FIRE EXTINGUISHING FLUID FIRE EXTINGUISHING MODULE Russian patent published in 2017 - IPC A62C35/00 

FIELD: fire safety.

SUBSTANCE: invention relates to field of fire extinguishing, in particular, to modular device for fires and ignitions isolation and extinguishing in class A and B buildings. Fine atomized extinguishing fluid fire extinguishing module comprises sealed housing, filled with fire extinguishing fluid with provision of free space above its level. In housing upper part gas generator is arranged, coaxially arranged in barrel. Between walls of gas generator and barrel cavity is formed with provision of interaction between it and space above fluid level in housing. In module housing lower part cylindrically shape release nozzle is mounted, provided with rupture disc. For fluid fine spraying sprayer is installed, which is made in form of hollow body, installed directly on outlet nozzle making its bottom part, where paired channels are made uniformly in annular rows with provision of each pair of channels axes intersection between each other outside of sprayer at distance of 5–8 mm from sprayer outer surface, paired channels rows are made, at least, at two levels in sprayer height, bisectors of angles between lower level paired channels are oriented relative to sprayer axis at angle of 20–35 degrees, and of upper level are at angle of 45–70 degrees, in direction of protected surface. Ratio of sprayer channel length and channel diameter makes 1:0.2–0.5.

EFFECT: when using module provided is uniform distribution of fire extinguishing fluid over entire surface of protected object with absence of “dead” zones.
