ROTARY CAVITATION APPARATUS Russian patent published in 2001 - IPC

FIELD: devices for production of artificial cavitation in liquid media and use of cavitation effects for intensification of various physico-chemical processes. SUBSTANCE: apparatus has body forming a working chamber accommodating stator and rotor installed on shaft. Stator and rotor consist of discs. Rotor disc, first from apparatus inlet, has radial vanes located at an angle to its plane. The second rotor disc located between stator discs has radial blades whose front part is made in the form of wedge, and rear part, in the form of parallelepiped with radial grooves on its side faces. Stator discs have slots. Installed in slots of the second disc of stator is core triangular in cross-section. EFFECT: higher efficiency of activation of physico-mechanical processes, disinfection of sewage and fecal waters, decontamination of liquid radioactive wastes and production of heat energy. 4 cl, 2 dwg
