摘　　要：根据流态化分级与液体蒸馏间的类似性，以石英砂和聚氯乙烯粉为试验物料，对流态化床中稀相与浓相颗粒浓度间的平衡关系进行研究，得出稀浓相颗粒浓度的平衡曲线，平衡浓度与流化气速的相关曲线，推导了分离因子的表达式。ased on the similarity between the fluidezation classification and liquid distillation,the titled rela- tionships are studied by using the sillca ssnd aid PVC powder as the testing materials.The equilibrium curves and the related curves between equilibrium concentration and fluidization velocity are obtained,and the expression formula of separation factor is also derived.
