摘　　要：根据实际生产中的物料提纯工艺要求,完成了一种新型多功能设备的研发设计,该设备同时具备混合萃取、再化浆洗涤和过滤分离3种操作功能,并引入了超声力场与动态搅拌离心耦合,以强化其在前3种功能操作中的传质与分离效果。为了进一步验证超声作用的影响,运用流体力学计算软件建立了搅拌洗涤过滤釜的三维计算模型,分别从搅拌混合过程和动态过滤过程2个方向进行数值模拟计算,研究了在以上2个过程中的操作条件对混合或过滤规律的影响。对实验研究和实际生产过程提供了指导作用。Based on the requirements of purification process of the production materials,a new reactor was designed and proposed in this paper,with three functionalities： mixed-pulp,washing-filter and separation. In order to improve mass transfer and filteration effects,ultrasound probes was employed to enhance liquid turbulence intensity. To validate the effectiveness of ultrasound,several 3D computational models were built through Fluent for numerically simulating the mixing-washing process and dynamic filtration process. With the established model,the operating conditions of the mixing and dynamic filtration process stage are calculated,which provides useful information for experiment research and actual production.
