摘要

FIELD: apparatuses for sprinkling cooled water in ventilation type cooling towers of water supply circulating systems in electric power stations and industrial plants. SUBSTANCE: apparatus includes inlet branch pipe on which holder with rod is fixed. In upper portion of rod cone-like helical nozzle is mounted. Said nozzle is made of flat belt whose edges are arranged along Archimedian helix. Helical belt of nozzle may have whose surfaces bent upwards or downwards to branch pipe. EFFECT: enhanced efficiency of sprinkling at small pressure of water, elimination of clogging of sprinkling apparatuses with impurities brought by water. 3 cl, 4 dwg
