Abstract
The invention discloses a coalescent wet-type fire evacuation anti-poison and anti-smoke mask which comprises an outer layer, a physical filter layer, a coalescent wet adsorbent layer and an inner layer, wherein adsorbent medical liquid sealed in a thin plastic bag is packed together with a mask main body. According to the invention, coalescent adsorption is applied to respiratory protection article for the first time, and the protection principle is based on coalescent wet adsorption; and specifically, the physical filter layer and the coalescent wet adsorbent layer form two adsorbent filter layers for the fire smoke. The mask worn in the fire disaster can effectively protect from harm of poison and smoke in the fire scene, so as to strive for more time for the persons to safely evacuate and escape.
Description
Technical field
The invention belongs to fire-fighting personal protective equipment technical field, relate to a kind of fire disaster escaping respiratory protection mouth mask, particularly one fuses moist type fire evacuation gas defence smoke-preventing mask.
Background technology
Existing multiple breathing mask on the market, Smoke prevention, anti-dust respirator, but in the event of a fire, be applied to the very few of evacuation.Through investigation, its main cause is:
Breathing mask cost and the maintenance expense that 1, can play obvious protective action are too high, are generally equipped with use unactual;
2, the actual protection effect of respiratory protection mouth mask to the murder by poisoning flue gas that macromolecular material burning produces prepared of the material such as active carbon of low cost is bad, and uses under being not easy to the state of emergency.
Show according to fire incident post analysis data, in the number of fire fatality, that is directly burnt to death by big fire only accounts for 15% of dead sum, and what lose the death of escape ability because of smoke poisoning accounts for more than 85%.Within 2009, Shenyang Wanda sales office fire is exactly such fire together, causes 9 people dead.In morning on March 10th, 2012, chain store's breaking out of fire sold directly to households by Yiwu small item, and 3 firefighterses fall down because of a large amount of toxic smoke of inspiration.
The toxic action of fire smoke is very serious to human injury, needs a kind of practical gas defence smoke-preventing mask of research and development badly, effectively protects escape personnel, make the injury being subject to toxic smoke that it is the least possible when fire occurs, for escape is raced against time.
Summary of the invention
In order to make up the deficiencies in the prior art, the invention provides a kind of using method easy, the efficient mouth mask of flue gas successful, and material therefor low cost, extensively can be ready for use on the fused moist type fire evacuation gas defence smoke-preventing mask of the public place of the densely populated place 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 internal layer, absorption liquid is packed separately, described filtration adsorption layer comprises fused wetting adsorption layer, and fused wetting adsorption layer adsorbs absorption liquid.
Further, described filtration adsorption layer also comprises physical absorption layer.
Further, skin is 30-80g/m
2polyester filament non-woven fabrics, or ventilative good fabric.
Further, physical filtering layer is formed by one or more Material claddings of active carbon, active carbon cloth, molecular sieve, bamboo-carbon fibre; Or the particulate filter be made up of filter paper or the ultra-fine fibre glass paper containing crocidllite is formed.
Further, fused wetting adsorption layer is made up of expanded core, and described expanded core is polyacrylamide.
Further, internal layer is by 10-20g/m
2polyester filament non-woven fabrics form.
Further, adsorbing liquid is Na
2cO
3solution and/or CuCl-MgCl
2solution.
Further, the filtration adsorption layer of described mouth mask may be used for preparation filter malicious box, canister or other filtration members.
The present invention will fuse adsorption applications first on 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 is long, is greater than 45 minutes.Wear this mouth mask in fire, effectively can 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 this mouth mask using method is easy by great many of experiments, 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, be applicable to the respiratory protection in the disaster accident such as volcano, earthquake simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
In figure, 1: skin, 2: physical filtering layer, 3: fused wetting adsorption layer, 4: internal layer, 5: absorption liquid packaging.
Detailed description of the invention
Embodiment 1: this fused moist type fire evacuation protection gas defence smoke-preventing mask is made up of outer (1), physical filtering layer (2), fused wetting adsorption layer (3), internal layer (4), and quantitative absorption liquid packaging (5) is together packed with mask main body.Mouth mask of the present invention filters adsorption layer can form 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
2polyester filament non-woven fabrics, also can be ventilative good fiber fabric as fire proofing firbre is knitted or the material such as gauze.This layer material contact skin without primary stimulus and sensitization, and has good gas permeability and good waterproof action.
Physical filtering layer (2) is formed by one or more Material claddings that active carbon, active carbon cloth, molecular sieve, bamboo-carbon fibre or other physical absorption performance are high.Or the particulate filter be made up of filter paper or the ultra-fine fibre glass paper containing crocidllite is formed.This layer is good to larger particles aerosol adsorptivity, can harmful components in initial absorption flue gas.
Fused wetting adsorption layer (3) is made up 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, absorption liquid carrier when it is mouth mask use, fused wetting adsorption layer materials chemistry performance is stablized simultaneously, heat-resisting, cold-resistant being applicable to uses in 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, and fused wetting adsorption layer also can be only had to form.
Internal layer (4) is by 10-20g/m
2polyester filament non-woven fabrics or other material form, soft pro-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.Absorption liquid is packed in the mode of foil-type plastic bag, is then placed in mask main body packaging.Absorb the fused wetting layer of absorption liquid liquid to the CO of buildings decoration material as releasing when Common materials in the lives such as timber, nitrocellulose, rubber, plastics, artificial silk, wool and finishing material burning
2, H
2s, Cl
2, the pernicious gas such as HCl effectively adsorbs, and carries out secondary filter to aerosol simultaneously.
When fire occurs, adsorbent drug flexible package punch is torn, the absorption liquid mouth mask in packaging is poured on inside mouth mask, can use be worn.
Experiment test throughput is 85L/min, and inspiratory resistance is less than 59Pa, and expiratory resistance is less than 49Pa, wears when being applicable to strenuous exercise, can toxic gas effectively in the disaster accident such as protection against fire, earthquake, volcano.This fused moist type fire evacuation gas defence smoke-preventing mask using method is easy, material therefor low cost, and Social benefit and economic benefit is remarkable.
