ABSTRACT:
An apparatus for mixing a gas and a liquid is disclosed. The apparatus is comprised of a hollow outer tube and a hollow inner tube received coaxially within the outer tube. The inner tube is mounted for rotary motion within the hollow interior of the outer tube. A motor is attached to the outer tube adjacent a first end thereof and is drivingly coupled to a first end of the inner tube. The inner tube has a section which extends beyond the second end of the outer tube. A propeller is attached to this section of the inner tube for rotation therewith. The propeller is adapted to be placed in a liquid and to propel the liquid in which the propeller rotates. An inlet is formed in the inner tube for admitting a gas to the hollow interior of the inner tube. A diffusion tube forms a portion of the inner tube and extends beyond the propeller. The diffusion tube has a hollow interior which forms a portion of the hollow interior of the inner tube. The diffusion tube also has an open end for injecting a gas passing through the hollow interior of the inner tube into a liquid in which the propeller is placed. The diffusion tube has a length which is at least fifty percent of the transverse dimension of the propeller.
