FIELD: dispersing acoustic technique used in coal mining, food making, machine engineering and other branches of industry. SUBSTANCE: double chamber vortex generator includes inlet and outlet ducts, vortex chamber and additional second vortex chamber and additional duct between both chambers. Ducts are made according to conditions 2πR, where d1 - diameter of inlet duct, d2 - diameter of additional duct, d3 - diameter of outlet duct. Radius R of vortex chamber and length L of additional duct are determined by next relation: 2 = R=L. EFFECT: enhanced intensity of generated irradiation, realization of matched flowing mode in ducts and chambers. 3 cl, 1 dwg
