Abstract
The invention relates to nitrogen fire extinguishing equipment for an airplane. Liquid nitrogen which is an inert gas and a non-conducting and clean fire extinguishing agent is gasified and then sprayed in a fire scene; and storage tank equipment is advanced and can be used for extinguishing forest fire and high-rise building fire and extinguishing outside fire in the airplane. The temperature of the liquid nitrogen is -196 DEG C and the liquid nitrogen is expanded for more than 700 times at 0 DEG C, high temperature of thousands DEG C on the fire scene enables the liquid nitrogen to be expanded more rapidly, the larger the expanding coefficient is, the rapider the fire extinguishment is. The ozone layer is not damaged and the atmospheric layer is not polluted. The nitrogen fire extinguishing equipment comprises a storage tank (1), a valve (2) and a pipeline , wherein the storage tank (1) is provided with an electro connecting pressure gauge (13), a liquid level meter (14), a safety valve (15), a dispersing valve (10), a charging valve (12), an evaporator (11) and a nitrogen return pipe (9), wherein the charging valve (12) is connected with the evaporator in parallel; a low-temperature liquid pump (3), an insulation pipe (4) and a nozzle (5) are connected to form a nitrogen releasing mechanism; the fire extinguishing storage tank is provided with an automatic control system, a linkage controller (6), a CRT (Cathode Ray Tube) (16), a display monitor system (18), a circuit (17), a linkage control disk (7) and a ZK vacuum meter (19); the circuit (17) is connected with the valve (2), a motor of an ultra-low temperature pump (3) is connected with a feeding valve (8) of the evaporator (11), and when the nozzle receives an alarm, the valve (2) is automatically opened, and the nitrogen is sprayed to a protection region (5).
Description
Technical field
The present invention relates to organizational equipment, aircraft on fire the saving oneself of being hit by a bullet need not be parachuted in the fight, can continue fight after the fire extinguishing.Can go out fire in the aircraft storehouse, fire outside the storehouse of going out again, can also go out forest fire and skyscraper fire make and on firely do not cause disaster.
Install this nitrogen extinguishing equipment on the aircraft, just than the speed of fast hundred times of present equipment fire fighting trucks, extinguishing ability increases by thousand times, the no road of forest fire fighting, fire fighting truck does not increase, and ten thousand People's Armed Police climb up also useless, by not near burning things which may cause a fire disaster, thousands of degree high temperature, human body limit be can't stand.Forest, with skyscraper, fire attack is China, world-famous puzzle.
Social development is fast, and world's skyscraper is more and more, has only the aerial fire brigade of establishment, carries out aerial three-dimensional fire extinguishing with aircraft, is only the unique way that solves this difficult problem.
Fire-fight by water to fall behind era development, the Taiyuan beginning, the water fire extinguishing has been extended active duty, and is more harm than good, and water resource is shortage again, and the hydraulic giant range is less than 20 meters, and water is to hydrocarbon, oils, and the circuit fire extinguishing is powerless especially, contains oxygen in the water, also plays combustion-supporting effect sometimes.It is greatly destructive to article to fire-fight by water, and the article that fire does not burn allow bubble arrive, particularly archive office, library, historical relic class.
Summary of the invention
The aircraft nitrogen extinguishing equipment that I invented can be according to spatial area design storage tank fire-extinguishing apparatus in the aircraft storehouse, size, and shape is preferably installed at aircraft factory.
Aircraft nitrogen extinguishing equipment storage tank multilayer heat insulation device, the special steel plate of internal layer, sanding and polishing, interlayer is established insulation, and the outer aluminium foil multi-lay winding of using is horizontal, vertical, slot type is multiple.Aircraft nitrogen extinguishing equipment is made up of storage tank, control valve, ultra-low temperature pump, electric control valve, adiabatic pipeline, nozzle vaporizer, linkage controller, fire extinguishing control panel, insulated piping.Storage tank connects bleeder valve connecting evaporimeter, can get back to by return-air duct, nitrogen and produce pressure in the storage tank, and metal hose is communicated with spray gun and implements fire fighting.
Storage tank end face dress safety valve, atmospheric valve, Pressure gauge, liquid level meter, vacuum meter, storage tank one end bottom connects evaporimeter, and the other end connects the feed liquor valve.
Open the venting valve during feed liquor earlier, open liquid flowing valve again and fill, when the vent valve flow liquid, stop to adorn liquid, close liquid flowing valve.Opened the evaporimeter valve in 15 seconds in advance during fire extinguishing, make liquid outflow in the storage tank, the self-produced malleation of storage tank is got back to from top in the gasification back, opens fluid valve primer fluid nitrogen pump, carries out the outside fire extinguishing by flexible pipe, shower nozzle.Several shower nozzles are installed at the inherent suitably seat of cabin like flying, connect several electric control valves with pipeline, discharge by 1,2,3,4,5 orders in the aircraft storehouse, as No. 3 position No. 3 control telegraph keys on fire, just open automatically, the bleeder valve telegraph key starts automatically, and nitrogen is transported to the scene of a fire.
When fire extinguishing ejection pressure is not enough, can open liquid nitrogen pump, lift reaches 80 meters.Extinguishing chemical nitrogen reduces oxygen content in temperature and the air rapidly, and fire is extinguished rapidly, reaches the fire order ground that do not cause disaster.Advantage of the present invention is: simple in structure, non-conductive, do not influence aircraft flight, and nonpoisonous and tasteless, the clean extinguishing chemical of pure natural, no chemical synthesis, fire extinguishing leaves no trace rapidly, do not damage any article, get back in the air again after the fire extinguishing and go, the forest fire of going out, the down wind effect is better.
Need bending or movable part can adopt metal hose in the heat-insulated pipe, fall metal hose by the height of aircraft when the scene of a fire and rescue forest fire.Rescue the skyscraper fire and the time put metal hose and put down aerial ladder simultaneously, be convenient to aerial fireman and stand on the aerial ladder and put out a fire.The precedent in the wound world, the great-leap-forward scientific development.Our my late grandfather's invention Chinese character nitrogen has just been expected the nitrogen scorching big fire of going out.
These all valves of nitrogen extinguishing equipment all are the electric auto-control valve.
Cryogenic liquid pump must reach following technical indicator:
Medium temperature-196 ℃
Inlet pressure 0.2-0.65MPa
Outlet pressure 1.0-1.45MPa
The pre-cool time of system≤15 seconds
Fighting nozzle divides several: single flow, and fountain, rotary, single flow can be by the user's request orientation.
