CASCADE NOZZLE Russian patent published in 2005 - IPC

FIELD: heat-and-power engineering, particularly for medium and deep water spraying in cooling towers, scrubbers, gas and steam condensing plants, gas-cleaning systems, for spraying high-viscous liquids or liquids with considerable content of impurities.

SUBSTANCE: nozzle comprises connection pipe and deflecting members formed so that cone angle of each next deflecting member is less than that of previous one. Nozzle has conical body. Deflecting members made as deflecting washers are arranged along vertical axis between at least two fixing posts. Deflecting washers have inner orifices decreasing in direction away from inlet connection pipe. Each deflecting washer is made as truncated cone. Outermost deflecting washer is of hemispheric shape and adapted for water spraying into area located under nozzle connected with pipeline by straight and adapter couplings. To increase hydraulic capacity and system flexibility cascade nozzles with lesser inlet connection pipe diameters are substituted for ones with greater diameters.

EFFECT: increased cooling efficiency, simplified structure, improved flexibility, minimizing of nozzle clogging.
