DEVICE FOR 3D FIRE FIGHTING USING DUAL-MODE GENERATORS Russian patent published in 2012 - IPC A62C37/00 

FIELD: fire-fighting means.

SUBSTANCE: invention relates to fire fighting engineering, in particular to equipment for 3D fire extinguishing. The device for 3D fire extinguishing using a dual-mode nonlinear generator comprises elements for fire fighting, interconnected by a fuse. Elements for fire fighting are located in the volume of the room so that their axes intersect at the geometric center of the room, which is defined as the point of intersection of the diagonals of a rectangular parallelepiped or a cube. Fuse connecting the elements for fire fighting with a charge of smoke-forming composition form a closed quadrangle. The elements for fire fighting are based on a dual-mode nonlinear fire-extinguishing aerosol generator, which body is made of two semi-casings with elements of mounting and comprises aerosol-forming charges placed in the cavity the body. At that the charge of the first mode is separated from the charge of second mode by layer of slow-burning fuel. At the end surfaces of discharge acoustic whistles are installed. The charge of fuel of second mode has a developed surface, an additional igniter and is placed in a separate chamber connected to the cavity of the charge through the hole with a layer of slow-burning fuel. The chamber is equipped with the surfaces of discharge, which shape and orientation is selected from the conditions of particular application to ensure intensive mixing.

EFFECT: increased reliability and effectiveness of 3D fire-fighting system.
