摘要
１前言在普通喷动床的环形区底部额外引入一股辅助气体，由于喷动气体和辅助气体各自独立地改变，气固系统将出现下列几种体系或操作状态：①固定床；②充气喷动床；③喷流床；④带射流的流化床。长期以来对充气喷动床与喷流床的区别不是很清楚的［１～５］。张怀清等［６...
In an aerated spouted bed with draft tube made of a plexiglass cylinder of 92 mm I.D. Using glass beads as experimental materials. The maximum allowable aerating rate was found. Thereby we can completely distinguish the aerated spouted bed from the spout fluid bed, both of them have not being clearly distinguished from each other for a long time. The factors relating to maximum allowable aerating rate were studied, And by regressing experimental data, the correlation used to calculate maximum allowable aerating rate was obtained, which is for design and operation reference only to the aerated spouted bed with a draft tube.
