REDUCING NOZZLE FOR WATER UNDER PRESSURE FOR GENERATING MICRO BUBBLES IN FLOTATION PLANT Russian patent published in 2008 - IPC B01F5/06 

FIELD: mechanic.

SUBSTANCE: nozzle contains primary pressure reduction stage, an intermediate chamber, secondary pressure reduction stage, and outlet tube. The pressure reduction stages are designed as diaphragms with holes; the first stage absorbs 5-20% of the available pressure, the second stage reduces the water pressure from the saturation pressure to the outlet nozzle pressure; the intermediate chamber absorbs 5-30% of the available pressure. The outlet tube widens quickly and provides reduction of cavitation.

EFFECT: provides micro bubble generation mode not destroying floccules at nozzle outlet at high flotation plant capacity.
