ULTRASONIC SPRAYER OF LIQUID Russian patent published in 2009 - IPC B05B17/06 

FIELD: technological processes.

SUBSTANCE: invention is related to devices for spraying of liquids, in particular water and aqueous solutions used in extinguishing of fires in closed rooms, may be used for a whole range of production processes. Technical result is achieved by the fact that nozzle is made in the form of deflector shaped as axisymmetric figure with cylindrical side surface and internal hollow truncated cone. Nozzle deflector is installed in body coaxially to central gas flue and is inverted with a large base of hollow truncated cone opposite to central gas flue with creation of nozzle slot. Height of resonator groove and width of nozzle slot are selected provided that 1.7≤σ/δ≤2.2. Sprayer is also equipped with an annular resonator with cut edge in the form of conical surface. Annular resonator is installed on bearing part of body with creation of grooves relative to upper part of resonator. Upper part of body is arranged with a cone-shaped funnel coupled with cut edge of resonator.

EFFECT: increased efficiency, higher intensity of impact waves and reduction of size of produced finely dispersed liquid drops.
