Claims
- 1. A cyclone aerator, comprising:
- a substantially longitudinally oriented, hollow vessel having a substantially cylindrical configuration;
- plates longitudinally positioned within said hollow vessel to extend in a spaced relationship to the hollow vessel to form a peripheral space, said plates extending partially towards a center of said hollow vessel to firm a substantially cylindrical central void, said plates positioned adjacent to and spaced from one another and positioned in said hollow vessel in a non-radial orientation;
- an inlet proximate an upper end of said hollow vessel for introducing a fluid suspension into said central void in a generally tangential fashion to create a circular flow in said central void;
- a gas inlet in said hollow vessel to introduce a gas into said peripheral space wherein said gas flows through said plates to admix with said fluid suspension; and
- an outlet proximate a lower end of said hollow vessel for purging said fluid suspension and said gas admixed with said fluid suspension.
- 2. The cyclone aerator of claim 1 further including a solid-walled cylinder positioned proximate a center of said central void.
- 3. The cyclone aerator of claim 1 further including a porous hollow cylinder positioned proximate a center of said central void, said porous hollow cylinder having a central void; and a second gas inlet to introduce a second gas into said hollow cylinder central void wherein said second gas travels through said porous hollow cylinder to admix with said fluid suspension.
- 4. The cyclone aerator of claim 3 wherein said porous hollow cylinder comprises a material selected from the group consisting of porous stainless steel, ceramic material, and polyethylene.
- 5. The cyclone aerator of claim 3 wherein said porous hollow cylinder includes pores sizes between about 5 and 250 microns.
- 6. The cyclone aerator of claim 1, further comprising a gas source providing an oxidant gas, said gas source removably connected to said gas inlet.
- 7. The cyclone aerator of claim 6 wherein said oxidant gas comprises ozone.
- 8. The cyclone aerator of claim 1 wherein the number of plates is determined by the equation:
- N=C/((T/(2*cos .alpha.))+G)
- wherein N is the number of plates, T is the thickness of each of said plates, .alpha. is an angle between a radial line from a center of said hollow vessel and a planar position of each of said plates, G is the gap between any two of said plates, and C is the quantity 2*.pi.*R2 wherein R2 is the desired radius from a center point of said hollow vessel to an external edge of said plates and is determined by the equation:
- R2=(Lp*sin.alpha.*(L-1))/(Lp*sin.alpha.-L*tan.alpha.)
- wherein Lp is the plate width, L is the difference between the distance between a center point of said cylindrically shaped chamber to an external edge of any of said plates and the radius of said hollow vessel, and .alpha. is an angle between a radial line from said center of said hollow vessel and said planar position of each of said plates.
- 9. A cyclone aerator, comprising:
- a jacket tube, said jacket tube defining an interior space;
- a top cover removably attached to said jacket tube, said top cover including a plurality of top flanges;
- a bottom cover removably attached to said jacket tube, said bottom cover including a plurality of bottom flanges, said plurality of bottom flanges correspondingly aligned with said plurality of top flanges;
- a plurality of removable plates oriented within said interior space of said jacket tube, each of said plurality of plates in orientation with at least one of said plurality of top flanges and at least one of said correspondingly aligned bottom flanges;
- a gas inlet in communication with said jacket tube whereby a gas may be introduced into at least a portion of said interior space of said jacket tube;
- a fluidized suspension feed inlet in communication with said jacket tube including means to create a swirling flow pattern in said fluidized suspension whereby said fluidized suspension may be introduced into at least a portion of said interior space of said jacket tube; and
- a discharge outlet in communication with said jacket tube whereby said gas and said fluidized suspension may be purged from at least a portion of said interior space of said jacket tube.
- 10. The cyclone aerator of claim 9 wherein said plurality of removable plates extend from an internal edge of each of said plurality of plates towards said jacket tube from a central position in said interior space to extend in a non-radial fashion to an external edge of said plurality of plates whereby said plurality of plates are at an angle to one another.
- 11. The cyclone aerator of claim 9 wherein said feed inlet is proximate said top cover.
- 12. The cyclone aerator of claim 9 wherein said feed inlet is an integral portion of said top cover.
- 13. The cyclone aerator of claim 9 wherein said discharge outlet is proximate said bottom cover.
- 14. The cyclone aerator of claim 9 wherein said discharge outlet is an integral portion of said bottom cover.
- 15. A cyclone aerator, comprising:
- a substantially longitudinally oriented jacketing tube, said jacketing tube having a first open end and a second open end at opposing ends of said jacketing tube;
- a top removably connected to said first open end of said jacketing tube, said top including top flanges;
- a bottom removably connected to said second open end of said jacketing tube, said bottom including bottom flanges, wherein said bottom flanges are substantially aligned with said top flanges;
- a plurality of plates, said plurality of plates longitudinally disposed within said jacketing tube, each of said plurality of plates substantially rectangular in shape having an internal edge and an external edge, each of said plurality of plates extending in a non-radial manner from said internal edge disposed proximate a longitudinal centerline of said jacketing tube to said external edge disposed proximate said jacketing tube, said internal edges of said plurality of plates defining a substantially cylindrical central chamber oriented around said longitudinal centerline of said jacketing tube, said external edges of said plurality of plates and said jacketing tube defining an outer chamber;
- a feed inlet, said feed inlet proximate said top whereby a fluidized suspension may be introduced into said substantially cylindrical central chamber of said jacketing tube in a tangential fashion about said longitudinal centerline of said jacketing tube;
- a gas inlet, said gas inlet proximate a midpoint of said jacketing tube whereby a gas may be introduced into said outer chamber, said gas passing between said plurality of plates to said central chamber; and
- an outlet, said outlet located proximate said bottom, said outlet in communication with said central chamber whereby said fluidized suspension and said gas exit said central chamber.
