    摘要： Apparatus for contacting a liquid, in a tank (10) containing a body of same, with a gas. A generally tubular draft member (21) containing an axial down-pumping helical screw impeller (32) is oriented in the tank with its central axis aligned vertically. Means (29, 35, 38) are provided for introducing gas into liquid flowing downwardly to the helical screw impeller to form a two-phase gas-liquid mixture which is pumped through the draft member (21) by the impeller (32) to induce circulation of liquid discharged from the draft member liquid outlet through the body of liquid in the tank to the draft member inlet, thereby effecting gas-liquid contacting.

    摘要： Apparatus for contacting liquid, in a tank (10) containing a body of same, with a gas. A generally tubular draft member (21) containing an axial downpumping impeller (32) is oriented in the tank with its central axis aligned vertically. Liquid flow restriction means (27) are positioned proximate the draft member liquid inlet (28) above the impeller and restricting cross-sectional liquid flow area of the liquid inlet to from 0.50 to 1.10 times cross-sectional area of the draft member. Gas flow passage means (29, 35, 38) are provided having an inlet opening exposed to a source of gas and an outlet positioned proximate to the liquid flow restriction means in liquid flowing to the axial pumping impeller means, whereby liquid flowing through the liquid flow restriction means under action of the axial pumping impeller is mixed with gas from the gas flow passage means to effect gas-liquid contacting in the liquid pumped by the axial pumping impeller.

    摘要： Apparatus for contacting a liquid, in a tank (10) containing a body of same, with a gas from a gas space (36) overlying the body of liquid. A generally tubular draft member (21) is disposed in the tank (10), having a cylindrical main body portion and an outwardly flared conical inlet upper section (24) forming a liquid inlet at its upper end. Enclosing walls of the conical inlet section form an angle with the draft member central axis of from 5° to 35° and the conical inlet section (24) has a vertical height of from 0.25 to 1.25 times diameter (D) of the draft member (21). A rotatable axial pumping impeller (32) is provided in the draft member (21) for rotational vortex entrainment of gas (31) in downwardly flowing liquid pumped through the draft member (21). Baffle means (40) are positioned in the conical inlet section (24) of the draft member (21) to prevent bulk rotation of liquid in the tank (10) during rotation of the impeller (32).
