NOZZLE FOR CREATING BUBBLES WITH A CIRCULAR FLOW Russian patent published in 2018 - IPC B01F3/04 B01F5/04 B05B1/02 B05B7/04 

FIELD: machine building.

SUBSTANCE: invention relates to a nozzle for creating bubbles with a circular flow, which creates bubbles (air bubbles), including small bubbles (nanobubbles and microbubbles). Nozzle 10 for creating bubbles with a circular flow includes tubular element 1, having a bottom, which has a circular cross-section, and tubular member 2, which is installed in element 1, having a bottom, from the other end of this element 1. Cylindrical space, enclosed inside element 1, having a bottom, and tubular member 2, serves as mixing chamber 6 for mixing gas and liquid with a circular flow. Tubular element 2 in the center has inlet 7, which is configured to flow liquid and gas into it, as well as first jet hole 8a and second jet hole 8b, which are designed to create a jet of liquid and gas. Inlet 7 is conically shaped with a gradual increase in diameter from first jet hole 8a to create a jet to stirring chamber 6 and mix the gas and the liquid with a circular flow. In the region of that end of inlet 7, which faces mixing chamber 6 of gas and liquid mixing with a circular flow, plurality of notches 7a are formed.

EFFECT: invention provides higher efficiency of creating bubbles in comparison with ordinary nozzles, without reducing this efficiency even when using a fluid containing impurities.
