Abstract
An apparatus for mixing a liquid and a gas in a tank includes a means for circulating the liquid in the tank and a sparge ring for dispersing gas into the tank. The circulating means includes a plurality of blades extending downwardly from a bottom surface of a disc so that rotation of the blades creates a suction area. The sparge ring introduces gas into the tank in a direction that bypasses the suction area to prevent the gas from flowing into the suction area. Preferably, the sparge ring has a discharge means with a radius that is larger than the distance from the center of the disc to the outer tips of the blades.
Claims8
In an apparatus for mixing a liquid with a gas including a tank with said liquid therein, a circulating means for creating a radial flow of said liquid to circulate said liquid in said tank, said circulating means comprising a rotatable shaft, a disc mounted on said shaft, and a plurality of blades extending downwardly from a bottom surface of said disc so that rotation of said plurality of blades creates a suction area, said suction area being the only suction area created by said circulating means, the improvement including:
- sparge ring means having a discharge means with a radius that is larger than the distance from the center of said disc to outer tip of said blades, said discharge means being axially positioned so as to introduce said gas into a zone extending axially downward from said disc a distance approximately equal to the height of said blades for introducing gas into said tank in a direction that bypasses said suction area to prevent gas from flowing into said suction area.
