Influence of floating suspended solids on the homogenization of the liquid phase in a mixing vessel
The impact of floating suspended solids on the homogenization of the liquid phase in a stirred vessel was studied. The experiments were performed in a tank with an internal diameter of 0.32 m, equipped with a 45° pitched four-blade turbine (PTD) placed at varying positions in the vessel. Tap water was used as the liquid phase and polyethylene particles (PEHD) were used asthe solid phase. The impeller speed was varied from N = 200-900 rpm. The mixing time of the suspended system was measured by a conductivity technique using a sodium chloride solution as the tracer, whereas power consumption was measured by the torque table. The influence of mean concentration of the suspended floating solids, average particle size, surface tension at the liquid/air interface and impeller diameter and its position on the mixing time and power consumption were analyzed.
