FIRE-EXTINGUISHING AEROSOL GENERATOR OF OPERATIONAL APPLICATION Russian patent published in 2018 - IPC A62C19/00 

FIELD: fire safety.

SUBSTANCE: invention relates to hand-held mobile devices for operational extinguishing fires by generation of aerosol containing active fire retardance agents, and can be used as propellant in fire at the incipient stage for primary fire suppression in closed volumes, especially in conditions of high humidity, on ships, in port facilities, warehouses, etc. Fire-extinguishing aerosol generator of operational application is made of two counter-bonded threaded fasteners along the flanges of the case tanks of a disc shape, where through thermal barrier made from hardening material placed functional checkers of pyrotechnic composition with a gap between the end combusting surfaces formed by Sam Browne studs of their flanges, forming a disc exit nozzle, and to which a case of ignition device is radially adjacent, fixed to a profile handle mounted between the flanges of the body containers, the spring-load tip of cap primer is locked with safety pin. According to the invention, combustion surface of pyrotechnic checkers is lacquered or cover with silicone, passage section of the disk nozzle is regulated by means of a set of measuring orifices of fasteners placed between the Sam Browne studs of the flanges, while the thermal barrier is made of foamed concrete or flooring cement, and the tip is spring-loaded to the end of the case, opposite to the cap primer.

EFFECT: proposed technical solution increased the functional reliability of the propelling generator of simpler and more technologically advanced design with an adjustable output of extinguish mixture, used for operational primary suppression of foci of fires at the incipient stage in a closed volume, mainly in conditions of high humidity.
