FIRE-EXSTINGUISHING GAS-DISPERSION COMPOUND, WAY OF FIRE EXTINGUISHING AND DEVICE FOR ITS REALISATION Russian patent published in 2009 - IPC A62C2/00 A62D1/00 A62C35/02 

FIELD: medicine, saving agents.

SUBSTANCE: fire-extinguishing gas-disperse compound includes highly disperse and target additives, organosilicone water-repellent agent, the basic powdery inhibitor of burning, gaseous and-or liquefied deterrent or an admixture of a deterrent and a liquid inhibitor where the following components are used as gaseous and-or liquefied deterrent: carbon dioxide modified with dimethylketone or an admixture of carbon dioxide, modified with dimethylketone, and nitrogen or air, or an admixture of dioxide of Carboneum modified dimethylketone, alkylcarbinol, or an admixture of carbon dioxide modified with dimethylketone, and nitrogen or air with alkylcarbinol, and as a liquid inhibitor of burning a solution 5% of iodine or 5-20% solution of an admixture of iodine with Iodidum of alkaline metal or ammonium in alkylcarbinol are used. Way of fire extinguishing is carried out with formation of a fire extinguishing gas-disperse compound in three stages: the first - from capacity-source of gas with a siphon tube and the shut-off and starting arrangement, filled with offered compound of deterrent, an inhibitor and target additive under offered pressure on a signal of the fireman sending box offered compounds of the basic powdery inhibitor of burning, the highly dispersive additive, the target additive for fluidity and an organosilicone water-repellent agent are supplied with not less than 0.3 part of gas or gas-liquid admixture in prechamber; the mixtures, containing at atmospheric pressure, and the above-named admixture is supplied in a prechamber mixture from gas capacity-source on a siphon tube and the connecting tube passing in a tight cover of the prechamber in a punched tubular aerator; the second - formed primary solid liquid-gas admixture is bypassed through the final valve in the tubular vaporising chamber where a gas-dispersion stream is formed; the third - gas-dispersion stream from the tubular vaporising chamber through the final valve at volume, vulgar and-or volume-local suppression is directed in the nozzle block with the nozzles providing rate of the efflux of a stream of the fire extinguishing gas-dispersion structure in a zone of a fire not less 79 m/s. For realisation of a way the modular device is offered.

EFFECT: maintenance of application of structure, a way and the device at an ambient temperature from-60°C to +50°C.
