| Abstract: | Simulated and optimized the acetamiprid crystallization reactor based on computational fluid dynamics （CFD）, investigated the velocity distribution uniformity and the crystal volume fraction distribution uniformity under differ-ent agitation speeds. The results showed that the SP306 axial flow impeller with high efficiency had good effects on the crystal suspension, the stirring rate had a significant effect on the crystal volume fraction distribution unitbrmity, and the optimized stirring rate was 90 r/min. The industrial application of SP306 verified the rationality of the optimum design, and the distribution of product size was improved obviously. |
