PROCEDURE FOR OBTAINING OF GAS-POWDER MIXTURE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC A62C13/00 

Abstract RU 2552836 C1

FIELD: fire safety.

SUBSTANCE: procedure for obtaining of gas-powder mixture contains aeration of the fire-extinguishing powder by means of compressed air supply using aeration devices located in bottom part of the tank and connected with compressed air source to the cavity of the tight tank with fire-extinguishing powder. When in the specified tank work pressure is achieved via the siphon pipe the created gas-powder mixture is removed from this tank with further creation using the appropriate means of the single jet or multi-jet flow of the gas-powder mixture supplied to the fire source. The gas-powder mixture removed from the specified tank is accelerated in the specified siphon pipe by means of the compressed gas jet supply to the siphon pipe via its inlet hole and coaxial with it, at that ensuring possibility of the ejection in the siphon pipe of gas-powder mixture created in the tank. Devices for the compressed gas jet supply in the siphon pipe via its inlet hole and coaxially with it are made as nozzle with channel having permanent or variable cross-section coaxially installed relatively to the axis of the siphon pipe for the compressed gas jet supply to the siphon pipe via its inlet hole; at that the nozzle is connected either with the same compressed air source as the aeration devices of the fire-extinguishing powder in the tank, or with the appropriate compressed air source.

EFFECT: improved efficiency and quick action of fire fighting system.
