DISPERSION NOZZLE, FLOTATION MACHINE EQUIPPED THEREWITH AND METHOD FOR OPERATING SAME Russian patent published in 2016 - IPC B03D1/24 B03D1/02 B01F5/04 B01F3/04 

FIELD: gas industry.

SUBSTANCE: invention relates to a dispersion nozzle for dispersing a liquid and a floatation plant. Dispersion nozzle for liquid dispersion, in particular a suspension, also having at least one gas, comprises a gas feed nozzle and a tubular mixing arrangement, which has a combined inlet zone for at least one gas and liquid and an outlet zone for a gas/liquid mixture formed from at least one gas and liquid. Mixing arrangement adjoins gas feed nozzle. Gas feed nozzle is tapered in direction of mixing arrangement and opens into inlet zone. Mixing arrangement in inlet zone has at least number N≥3 of suction holes for liquid. Suction holes are arranged perpendicular or at an angle to longitudinal central axis of dispersing injector. Ratio of a diameter D_G of a gas outlet opening of gas feed nozzle and internal diameter D_M of mixing arrangement is in range from 1:3 to 1:5. Gas-intake nozzle is equipped with at least one gas regulating valve for metering amount of at least one gas fed into liquid. During operation of dispersion nozzle, gas supply through gas-intake nozzle is performed so that, at least one gas on tas outlet opening of gas-intake nozzle has density of pulse current in range from 5·10³ to 5·10⁴ kg/(m·s²).

EFFECT: technical result is increased dispersion of suspension and gas.
