摘要： 超重力旋转床作为如今非常重要的过程强化设备,已被广泛应用于各种化工单元操作过程之中。超重力旋转床内部的转子作为最核心的元件,其结构已发展出很多种不同的形式。本文按照转子形式的不同将超重力旋转床分为两大类,即一体化转子旋转床和分区转子旋转床,据此详细总结并介绍了各种具有典型意义的超重力旋转床的基本结构和研究近况。通过对流体动力学、传质和能耗三方面指标的讨论与分析,指出了各种类型超重力旋转床性能上的优势和存在的缺陷,对不同分离过程的结构选型具有一定的指导意义,为未来超重力旋转床转子的结构设计与优化提供了更加广阔的思路。最后,指出了现有超重力旋转床在机械方面研究的不足以及未来从基本原理的角度出发对转子进行结构设计与优化的必要性。

Abstract: Higee rotating bed is important in process intensification and has been widely used in various unit operations. As its key component, various forms of rotor structure has been developed. The rotating bed can be classified into two categories according to rotor structure:the rotating bed with block rotor and the rotating bed with partition rotor. The elementary structures and recent researches of all typical types of rotating bed are introduced. Advantages and defects of various rotating beds were indicated through discussion and analysis in terms of hydrodynamics, mass transfer and power consumption. The conclusions could provide guidance for structrue selection in different separation processes. A wider range of ideas are presented for rotor structrue design and optimization in the future. In the end, the insufficiency of present mechanical researches on rotating bed and the necessity for rotor structure design and optimization from the perspective of basic principle are indicated.

Key words: higee rotating bed, separation, hydrodynamics, mass transfer, power consumption, higee rotating bed, separation, hydrodynamics, mass transfer, power consumption
