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 assembly operatively connected to a pump;
- b) a vortex member defining a vortex chamber, wherein said vortex member is mounted in vertical alignment above a housing for an aerated aqueous solution;
- c) a concave wall separating said vortex chamber from said housing, said wall including a centrally located opening providing fluid communication between said vortex chamber and said housing;
- d) a discharge conduit concentrically disposed within said housing, wherein said discharge conduit depends from said wall and includes an upper end circumscribing said opening;
- e) a concentrically disposed air intake tube having an upper portion extending through said vortex chamber and a lower portion extending into said discharge conduit, wherein a lower end of said air intake tube is spaced above a lower end of said discharge conduit;
- f) a mixing tube concentrically disposed within said housing having an upper end extending through the upper end of said housing;
- and
- g) a port proximate an upper end of said housing, said port providing fluid access to said housing.
