(70g) New Impeller Type for Significant Mixing Efficiency Improvement and Energy Saving



A new type of impeller has been developed demonstrating significant mixing efficiency improvement and energy saving.  The mixing mechanism and flow pattern produced are different from that of any other products in the market.  The newly developed impeller vanes don’t have surface perpendicular to the impeller rotating direction which produces vertex. Vertex flow provides little mixing and requires vessel baffles to break the vertex to improve the mixing and much more energy input is required.  The new impeller produces true radial flow pattern.  Liquid is discharged outward at various directions and flow back to the impeller from both the vessel bottom and liquid surface.  The impeller forms a centre of the flow of liquid in a vessel.  The velocity gradient is gently decreased from the impeller to the vessel body and liquid surface.  The flow pattern is easy to model and calculate for industry applications. For solids suspension applications, it presents superior satisfactory results.  Solids settled at the vessel bottom are shown to be self-cleaned.  The impeller produces minimum vertex and no baffles to the vessel are needed so maximizes the energy output for mixing.
