Abstract

The conditions are studied in the paper of flooding the six plane blade impeller with blades inclined at the angle of 45° of relative size <i>d/D</i> = 1/3 and relative distance from the bottom of cylindrical vessel <i>H<sub>2</sub>/D</i> = 1/3 equipped at the wall with four radial baffles of width <i>b/D</i> = 0.1 at the relative vessel filling <i>H/D</i> = 1. The flooding conditions are determined experimentally from the course of dependence of the power input ratio of gassed and ungassed impeller on the flow rate number of air blown into the liquid phase (water) in the vessel. Theoretically, the conditions of the impeller flooding, when it is no more able to disperse air blown into the charge, are determined from balance of forces in the liquid flow leaving the region of rotating impeller acting on the bubbles of rising gas under the turbulent regime of charge flow. The results of the blade impeller frequency of revolutions determined theoretically at its flooding were found to be in good agreement with the experimentally determined values of the frequency of revolutions investigated obtained in the model equipment with vessel diameter <i>D</i> = 290 mm.
