Abstract:
1. Ultrasound reactor comprising: a) a reactor body; b) a reactor tube disposed within said reactor body; and c) a magnetostrictor transducer comprising at least one annular element positioned coaxial with an internal wall of said tube, and mounted on the external wall of said tube, wherein said transducer mounted on said tube in such a way so as to transmit ultrasonic radiation to the interior of said tube and to induce an upwardly flowing cavitation stream whose longitudinal axis substantially coincides with a longitudinal axis of said tube, wherein the diameter of said tube is proportional to the wavelength of said transmitted ultrasonic radiation, characterized in that the reactor further comprises d) a cylindrical absorber mounted on the outer periphery of said annular element, wherein a selected tube diameter is suitable for inducing waves of said ultrasonic radiation to propagate at a resonance frequency such that the efficiency of the reactor without an absorber ranges fro 30 to 40% and the efficiency of the reactor ranges from 60 to 80% when said absorber is mounted on each said annular element.
