Description
Technical field
The present invention relates to air purification field, be specifically related to a kind of automobile and eliminate the unusual smell method.
Background technology
The market demand of China's domestic automobile makes a lot of automobile descend production line just directly to come into the market, pernicious gas and the smell of various accessory and material do not have release period, if be arranged on the working of plastics in car, carpet, roof felt, sofa etc. not in accordance with strict environmental requirement, the air pollution in car directly can be caused.
In-vehicle air pollution refers to the situation of the air quality difference that automotive interior causes due to reasons such as stuffy, car body finishings.In-vehicle air pollution source is mainly from car body itself, decorative material etc., and wherein the noxious material pollution effect such as formaldehyde, dimethylbenzene, benzene is the most serious.
The domestic technical standard for in-vehicle air pollution, only has " in passenger car Air Quality Evaluation guide " that in March, 2012 formally implements, and but, " in passenger car Air Quality Evaluation guide " be a Technical specifications just, and permissive legislation.And relative to too low American-European standard, have employed the upper limit level of room air standard.According to the environment inside car standard that Germany works out, content of formaldehyde can not more than 0.08 milligram/cubic metre, and China's standard is can not more than 0.1 milligram/cubic metre.
For the place to go of pollutant in vehicle air (peculiar smell), current main flow way is all adopt absorption method, adopts the porous materials such as active carbon, the harmful substances such as the formaldehyde in absorbed air.But the typical defect of the method is, just adsorb harmful components, harmful substance of can not degrading.Meanwhile, it can only process the harmful substance in car in air, for being mixed in automobile interior material and the harmful substance of slow releasing, can not process.
Summary of the invention
The object of the invention is to propose a kind of method that peculiar smell (pollutant) removed by automobile, described peculiar smell is mainly derived from the organic gaseous contamination things such as benzene,toluene,xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, methacrylaldehyde.After method process of the present invention, in Automobile, the content of gas pollutant forever reduces within the time of follow-up use.
An object of the present invention is also to propose a kind of method processing gas, and the method makes the air quality processed after automobile peculiar smell reach national statutory standards, and the air processed after automobile peculiar smell can not be made to pollute atmospheric environment.
For reaching this object, the present invention by the following technical solutions:
The method of peculiar smell removed by a kind of automobile, automobile is placed in confined space by it, by the atmosphere temperature rising of described confined space to 40-70 DEG C, and the air of the described confined space that circulates, the air of described circulation, successively form the process of filter course, catalyst layer and adsorption layer through ultra-fine fibre glass, it is characterized in that
Described Catalytic Layer consists of:
A) Al of 10%
2o
3the Ce/Zr composite oxides of load, the mol ratio Ti:Ce:Zr of its each component is 1:0.08:0.08;
B) V of 5%
2o
5/ (MoO
3)

0.6/ TiO
2composite oxides, wherein the mol ratio of V:Mo:W:Ti is 2:0.4:0.6:1;
C) ZSM-5 molecular sieve of surplus;
Described adsorption layer is the activated carbon adsorption layer that load has Ag.
Automobile, when starting working, is placed in airtight space by the present invention, and described space preferably adapts with automobile size.By the air heat of described confined space to 40-70 DEG C, preferred 55-65 DEG C.Too low air themperature, materials used in auto manufacturing can not be made, organic pollution in the such as plastics such as seat, console, fabric, elastomeric material and various glue class material, the mainly organic gaseous contamination thing such as benzene,toluene,xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, methacrylaldehyde, acceleration evaporates, too high air themperature, then making automobile rubber, plastic or other material accelerated oxidation, is disadvantageous.Therefore the present invention selects the temperature of 40-70 DEG C, reaches one balance to make the volatilization of pollutant and automotive weathering speed.
The material that automobile engine nacelle, crew module and boot etc. adopt, under the heating of air, also 40-70 DEG C is reached, at such a temperature, the volatile contaminant be clipped in materials used in auto manufacturing, the organic gaseous contamination things such as such as benzene,toluene,xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, methacrylaldehyde, accelerate volatilization and enter air.Through applicant's actual measurement, temperature is 55 DEG C time, and the concentration of the gas pollutants such as car pond benzene in air, formaldehyde is at least 3 times of concentration under room temperature, and that is, at the temperature that the present invention adopts, its evaporation rate is at least more than 3 times that room temperature is volatilized naturally.
Air after automobile, has been mingled with organic pollution, at flow device, under the drive of such as fan, blower fan etc., successively forms filter course, catalyst layer and adsorption layer through ultra-fine fibre glass.
Ultra-fine fibre glass forms filter course, can filter the molecule removed in air, prevent from causing dust pollution to automobile.
Form filtered air through ultra-fine fibre glass, enter catalyst layer.In Catalytic Layer, organic pollution in air, the mainly organic gaseous contamination thing etc. such as benzene,toluene,xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, methacrylaldehyde, under the catalytic action of catalyst, there is catalytic oxidation, be oxidized to oxycarbide, its peculiar smell disappears, and is also easy to subsequent treatment.Through adsorption layer, the microorganism in air, under the effect of activated carbon supported silver, is killed.Meanwhile, active carbon can the untreated gas pollutant of absorbed portion.Air through purification loops back confined space, continues to process automobile.
Preferably, every 0.5-2 hour, described air enters air, is reintroduced back to fresh air, to reduce the gaseous contamination substrate concentration in circulating air, is beneficial to the volatilization of gas pollutant in automobile.
After the process of about 12-24 hour, then automobile is placed in the exterior space, close its door and window, test its air quality after 24 hours, the content of its every pollutant is all lower than 0.01mg/m
3, it is well below the regulation of " in passenger car Air Quality Evaluation guide ", also lower than with the regulation of harsh famous DIN.
The present invention is by being placed in confined space heating by automobile, the pollutant contained by it is made to accelerate to evaporate, and (choose specific components A and B component in conjunction with specific catalyst, under the effect of ZSM-5 molecular sieve, this catalyst is made to produce cooperative effect), be oxycarbide by the gas pollutant catalytic oxidation in air in car, various pollutant is reduced to ppm level, the hazardous air pollutants volatility in automobile is not only made to reduce, decrease the infringement of automobile organic pollution to occupant's health, also the pollutant evaporated is made to be degraded, decrease the pollution to environment.
