FIRE EXTINGUISHING SYSTEM Russian patent published in 2024 - IPC A62C5/00 A62C35/02 A62C31/12 

FIELD: firefighting.

SUBSTANCE: invention relates to firefighting and can be used both for extinguishing and for localizing fires in warehouses of solid combustible materials (SCM), high-rise buildings, on fire trucks, special facilities such as warehouses of artillery ammunition, shells and other facilities with SCM. The system includes two containers with components of aqueous solutions for the production of two-component foam, each the container is connected by a separate sleeve to a component mixing device in the form of a tee, the outlet connected, through a single component mixing sleeve, to a foam generator. The first container contains component A with the specified composition of ingredients, the second container contains component B with the specified composition of ingredients. The foam generator contains a cylindrical inlet channel for feeding components A and B, the outlet of the inlet channel is connected to a cone-shaped chamber with a rigidly connected cylindrical tip at the outlet, on which there is an adjustable air suction device made in the form of a ring with a number of holes around the circumference and placed, rotationally, in the groove of the tip, which is provided with two rows of holes, the cylindrical tip inside is equipped with film-forming grids at the outlet. A single mixing sleeve forms an inseparable structure with the foam generator, in which the length of the mixing sleeve L = t × 0.5 q/f, where: t is the set thickening time of components A and B to a viscosity of 100-200 cSt, q is the second flow rate of the barrel in liters, f is the cross-sectional area of the mixing sleeve.

EFFECT: technical result is to increase the reliability and efficiency of the system with a minimum fire extinguishing time by using a special foam generator design with the recommended composition for fire extinguishing.
