LONG-RANGE GAS-DROP JET GENERATOR Russian patent published in 2011 - IPC B05B7/00 

FIELD: process engineering.

SUBSTANCE: invention relates to gas-drop jet generation and may be used in fire fighting, agriculture, etc. Fluid feed comprises forcing fluid axially via feed branch pipe, confuser and cylindrical nozzle. Tangential feed of fluid is performed via tapered cylinder-shaped cartridge aligned with cylindrical nozzle. Vortex annular chamber with fluid feed branch pipe is secured on cartridge cylindrical part. Two lines of fluid feed tangential channels are made along edges of said annular chamber. At least three tangential channels are arranged in every said line to communicate annular chamber with housing cylindrical chamber. Central solid stream-lined drop-like body is arranged in housing tapered section to increase two-phase flow speed and features low hydraulic drag. Said stream-lined body is secured to housing tapered section chamber inner surface by at least three rods. Gas feed system comprises turbo compressor, annular coaxial fluid feed inlet and mixing chamber formed by housing cylindrical inner space accommodating lines of fluid feed tangential channels.

EFFECT: higher efficiency of fire fighting.
