ULTRASONIC SYSTEM FOR MIXING MULTIPHASE MEDIA AND LIQUIDS, AND ASSOCIATED METHOD

摘要

The invention describes an ultrasonic device primarily intended for sonication of liquid and multiphase-media (gas-liquid, solid-liquid) through flexural vibration of tuned blades. The ultrasonic system comprises a source of alternating electrical field, an electro-acoustic transducer connected to the source of alternating electrical field, a booster connected to the electro-acoustic transducer with a cross section distal to the electro-acoustic transducer smaller than a cross section proximal to the electro-acoustic transducer, and at least one tuned blade coupled to the booster, wherein the at least one blade couple flexural vibrations to the liquid or multiphasic media. The system allows the treatment of larger volumes of fluid media compared with conventional longitudinally resonant ultrasonic devices characterized by small radiating surfaces. The flexural motion of the tuned blades may be achieved through the use of an electro-acoustic transducer operated in a torsional mode of vibration, or via a sub-assembly excited in a torsional-longitudinal composite mode.
