ULTRASONIC ACTIVATOR Russian patent published in 1997 - IPC

FIELD: intensification of various processes. SUBSTANCE: ultrasonic activator has working intercommunicating chambers. First chamber carries inlet branch pipe, second chamber - outlet branch pipe. Each chamber houses stator and rotor put on shaft with holes arranged one opposite to other. Rotor presents working impeller of centrifugal pump which has ring across outlet with holes having width a equal to width a of hole of stator. Total area of holes of rotor equals total area of holes of stator and amounts to 0.1-0.7 area of inlet into proper working impeller. Hole pitch of rotor ring and hole pitch of stator are equal to 2.0-2.25 width a of these holes. Working chambers intercommunicate with the aid of diffusers coupling outlet of preceding impeller to inlet of following impeller. Outlet of last impeller is coupled with inlet of first impeller by means of diffuser fitted with throttle placed after outlet branch pipe. EFFECT: enhanced operational efficiency of ultrasonic activator. 6 cl, 7 dwg
