摘要/Abstract

摘要： 由于环流反应器内存在定向循环，与鼓泡塔反应器相比，其混合性能大幅提升，已广泛应用于许多工业过程，如发酵、反应器结晶等工业过程，近年来成为国内外学者研究的热点。针对环流反应器内操作条件下的流动形态、流体力学（包括相含率分布、循环液速、混合时间以及离集指数等）及传质/传热特性，总结了其最新研究进展，分析了相含率尤其是固含率变化对反应器中关键参数如循环液速和化学反应速率的影响，展望了从机理上研究相互耦合的多相流动、传质/传热和化学反应规律，为进一步推动其工业应用提供参考。

Abstract: Compared to bubble columns, the mixing performance in an airlift loop reactor is significantly improved due to the presence of regular fluid flow, which has been widely applied in many chemical processes, such as fermentation and crystallization. Therefore, it has become a hot research topic in recent years. The flow regimes, hydrodynamic characteristics (including phase holdup, circulation velocity, mixing time and segregation index) and mass/heat transfer characteristics are reviewed in this paper. The influence of dispersed holdups, especially that of solid on the key parameters in the reactor, such as circulation liquid velocity and chemical reaction rates, is analyzed. In addition, a perspective is given on multi-disciplinary study of multiphase flow, mass/heat transfer and chemical reactions with mechanistic models in order to promote the industrial application.

Key words: airlift loop reactor, multiphase flow, mixing, mass transfer, heat transfer
