Description
Technical field
The present invention relates to technical field of air purification, be specifically related to a kind of breathing mask possessing filtration and purification function.
Background technology
Breathing mask is as personal protection equipment, and for the respiratory apparatus to personnel, eyes and skin of face provide effective protection.Mask by face shield, wireway and canister composition, face shield can, directly with canister or filter malicious box and be connected and use, be called direct-connected; Or with wireway and canister with filter malicious box and be connected and use, be called catheter type.Gas mask can select the canister of various model respectively according to requirement of shelter, be applied in chemical industry, warehouse, scientific research, various poisonous, harmful operating environment.
Common breathing mask is made up of face shield and canister (or filter element).Face shield comprises the parts such as cover body, eye window, communication, respiratory valve and headband (or helmet).Canister is in order to purify toxic gas, and these 2 kinds of materials also can be mixed and made into filter, be assembled into filter element by in-built filter poison layer and adsorbent.Lighter (about 200 grams) canister or filter element can directly be connected on face shield, and heavier canister is connected with face shield by wireway.
Canister is generally cylindrical, is made up of metal or plastics, and surperficial overbrushing is with alkali prevention paint.Canister divides has particulate filter and without particulate filter two kinds, little without particulate filter canister resistance, is more conducive to prolonged labor operating environment, is generally used for the industry that petrochemical industry and steel-making coal etc. are applicable to prolonged labor operation protection.There is particulate filter canister can filtering toxic smoke, malicious mist, biological warfare agent and radioaerosol; Can toxic agent steam effectively in absorbed air without particulate filter canister.Be placed in the air draft of ventilation or suction apparatus as scheduled or gas outlet.For breathing mask be belong to individual protective articles, personnel wear a gas mask breathe time, the external world be contaminted air through canister filter become clean air for personnel breathe.Filter element has filter paper, glass fibre or other synthetic materials.Be through the active carbon of process in filling layer, be used for adsorbing for different poison gas.
In various dust industry, its breathing mask structure used is simple, and it generally adopts direct-connected breathing mask, and its filter element (canister) only comprises filter course, with Chalk-dust filtering.But in actual application, produce the environment of dust, generally can produce various chemical substance, pungent peculiar smell can be produced, cause healthy.Such as at paper industry, its operating environment has very large dust, and have fibre object to rot and various dusty gas that papermaking operation produces, but its breathing mask adopted only possesses filtering function simultaneously, not there is filtration, eliminate the effect of pernicious gas, the healthy of operator can be damaged.
Summary of the invention
The object of the invention is to propose a kind of breathing mask possessing filtration and purification function, it adopts specific expiration and air suction structure, coordinate the canister without particulate filter, under the prerequisite realizing filtering function, catalysis can also be carried out to air, by the harmful substance in air, such as nitrogen oxide, oxycarbide, organic odor contamination such as benzene, toluene, dimethylbenzene, ethylbenzene, styrene, formaldehyde, acetaldehyde, methacrylaldehyde etc., decompose, oxidation is or/and absorption, bactericidal purifying is carried out to air, guarantee filtered air is clean, protect the healthy of operator.
For reaching this object, the present invention by the following technical solutions:
Possess the breathing mask filtered with purification function, be made up of face shield and canister; Face shield comprises cover body, eye window, communication, respiratory valve and securing member, it is characterized in that, also comprises the double-deck outlet valve or multilayer outlet valve that are made up of the expiration valve block of two or more mutual tandem compounds; Grid is provided with between described expiration valve block and between expiration valve block and cover body, the bottom of described mask body is provided with air inlet, described air inlet is connected with canister by wireway, the first adsorption element superposed before and after described canister comprises, catalytic member and the second adsorption element.
Described first adsorption element is provided with fibrous filter layer, and described fibrous filter layer is superimposed with paper fiber thing filter course and ultra-fine fibre glass thing filter course.
Described catalytic member is provided with catalyst layer, and described catalyst comprises following component,
A) nano-TiO of 6%-20%
2the cobalt cerium zinc kalium composite oxides of load, the mol ratio Ti:Co:Ce:Zn:K of its each component is 1:(0.05-0.1): (0.05-0.1): (0.05-0.1): (0.05-0.1);
B) the ferrimanganic molybdenum vanadium oxides composite of the zirconium doping of 3%-8%, the mol ratio of Zr:Fe:Mn:Mo:V is (0.02-0.2): 1:(0.5-1): (0.5-1): (0.5-1);
C) ZSM-5 molecular sieve of surplus.
Described second adsorption element is provided with adsorption layer, and described adsorption layer is made up of the nano titanium oxide of active carbon and Ag-bearing, and its mixing quality such as, than being 5:1-2:1,4.5:1,4:1,3.5:1,3:1 etc.
The preparation method of described catalyst can take conventional infusion process and other alternatives, the prior art unrestricted choice that those skilled in the art can grasp according to it, and the present invention repeats no more.
By breathing mask of the present invention, the air of suction enters the first adsorption element, in the first adsorption element, successively through the filtration of paper fiber layer and ultra-fine fibre glass layer, filters the particle in air and macromolecular substances.
Air after filtering enters catalytic member subsequently, and in catalytic member, the organic pollution in air, such as formaldehyde etc., catalyzed oxidation, becomes harmless or be easy to other organic matters of absorbing.
Air after catalysis, enters the second adsorption element.In air, the organic pollution of catalyzed oxidation is absorbed by active carbon, and is distributed in the silver in active carbon, kills virus to the microorganism in air, thus reduces the content of bacterium.
The present invention, by choosing specific components A and B component, makes this catalyst produce cooperative effect, under the prerequisite ensureing basic dedusting function, makes this breathing mask significantly drop to 0 to haze PM2.5 in air.Simultaneously active high, can catalytic action be played under room temperature, the organic matter degradations such as the formaldehyde in air, benzene are called carbon dioxide, and be higher valence state by harmful oxysulfide, nitrogen oxide catalytic oxidation, and then with charcoal absorption, various pollutant is reduced to ppm level.The removal of benzene,toluene,xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, methacrylaldehyde reaches less than 0.01 milligram/cubic metre, significantly reduces the content of microorganisms in circulating air simultaneously.
