Abstract
In this paper, the optimum structural dimensions of a reaction stirred tank were determined to further enhance the cleaning effect of impurity chloride ions in a wet process for the production of electrolytic zinc from zinc sublimates. Chloride ions contained in the leachate are removed by the addition of copper powder, while the cleaning effect is determined by the distribution of copper powder in the stirrer. For the determination of the optimum structural dimensions, the hydrodynamic analysis was carried out using Fluent 17.1. The standard k-e model was used as the viscous model in the multi-reference system, the silmon model as the turbulent dissipative force model and the Gidaspow model as the interfacial drag force model with the model developed in Solidworks 2018. Using this model, the optimum structural dimensions of the impeller were determined, with the best effect of chlorine cleaning in the impeller when the impeller diameter was 1.0 m, height 1.5 m, baffle size 0.2×0.9×0.01 m, baffle size four symmetrically, impeller diameter 0.4 m, impeller diameter 60 mm, impeller angle 45°, bed height 0.225 m, rotational speed 150 rpm, and clockwise rotation.
