摘　　要：采用空气-羧甲基纤维素钠水溶液-固体物料体系,对漩流鼓泡塔反应器的气液传质性能进行了研究。在常温(20℃)、常压、非牛顿流体条件下,测试了反应器的平均气含率,漩流鼓泡塔反应器分别装有直板型和弯板型(3种直径)气体喷流器。由实验数据回归得出平均气含率与流体性能、空塔气速之间的关联式。与直流鼓泡塔反应器相比,漩流鼓泡塔反应器的平均气含率较高,其中CBⅡ型漩流鼓泡塔反应器比直流鼓泡塔反应器的平均气含率高20％左右。A new type reactor-rotating bubble column reactor(RBC reactor) used in gas-liquid-solid system was presented. The gas holdup (εG) of the RBC reactor in a non - Newtonian flow was studied. A correlation between gas holdup and gas rates,rheological properties of aqueous CMC solution was obtained. The correlation can be used for reactor scale - up purpose. The rotating bubble column reactor was efficient for gas - non -Newtonian flow-solid systems.
