| titleOfInvention | Method and means for dissolving gas into liquids |
| abstract | 836,294. Sewage and water treatment. INGERJORSFIRMAN FLIESBERG A. B., and MEYER, F. Feb. 28, 1958 [March 6, 1957; Nov. 26, 1957], No. 6589/58. Classes 46 and 111. [Also in Groups VI and XII] In a continuous method of aerating sewage, lake water &c. the water &c. is circulated through a vessel 1, Fig. 1, and introduced through nozzles 6 set at a small angle with respect to the upper surface and at a distance from the axis of the vessel so that the surface is beaten to a foam and the liquid caused to rotate about the axis of the vessel and to move downwards in a helical path towards a withdrawal point 9 at a lower portion of the vessel. The nozzles 6 may comprise pipes 5, Fig. 2, arranged tangentially to circles of different radius and having flattened ends which splay the liquid into drops. Alternatively the nozzles 12, Fig. 4, may be arranged fanwise about a central supply pipe 11 or as shown in Fig. 10 downwardly directed tubes 24 may carry cup-shaped members 25 which spread the jets to fan-like shape and are arranged at different heights to bring about a uniform dissolution at different levels. A stationary or rotatable mandrel 10 is fitted in the vessel to prevent a gas filled vortex from reaching the outlet 9. The air is supplied to the vessel through pipes (not shown) and a constant liquid level may be maintained in the vessel by a vent pipe 17 and bleed opening 19 which allow a negligible flow of liquid to escape when the level is high and allow gas to escape at high speed when the level is low. Further correction is obtained at the change in dissolution rate of the gas as the liquid level changes. In a modification the apparatus may be used to circulate liquid in larger containers which may be open or closed to the atmosphere. In one example the vessel 1<SP>11</SP>,Fig. 6, is open-ended and arranged within a container 27 through which the liquid is circulated by a pump 30 driven from a motor 31 arranged outside the vessel. In another example the vessel is supported by floats 48, Fig. 8, in a sewage basin and is continuously supplied with sewage mass by a pump 46 connected to a rubber hose 47 which may be moved to any part of the basin. |
