HYDRODYNAMIC CAVITATION APPARATUS Russian patent published in 2000 - IPC

FIELD: liquid flow processing. SUBSTANCE: apparatus is made in form of tube provided with end face cover-flow accelerator at inlet hole, cylindrical chamber - flow divider, chamber-jacket, flow intake, cavitation insert- nozzle enclosed in contraction chamber made in form of ring channel, and chamber-damper. Flow of liquid delivered through channels in end face cover is divided in cylindrical chamber by rotation into peripheral heated flow and axial colder flow. Peripheral flow passes into inner part of cavitation insert-nozzle through flow intake. Axial flow gets into chamber-jacket through channels in end face cover, and passes from chamber-jacket into contraction chamber through radial channels. Cavitation results from mixing of two flows at nozzle outlet and kinetic energy accumulated at movement turns into heat energy, thus heating the liquid. Apparatus provides stabilization of cavitation characteristics, increased intensity of process owing to increase in number of cavitation generating points and obtaining of energy intensive liquid flow. EFFECT: simplified control of apparatus, provision of energy intensive liquid flows, including water.
