摘要： A submerged aeration apparatus has a hollow shaft extending downwards from the surface of a body of liquid. The hollow shaft is used to transfer surface air or other gases to the body of liquid. An outlet for gas near the bottom end of the shaft is positioned below the surface of the body of liquid. An impeller connected to the shaft near the outlet for gas has an aperture adjacent the shaft for drawing liquid towards the impeller and circulating the liquid past the gas outlet for mixing the liquid with the gas, the impeller then expelling the liquid.

摘要： A driven hollow shaft carries propeller means in the form of a screw-shaped vane which at its lower edge widens to a chamber communicating through a channel with the interior of the hollow shaft and having an outlet opening through which gas supplied through the hollow shaft is discharged into a liquid in which the propeller means are immersed. The chamber is formed by two downwardly diverging screw-shaped surfaces of the vane and has a V-shaped cross section with the apex pointing outwardly from the driven shaft.

摘要： Apparatus and propeller for dispersing and entraining a fluid, particularly a gas, in a liquid. The apparatus includes a propeller shaft mounted for rotation, said shaft being closed at one end and having a channel therein communicating at the other end with the fluid to be dispersed, means for rotating the shaft, at least one series of diametrically aligned screw-propeller blades equidistantly spaced around said shaft extending radially from said shaft, and a plurality of diametrically aligned aspirator tubes disposed proximately to said blades equidistantly spaced around said shaft, each of said tubes having a free end disposed generally radially outwardly at least as far as the outer portions of said blades, each of said tubes having a generally longitudinally extending opening formed therethrough, each of said openings being disposed in fluid communication with said channel, and each of said tubes being mounted on said shaft to form an included angle between the longitudinal axis of the opening adjacent the free end thereof and the longitudinal axis of the shaft of not less than 35* nor more than 75*. Each of the tubes is also mounted on said shaft to form an included angle between the longitudinal axis of the opening adjacent the free end thereof and a radially extending plane having the longitudinal axis of said shaft lying therein of not less than one-half degree nor more than 3*. The method of dispersing and entraining fluids in a liquid comprises generating a columnated current of liquid within a body of liquid, creating one or more zones of reduced pressure in the body of liquid adjacent the outer periphery of said columnated current of liquid and rotating said zone or zones about the outer periphery of said columnated current of liquid, introducing a fluid into said body of liquid adjacent the outer periphery of said columnated current of liquid and forming minute globules or bubbles of fluid adjacent the outer periphery of said columnated current of liquid, and entraining said globules or bubbles of fluid within said columnated current of liquid.

摘要： The invention relates to an aeration device (20) for aeration of a liquid. The aeration device comprises a plate (30) of a first material, said first material being permeable to air, said plate having inlet means (31) for inletting air into the plate and means for creating a flow of liquid across the plate of the first material, when said aeration device is immersed or submerged in a liquid. The plate of first material is stationary within the aeration device. The aeration device may moreover comprise a disc (12) arranged for being placed in parallel to the plate, but leaving a gap between the plate and the disc member, and the means for creating a flow of liquid across the plate of the first material may comprise means for rotating the disc member around a central axis through the disc member. Small or very small bubbles of air may be generated by the combination of air permeable material and creation of a flow across the plate.

摘要： An injector (10) for injecting gas into a molten metal. The injector (10) has a rotor (11) that is rotatable about an axis of rotation, the rotor (11) having a cylindrical projection-free side surface (14), a bottom surface (21), and a cavity (18) for receiving molten metal located centrally of the rotor (11) with respect to the axis of rotation. The rotor (11) is provided with a plurality of openings (23) in the side surface (14) spaced around the rotor (11) for ejecting molten metal and gas from the rotor (11) upon rotation of the rotor (11) about the axis of rotation. At least one opening in the bottom surface (21) communicates with the cavity (18) permitting entry of molten metal into the cavity (18), and a plurality of passages (22) disposed in the rotor (11) interconnect the cavity (18) and the openings (23) in the side surface (14). A gas passageway (30) introduces gas into molten metal present within the rotor (11) but lacks direct communication with the cavity (18), and is provided with at least one outlet (35) opening into at least one of the plurality of passages (22) to ensure regular and even gas distribution. The invention also relates to a molten metal degassing apparatus comprising a through-like container for conveying a molten metal from an inlet to an outlet, and at least one gas injector (10) of the above-mentioned kind.

摘要： An axial flow mixing impeller system (10) for efficient mass transfer by control of size of the bubbles of the fluid which is being dispersed is obtained by creating passageways (5) through the impeller blades for flow between the suction (48) and pressure (46) sides of the blades which disrupts the flow over the suction sides of the blades thereby reducing the tendency for bubbles to grow into large bubbles which instead of being dispersed, rise to the surface without effective mass transfer to the liquid. The blades (24, 26, 28) may be slotted inwardly from the tips (52) to provide the passageways or may be formed from segments (114, 116, 118), gaps between which provide the flow passageways. The segments may be in edge-to-edge abutment. Gas-to-liquid dispersion may be improved by sparging below the impeller at the bottom of the tank and between the impellers in the tank, enabling gas supply as different pressures.
