Abstract
An aqueous stream is pumped through a vortex cylinder. The aqueous stream is rotated in a downwardly moving spiral stream within the vortex cylinder at a high downward velocity. The downward velocity of the aqueous stream increases as it flows through a discharge conduit concentrically located within a mixing chamber of the vortex cylinder. An adjustable inlet tube open to atmospheric pressure extends through the vortex chamber and into the discharge conduit. A negative pressure zone is created at the discharge end of the discharge conduit for drawing fluid into the aqueous stream for mixing therewith and dissolving oxygen in the aqueous solution.
Claims4
An apparatus for aerating an aqueous solution, comprising:
- a) a vortex cylinder operatively connected to a pump, said vortex cylinder including a vortex chamber and a mixing chamber, wherein said mixing chamber includes an open lower end;
- b) a transverse wall separating said vortex chamber from said mixing chamber, said transverse wall including a centrally located opening providing fluid communication between said vortex chamber and said mixing chamber;
- c) a discharge conduit concentrically disposed within said mixing chamber, wherein said discharge conduit extends downwardly from said wall and includes an upper end circumscribing said opening;
- d) an air intake tube concentrically disposed within said vortex cylinder, said air intake tube including an upper portion extending through a top wall of said vortex cylinder, said upper portion of said air intake tube including an externally threaded section engaging a threaded collar mounted on said top wall of said vortex cylinder, and wherein a lower portion of said air intake tube extends into said discharge conduit and terminates at a point spaced above a lower end of said discharge conduit;
- e) a valve assembly having an axially extending air intake passageway connected to said air intake tube;
- and
- f) an inlet port proximate an upper end of said mixing chamber, said inlet port providing fluid access to said mixing chamber.
