Structural optimization and performance study of hydrogenation stirring paddle

Abstract The agitator tank is a type of reaction vessel widely used in various industries, such as chemical engineering. In this study, the structure of the three-layer blade agitator was optimized by controlling variables, and the changes in the fluid area and the suction rate of the self-suction blade during the agitation process were investigated. Using the numerical simulation analysis method, the rotation direction of the blades, the total height of the blades, and the position of the self-suction blade were changed as three factors. The FLUENT software was used to conduct simulation analysis on the agitators with different structures to obtain visualized data. The orthogonal experimental variance analysis was performed on the obtained data to determine the magnitude of the influence of each factor on the suction rate of the self-suction blade. The study found that among the three factors in this experiment, the position of the self-suction blade had the greatest impact on the suction rate, followed by the total height of the blades, and finally the rotation direction of the blades.
