综述了混合澄清槽中水油两相相比(流比)变化对混合室内液滴分散、目标组分传质及澄清室内两相分离影响的相关研究,讨论了相比变化时搅拌桨桨型与安装位置对混合室和澄清室性能的影响,对混合澄清槽今后的发展如何适应更宽的操作相比及强化混合室高效混合、澄清室快速澄清进行了探讨.
Effect of the change in aqueous-to-organic phase ratio on the performance of mixer-settler was summarized.The effect of aqueous-to-organic phase ratio on drop dispersion,mass transfer of target metal ion between phases in mixer chamber and phase separation in settler chamber were paid particular attention.In addition,the effect of impeller type and installation position on the performance of mixer-setter were discussed.How to meet the requirement from a wide aqueous-to-organic phase ratio in mixer-settler was suggested for complex separation.Future development of mixer-settler was indicated,including how to achieve high mixing efficiency in mixer chamber and high clarification efficiency in settler chamber under a wide aqueous-to-organic phase ratio range.
