摘　　要：利用空气 水 SO2 系统研究了逆流旋转床的气相压降及传质特性。结果表明 ,填料A(普通丝网 )比填料B(RS钢波纹丝网 )的气相压降大 30 %左右 ,体积传质系数小 1 5%左右 ,即填料B比填料A的流体力学性能和传质性能好。With an air water SO 2 system, the characteristics of the pressure drop and mass transfer in RPB have been studied. Results show that the gas pressure drop of packing A (normal metal wire packing ) is about 30% higher than that of packing B (wave wire packing).The volume mass transfer coefficient of packing A is about 15% less than that of packing B. In other words, the characteristics of hydromechanics and mass transfer of packing B is better than that of packing A.
