摘　　要：超重力液-液接触过程强化是一个崭新的研究领域,文中详细阐述了实现超重力液-液接触的撞击流-旋转填料床(IS-RPB)装置的结构及其接触和反应过程机制,着重介绍了混合过程和机制原理、混合特性的实验表征,并与常用混合器的混合效果进行了对比。从应用研究方面,分别介绍了IS-RPB在液-液萃取、液膜分离方面的基础及应用研究情况,并与普通方法进行了比较;从反应工程的角度,分析了超重力液-液反应过程及在超细粉体制备等方面的研究应用进展。对该技术今后的研究方向及发展进行了预测。Impinging Stream - Rotating Packed Bed （IS-RPB） as a new study field for high gravity to intensify process of liquid-liquid contact and its process mechanism are presented. The mixing process and its principle as well as experimental effect are introduced in particular. The mixing effect is contrasted between IS-RPB and general mixing sets. Based on IS-RPB separation application and contrast to general ways, the basic research and application study for liquid-liquid extraction and liquid membrane separation are discussed. According to chemical reaction engineering, IS-RPB is a feasible reactor for liquid-liquid two phase reaction, and it, as a reactor, can be used to prepare ultra-fine powder. The development direction and progress of IS-RPB are prospected.
