Abstract
The invention discloses a method used for removing peculiar smell of automobiles. The method comprises following steps: an automobile is place in a confined space; the air in the confined space is heated to 40 to 70 DEG C, and is circulated; the circulated air is delivered through a filtering layer formed by ultra-fine glass fiber, a catalyst layer, and an adsorption layer successively for treatment. According to the method, the automobile is placed in the confined space for heating, volatilization of pollutants is accelerated, gas pollutants in the air in the automobile are changed into oxycarbides via catalytic oxidation under action of a certain catalyst, and the content of the pollutants is reduced to ppm grade.
Description
Technical field
The present invention relates to air purification field, be specifically related to a kind of automobile method that eliminates the unusual smell.
Background technology
The market demand of China's domestic automobile makes a lot of automobiles descend production line just directly to come into the market, various joiningPernicious gas and the smell of part and material do not have release period, be arranged on working of plastics in car, carpet, roof felt,If sofas etc., not according to strict environmental requirement, can directly cause the air pollution in car.
In-vehicle air pollution refers to that automotive interior is because the air quality that the reasons such as stuffy, car body finishing cause is poorSituation. In-vehicle air pollution source is mainly from car body itself, decorative material etc., wherein formaldehyde, dimethylbenzene,The noxious material pollution effects such as benzene are the most serious.
The domestic technical standard for in-vehicle air pollution, only has the formal " passenger car of implementing of in March, 2012Interior Air Quality Evaluation guide ", but, " Air Quality Evaluation guide in passenger car " just industry skillArt standard, and permissive legislation. And too low with respect to American-European standard, adopt room air markAccurate upper limit level. According to Germany work out environment inside car standard, content of formaldehyde can not exceed 0.08 milligram/Cubic meter, China's standard is to exceed 0.1 milligram/cubic metre.
For the place to go of pollutant in vehicle air (peculiar smell), current main flow way is all to adopt to inhaleAttached method, adopts the porous materials such as active carbon, the harmful substances such as the formaldehyde in absorbed air. But the allusion quotation of the methodType defect is just to adsorb harmful substance, the harmful substance of can not degrading. Meanwhile, it can only process in car emptyHarmful substance in gas, for the harmful substance that is mixed in automotive interior material and slowly discharges, can not process.
Summary of the invention
The object of the invention is to propose the method for a kind of automobile removal peculiar smell (pollutant), described peculiar smell masterDerive from the organic gas such as benzene,toluene,xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, methacrylaldehydePollutant. After processing through method of the present invention, in Automobile, the content of gas pollutant is in follow-up useTime in permanent reduction.
One of object of the present invention is also to propose a kind of method of processing gas, and the method makes to process automobileAir quality after peculiar smell reaches national statutory standards, can not make to process automobile peculiar smell air pair afterwardsAtmospheric environment pollutes.
For reaching this object, the present invention by the following technical solutions:
Automobile is removed a method for peculiar smell, and automobile is placed in confined space by it, by the sky of described confined spaceGas is warmed up to 40-70 DEG C, and the air of the described confined space that circulates, and the air of described circulation, successively through superThin glass fiber forms the processing of filter course, catalyst layer and adsorption layer, it is characterized in that,
Described Catalytic Layer consists of:
A) the β type ferrosilite of 1%-10%, shown in described β type ferrosilite is composed as follows:
(x+y)M(2/n)O·xFe2O3·yAl2O3·zSiO2·wH2O
In formula, M represents cation, and n is the valence of cation M, x+y+z=1, and z/x is 100-220,W is more than 1 positive integer;
B) V doped with Ce of 5%-15%2O5/(MoO3)x(WO3)1-xWith TiO2Mixture,Ce:V2O5/(MoO3)x(WO3)1-x:TiO2Mol ratio be 0.25:1:2, and described titanium dioxide is anatase crystalline substanceType, described x is 0.1-0.5;
C) ZSM-5 molecular sieve of surplus;
Described adsorption layer is the activated carbon adsorption layer that load has Ag.
The present invention, in the time starting working, is placed in airtight space by automobile, described space preferably with automobile sizeAdapt. The air heat of described confined space is arrived to 40-70 DEG C, preferably 55-65 DEG C. Too low Air TemperatureDegree, can not make materials used in auto manufacturing, such as the plastics such as seat, console, fabric, elastomeric material and variousOrganic pollution in glue class material, be mainly benzene,toluene,xylene, ethylbenzene, styrene, formaldehyde,The organic gaseous contamination such as acetaldehyde, methacrylaldehyde thing, accelerates to evaporate, and too high air themperature makes vapourAutomobile-used rubber, plastic or other material accelerated oxidation are disadvantageous. Therefore the present invention selects the temperature of 40-70 DEG C,To make the speed that the volatilization of pollutant and automobile are aging reach a balance.
The material that automobile engine nacelle, crew module and boot etc. adopt, under the heating of air, also reachesTo 40-70 DEG C, at this temperature, the volatile contaminant being clipped in materials used in auto manufacturing, such as benzene, toluene,The organic gaseous contamination things such as dimethylbenzene, ethylbenzene, styrene, formaldehyde, acetaldehyde, methacrylaldehyde, accelerate volatilize intoEnter air. Through applicant actual measurement, temperature in the time of 55 DEG C, the gas pollutants such as car pond benzene in air, formaldehydeConcentration is at least 3 times of concentration under room temperature, that is to say, at the temperature adopting in the present invention, it volatilize fastDegree be at least room temperature naturally volatilize more than 3 times.
Air after automobile, has been mingled with organic pollution, at flow device, such as fan, blower fan etc.Drive under, successively through ultra-fine fibre glass form filter course, catalyst layer and adsorption layer.
Ultra-fine fibre glass forms filter course, can filter and remove airborne molecule, prevents automobileCause dust pollution.
Form filtered air through ultra-fine fibre glass, enter catalyst layer. In Catalytic Layer, airborneOrganic pollution is mainly benzene,toluene,xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, methacrylaldehydeDeng organic gaseous contamination thing etc., under the catalytic action of catalyst, there is catalytic oxidation, be oxidized to carbon oxygenCompound, its peculiar smell disappears, and is also easy to subsequent treatment. During through adsorption layer, airborne microorganism is in activityUnder the silver-colored effect of charcoal load, killed. Meanwhile, active carbon can the untreated gas pollutant of absorbed portion.Return confined space through the air circulation purifying, continue automobile to process.
Preferably, every 0.5-2 hour, described air enters atmosphere, is reintroduced back to fresh air, to reduceGaseous contamination substrate concentration in circulated air, is beneficial to the volatilization of gas pollutant in automobile.
Through after the processing of about 12-24 hour, then automobile is placed in to the exterior space, seals its door and window,After 24 hours, test its air quality, the content of its every pollutant is all lower than 0.01mg/m3, it is low far awayIn the regulation of " Air Quality Evaluation guide in passenger car ", also lower than the rule with harsh famous DINFixed.
The present invention, by automobile being placed in to confined space heating, makes its contained pollutant accelerate to evaporate,And the specific catalyst of combination (choose specific components A and B component, under the effect of ZSM-5 molecular sieve,Make this catalyst produce cooperative effect), be oxidation of coal by airborne gas pollutant catalytic oxidation in carThing, is reduced to ppm level by various pollutants, not only makes the pernicious gas pollutant volatility in automobile fallLow, reduce the infringement of automobile organic pollution to occupant's health, also make the pollutant evaporatingBe degraded, reduced the pollution to environment.
