High oil product improves discharge standard, and vigorously supports new-energy automobile, is phased out gasoline car, in the case of its two-tube time
Just aobvious effect.But the discharge of industrial tail gas never has good processing means, particularly coal-burning thermal power plants, waste incineration
A series of heavy industry enterprises such as factory, steel plant.In addition to there is conventional PM10 and PM2.5 in the industrial tail gas of these enterprises discharge
Outside dust, also largely there are NOx, SO2、SO2F2, formaldehyde, the chemical compositions such as ortho-xylene, how effective mistake both to have been carried out to dust
Filter, while above-mentioned chemical composition can be carried out again effectively to adsorb and degrade, become industry subject urgently to be resolved hurrily.
Invention content
The object of the present invention is to provide a kind of scavenging materials with air-cleaning function.The filtering of present invention collection is inhaled
The functions such as attached, sterilization, removing and harmful gas, particulates emission are suitable as the purification and processing of industrial tail gas in one.
In order to solve the above technical problems, technical solution provided by the invention is as follows：It is a kind of net with air-cleaning function

(3) after being sufficiently mixed, adhesive is added, adds water, is sufficiently stirred；
(4) it pelletizes, in non-woven fabrics box, obtains degradation composite bed.
Compared with prior art, the present invention is compound including graphene fiber layer, nano-titanium dioxide film layer, degradation successively
Layer and activated carbon fiber layers, the graphene fiber layer are connected with fine circuit, and the graphene fiber layer of electrification can be effectively
Pollutants in air is adsorbed, meanwhile, air pollutants can firmly be lockked by graphene fiber and will not flee from, and air enters in next step
To nano-titanium dioxide film layer, nano-titanium dioxide film layer can effectively absorb the benzene in air, and air is through nanometer two
After thin film of titanium oxide layer enter activated carbon fiber layers, activated carbon fiber layers again to dust, particle and the chemical composition in air into
Row absorption, treated that air enters that degradation composite bed carries out degradation treatment for activated carbon fiber layers, and further applicant is to drop
The ingredient and proportioning for solving composite bed are improved, and improved degradation composite bed can effectively remove NOx in air, first
Aldehyde, ortho-xylene, H2S、SO2、CS2、CH3The chemical compositions such as SH, and effect is clearly, is suitable as the purification of industrial tail gas
And processing.
The gas outlet for the production line that applicant produces 1 ton of sulphur daily at one is mounted with this product, to the tail gas of the production line
It is handled, the tail gas of the production line contains NOx, formaldehyde, ortho-xylene and a series of sulfide, and the tail is handled with the present invention
Comparing result before and after gas is as shown in the table：
By upper figure as it can be seen that the present invention can effectively remove NOx, formaldehyde, ortho-xylene, H in tail gas2S、SO2、CS2、
CH3The chemical compositions such as SH, and effect is clearly, is suitable as the purification and processing of industrial tail gas.
