Abstract

The design of impellers for chemical reactor agitators directly influences mixing efficiency and process quality. Traditional impeller designs often fail to meet the requirements of multi-objective optimization, especially in improving mixing efficiency, reducing energy consumption, and enhancing operational stability. This paper proposes a multi-objective optimization approach for performance optimization of agitator impellers. By combining numerical simulation with experimental data analysis, the effectiveness of different impeller types during the optimization process is investigated. Comparisons of mixing efficiency, energy consumption, and stability before and after optimization reveal that the optimized impeller improves mixing efficiency while effectively reducing energy consumption. The research results provide new insights and methodologies for the design of chemical reactor agitator impellers, demonstrating significant engineering application value.
