4Deng and the saturated aqueous solution made after by the mixing of 8: 2 ratio of water-soluble flame retardant.Container 1 bottleneck is provided with sealing gasket 4, bottleneck 1 and blind flange 5 are fastening by bolt 6, blind flange 5 is provided with two circular holes, the interior metal carrier pipe 3 of extinguishing chemical and the specification of straight-through container 1 bottom of welding are the ferrule-type compression joint 13 of J12 respectively on two circular holes, the outer metal carrier pipe 8 of extinguishing chemical connects super-fine atomization shower nozzle 7, is provided with ball valve 10 between metal carrier pipe 3 and the outer metal carrier pipe 8 in the extinguishing chemical.High-pressure air source can be with bottled nitrogen or carbon dioxide gas, gas bomb 16 is provided with magnetic valve 15, fire detector 17 circuit connect controller 18 inputs, controller 18 outputs connect magnetic valve 15 inputs, the delivery outlet of gas bomb 16 connects threeway 11 through pressure-reducing valve 14, threeway 11 connects ferrule-type compression joint 13 and super-fine atomization shower nozzle 7 respectively, be provided with gas circuit gate valve 12 between pipe joint 13 and the threeway 11, ball valve 10 gentle switch valves 12 can cut out when transportation, after the installation of this device, the state that the gentle switch valve of ball valve 10 12 is in out when flat.Described super-fine atomization shower nozzle 7 is by sprayer body 71, nozzle 72, conveyor screw 73, cross filter core 74, screen pack 75 is formed, sprayer body 71 is a hollow cylinder, the cavities filter core 74 that was threaded in the sprayer body 1, cross filter core 74 for being provided with the hollow cylinder of a plurality of slotted eyes around it, cross the filter core 74 outer screen packs 75 that are provided with, sprayer body 1 end is a cone, the cone internal cavity is provided with 3～8 nozzle bores, be provided with nozzle 72 in the nozzle bore, the conveyor screw 73 of packing in the nozzle 72, conveyor screw 73 is a cylinder or cone, the outer cylinder of cylinder or cone is provided with helicla flute, the endoporus of conveyor screw 73 and nozzle 72 is an interference fits, and nozzle 72 is threaded with sprayer body 71.Sprayer body 1 one ends are provided with the liquid-state extinguishing agent inlet by the liquid-state extinguishing agent carrier pipe 8 that is threaded, and sprayer body 71 is provided with elevated pressure nitrogen institute or the carbon dioxide inlet is connected with air shooter 9 by pipe joint.When under the effect of liquid-state extinguishing agent 2 at air pressure and after nitrogen or carbon dioxide enter sprayer body 71 inner chambers respectively, biphase gas and liquid flow is along the spiral groove high-speed rotational flow on conveyor screw 73 outer cylinders, from nozzle 72 rotation ejection at a high speed, and be atomized into fire smothering gas colloidal sol.
Cold preparation aerosol fire-extinguishing device is work like this.When fire takes place, the fire detector 17 that is installed in (in the room) in the guard plot just sends fire signal to controller 18, controller is opened magnetic valve 15 or manual unlocking magnetic valve 15 immediately automatically, nitrogen (or carbon dioxide) gas in the high-pressure gas cylinder 16 is after pressure-reducing valve 14 reduces to 0.5～2Mpa, one road gas enters liquid fire extinguishing agent container 1 by ferrule-type compression joint 13, under the effect of gas pressure in the container 1 liquid extinguisher 2 through extinguishing chemical carrier pipe 3,8 arrive super-fine atomization shower nozzle 7, and another road gas enters super-fine atomization shower nozzle 7 by gas piping 9.Liquid-state extinguishing agent 2 and nitrogen or carbon dioxide are mixed into gas, liquid two-phase in shower nozzle 7 inner chambers.This gas, when liquid two-phase rotates ejection at a high speed from nozzle 72, because the collision pulverization of centrifugal atomizing effect and air-flow, it is little mist pearl below 5 microns that liquid-state extinguishing agent 2 just becomes particle diameter, the general water smoke of the specific area of the liquid-state extinguishing agent particulate in this fire smothering gas colloidal sol drips big more than 2000 times, thereby can be suspended in the air and and spread rapidly in the scene of a fire, moisture content in diffusion process in this liquid extinguisher particulate evaporation rapidly becomes steam, the solid extinguishing agent particulate that volume becomes littler then continues to be suspended in the air, and being full of the whole scene of a fire equably, the particle diameter that loses moisture content is the extinguishing chemical solid particle and the gas of 100 nanometers～1 micron, the common aerosol shape material of forming of steam with fire extinguishing effect.After this fire smothering gas colloidal sol was sprayed onto the scene of fire, because the evaporation of water heat-absorbing action has reduced fire scene temperature, and air had been got rid of in the rapid expansion of steam, and the oxygen concentration in the scene of a fire is reduced, and has played the effect of fire smothering.Destroy the chain reaction of burning owing to being suspended in after airborne solid extinguishing agent particulate touches comburant simultaneously, played Chemical Inhibition fire extinguishing effect.Cooling, suffocate and the comprehensive function of Chemical Inhibition under, comburant will stop burning and also finally extinguish.
Experiment showed, that this aerosol with fire extinguishing effect can put out A, B, C class fire fast.The utility model can be applicable to the total flooding fire protection of relative closure or hemi-closure space.
