摘要：
The subject invention refers to the field of cavitation treatment of liquid medium as well as the medium having the density of water or other liquid phase exceeds 65-70% of total mass.Method of ultrasonic cavitation treatment of liquid medium is what the mode of acoustic cavitation is being simultaneously generated on two or several different frequencies, at that the mechanical vibration system - channel with rectangular cross-section, is made in the form of tandem membranes having different frequencies of fundamental harmonic of vibrations, generating of acoustic vibrations with formation of standing wave is performed in phase over against the channel, that in turn generate quasi-plane standing waves, corresponding with vibrations frequencies of the membranes, in the channel clearance, here the channel clearance h is taken divisible by quarter-wavelength, exited in this treated liquid mediumefor the applied frequencies:wherefi- frequencies of fundamental harmonic of standing wave of the channel membranes, HzC - acoustic velocity in the liquid mediume, mpsh - channel clearance, mit is required the vibration amplitude of channel boarder is to be fitted optimum for different stages of treatment of liquid medium and exceeds a threshold of acoustic cavitation.This method allows to upgrade the power and amplitude of acoustic wave, coherence) cavitation influence to the treated liquid medium and the bodies place in this medium with the simultaneous limitation of power of ultrasonic sources.
