2, at indoor configuration air respiratorresuscitator: air respiratorresuscitator is contained in the knapsack, and knapsack is hung on the wall, and selects to ventilate, do not have solar radiation, target visibility point, and the certain compressed air of deposit uses for wearer's emergency escape in the respirator;
3, to indoor inflation fire extinguishing: during breaking out of fire, captive is at the indoor pipeline valve that is communicated with fixing air accumulator of opening voluntarily, and flue gas is put out a fire to indoor inflation under certain pressure; The deliverer monitors the flue gas output pressure at fixing air accumulator end, timely additional flue gas in fixing air accumulator, or in time close the output pipeline valve according to the fire extinguishing situation;
4, safe escape: when captive is withdrawn in news speed, take off extension air respiratorresuscitator bag on the wall, worn air respiratorresuscitator, carry, breathe pure air in poisonous, harmful, flue gas, anaerobic environment is saved oneself and is fled from the danger zone.
The fire-fighting principle of present technique and advantage:
1, the flue gas that is forced to be filled in the building has captured the space, place, squeeze the air in space, place, because the oxygen in the flue gas has exhausted or has only remained the oxygen of trace in fuel combustion, contain a large amount of carbon dioxide in the flue gas, carbon dioxide can not burn, arrived the effect of air-isolation again, scene of a fire comburant extinguishes automatically because of anoxic flame; Because flue gas can be charged to each corner, room automatically, flame-out area is big, effective;
2, since flue gas in fire building inside, in the very first time, minimum distance stops the naked light burning, therefore can prevent building collapsing accident and personnel burn, can control fire spreading, found escape opportunity, also create advantage for outside fire fighting truck fire fighting for captive;
3,,, can improve self-saving ability, safe escape so can prevent smoke poisoning and anoxic at when escape breathe pure air because captive is carried the air respiratorresuscitator bag;
4, flue gas fire extinguishing, damage product not, it is little to leave over vestige, can reduce property loss;
5, because flue gas is the byproduct of factory, wide material sources, price is low, and the fire extinguishing cost is reduced;
6, present technique is put out a fire to high building fire fighting, has unique advantage.
The specific embodiment
The invention provides a kind of flue gas method for extinguishing fire of using, this method comprises the steps:
