摘要： A method and apparatus for injecting a gas into a liquid in which a rotating helical impeller within a draft tube submerged in the liquid creates a liquid flow within the draft tube. Gas bubbles are injected into the draft tube either above or below or alongside the helical impeller or in all three locations. The liquid is drawn into the draft tube with a superficial velocity greater than a substantially uniform terminal ascent velocity of the gas bubbles to allow entrainment of undissolved gas bubbles in the bulk liquid into the liquid being drawn into the draft tube. The gas bubbles are injected with a uniform diameter of between about 10.0 microns and about 1.0 millimeters. The small bubble size enhances the dissolution of the gas into the liquid and also allow the entrainment of the gas into the liquid being drawn into the draft tube.

摘要： A system and method for mixing high viscous liquids with gas is provided. The disclosed embodiments include a reactor or mixing vessel having a draft tube disposed therein, a gas injection subsystem adapted to inject gas into the reactor or mixing vessel proximate the entrance of the draft tube. The embodiments also include an agitator disposed within the draft tube which makes the draft tube the primary site for the gas-liquid mixing. In particular, the agitator is adapted to create gas bubbles having an average diameter between about 0.3 mm and 3.0 mm which are then ejected into the reactor or mixing vessel. The mass transfer efficiency associated with the present system and method is enhanced from the combined effect of gas dissolution into the high viscous liquid within the draft tube and greater bubble residence time within the high viscous liquid.

摘要： A system and method for oxygenating an aerobic sludge digester is provided. The disclosed embodiments include an aerobic sludge digester tank or vessel having a mechanically agitated contactor disposed therein, an oxygen injection subsystem adapted to inject oxygen into the digester tank proximate the mechanically agitated contactor. The embodiments of the mechanically agitated contactor include an agitator or impeller disposed within the draft tube which makes the draft tube the primary site for the gas-liquid mixing. In particular, the agitator or impeller is adapted to create gas bubbles having an average diameter between about 0.3 mm and 3.0 mm which are then dispersed into the aerobic digester. The mass transfer efficiency associated with the present system and method is enhanced from the combined effect of oxygen dissolution into the sludge and greater bubble residence time.

摘要： A dip aerator for sewage treatment plants is provided with a downwardly directed pump outlet and a pump inlet, which is connected with an air hose. The pump inlet (14) is below the water level (18) in the sewage treatment basin. The air hose (20, 24) starts out from the pump inlet (14) and extends with a specified volume below the water level. In this way, it is achieved that, when the pump is started, water is delivered initially and air is emitted only later. By these means, brief repulsions without input of air become possible.

摘要： A gas/liquid mixing device is provided in which bubbles having such a small diameter as to be invisible to the eye are produced and dissolved in water in a short time, whereby the solution of gas can be improved greatly. The gas/liquid mixing device has a mixing cylinder, a drive unit, and a gas supply means. In the mixing cylinder, a rotary vane having guide vanes is the mixing cylinder and gas supplied into the mixing cylinder so that the water flow containing the bubbles is dispersed outwardly through bubble dispersing holes formed in the wall of the mixing cylinder.

摘要： An apparatus for selectively aerating or anaerobically mixing a liquid in a container includes a hollow, star-shaped, multi-vaned rotor (6) arranged in the bottom region of the container (1) for rotation about a vertical axis. The hollow interior of the rotor at one of the two opposite faces thereof is in communication with a gas feed line (15), and each of the vanes (10) at its trailing flank (11), as viewed in the direction of rotation of the rotor, is provided with a respective gas exit opening (12). The inter-vane spaces of the rotor are open at one of its two opposite faces for admitting liquid from the container into those spaces. The rotor is surrounded by a stator (7) providing a plurality of circumferentially spaced flow channels (9) for receiving and guiding away either liquid with admixed gas when gas flows through the gas feed line or liquid without admixed gas when no gas flows through the gas feed line. The rotor is provided in its inter-vane spaces with respective guide plates (18) interposed between the gas exit openings and the liquid entry locations for shielding the gas exit openings and for preventing liquid in the intervane spaces from being sucked into the rotor through the gas exit openings when no gas is flowing through the gas feed line.
