KOCHETOV MODULAR FIRE EXTINGUISHING SYSTEM Russian patent published in 2016 - IPC A62C13/00 

FIELD: salvage operation.

SUBSTANCE: invention relates to firefighting equipment. Technical result is achieved by the fact that in the method of modular fire extinguishing, which is carried out by means of the vessel, storing fire-extinguishing substance, and the vessel, in which fire-extinguishing substance is stored, brackets are attached to the building structure of the room and discharge device is equipped with gas phase, combined with measuring probe for fire-extinguishing substance and stop-starting device, for example, electromagnetic type, which is connected via pipeline with tube for feeding fire extinguishing liquid into foam generator that is equipped with inputs for simultaneous supply of liquid and gas, the liquid supply is performed in two directions, comprises forcing fluid axially via feed branch pipe and series-connected and coaxial with it confusor and cylindrical nozzle, and tangential liquid supply is performed through coaxial with cylindrical nozzle in the form of cylinder-conical sleeve on cylindrical part accommodating Vortex annular chamber with branch pipe for supply of liquid, note that at the edges of the ring chamber are two rows of fluid feed tangential channels, having at least three tangential channels connecting the annular chamber with housing cylindrical chamber, to round plate is located perpendicular to axis of the vortex annular chamber and rigidly connected with housing cylindrical chamber, and in its end section perpendicular to round plate is attached slotted nozzle, which consists of two mutually perpendicular rectangular parallelepipeds with throttle through holes of rectangular section connected to the casing cavity.

EFFECT: higher efficiency of fire extinguishing due to usage of high-expansion foam.
