Definitions

  • This invention relates to an apparatus for contacting gaseous and liquid materials, especially for the aeration of liquids or dispersion of gases or vapors in liquids, and more particularly to fermenters used in'the manufacture of yeast on the aeration principle.
  • a general object of the invention is to provide an apparatus whereby gases and liquids may be contacted, which is economical of manufacture,
  • the invention accordingly comprises the features ofconstruction, combination, of elements, and arrangement of parts, which will be exemplifled in the construction hereinafter set forth and the scope of the application of which will be indiso cated in the claims.
  • 5 lfig. 1 is a sectional elevational view illustrating 3 a preferred form of the invention.
  • the present invention comprises an aerating apparatus having a perforated or equivlalent multiple gapped chamber rotatable in a g submerged position within a suitable receptacle,.
  • any suitable independent agitating means may be provided, or the vat or other liquid container may be shaped to'hinder smooth circular motion of the liquid.
  • asubmerged chamber III which consists of an upwardly tapering cone of perforated metal having a perforated cylindrical neck I I reaching up beyond the'surface of a liquid 5 mass I! in a vat [3 containing the liquid to be aerated.
  • a vertical stem or central spindle ll carrying a gear wheel or pulley l5 enables the chamber with protruding neck to be rotated at any desired speed.
  • the liquid is initially flung 10 out through the perforations it it becomes replaced by air which in turn is whirled and flung/- out and projected into the external surrounding liquid mass.
  • An apparatus for contacting a gasiform fluid with a liquid comprising in combination a reaction vessel containing a reaction mass, bailles to aid in agitating said mass and a partially submerged rotatable chamber having a film-forming upwardly converging frusto-conical portion positioned in said vessel adapted to admit a gasiform fluid in its unsubmerged portion and to expel said gasiform fluid throughout its submerged portion to form a film-like pad of the gasiform fluid on the outside surface of said frusto-conical portion substantially to eliminate friction of said mass with said chamber and uniformly to disperse said fluid throughout said reaction mass.
  • a rotatable chamber having a cylindrical portion adapted to admit a gaslform fluid and an upwardly converging frusto-conical portion adapted when submerged in a liquid uniformly to expel said fluid therein and to forms. film-like 'pad of the gasiform fluid between said frusto-conlcai portion and said liquid.
  • An apparatus for contacting a gasiform fluid with a liquid comprising in combination a vessel containing a liquid, a partially submerged rotatable body having an unsubmerged gasiform fluid admission passage positioned therein and an upwardly converging frusto-conical portion upon the outer surfaces of which portion a film-like pad of gasii'ormfluid forms, the walls of said body being perforated substantially throughout their entire area and agitating meansvbetween said body and said vessel.
  • An apparatus for contacting a gasiform fluid with a liquid comprising in combination a reaction vessel containing a reaction mass, a rotate able'chamber having an unsubmerged gasiform fluid admission passage positioned therein and an upwardly converging frusto-conical portion upon the outer surfaces of which portion a film-like pad of gasiform fluid forms, the walls of said chamher being perforated substantially throughout their entire area and means amxed to said vessel to hinder smooth circular action of said mass, said chamber being adapted when partially submerged to expel gasiform fluid through the walls of its submerged portion.
  • An apparatus for contacting a gasiform fluid with a liquid comprising in combination a reaction vessel containing a reaction mass, a r0ta table chamber having an unsubmerged gasiform fluid admission passage positioned therein and having an upwardly converging frusto-conical portion upon the outer surfaces of which portion a film-like pad of gasiform fluid forms, the walls of said chamber being perforated substantially throughout their entire area and baffles to agitate said mass, said chamber being so shaped that when partially submerged it is adapted to expel gasiform fluid evenly and uniformly throughout different zones of said mass to accommodate differences in hydrostatic pressure.
  • An apparatus for contacting a gasiform fluid with a liquid comprising in combination a reaction vessel containing a reaction mass, an upper and lower framework carrying spaced apart bailies, and a perforated chamber having an unsubmerged gasiform fluid admission passage and an upwardly converging frusto-conical portion upon the outer surfaces of which portion a filmlike pad of gasiform fluid forms partially submerged in and adapted to expel fluid uniformly throughout said mass, the walls of said'chamber being perforated substantially throughout their entire area.
