Abstract
A method and apparatus for treating fluids by transmitting ultrasonic energy into the fluids to produce high intensity cavitations in the fluids as the fluids pass through the apparatus. The fluids are retained in the apparatus for a sufficient period of time to destroy contaminates in the fluids, neutralize acids or bases in the fluids and dissociate other chemical compounds.
Claims9
An apparatus for treating fluids, then apparatus comprising:
- a) a central passageway having an inner surface and a central axis for containing a fluid;
- b) a radial ultrasonic transducer being positioned to transmit ultrasonic energy into the central passageway toward the central axis;
- c) a tube adapted to reflect back the transmitted ultrasonic energy and having a cylindrical outer surface and coaxially and centrally positioned in the central passageway, the outer surface of the tube being positioned at a distance from the inner surface of the central passageway which is not a multiple of a wave length of the transmitted ultrasonic energy to reflect back an energy into the central passageway from the outer surface of the tube toward the inner surface of the central passageway at an intensity greater than that of the transmitted energy;
- d) a fluid inlet to the passageway;
- and
- e) a fluid outlet from the passageway.
