基于充分混合、均匀分布准则的化工过程强化:青岛科技大学的实践

过程强化是化学工程与技术领域的研究热点之一。掌握并利用单元操作或单元过程的共性本质、原理和相互影响规律，是实现化工过程强化的基本途径。在过去的二十多年里，青岛科技大学化学工程研究所基于对多相流动规律的认识，提出了“充分混合、均匀分布”的多相流调控准则并利用它进行化工过程强化研究。本文简述了“充分混合、均匀分布”准则的基本内容，详细介绍了在环流式旋风分离器、强放热流态化和精馏洗涤过程——几个在工业生产中得到成功应用的案例中，利用“充分混合、均匀分布”调控准则，实施过程强化的方式、方法以及强化效果，阐明了利用“充分混合、均匀分布”准则实现化工过程强化的可行性，及其在其中所起到的关键作用和未来发展趋势。

Process intensification based on fully mixed and evenly distributed method:practice in Qingdao University of Science and Technology

Process intensification is one of the research hotspots in the field of chemical engineering and technology. By only to master the rule of common nature,principle and influence each other,it is possible to optimize the design of the chemical process,reasonable regulation of unit operations or unit process to achieve the chemical process intensification. Based on the understanding of the law of multiphase flow,Institute of Chemical Engineering,Qingdao University of Science and Technology has put out a rule of multiphase flow regulation,named "Fully Mixed,Evenly Distributed",and has been done a lot of research work related to the subject of process intensification in the past decades. This review introduced the main contents of "Fully Mixed,Evenly Distributed",and discussed the process intensification methods based on "Fully Mixed,Evenly Distributed" and its effect in some successful application cases,such as circumfluent cyclone separator,strong exothermic fluidized process and washing and distillation process. This review also clarified the feasibility of chemical process intensification using "Fully Mixed,Evenly Distributed" regulation,as well as its key role and trend of process intensification technology.
