RADIAL-FLOW VORTEX NOZZLE Russian patent published in 2013 - IPC B05B1/34 F23D11/04 

FIELD: process engineering.

SUBSTANCE: invention relates to fluid and solution sprayers. Nozzle comprises case with swirling chamber and atomiser. Case is composed of union with fluid feed hole and coaxial cylindrical sleeve rigidly jointed thereto. Centrifugal swirler composed of blind cylindrical insert is connected to case lower section and aligned therewith. Insert has at least three tangential inlet cylindrical bores. Radial-flow swirler has communicated and aligned axial, taper and cylindrical throttling bores. 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 two chambers: conical and cylindrical chambers aligned with said swirler. Chambers are arranged so that outlet of one chamber makes inlet for another chamber. Said tangential fluid inlets represent channels arranged tangentially to cylindrical insert inner surface. Swirling intensifier with inner helical thread is rigidly secured to cylindrical chamber edge and aligned therewith.

EFFECT: higher efficiency due to increased spray cone.
