ULTRASONIC FLOW-TYPE DISPERSER Russian patent published in 2004 - IPC

FIELD: ultrasonic dispersers for homogenization of heavy fuels, liquid mixtures or milk, water-and-fuel emulsions; decontamination of potable water and pasteurization of juices; manufacture of paints, lubricants and various emulsions for chemical and food- processing industries. SUBSTANCE: proposed device has piezo-transducers with cover plates made integral with concentrators at varying inner sections; concentrators are provided with axial holes. Secured acoustically rigidly and detachably on outlet end faces of concentrators are resonance membranes with flow-through holes. Formed on either side of resonance membranes are slotted clearances due to acoustic transparence diaphragms and circular clearances. Device may be provided with focusing systems, cavitation activators, half- wave probes, half-wave resonators and additional high-frequency radiators. EFFECT: improved quality of cavitation treatment of materials. 9 cl, 7 dwg
