Abstract

1465801 Dispersing gases in liquids; froth flotation apparatus OUTOKUMPU OY 3 June 1974 [5 June 1973] 24480/74 Heading B1C and B2X In a method of dispersing a gas in a liquid or slurry, (e.g. for froth flotation) by means of a rotor within a stator, the increase in hydrostatic pressure with increasing depth is compensated by a hydraulic pressure correspondingly changing with depth in order to keep the total liquid pressure substantially constant over the surface over which the gas is dispersed; this is done by arranging for the ring of liquid between the rotor and stator to increase in thickness with depth so that the centrifugal force acting on the liquid ring produces the compensating dynamic pressure. As shown in Fig. 1 gas is supplied through a hollow shaft and dispersed through passages 5 between which are "grooves" 8 through which the slurry circulates; the envelope of the rotor is cylindrical while the stator is shaped so that the clearance between them increases downwardly. In other embodiments the rotor may narrow downwardly while the inner envelope of the stator is cylindrical, or both may increase in diameter downwardly with increasing clearance (Figs. 4-7, not shown). In Fig. 1 the "grooves" 8 are closed at the bottom, but they may be open at both ends or shrouded at the top (see Figs. 2 and 3, not shown). The gas passages 5 in the rotor may be omitted (Fig. 8, not shown) and the gas introduced above the rotor through a downcover surrounding the rotor shaft (Fig. 12, not shown).
