WIDE-FLARE SWIRL-TYPE SPRAYER Russian patent published in 2012 - IPC B05B1/34 

FIELD: process engineering.

SUBSTANCE: invention relates to sprayers of fluids and solutions. Proposed sprayer has casing with inlet branch pipe, inlet cylindrical chamber aligned therewith and swirling chamber. Said swirling chamber is aligned with inlet chamber and represents a cylindrical barrel. The latter has, at least, three tangential bores made on its lateral surface. Axes of said bores are arranged along tangential line to swirled chamber, that, is there is a multichannel tangential inlet. Nozzle insert is arranged aligned with swirling chamber. Said insert houses three coaxial calibrated holes arranged aligned with cylindrical surface of swirling chamber: taper hole with diameter equal to truncated cone lower base, cylindrical hole and shaped hole consisting of cylindrical section and chambered round inlet. Insert cylindrical hole diameter equals that of taper hole truncated cone upper bas and to that of shaped hole cylindrical section.

EFFECT: higher efficiency of spraying.
