摘　　要：以α-萘酚与对氨基苯磺酸重氮盐之间的串联竞争偶合生成单偶氮和双偶氮的反应为测试体系,研究了超重力因子、喷嘴初速、浓度、撞击间距、填料等参数对撞击流-旋转填料床(IS-RPB)反应器离集指数和微观混合时间的影响规律,得出适宜的操作参数。在相近的操作条件下,对比了IS,RPB,IS-RPB 3种反应器的微观混合性能。实验结果表明:IS-RPB反应器秉承了IS反应器和RPB反应器的优点,其微观混合性能明显优于IS和RPB等反应器,是一种具有应用潜力的新型设备。Micromixing characteristic of impinging stream rotating packed bed reactor （IS-RPB） was studied using the competitive and consecutive reaction between α-naphthol and diazotized sulphanilic acid. The influence of high gravity factor, distances of nozzles, velocities, concentration and packing on segregation index and micromixing time was investigated. Besides, IS, RPB and IS-RPB reactors were contrasted with micromixing characteristics in the same operational condition. The experimental results show that IS-RPB reactor has better micromixing characteristics than other reactors ,which has good application prospect.
