在内径为 90 mm的搅拌萃取塔中 ,对分散相滞存率和液泛速度进行了研究 .实验用的物系为煤油 -水、煤油 - 15 %甘油水、锭子油 -水、2 -乙基己醇 -水 .实验结果表明 :转速、相比、物性对液泛速度、滞存率都有影响 ,而且在较低能耗下搅拌萃取塔处理界面张力大的物系时显示出较大优越性 .同时 ,利用因次分析法 ,得到了计算滞存率及湍流区液泛速度的关联式 In the agitated extraction tower with an inner diameter of 90 mm, the detention rate of the disperse phase and the flooding velocity were studied.The experimental systems used were kerosene - water, kerosene - 15% glycerin, spindle oil - water, 2 - Hexanol and water.The experimental results show that the rotational speed, the comparison of the physical properties have an impact on the flooding rate and the storage rate, but also shows a larger value when the stirring extraction tower is treated with a lower interfacial tension at a lower energy consumption At the same time, by using the factor analysis method, the correlation between the calculation of the retention rate and the flooding velocity in the turbulent zone has been obtained
