Abstract (en)

[origin: WO2005123264A1] A liquid atomizer comprises a housing (12), a centrifugal liquid stream swirl unit, and a nozzle (17) with a profiled channel. The centrifugal swirl unit is configured as a hollow cylindrical insert (16) with an inlet axial channel (21) and tangentially oriented inlet channels (22) provided in the side wall of the insert (16). The cross-sectional sizes of the inlet channels of the centrifugal swirl unit are selected on the condition that: 4Sa<= St<= 6Sa, where St is a total cross-sectional area of the tangentially oriented channels (22), Sa is a cross-sectional area of the axial channel (21). A fire-extinguisher comprises a reservoir filled with a fire-extinguishing liquid, a system for replacing the liquid from the reservoir and a liquid atomizer including a centrifugal liquid stream swirl unit and a nozzle (17). During operation, a high-velocity gas-droplet jet is generated with droplets of uniform size and a stable spray cone angle.
