中文摘要：
按气、液两相在多孔介质中不同的流动与接触方式,将应用于蒸馏过程强化的多孔介质传质元件分为三大类进行了系统的介绍,即气/液两相均在多孔介质内部流动的气液逆流接触方式、气相在多孔介质内部流动/液相在多孔介质表面流动的气液错流接触方式以及液相在多孔介质内部流动/气相在多孔介质表面流动的气液逆流接触方式。详细阐述了本课题组对各类多孔介质传质元件的研究思路与历程,总结其流体力学和传质性能与相应传统传质元件相比的优缺点,进而指出了多孔介质泡沫材料强化传质过程的作用机理是其能在蒸馏过程中得以多元化应用所亟待解决的关键科学问题。
英文摘要：
The mass transfer elements of porous media used in distillation process intensification are systematically reviewed in three major categories according to different contact styles of gas-liquid two phase in porous media： gas/liquid phases counter-current contact in porous media, gas flow in porous media/liquid flow on the surface of porous media cross-current contact and liquid flow in porous media/gas flow on the surface of porous media counter-current contact. The experiences and ideas of our research group on the study of various porous media mass transfer elements are expatiated. The comparison of hydrodynamic and mass transfer performance between the mass transfer elements of porous media and conventional mass transfer is conducted, and then the mechanism of mass transfer intensified by porous media foam materials is proposed as the key science problems of the diversified applications in the distillation process.
