SWIRL ATOMISER Russian patent published in 2013 - IPC B05B1/34 F23D11/04 

FIELD: process engineering.

SUBSTANCE: invention relates to fluid and solution sprayers. Swirl atomiser comprises case made up of feed union with central bore and nozzle. Said case is rigidly jointed with coaxial cylindrical sleeve with outer thread. Atomiser composed of centrifugal fluid swirler fitted to case lower part composed of cylindrical insert with, at least, three tangential inlet cylindrical holes. Note that said sleeve makes nozzle integral part aligned with radial-flow swirler that has cylindrical throttle bore made in its face surface. Radial-flow swirler is arranged in case cylindrical chamber to form annular cylindrical chamber to feed fluid to radial-flow swirler tangential fluid inlets and communicated with outlet diffuser chamber. Said tangential fluid inlets represent channels arranged tangentially to cylindrical insert inner surface. Conical cowl is made at centrifugal swirler end surface.

EFFECT: higher efficiency due to increased spray cone.
