GENERATOR OF FIRE-EXTINGUISHING AEROSOL Russian patent published in 2013 - IPC A62C19/00 

FIELD: fire-prevention facilities.

SUBSTANCE: invention relates to fire-fighting equipment, in particular, to fire-extinguishing aerosol generators, containing combustion inhibitors, and is designed for volume extinguishing of fire in case of stationary installation in closed premises and equipment with an automatic start-up device controlled by fire alarm sensors. The fire-extinguishing aerosol generator comprises an axisymmetric igniter, a pyrotechnical explosive cartridge, a body, a jacket and a shell. The igniter is arranged on the open end of the pyrotechnical explosive cartridge, which is mounted in one of two body reservoirs of plate shape. Reservoirs of the body are oppositely joined by flanges and coated with heat-insulating layers. The central jacket and the shell form a reversible channel from a receiver to an output hole. The pyrotechnical explosive cartridge is pressed via a cardboard layer directly into one of reservoirs, flanges of which are connected without gaps. Inside the second reservoir on the bottom, where output holes are concentrically distributed, a shell is fixed, which covers the central jacket with a guaranteed gap and partial closure. The jacket is installed on the cross link, which limits a combustion chamber.

EFFECT: proposed technical solution provides for efficiency of fire extinguishing due to separation of burning hot particles of a liquid condensed phase of an aerosol, which is deposited in an adhesive manner inside a labyrinth output channel, which functions as a recuperator.
