摘      要：The rotating jet bed(RJB) has been developed by Zhejiang University of Technology,as a noveler type of gas-liquid mass-transfer unit than rotating zigzag bed(RZB).The rotor of RJB is composed of perforated concentric baffles fixed to a rotating *** top of the baffles is in the grooves of the stationary disc,preventing short cut of the *** of total reflux distillation with RZB and two types of RJB were carried out with ethanol-water systems at atmospheric *** two types of RJB are with rotor of mesh baffles and of shutter baffles,*** results showed that the number of theoretical plates per meter of RJB,lower than that of RZB,increased with increasing rotational speed,and increased firstly and then decreased with increasing gas superficial *** maximum number of theoretical plates per meter is 40.7 for RJB with rotor of mesh baffles and 40.0 for RJB with rotor of shutter *** specific pressure drop of RJB was far less than that of *** gas phase film volumetric mass-transfer coefficients of RJB with rotor of mess baffles and shutter baffles were correlated with the Reynolds number,Grashof number and Schmidt *** calculated value agreed well with the experimental value,and the average deviation was less than 15%.
