METHOD OF DISPERSE GAS FIRE EXTINCTION AND DEVICE FOR METHOD IMPLEMENTATION Russian patent published in 2009 - IPC A62C5/00 A62C13/20 A62D1/06 

FIELD: fire safety.

SUBSTANCE: invention concerns fire fighting equipment and is intended for extinction of fires of A, B, C, grades and power plants of up to 7000 V voltage hands-free. Method of disperse gas extinction of inflammable fluids and fuel and suppression of deflagration burning of air-gas and dust-gas formations by feeding disperse gas flow of fire extinguishing fluid from module device to fire area involves formation of inhibiting disperse gas phase with juvenile surface and flegmatising dispersion medium of the disperse gas flow out of supercritical fluid obtained by proposed method, involving pyroelement initiation at shutoff/launching device, simultaneously with thermochemical charge initiation with the help of the claimed device. Device can be applied in automatic and autonomous fire fighting systems and features gas cylinder shutoff/launching device in the form of at least two-layer wad pressed in flushing valve case. Lower wad part contacting gas cylinder content is made of thermomelting foil or plate, and upper external wad part is made of elastic pyroelement with electric igniter commuted to electric pyrocartridge launcher unit.

EFFECT: enhanced fire extinction efficiency in hazardous facilities of coal and ore mining, chemical, oil and nuclear power industries, in transport, industrial facilities and buildings, storehouses and garages, suppressed deflagration burning of air-gas and dust-gas formations.
