SWIRLING NOZZLE Russian patent published in 2013 - IPC B05B1/34 

FIELD: process engineering.

SUBSTANCE: invention relates to heat-and-power engineering and may be used in coolers, scrubbers and other heat exchange hardware that sprays fluids and ejects gases. Nozzle comprises distribution chamber with orifice, adapter with outlet and fluted swirler. Flutes on outer surfaces diverge from axis to periphery and smoothly flex to change into converging channels to communicate with complex-shape inner chamber and to change into blind cylindrical hole. Chamber top section features cylindrical shape while mid section is shaped to convex parabolic surface. Converging channels are directed along tangent toward swirler inner chamber without through bore along its axis. Adapter outlet is shaped to Venturi nozzle. Hemispherical ledges are arranged at nozzle confuser section and inner chamber convex parabolic section. Simultaneously, notable rarefaction is created inside swiftly swirling vortex to cause intensive fluid evaporation and to force the cone outward saturated with vapours that facilitates fluid cooling.

EFFECT: higher ejection capacity.
