【摘要】：优化化工分离技术、实现化工分离过程的节能减排,一直是化工分离过程研究的热门课题。近年来,微波场强化分离过程的研究非常活跃。本文阐述了微波对物质的作用机理以及微波加热较普通加热的优势与特点;系统介绍了微波场在萃取、精馏、干燥、脱附/吸附、蒸馏和反应精馏等分离过程的强化效果和应用进展,并分析总结了微波场在这些分离过程中的强化机理,分析表明将微波应用于化工分离过程具有加热速度快、产品质量高、耗能低和易于控制等特点;同时指出微波在分离过程特别是蒸馏/蒸发和反应精馏领域研究的欠缺,提出对于微波是否对蒸馏/蒸发或反应精馏过程具有强化作用还需要大量的实验验证和相应的理论支撑;最后本文对微波在分离领域的发展作了分析与展望。
[Abstract]:Optimizing chemical separation technology and realizing energy saving and emission reduction in chemical separation process has been a hot topic in chemical separation process research. In recent years, the study of microwave field enhanced separation process is very active. In this paper, the mechanism of microwave action on matter, the advantages and characteristics of microwave heating over ordinary heating are described, and the microwave field in extraction, distillation, drying, desorption / adsorption are systematically introduced. The enhancement effect and application progress of separation processes such as distillation and reactive distillation are analyzed and summarized. The strengthening mechanism of microwave field in these separation processes is analyzed and summarized. The results show that microwave application in chemical separation process has high heating speed and high product quality. The characteristics of low energy consumption and easy control are pointed out, and the lack of microwave research in separation process, especially in the field of distillation / evaporation and reactive distillation, is pointed out. It is suggested that the enhancement of microwave to distillation / evaporation or reactive distillation still needs a lot of experimental verification and corresponding theoretical support. Finally, the development of microwave in the field of separation is analyzed and prospected.
