STUDIES ON TRANSFER PROCESSES IN MIXING VESSELS - POWER-CONSUMPTION OF THE MODIFIED RUSHTON TURBINE AGITATORS IN 3-PHASE SYSTEMS

In this work, the modified blade turbines, with the surface fraction o f the perforations equal to 0.353, are used in the study of the relati onship between the power consumption in three-phase systems and the su perficial gas velocity, mixing intensity, agitator type, solid particl es concentration, physical and theological properties of the suspensio ns. The power consumption in three-phase mixing with modified turbines , single and double, is approximately 40% smaller than for the standar d turbines at the same mixing intensity. The modified blade turbines a re simple to manufacture and do not require any modification in electr ical motor and drive assemblies.
