INSTALLATION OF AEROSOL-GAS-EMULSION SURFACE-VOLUME FIRE EXTINGUISHING Russian patent published in 2022 - IPC A62C3/06 

FIELD: fire extinguishing.

SUBSTANCE: invention relates to the field of aerosol-gas-emulsion fire extinguishing, namely to a fire extinguishing installation with a combination of the principles of surface-volume - double fire extinguishing. The installation of aerosol-gas-emulsion surface-volume fire extinguishing contains a container, a siphon tube, an assembly cartridge, an initiating cartridge for ignition, an igniter, fire-extinguishing aerosol cartridges. The siphon tube is located on the side of the container neck and is made corrugated, with a weighting agent installed at its lower end. A fitting with a threaded connection for connection to the distribution pipeline is installed on the outside of the siphon tube; a safety membrane is installed in the siphon tube in front of the fitting. The cartridge is located in the neck of the tank and consists of separate sections connected by a threaded connection, in the lower part of the cartridge there is a plug with holes for the exit of fire extinguishing aerosol, which are closed with a bursting safety disc, in front of the plug there is a spring for the fire extinguishing aerosol feeder with the installed feeder, designed to fix the specified checkers in the cartridge channel. The igniter wire is located at the top of the cartridge, and the igniter is located at the initiation block. The installation contains spray nozzles, the container is filled with a combat solution, which is an emulsion composition.

EFFECT: increasing the reliability of the fire extinguishing installation due to the possibility of working with an abnormal slope, increasing the efficiency of fire extinguishing due to surface spraying of low expansion foam over the area and volumetric extinguishing with a fire extinguishing aerosol, fire extinguishing does not require the use of high-performance pumping equipment.
