METHOD OF FIRE-EXTINGUISHING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC A62C2/00 

FIELD: fire safety.

SUBSTANCE: fire-extinguishing method with use of gas-liquid mixture is carried out by the container in which the extinguishing agent is stored and which is connected to the trigger cylinder with the working gas, the container in which the extinguishing agent is stored is secured by the brackets to the building structure of the facility and it is equipped with the device of release of the gas phase, combined with a measuring probe for the extinguishing agent, and the device forming gas-liquid mixture of vortex type, which is made in the form of a conical mixing chamber with a tangential gas inlet in the upper part, then is connected by the high pressure flexible hose of the working gas such as nitrogen or CO₂ to the container from the starting cylinder. At that the gas supply is carried out by the vortex element, and the feeding of gas-liquid mixture to the central pipeline is carried out from the lower part of the chamber connected to the fire extinguishing agent discharging unit, combined with the safety valve. At that, the vertical pipe of the chamber through the tee is connected to the device of filling of the extinguishing agent and the pressure alarm, and the formed gas-liquid mixture on the central pipeline is directed to the nodal point of the distribution network, and then, through the distribution network to all sprinklers, with each sprinkler or block of sprinklers is provided with a device of orientation in one or two planes.

EFFECT: increasing operation speed of fire-extinguishing system and efficiency of spraying of gas-liquid mixture.
