Fan Zheng, Wang Hongzhi and Xue Fan (Institute of Chemical Metallurgy, Academia Sinica, Beijing)This paper deals with certain important functions of liquid-liquid dispersion dynamic behaviour in contactors. The probability of drop breakage, critical vibrating frequency and daughter drop number distribution have been studied in a vibrating plate tank. Their correlations have been obtained based on both theoretical analysis and experimental results. In addition, mean drop size was measured by the laser parallel light trans-mittance method. The effect of vibrating frequency and amplitude on Sauter diameter were also investigated.
摘要： 本文主要对液液分散动力学中的某些重要函数,进行了实验研究.在理论分析及实验数据的基础上,对振动筛板槽中的液滴破碎概率与振动频率、振幅、液滴直径、体系的物理性质以及筛板孔径的关系,进行了关联.探讨了液滴可能发生破碎的临界条件,并根据实验结果,建立了液滴在发生破碎后子滴数的关系式.此外,采用激光平行光技术并与微机结合,在线测量Sauter液滴直径.实验结果与理论计算值相近,并研究了振动频率与振幅对液滴直径的影响.
