METHOD FOR SIMULTANEOUS CAVITATION TREATMENT OF LIQUID MEDIA VARYING IN COMPOSITION

摘要

The invention relates to the field of simultaneous cavitation treatment of liquid media varying in composition. An acoustic cavitation mode is formed owing to a twin resonant effect within a continuous-flow mechanical vibrating channel system with a rectangular cross section having a finite length, with acoustic vibrations being generated inphase on opposite sides thereof. Additional continuous-flow channels for supplying the liquid media to be treated are arranged in a clearance of the channel containing working liquid, the specific acoustic resistance of the material of which additional channels is close to the acoustic resistance of the working liquid. The width of the clearance h is selected to be a multiple of one quarter of the wavelength for the working liquid at a frequency equal to the fundamental harmonic of the vibrations of the wall of the channel system. The method makes it possible, with the aid of a single continuous-flow reactor, to treat various media without mixing said media, which is convenient in processing cycles with simultaneous production of a wide range of products and for rapidly restructuring production from manufacturing one type of product to manufacturing another.
