PLANT FOR AUTOMATIC FIRE EXTINGUISHING Russian patent published in 2019 - IPC A62C13/22 

FIELD: fire safety.

SUBSTANCE: invention relates to the field of fire extinguishing, in particular, to stationary facilities, the action of which is based on use as combustion inhibitors of suspended highly dispersed solid particles in a gas carrier – aerosol, formed during burning of pyrotechnic block and directed into protected volume, where it suppresses fire center. Plant for automatic fire extinguishing in composition of quenching mixture output cooler, including distributed baffle plates and gas permeable frames, and an aerosol generation device comprising a housing coupled with the receiver, a pyrotechnic cartridge carrying the igniter, the igniter of which is connected to the external trigger, and the enclosed cover housing, where the outlet openings are made, wherein the generator housing and the housing are equipped with heat-insulating shells from the rejected material and coaxially mounted through the annular gap. Aerosol generation device resting on the casing bottom by the perforated casing receiver, which by means of the annular gap for reversing the distributed aerosol flow is connected to the casing cover outlet holes, is located inside an additional mounting frame, combined with a cooler, which is rigidly connected through a heat-insulating annular shell carrying a bulk baffle, equipped with a cascade of perforated frames communicating with the central chamber, coated with an outer layer of the heat insulator, at that central chamber is communicated with radial discharge channels closed by grids.

EFFECT: disclosed invention provides higher functional reliability of a simple self-contained structure for automatic aerosol fire extinguishing.
