Abstract
The invention utilizes substances (powder or liquid) which can decompose and release CO2 gas, therefore, a packaging container is burst and extinguish substances (powder or liquid) in a bag spray outto cover a fire danger part. A temperature sensing self-control dry chemical projectile is disclosed. The dry chemical projectile can be prepositioned in positions and places with heat sources and incident fire danger such as automobile engine cases, jack boxes, power houses, boiler rooms, cable channels and the like, thereby realizing automatic guard, temperature sensing self-response explosion and fire danger extinguishment.
Description
Technical field
The present invention relates to fire-fighting domain, especially relate to a kind of temperature sensing self-control in the powder fire extinguisher bomb.
Background technology
About 8: 25 on the 5th June in 2009, one No. 9 bus burns near the North 3rd Ring Road, Chengdu, causes 27 people wrecked through tentatively examining, and 76 people are injured.This painful incident allows a lot of citizen all be difficult to accept.The reason of self-burning of vehicle is a lot, and modal have two kinds: oil circuit fault and external high temperature influence.During self-burning of vehicle, fire is lighted from the preceding cabinet of automobile mostly.In the preceding cabinet of automobile oil and energising are arranged, if oil pipe is aging to break, reasons such as joint is loosening, accidental injury cause fuel leakage, meet the scorching hot high temperature of electric spark, battery short circuit and engine exhaust or the carbon deposit Mars of ejection again by chance, perhaps serious grade of carburetor automobile tempering all causes fire easily.In full summer the time, temperature can reach 60 ℃～70 ℃ in the compartment, and lighter, perfume is as easy as rolling off a log ignition under being exposed to the sun of sunlight, thereby self-burning of vehicle takes place.At present, the measure of automobile fireproof mainly is to be equipped with dry powder extinguisher, because dry powder extinguisher must manually start after the generation fire, because part driver and conductor shortage to dry powder extinguisher use knowledge, sometimes is difficult in time, use dry powder extinguisher to put out fire effectively and cause disastrous consequence.Existing fire extinguisher bomb mostly is that ammunition is ignited (electrical fuze or gunpowder fuse), has utilized kindling material, and potential safety hazard is arranged.Temperature-sensitive glass marble AS for building need connect high-pressure water when awaiting orders, and is inapplicable for no high-pressure water place.Present dry powder extinguisher and foam annihilator do not have the Autoattendant function, and container cost height.The self-burning of vehicle accident takes place frequently, and needs the self-extinguishing equipment badly.
Summary of the invention
Problem to be solved by this invention is, utilizes material (powder or liquid) can decompose in certain set point of temperature and discharges CO2 gas, and packing container is burst, and extinguish material (powder or liquid) ejection covers the fire position in the bag.
Place in advance in position and place that the present invention is used in car engine cabinet, distribution box, power house, boiler room, cable duct etc. to be had thermal source and fire easily takes place, Autoattendant, and temperature-sensitive puts out fire from the response outburst.
The specific embodiment
Embodiment 1:
Packaging material: aluminium foil, aluminum foil composite paper, aluminum-plastic composite membrane.Utilize the thermal conductivity of aluminium foil good, dilatation is little during expansion, and is nonflammable, is difficult for leaking, and air-tightness is good, and explosive force is big.If merely with paper or polybag, after packing is met fiery being ignited, cause gas leakage, then there is not the demolition effect of feeling suffocated.Bigger force of explosion helps covering the more large tracts of land scene of a fire.
Thermal decomposition gas exhausted material (having the fire extinguishing effect concurrently): 30-60 ℃ of proportion 1.586 of carbonic hydroammonium decomposition temperature (adds only on a small quantity, inspire the watchful effect of smell that has concurrently), sodium acid carbonate (host, decomposition starting temperature 65 degree) density 2.20, saleratus (decomposition temperature 100-120 degree) relative density 2.17, urea (auxiliary material, decomposition temperature 132 degree).Preferred sodium acid carbonate (sodium bicarbonate).Sodium bicarbonate molecular formula: NaHCO3 adds thermal decomposition and generates: sodium carbonate+water+carbon dioxide.
Fire-fighting powder: commercially available extinguish material, handle through moistureproof anti-caking.Common have silication sodium chloride, potassium chloride, sodium carbonate, potash, sodium bicarbonate (sodium acid carbonate), an ammonium phosphate salt, or other fire proofings.
Processing method: with weight be 5% carbonic hydroammonium, 95% sodium acid carbonate mix the back quantitative package temperature-sensitive of the present invention from responding dry chemical projectile.
Preferably vacuumize and pack with aluminium foil bag.Quantitative package weight 0.1-20 kilogram.Preferred 0.5-2 kilogram.More preferably 1 kilogram.Select suitable volume and quantitative, help breaking out response speed.
Using method: being placed in advance needs the fireproof position.
Embodiment 2:
Manner of packing: outer bag cover inner bag (sack cover pouch): inner bag (pouch) dress acidic liquid, outer bag (sack) dress powder.
The temperature-sensitive initiating device:
With acidic liquid (add antifreezing agent and adjust freezing point) splendid attire (aluminium foil bag) in inner bag, seal with the hot melt material of regulation fusing point at subzero 50 degree, surfactant foaming agent, polyvinyl alcohol foam stabilizer.In environment temperature is delivered to bag, when reaching the temperature of hot melt material, seal automatically and open, acid liquid is revealed, and immediately with the material reaction of getting angry, produces a large amount of gases and makes the explosion of outer bag, and dry powder and foam spray simultaneously.
Acids is optional: hydrochloric acid, and sulfuric acid, phosphoric acid, oxalic acid, citric acid waits various inorganic and organic acids.Preferred hydrochloric acid.
The extinguish material of getting angry is optional: ammonium chloride, and ammonium sulfate, aluminum sulfate, alum (potassium alum), alums (ammonia-alum) etc. are multiple.Preferred sodium acid carbonate.
Chemical principle: hydrochloric acid+sodium acid carbonate---reaction generates rapidly: sodium chloride+water+carbon dioxide.
