Fused moist type fire evacuation gas defence smoke-preventing mask
Technical field
The invention belongs to the fire-fighting personal protective equipment technical field, relate to a kind of fire disaster escaping respiratory protection mouth mask, particularly a kind of fused moist type fire evacuation gas defence smoke-preventing mask.
Background technology
Have on the market multiple breathing mask, Smoke prevention, anti-dust respirator, but in the situation of breaking out of fire, what be applied to evacuate is very few.Through investigation, its main cause is:
1, it is too high to play breathing mask cost and the maintenance expense of obvious protective action, generally be equipped with use unactual;
2, the actual protection effect of the respiratory protection mouth mask of the materials such as active carbon of the low cost preparation murder by poisoning flue gas that burning produces to macromolecular material is bad, and is not easy to use under the state of emergency.
Show according to fire incident post analysis data, in the number of fire fatality, only accounted for 15% of dead sum by what big fire was directly burnt to death, because smoke poisoning loses accounting for more than 85% of escape ability death.Shenyang Wanda sales office fire was exactly so together fire in 2009, caused 9 people dead.In morning on March 10th, 2012, the Yiwu small item are sold chain store's breaking out of fire directly to households, and 3 firefighterses fall down because of a large amount of toxic smokes of inspiration.
The toxic action of fire smoke is very serious to the human injury, needs a kind of practical gas defence smoke-preventing mask of research and development badly, effectively protects the escape personnel when fire occurs, and makes its least possible injury that is subject to toxic smoke, for escape is raced against time.
Summary of the invention
In order to remedy the deficiencies in the prior art, it is easy to the invention provides a kind of using method, the efficient mouth mask of flue gas successful, and the material therefor low cost can extensively be ready for use on the fused moist type fire evacuation gas defence smoke-preventing mask of the intensive public place of the personnel such as family, hotel, cinema, dormitory building.
A kind of fused moist type fire evacuation gas defence smoke-preventing mask, comprise skin, filter adsorption layer, internal layer and absorption liquid, filtering adsorption layer is arranged between skin and the internal layer, the absorption liquid is packed separately, described filtration adsorption layer comprises fused wetting adsorption layer, and fused wetting adsorption layer adsorbs the absorption liquid.
Further, described filtration adsorption layer also comprises the physical absorption layer.
Further, skin is 30-80g/m
2The polyester filament nonwoven, or ventilative good fabric.
Further, the physical filtering layer is formed by one or more Material claddings of active carbon, active carbon cloth, molecular sieve, bamboo-carbon fibre; The particulate filter of perhaps being made by the filter paper that contains crocidllite or ultra-fine fibre glass paper consists of.
Further, fused wetting adsorption layer is made of expanded core, and described expanded core is polyacrylamide.
Further, internal layer is by 10-20g/m
2The polyester filament nonwoven consist of.
Further, the absorption liquid is Na
2CO
3Solution and/or CuCl-MgCl
2Solution.
Further, the filtration adsorption layer of described mouth mask can be for the preparation of filter malicious box, canister or other filtration members.
The present invention will be fused adsorption applications first to protective respirator, further, this fused moist type fire evacuation gas defence smoke-preventing mask has physical filtering layer and fused wetting adsorption layer double medium filtration adsorption layer, and adsorption efficiency is high, guard time was long, greater than 45 minutes.Wear this mouth mask in the fire, can effectively protect the injury of scene of a fire toxic smoke, for the more time is striven in escape, protection safety evacuation and escape.Confirm that by great many of experiments this mouth mask using method is easy, gas defence Smoke prevention successful is efficient.This mouth mask low cost can extensively be installed to the places such as hotel, cinema, dormitory building, chemical industrial park, is applicable to simultaneously the respiratory protection in the disaster accidents such as volcano, earthquake.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention;
Among the figure, 1: skin, 2: physical filtering layer, 3: fused wetting adsorption layer, 4: internal layer, 5: absorption liquid packing.
The specific embodiment
Embodiment 1: this fused moist type fire evacuation protection gas defence smoke-preventing mask is comprised of outer (1), physical filtering layer (2), fused wetting adsorption layer (3), internal layer (4), and quantitative absorption liquid packing (5) is together packed with mask main body.Mouth mask of the present invention filters adsorption layer can consist of double-deck adsorption layer for physical filtering layer and fused wetting adsorption layer, also can only have fused wetting adsorption layer.
Outer (1) skin is 30-80g/m
2The polyester filament nonwoven, also can be ventilative good fiber fabric such as fire proofing firbre is knitted or the material such as gauze.This layer material contact skin is without primary stimulus and sensitization, and has good gas permeability and waterproof action preferably.
Physical filtering layer (2) is formed by active carbon, active carbon cloth, molecular sieve, bamboo-carbon fibre or one or more high Material claddings of other physical absorption performance.The particulate filter of perhaps being made by the filter paper that contains crocidllite or ultra-fine fibre glass paper consists of.This layer is good to larger particles aerosol adsorptivity, can tentatively absorb the harmful components in the flue gas.
Fused wetting adsorption layer (3) is made of the expanded core of one deck, this material is the sorbing material of polyacrylamide or other class, material non-toxic, quality is soft, even, have fabulous wetability, the absorption liquid carrier when it is the mouth mask use, fused wetting adsorption layer materials chemistry performance is stable simultaneously, heat-resisting, cold-resistant being applicable to used in the wide temperature range.
The filtration adsorption layer of mouth mask can be made for one deck or which floor physical filtering layer add fused wetting adsorption layer, also can only have fused wetting adsorption layer to consist of.
Internal layer (4) is by 10-20g/m
2Polyester filament nonwoven or other material consist of soft close skin, good air permeability.
Absorption liquid (5) is certain density Na
2CO
3Solution, CuCl-MgCl
2Solution, or other is to the solution of pernicious gas generation physics or chemical reaction, and adsorbent solution can be single solution, also can be mixed solution.The absorption liquid is packed in the mode of foil-type plastic bag, then is placed in the mask main body packing.The CO that the fused wetting layer that absorbs absorption liquid liquid is emitted when common material and finishing material burn in the lives such as buildings decoration material such as timber, nitrocellulose, rubber, plastics, artificial silk, wool
2, H
2S, Cl
2, the pernicious gas such as HCl effectively adsorbs, and simultaneously aerosol carried out secondary filter.
When fire occurs the adsorbent drug flexible package punch is torn, the absorption liquid mouth mask in the packing is poured on the mouth mask inboard, can wear use.
The experiment test throughput is 85L/min, and inspiratory resistance is less than 59Pa, and expiratory resistance is worn when being applicable to strenuous exercise less than 49Pa, effectively the toxic gas in the disaster accidents such as protection against fire, earthquake, volcano.Easy, the material therefor low cost of this fused moist type fire evacuation gas defence smoke-preventing mask using method, Social benefit and economic benefit is remarkable.
