摘要(Abstract)：

螺旋盘管反应器无内插件及扰流部件,通过流体流动过程产生的二次流来提高微观混合效果,比较适合于黏性流体混合过程。今采用碘化物-碘酸盐平行竞争反应体系为工作体系,以甘油调节体系黏度,对螺旋盘管反应器内黏性体系的微观混合性能进行研究。考察了物料体积流量、H+浓度、体积比、体系黏度、盘管内径对微观混合性能的影响,并与内径及有效长度相同直管的微观混合性能进行对比研究。结果表明,在实验研究范围内,提高物料体积流量可以增强混合效果,随H+浓度增加,离集指数显著增大。反应物摩尔比相同的前提下,微观混合性能随体积比增加而变差。随体系黏度增大,微观混合性能降低。减小螺旋盘管内径,微观混合性能提高,与直管相比,螺旋盘管反应器微观混合效果明显增强。
