FIELD: fire-fighting equipment; devices for volumetric fire fighting with generated combustion inhabitants in the form of aerosol mixture designed for protection of store and auxiliary rooms, industrial shops, garages, archives, etc. SUBSTANCE: device incorporates pyrotechnical blasting cartridge which burning forms combustion inhibitors in the form of gaseous compounds and ultra dispersing condensated particles, predominantly salts of alkali metals. Blasting cartridges is put into case through heat-resistant interlayer. Sodium hydrocarbonate disintegrates endothermally with creation of additional combustion inhibitors. Aerosol mixture goes through nozzles in cover evenly positioned over periphery into cooling cylinder mounted for axial movement relative to case which ensures adjustment of value of injection clearance depending on rate of burning of blasting cartridge. Pyrotechnical composition of device is not sensitive to shocks, friction, detonation and formed ecologically safe aerosol mixture. EFFECT: effective cooling of aerosol mixture, compactness and robustness of device facilitating its stockpiling. |
