FIRE FIGHTING METHOD USING GAS-LIQUID MIXTURE Russian patent published in 2010 - IPC A62C35/00 B05B7/10 

FIELD: medicine, fire-fighting equipment.

SUBSTANCE: to improve rapidity of action of fire fighting using a gas-liquid mixture, the latter is obtained in a device forming a gas-liquid mixture of vortex type which is equipped with a vessel with fire extinguisher, and which is connected to the starting container with a working gas. The vessel with fire extinguisher is fastened to the premise building structure and equipped with a device of emission of gas phase combined with the measuring tracer for fire extinguisher. Device for formation of gas-liquid mixture of vortex type is made in the form of a conical mixing chamber with tangential inlet of gas in the upper part connected through a flexible high pressure hose of working gas such as nitrogen or CO₂ to the vessel - launcher cylinder with working gas. Gas is put to the chamber through coaxial to it conical perforated spiral with coefficient of perforation 50÷80%, and liquid-gas mixture is flown into the central pipe then into the distribution grid is carried out from the bottom part of the camera connected to device of extinguishing agent discharge combined with a safety valve, at that a vertical chamber pipe is connected through a tee to device of fire extinguisher inlet and pressure indicator. Each irrigator or block of irrigators of the distribution grid is supplied with device of orientation in one or two planes.

EFFECT: improvement of rapidity of action of fire fighting.
