旋转泡沫搅拌反应器（RFSR）具有较高的传质效率。然而，作为其重要参数之一的微观混合效率，还需要对其进行更全面的研究，以便更好地应用和优化。因此，本文采用碘化物-碘酸盐反应体系对反应器内的微观混合效率进行了分析，并考察了反应器结构和液体粘度对微观混合效率的影响。结果表明，进料位置在转子外缘时可以获得较高的微观混合效率。每线性英寸（linear inch，RPM）具有低孔的固体泡沫和在反应器壁上装备挡板也可以显著地改善微观混合效率。结果进一步揭示了微观混合效率随液体粘度的增加而降低。根据结合模型估算的不同构型的RFSR的微观混合时间在2.1 × 10− 4 ~ 2.0 × 10−2s之间。最小值比许多传统反应器的最小值小，并且与一些新型反应器的最小值具有竞争力。此外，预测的平均能量耗散率的基础上的微观混合时间的相关性开发，这与实验值吻合得很好。结论这项研究表明，RFSR具有优异的微观混合效率，也提供了基础信息的优化RFSR及其在过程工业中的应用。© 2019化学工业协会
BACKGROUNDThe rotating foam stirrer reactor (RFSR) has shown its high mass transfer efficiency. Nevertheless, its micromixing efficiency, which is one of the significant parameters, still needs more comprehensive study for its better application and optimization. This work therefore employed the iodide–iodate reaction system to analyze the micromixing efficiency in an RFSR, and the effects of reactor configuration and liquid viscosity on micromixing efficiency were investigated.RESULTSThe results show that high micromixing efficiency can be achieved when the feed location is at the outer edge of the rotor. Solid foam with low pores per linear inch (ppi) and equipping baffles on the reactor wall can also considerably improve the micromixing efficiency. The results further reveal that the micromixing efficiency decreased with increasing liquid viscosity. Micromixing times in an RFSR with various configurations, estimated based on the incorporation model, ranged from 2.1 × 10−4to 2.0 × 10−2s. The minimum value is smaller than that of many conventional reactors and is competitive with that of some novel reactors. In addition, a correlation to predict the micromixing time based on the average energy dissipation rate was developed, which agreed well with experimental values.CONCLUSIONThis study indicates that the RFSR has excellent micromixing efficiency and also provides fundamental information for optimization of the RFSR and its application in process industries. © 2019 Society of Chemical Industry
