In this study, as an alternative for the traditional stage equipment in lithium extraction industry, the two-phase hydrodynamics of a ceramic hybrid pulsed column was investigated with the high-viscosity actual lithium extraction system. The results indicated that the pulsation intensity was the critical operating parameters, which had a decreasing effect on the Sauter mean diameter. This led to the generation of different operating regimes directly, namely, the mixer-settler regime, dispersion regime and emulsion regime. The dispersed phase holdup had a decreasing trend with the pulsation intensity in mixer-settler regime, while the variation was increasing in the dispersion regime. Meanwhile, the dispersion regime and emulsion regime had narrower droplet size distribution, smaller Sauter mean diameter and lower characteristic velocity. Although the two-phase superficial velocities also had effects on the column hydrodynamics, the influence was not crucial compared to that of pulsation intensity. Empirical correlations were determined to be reasonable for calculating the holdup and droplet diameter with the averaged deviations of 13.0% and 7.0%, respectively. However, the regressed parameters reminded that the effects of the two-phase physical properties can't be ignored on the column hydrodynamics and they should be taken into account adequately for the design of extraction columns.

在本研究中，作为锂提取行业传统阶段设备的替代品，利用高粘度实际锂提取系统研究了陶瓷混合脉冲柱的两相流体动力学。结果表明，脉动强度是临界操作参数，它对索特平均直径有减小的影响。这直接导致了不同操作方式的产生，即混合器-沉降器方式、分散方式和乳液方式。分散相滞留量在混合器-沉降器状态下随脉动强度呈下降趋势，而在分散状态下变化增加。同时，分散状态和乳液状态具有更窄的液滴尺寸分布、更小的Sauter平均直径和更低的特征速度。尽管两相表面速度也对柱体流体动力学有影响，但与脉动强度相比，这种影响并不重要。确定经验相关性对于计算滞留率和液滴直径是合理的，平均偏差分别为 13.0% 和 7.0%。然而，回归参数提醒，两相物理性质对塔流体动力学的影响不可忽视，在萃取塔的设计中应充分考虑。分别为 0% 和 7.0%。然而，回归参数提醒，两相物理性质对塔流体动力学的影响不可忽视，在萃取塔的设计中应充分考虑。分别为 0% 和 7.0%。然而，回归参数提醒，两相物理性质对塔流体动力学的影响不可忽视，在萃取塔的设计中应充分考虑。
