FIELD: process engineering. ^ SUBSTANCE: invention relates to generators of acoustic vibrations in fluid flows and may be used for intensification of physicomechanical, hydromechanical and heat-and-mass exchange processes in systems "liquid-liquid" and "solid-liquid". Rotor-type apparatus comprises casing with intake and discharge branch pipes to accommodate rotor and stator with channels in cylinder lateral walls arranged concentrically, and insonify chamber. Convergent-divergent nozzle is arranged inside inlet branch pipe to reciprocate therein. Tapered cylindrical insert is fitted into divergent section to make annular convergent tapered cylindrical slotted nozzle. Hollow cylinder is arranged on rotor inner face surface, opposite said slotted nozzle, said cylinder being cut along generating lines to form cantilever plates. Said plates feature different principal base frequency of oscillations defined from enclosed relationship. Plate ends are sharpened. At plates identical thickness, their length is defined by relationship. ^ EFFECT: intensified cavitation in rotor chamber. ^ 4 cl, 5 dwg |
