophobic polytetrafluoroethylene （PTFE） microfiltration flat membrane module was used to set up a experimental device. The influences of dry wall temperature, wet wail temperature and relative humidity on permeate flux was studied using the device. Experiment results demonstrated that membrane distillation process for seawater desalination could effectively worked utilizing energy extracted from the environment.
