CAVITATION REACTOR Russian patent published in 2009 - IPC B01J19/10 

FIELD: chemistry.

SUBSTANCE: invention relates to apparatus for carrying out physico-chemical processes in a liquid using energy of elastic harmonic oscillations propagated by more than two ultrasonic sources at the same frequency, and can be used in acoustochemistry, as well as in analysis and practical use of sonoluminescence and sonosynthesis. The reactor has coaxially placed acoustic resonators, which form plane-elastic waves with circular fronts in liquid. Dimensions of resonators are chosen based on the relationship between the diametre clearance between waveguides of resonators, and phase of each even resonator is shifted by half the wave period relative the phase of each odd resonator. Instantaneous value of sound pressure of cavitation noise from all resonators at the centre of the resonator at any point in time is approximately in the same phase. Also the centre of the reactor is the location of maximum amplitude of sound pressure from cavitation of each resonator.

EFFECT: intensification of processes due to increase of total amplitude of sound pressure and easier control of the reactor.
