Problems solved by technology

However, the typical defect of this method is that it only adsorbs harmful substances and cannot degrade harmful substances.
At the same time, it can only deal with harmful substances in the air inside the car, and cannot deal with harmful substances that are mixed in the interior materials of the car and released slowly.

Embodiment 1

[0025] A method for removing peculiar smell in a car. The car is placed in a confined space, the air in the confined space is heated to 40-70°C, and the air in the confined space is circulated. The circulating air successively passes through superfine glass Processing of fiber forming filter layer, catalyst layer and adsorption layer;

[0026] The composition of the catalytic layer is:

[0027] A) 10% nano TiO 2 For the supported cobalt-cerium-zinc-potassium composite oxide, the molar ratio of each component Ti:Co:Ce:Zn:K is 1:0.1:0.1:0.1:0.1;

[0028] B) 5% zirconium-doped iron-manganese-molybdenum-vanadium composite oxide, the molar ratio of Zr:Fe:Mn:Mo:V is 0.1:1:1:1:1;

[0029] C) The balance of ZSM-5 molecular sieve;

[0030] The adsorption layer is an activated carbon adsorption layer loaded with Ag.

[0031] Treated 10 vehicles one after another. After 24 hours of treatment, the vehicles were placed in an outdoor space, their doors and windows were closed, and the air quality ins...

Abstract

The invention discloses a method for removing peculiar smell from an automobile. The method is characterized by putting the automobile in confined space, heating the air in the confined space to 40-70 DEG C and circulating the air in the confined space, wherein the circulated air is successively treated by a filter layer formed by ultrafine glass fibers, a catalyst layer and an adsorption layer. The method has the beneficial effects that the pollutants contained in the automobile are volatilized more quickly by putting the automobile in the confined space to be heated, and the gaseous pollutants in the air in the automobile are catalytically oxidized into oxycarbide in combination with specific catalysts, thus reducing various pollutants to the ppm (parts per million) level.

Description

Technical field [0001] The invention relates to the field of air purification, in particular to a method for removing peculiar smell in automobiles. Background technique [0002] The market demand of family cars in our country makes many cars directly enter the market after they are off the production line. There is no release period for harmful gases and odors of various accessories and materials. If the plastic parts, carpets, roof felts, sofas, etc. installed in the car are not in accordance with Strict environmental protection requirements will directly cause air pollution in the car. [0003] In-vehicle air pollution refers to the poor air quality inside the vehicle due to lack of ventilation and body decoration. The sources of air pollution in the car mainly come from the car body itself and decorative materials, among which toxic substances such as formaldehyde, xylene and benzene have the most serious consequences. [0004] The only domestic technical standard for air pollu...
