In this work, Sauter mean diameter (SMD) and drop size distribution (DSD) are investigated in an eductor liquid-liquid extractor. The water/toluene liquid-liquid extraction (LLE) system was applied in the experiments. The jet length, the existence of venturi, the throat to nozzle area ratio, the projection ratio, and two phases flow rate ratio investigated in the experiments. Results show that for different nozzle diameters, from 1 to 3 mm, the same maximum jet length appears. Velocity range of formation was much wider for smaller nozzle diameters. Existence of venturi in front of nozzle reduces the SMD and produces narrower and symmetric DSD. Decrease of throat to nozzle area ratio and projection ratio decrease SMD and produce narrow and more symmetric DSD. Increase of two phases flow rate ratio increases the SMD trivially, and does not effect on DSD. A power law model was fitted to predict SMD. N-T model could predict DSD appropriately, while normal and log-normal models don’t fit well with the experimental data. The two parameters of N-T model were correlated, one with SMD and the other one with operational and geometrical parameters of equipment.

在这项工作中，在喷射器液-液萃取器中研究了索特（Sauter）的平均直径（SMD）和液滴尺寸分布（DSD）。实验中采用了水/甲苯液-液萃取（LLE）系统。在实验中研究了射流长度，文丘里管的存在，喉管与喷嘴的面积比，投影比和两相流速比。结果表明，对于从1到3 mm的不同喷嘴直径，将出现相同的最大喷嘴长度。对于较小的喷嘴直径，形成速度范围要宽得多。喷嘴前部文丘里管的存在会降低SMD并产生更窄且对称的DSD。喉管对喷嘴面积的比率和投影比率的减少会降低SMD，并产生狭窄且更对称的DSD。两相流量比的增加会使SMD轻微增加，并且不会影响DSD。拟合幂律模型以预测SMD。NT模型可以适当地预测DS​​D，而正常和对数正态模型与实验数据不太吻合。NT模型的两个参数相互关联，一个与SMD相关，另一个与设备的操作和几何参数相关。
