ALL-PURPOSE AEROHYDRODYNAMIC NOZZLE Russian patent published in 2011 - IPC B05B7/08 

FIELD: process engineering.

SUBSTANCE: proposed device may be used in industry (furnace injectors, ICE injectors, etc) and health protection cleaning air of dust, air humidification and saturation by medical preparation vapors, etc). Invention aims at developing structure for producing gas-fluid finely dispersed and homogeneous mixes in operation in gas and fluid media. For this, proposed nozzle comprises central channel for gas forced feed with its axis aligned with that of central body, and peripheral annular fluid feed channel formed by fluid feed tube inner wall and central body surface. Fluid feed annular channel terminates in circular convergent tapered nozzle. Nozzle slit-like channel axis and gas feed channel axial line forms angle a varying from 10°<α≤90°. Nozzle outlet cross section embraces gas feed channel outlet section.

EFFECT: homogeneous finely-dispersed gas-fluid mix and retention of almost 100% of fed gas in fluid medium for long time.
