POWDER FIRE EXTINGUISHING MODULE AND METHOD OF FLUIDISING FIRE EXTINGUISHING POWDER IN MODULE Russian patent published in 2024 - IPC A62C35/02 A62C31/00 

FIELD: fire-fighting equipment.

SUBSTANCE: group of inventions relates to fire-fighting equipment, namely to a method for fluidisation of fire extinguishing powder in a powder fire extinguishing module and to a powder fire extinguishing module. At that, method of fluidisation of fire extinguishing powder includes supercharging of module to working pressure with combustion products formed during combustion of combined charge of gas generator, with subsequent pulse release of said pressure, wherein supercharging at the first stage is carried out to pressure equal to 0.1÷0.5 working pressure, with combustion products formed during combustion of grains burned during time τ₁, at the second stage, supercharging is carried out with combustion products formed during combustion of grains burned during time τ₂, wherein τ₁ less τ₂ by 3-4 times. Inventions can be used to protect production, storage and household premises, motor and luggage compartments of cars, heavy, quarry, agricultural equipment and other road vehicles and trailers, where during their operation the fire extinguishing module can be subjected to high operational loads (shaking and/or vibration).

EFFECT: increasing the efficiency of fire extinguishing due to the uniform and complete fluidisation of the fire extinguishing powder, including the compacted one.
