摘　　要：为优化铀溶剂萃取过程中混合澄清器搅拌桨的设计参数,在TRPO/P204/TBP/煤油体系中,采用正交设计方案,研究了搅拌桨各因素对溶剂萃取铀的影响。结果表明:影响铀萃取率的因素由主到次的顺序为桨槽长度比>搅拌速度>桨型>安装高度>宽径比>叶片数;极差分析结果表明,最优搅拌桨型及搅拌参数为弯叶桨型,桨槽长度比0.875,搅拌速度375r/min,桨叶4片,搅拌桨安装高度70mm,宽径比0.2;最优条件下,铀萃取率高达97.36%。In order to optimize the impeller of mixer-settler used in the process of uranium solvent extraction,using TRPO/P204/TBP/sulfonated kerosene system,the influence of various factors of impeller on the extraction of uranium was researched by orthogonal design.The results show that the factors affecting the extraction rate of uranium are as follows：impeller length-to-chamber length ratioagitation speedimpeller typeinstallation heightimpeller width-to-diameter ratioblade number.The optimal impeller type is curved blade and stirring parameters are impeller length-tochamber length ratio of 0.875,agitation speed of 375 r/min,blade number of 4,installation height of70 mm,impeller width-to-diameter ratio of 0.2.Under this condition,the uranium extraction is as high as 97.36%.
