抄録

The hydrodynamic characteristics and extraction performance of a multistage liquid-liquid extraction column with a novel impeller which is equipped with static mixers on a disc are study experimentally.<BR>The holdup of the dispersed phase varies along the height of the column. The holdup at the first stage of the column increases with increasing dispersed phase flow rate. It decreases in the region of low flow rate of the dispersed phase and high impeller speed, and increases via a minimum value in the region of high flow rate of the dispersed phase and heigh impeller speed, and increases in the region of low impeller speed with increasing continuous phase flow rate. It also increases in the region of low flow rate of the continuous phase, and decreases via a maximum value in the region of high flow rate of the continuous phase with an increase in impeller speed. In the other stages, the holdup increases with increasing dispersed phase flow rate and impeller speed. However, the effect of continuous phaseing flow rate on hold up is not significant. The dispersed flooding flow rate increases with increase continuous phase flow rate and then decreases via a maximum value with the impeller speed.<BR>The theoretical stage number per unit column height increases with increasing total flow rate of dispersed and continuous phase, and then decreases via a maximum value with the impeller speed. The performance is evaluated by the theoretical stage number per unit column height and is somewhat higher compared with those of other extractors in the literature. The meshwire setted on the stator rings has a remarkable effect on extraction efficiency, and is found to have the function of settling of dispersed phase.
