DEVICE FOR VOLUME EXTINGUISHING OF FIRE Russian patent published in 1997 - IPC

FIELD: fire-fighting equipment. SUBSTANCE: fire extinguisher is a compact structure with coaxial arrangement of functional members. Explosive charge is placed in screen cylinder of cooling unit. Screen cylinder is filled with granules of ablation material. Cooling unit is installed in heatproof body with outlet hole on side surface. Annular space confined between screen cylinder and body ridges, between which outlet holes are located, forms receiver where generated gases and aerosol are mixed and cooled, and pressure of fire extinguishing mixture is equalized. Due to ablation of material of cylinder filler when hot gas-aerosol flow passes between granules without air injection, thrown into protected volume is extinguishing mixture with temperature considerably lower than that of thermal destruction of organic compounds. EFFECT: higher efficiency. 1 dwg
