Description of the development:
()
For the treatment of liquid media, the installation uses physical processes accompanying the phenomenon of ultrasonic cavitation, in which vapor-gas cavitation bubbles are formed in the liquid in the rarefaction phase of the ultrasonic wave, which collapse in the compression phase. To create a region in a liquid with developed cavitation, the principle of focusing ultrasonic vibrations to a high level of intensity in the region of the longitudinal axis of a tubular resonator excited on the main mode of radial oscillations was used. To excite the resonator of radial oscillations, piezoelectric half-wave drives of axial displacements with knife-shaped oscillatory speed transformers are installed on its outer surface. Inactivation of microorganisms in the cavitation environment occurs due to: - mechanical destruction of microorganisms by spherical shock waves and cumulative jets formed during the collapse of cavitation bubbles; - local pressure increase up to 1000 MPa and temperature up to 1000 ° С at the collapse of cavitation bubbles; - intensification of oxidative processes in the cavitation region.
