Pitched Blade Turbine Efficiency at Particle Suspension

Popis výsledku v původním jazyce

This paper deals with effect relative impeller size and particle content on the efficiency of a pitched six-blade turbine at particle suspension.Two pitched six-blade turbines were used in model measurements of just suspension impeller speed. The ratiosof the vessel to agitator diameter D/d were 3 and 4.5. The measurements were carried out in a dish-bottomed vessel 300 mm in diameter. The just suspension impeller speeds were measured using an electrochemical method, and were checked visually. A 2.5 % NaCl water solution was used as the liquid phase, and glass particles with four equivalent diameters between 0.18 and 0.89 mm and volumetric concentration from 2.5 % to 40 % were used as the solid phase. The criterion values ?(s) were calculated from theparticle suspension and power consumption measurements. The dependencies of ?(s) on particle content c(v) show that larger agitators are more efficient for higher particle content.
