摘　　要：以饱和的NaCl水溶液为示踪剂,采用脉冲法考察了液体流量、转子转速对旋转填料床与盘管组合反应器停留时间分布(RTD)曲线的影响。用轴向扩散模型对流动状况和返混程度进行了表征。结果表明,组合反应器内的流体流动型态与盘管相同,接近活塞流,且流量越大,平均停留时间越短。旋转填料床转子转速对组合反应器停留时间分布影响很小。A new type reactor, composed of rotating packed bed （RPB） and coil pipes, is designed, and its residence time distribution （RTD） is investigated by using pulse method and saturated NaCl solution as tracer at different flow rates and rotating speed, axial dispersion model is used to represent flow status and back-mixing. The results show that the flowing state of the fluid in combined reactor is similar to the tubular which approaches plug flow, and residence time decreases with increasing flow rate. But the rotor speed of RPB has little effect on the RTD.
