多元盐除湿溶液的闪蒸再生机理研究进展综述

Survey on Flashing Regeneration Mechanism of Multielement Salt Desiccant Solution

多元盐除湿溶液的闪蒸再生问题一直成为溶液除湿空调发展的研究难点。文章详细阐述并讨论了传热传质理论、溶液再生方面与闪蒸方面的研究现状以及存在的问题。在此基础上,指出了今后要深入研究的方向:以现有的真空闪蒸理论为基础,建立符合其闪蒸特性的耦合传热传质模型和动力学模型,构建真空罐内闪蒸实验,从而推出其再生机理。

The flashing regeneration problems of multielement salt desiccant solution remain a serious threat on liquid des- iccant air- conditioning field. In this paper, heat and mass transfer theory, solution regeneration and flashing research stares, existing problems are described and discussed in detail. Based on this, some topics are for further investigations are pointed out： based on foregoing flashing in vacuum theory, a coupling heat and mass transfer and dynamics model are setting up, the flashing experiment in vacuum is conducting, finally we can obtain the regeneration mechanism.
