UNIT FOR AERATING FLUIDS Russian patent published in 1994 - IPC

FIELD: aerating fluids. SUBSTANCE: gas-jet units 21 for emitting acoustic and ultrasonic waves have nozzles 10 positioned around holes 10 and cavities 22 mounted in flat lattices 9, each nozzle 20 and corresponding cavity 22 being in a coaxial relation to each other. Compressed air is fed through nozzles 20 of emitters 2 to strike cavities 2 with the result that acoustic and ultrasonic waves are generated. EFFECT: higher efficiency of dispersing air in liquid and in flotation pulp due to increased acoustic effect and frequent gas-and liquid contact to achieve dispersal, enhanced purifying of liquids through flotation. 4 dwg
