摘要： 本文在无传质条件下研究了开孔转盘塔(RPDc)内乳液—水体系(W/O/W)的流体力学性能。测定了塔内分散相滞存率x,考察了塔几何条件及操作条件对分散相滞存率x及特性速度U_o的影响。采用因次分析法,建立了x及U_o与塔几何条件及操作条件间的经验关联式。并采用摄影法,对分散相液滴直径及其分布进行了初步研究。实验结果表明,分散相液滴直径的分布可用上限对数正态分布来描述。

Abstract: Hydrodynamic behaviors of rotating perforated disk column(RPDC) were studied with an emulsion-water system. The emulsion was dispersed in water and its holdup was measured. The effects of column dimensions and operating conditions on holdup and characteristic velocity were studied. By using dimensional analysis, the authors obtained two experimental correlations for estimating holdup and characteristic velocity respectively. Drop size distributions were studied photographically. The experimental results showed that drop size distributions could be described by upper limit log-nomal distribution.
