摘要

从减小液滴内传质阻力、提高两相间传质速率和改善混合室中两相的停留时间分布等方面对油分散型单混合室混合澄清萃取器(OWSMMS)的设计进行了改进

设计了水分散型多隔层混合室混合澄清萃取器(WOMMMS)以提高混合澄清萃取器的分离效率.在实验中分别应用OWSMMS和WOMMMS进行稀土分离

比较了它们的操作性能.在实验条件下

通量为1.46～2.92m~3/(m~2·h)时

轻/重稀土的相对分离效率比β_(qz)为1.426

相邻元素的相对分离效率比β_(ab)一般都大于1

说明WOMMMS的操作性能明显优于OWSMMS.

Abstract

A new design of mixer-settler is presented. The mixer has several mixing chambers in series and with water dispersed in oil in the mixer. The mixer with several mixing chambers in series can improve the residence time distribution of both phases in the mixer significantly. The dispersion of water in oil can increase the rate of mass transfer. The new design also has the advantages of low backmixing in the mixer and very little intrastage and interstage short circuiting. Both the new design and the existing mixer settler in which mixer is a single mixing chamber with oil dispersed in water in the mixer were used to separate rare earth elements totest their performance. Laboratory results indicated that the ratio of efficiency for the separation of light group and heavy group of rare earth elements is 1. 426 and the ratio of efficiency for the separation of two neighbouring rare earth elements is mostly greater than 1 when the flow capacity is between 1. 46 and 2. 92m3/(m2·h).
