Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

[ EN ]

What is claimed is:

1 . A liquid treatment apparatus for processing a liquid, comprising:

an inlet nozzle including an orifice for directing a flow of liquid fluid through the orifice to define a fluid jet; and

a conical diffuser including a tip, a base portion, and a curved surface therebetween, wherein the conical diffuser is generally aligned with the orifice such that the fluid jet impacts upon the tip of the conical diffuser, and wherein the curvature of the curved surface is selected to maintain a substantially constant Froude number of the liquid along the conical diffuser.

2. The liquid treatment apparatus of claim 1 , wherein a profile of the conical diffuser, when viewed in cross section, is defined by a quarter of an ellipse.

3. The liquid treatment apparatus of claim 2, wherein the ellipse is defined by the following equations:


b =

r0xFr2

where a = the major radius of the ellipse

b = the minor radius of the ellipse

r0 = the radius of the orifice

Fr = the desired Froude number.

4. The liquid treatment apparatus of any of the preceding claims, wherein the inlet nozzle includes a curved inlet wall.

5. The liquid treatment apparatus of any of the preceding claims, wherein the base portion includes a rear wall on a side of the base portion opposite to the tip that is generally planar.

6. The liquid treatment apparatus of any of claims 1 -4, wherein the base portion includes a rear wall on a side of the base portion opposite to the tip that is generally curved, the curved rear wall having a substantially constant radius of curvature.

7. The liquid treatment apparatus of any of the preceding claims, further comprising a mounting plate to which the conical diffuser is mounted, the mounting plate including one or more apertures for allowing liquid to pass through the mounting plate.

8. The liquid treatment apparatus of any of the preceding claims, wherein the liquid treatment apparatus includes a plurality of inlet nozzles and a plurality of conical diffusers, each conical diffuser being generally aligned with a corresponding orifice of an inlet nozzle.

9. The liquid treatment apparatus of any of the preceding claims, wherein a surface of the liquid treatment apparatus is constructed of or coated with a material having a high surface energy for promoting a chemical reaction in the liquid fluid.

10. The liquid treatment apparatus of any of the preceding claims, wherein an electrical charge on a surface of the conical diffuser differs from an electrical charge on a surrounding surface of the liquid treatment apparatus.

1 1 . A system for processing a liquid, comprising:

a tank for holding a liquid medium;

a pump; and

a liquid treatment apparatus according to any of claims 1 -8, wherein the pump is configured to direct the liquid in the tank through the liquid treatment apparatus.

12. The system of claim 1 1 , further comprising a recirculation loop for directing liquid treated by the liquid treatment apparatus back to the tank.

13. A method of treating a liquid, comprising:

directing a flow of liquid through an orifice to define a fluid jet;

impacting the fluid jet upon a conical diffuser having a tip, a base portion, and a curved surface therebetween; and

maintaining a substantially constant Froude number as the liquid flows from the tip toward the base portion of the conical diffuser.

14. The method of claim 13, wherein maintaining a substantially constant Froude number further comprises selecting the curvature of the curved surface in order to maintain a substantially constant Froude number.

15. The method of claim 14, wherein selecting the curvature of the curved surface further comprises defining a profile of the conical diffuser, when viewed in cross section, to be a quarter of an ellipse.

16. The method of claim 15, wherein defining the profile of the conical diffuser further comprises defining the ellipse by the following equations:

a = ro x J-r

b =

a = the major radius of the ellipse

b = the minor radius of the ellipse

r0 = the radius of the orifice

Fr = the desired Froude number

17. The method of any of claims 13-16, further comprising:

(a) pumping a supply of liquid from a tank to the orifice;

(b) directing the liquid that has impacted the conical diffuser back to the tank; and

(c) repeating steps (a) and (b).
