Patent ID: 7086777

Claim:
A device for creating hydrodynamic cavitation in fluids comprising: a flow-through chamber defined by at least one wall; at least two baffles disposed within the flow-through chamber and spaced from said at least one wall, the at least two baffles includes a first baffle and a second baffle disposed downstream from said first baffle, said first baffle configured to generate a, first hydrodynamic cavitation field downstream therefrom, said first baffle capable of being moved axially within said flow-through chamber during operation of said device to vary the effect of the first hydrodynamic cavitation field generated downstream from said first baffle, said second baffle configured to generate a second hydrodynamic cavitation field downstream therefrom, said second baffle capable of being moved axially within said flow-through chamber during operation of said device to vary the effect of the second hydrodynamic cavitation field generated downstream from said second baffle, and wherein the largest diameter of said second baffle is greater than the largest diameter of said first baffle, wherein at least one of said first and second baffles includes a tapered body, the tapered body includes an upstream end and a downstream end having a greater cross-sectional area than the upstream end, and wherein said first and second baffles are independently movable with respect to each other.
