To the special requirements of Polymer Chemical Industry, a kind of new type co-axial combined impeller was presented. Experimental investigation on mixing property of the impeller were performed, compared with the two-layer turbine and the anchor paddle, and the fluid field velocity distribution was studied with the PIV system. The result shows that mixing time of the combined impeller was reduced about 48.53% compared with two-layer turbine's, and also uniform mixing was obtained in CMC solution. In the same Pv, the mixing efficiency of the combined impeller was six times than anchor paddle's, four times than two-layer turbine's; In the same speed and diameter, the quantity of fluid flow of the combined impeller was improved about 57.4% than the two-layer turbine's. The property on axial discharging fluid of the combined impeller was better than radius's; when the outer gate paddle was rotating, the vortices radius of the mixing solution become lager. |
