ULTRASOUND OSCILLATING SYSTEM Russian patent published in 2013 - IPC B06B1/06 

FIELD: process engineering.

SUBSTANCE: invention relates to ultrasound hardware, particularly, to device intended for intensification of processes in fluid homogeneous heterogeneous media by ultrasound wideband oscillations of cavitation spectrum and may be used for acceleration of dispersion, homogenisation, extraction, separation, etc. Ultrasound oscillating system incorporates cylindrical shell with stopped end face jointed to the case and furnished with inlet and outlet branch pipes. Shell wall thickness is many times smaller than half the ultrasound oscillation wavelength and is arranged coaxially with ultrasound radiator. Shell is filled with fluid and arranged relative to said radiator so that the distance between radiator surface and shell inner surface makes one fourth of wavelength of ultrasound oscillation in fluid between radiator and shell. Gas-vapor bubbles originate and instantly collapse in fluid between radiator and shell at ultrasound oscillations in "developed cavitation" conditions. Collapsing gas-vapor cavities make the source of wide frequency band. Combination of ultrasound frequency oscillations and wideband oscillations of cavitation origin make the source of wide spectrum oscillations.

EFFECT: intensive fluid cavitationless processing in fluids in wide frequency range.
