Description
Technical field
The present invention relates to technical field of air purification, be specifically related to a kind of vehicular air purifier.
Background technology
In recent years, along with popularizing of self-propelled vehicle, increasing family starts to have various self-propelled vehicle.But along with the high speed of self-propelled vehicle is popularized, the problem of in-vehicle air pollution is more and more appeared in one's mind in face of customer.
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 toxic substance pollution effect such as formaldehyde, dimethylbenzene, benzene is the most serious.In September, 2012, a " healthy automobile examining report " shows that 11 sections of mainstream car design may exist carcinogenic risk, and carcinogen contains carcinogenic substance from in-car air quality.
The domestic technical standard for in-vehicle air pollution, only has " in manned vehicle Air Quality Evaluation guide " that in March, 2012 formally implements." in manned vehicle Air Quality Evaluation guide " is according to the kind of volatile organic matter in air in car, source and the analysis to the boiling characteristics of the main interior material of vehicle own, determine 8 kinds mainly by control material, define the concentration requirement of benzene in air in car, toluene, dimethylbenzene, ethylbenzene, styrene, formaldehyde, acetaldehyde, acrolein.
But, " in manned vehicle 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 meter, and China's standard is can not more than 0.1 milligram/cubic meter.
At present, for the purification of air in car, most customer puts the porous mass such as active carbon, pomelo peel, the characteristic of the porous of this kind of matter utilization own car is built-in, can adsorb the partial aromatic hydrocarbon in car in air, but it can not purify and point takes off described aromatic pollution.Although there are some means utilizing chemical mode to purify the air of a room, such as utilize various chemical reagent or catalyst etc., it generally needs higher temperature, also more to environment for use restriction.
Separately there is some consumers, in car, put the volatile matters such as perfume, with the fragrance atmosphere of volatile matter itself, cover the sharp aroma of in-vehicle exposure thing.But these class methods do not reduce the concentration of benzene in air, toluene, dimethylbenzene, ethylbenzene, styrene, formaldehyde, acetaldehyde, acrolein in car, on the contrary because the volatile matters such as the perfume that adopts contain ethanol, methyl alcohol etc., air in car is caused and again pollutes.
Retrieve prior art through contriver to find, also do not adopt room temperature catalytic air at present, and the organic contaminant in air is decomposed, and reduce haze particle, pollutant levels are reduced to the technology of ppm level.
Summary of the invention
The object of the invention is to propose a kind of in-car air purifier, it first carries out catalysis to air in car, benzene,toluene,xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, acrolein are decomposed or oxidation, then enters follow-up adsorbed layer, carry out adsorbing and sterilization.
For reaching this object, the present invention by the following technical solutions:
A kind of vehicular air purifier, comprise housing, centrifugal blower, catalytic member, filtration adsorption element, wherein centrifugal blower, catalytic member, filtration adsorption element are arranged in the cavity of housing, and centrifugal blower is arranged on the middle part of housing hollow; The both sides of housing offer air outlet respectively, and the side, bottom of housing is provided with power interface; Housing upper end offers several air intake vent, and the below of air intake vent is provided with catalytic member, and the below of catalytic member is provided with filtration adsorption element.
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 filtration adsorption element is provided with adsorbed layer, and described adsorbed 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.
When the present invention starts shooting, by the rotation of centrifugal blower, for the wind circulation in housing provides power, the air in car is made to pass through air intake vent, in car, air is after air intake vent, respectively by catalytic member, in catalytic member, benzene, toluene, dimethylbenzene, ethylbenzene, styrene, formaldehyde, acetaldehyde, acrolein is by part or all of oxidative breakdown, then adsorption element is entered, in adsorption element, the compound of particulate matter and decomposition or decomposed is adsorbed, simultaneously, in adsorption element, the silver of load plays the effect of killing microorganisms, comprehensive decontamination has been carried out to gas in car, subsequently the air after purification is sent housing.
The present invention is by choosing specific components A and B component, this catalyst is made to produce cooperative effect, simultaneously active high, catalytic action can be played under room temperature, the organic matter degradations such as the formaldehyde in air, benzene are called carbon dioxide, and are higher valence state by harmful oxysulfide, oxides of nitrogen catalytic oxidation, and then with charcoal absorption, various pollutants is reduced to ppm level, well below with harsh famous European standard.
