Fire extinguishing equipment with fire nozzle
In one structural arrangement the fire fighting nozzle ( 18 ) is connected to the compressor ( 7 ) of a gas-turbine engine ( 4 ). In the second structural arrangement the fire nozzle ( 18 ) is connected to a screw compressor ( 50 ) connected to a diesel engine ( 47 ). Both types of fire extinguishing equipment have the same fire nozzle ( 18 ), whose mixing chamber ( 19 ) for the generation of a high-speed two-phase dispersive stream ( 21 ) of a bubble structure is made in the form of a block of mixers ( 35 ) with front and rear partitions ( 36,37 ), in between which pipe mixers ( 38 ) are located. Each mixer ( 38 ) is equipped with a confusor ( 43 ) and a diffusor ( 44 ). On the outlet from the fire nozzle ( 18 ) the high-speed dispersive stream ( 21 ) contains droplets of sizes 100-300 μm. The fire nozzle ( 18 ) has a mixing chamber ( 19 ), divided by partitions ( 36, 37 ) to a water supply chamber ( 40 ), air supply chamber ( 41 ) and dispersing chamber ( 39 ). The dispersing chamber ( 39 ) narrows into a gas-dynamic propelling nozzle ( 20 ), from which a high-speed dispersive stream ( 21 ) comes out. The fire nozzle ( 18 ) is connected to a rotating mechanism ( 22 ) which rotates it vertically and horizontally. The control unit ( 2 ) is equipped with a remote control ( 34 ) and connected to an generator ( 3 ).
