摘要

液固循环移动床反应 -再生系统由上下两个或两个以上的反应室、再生室、连通管和颗粒提升管组成 .颗粒经再生室、反应室向下移动

进入输送管后被向上输送返回至再生室 .颗粒循环能力和各流股间的窜液行为是循环移动床连续操作的关键 .通过实验对该液固循环移动床的颗粒循环、斜管窜液和连接段窜液的规律进行了研究

同时建立了循环移动床的液固流动模型

并进行了模拟计算

Abstract

The liquid-solid circulating moving bed reactor is a novel one

which consists of two or more reaction chambers and a particle transport system. Particles move down from the upper reaction chamber to the lower reaction chamber through an upper conduit and to the particle transport system through a lower conduit

then are lifted from the lower chamber to the upper reaction chamber through a riser.The circulating rate of particles and the flow of liquid in the two conduit are key to the continuous operation of the reactor.In this paper

the flow behavior of liquid in the conduits and particle circulation in the reactor are studied.At the same time the flow model is proposed and verified by experiment and simulation.
