摘要
在国内外近十多年研究成果的基础上,综述气隙式膜蒸馏在传递方面的研究进展.主要阐述气隙式膜蒸馏过程的传热、传质机理,分析了温度、流速、气隙宽度、膜结构参数等因素对传质、传热过程的影响,对未来的研究提出了一些建议.
Reviewing the literatures about the investigations relevant the transfer mechanism in air gap rnembrane distillation in latest decade, the progress in studies on heat and mass transfer in the process was discussed. It mainly reviewed the effects of temperature, mass flow rate, air gap width, membrane parameters. Some ad- vices about research on transfer mechanism in air gap membrane distillation in future were given.
