Problems solved by technology

[0013] (4) Not conducive to children's growth
In addition, due to the weak light and the resulting low air pressure in foggy days, some people will experience laziness and depression in foggy days
[0016] (6) Affect reproductive ability
[0021] The filters in the prior art purify the air through filtration or adsorption, but nitrogen oxides or sulfur oxides in the air cannot be removed by filtration or adsorption

Embodiment 1

[0034] The catalyst is prepared by the impregnation method, the carrier is zeolite beta, the molar ratio of Si / (Si+Al+P) in the framework structure of the zeolite is 0.30, and the active component is V doped with Sb. 2 o 5 / (MoO 3 ) x (WO 3 ) 1-x with TiO 2 Mixture, Sb:V 2 o 5 / (MoO 3 ) x (WO 3 ) 1-x :TiO 2 The molar ratio is 0.25:1:2, and the titanium dioxide is an anatase crystal form, the weight content of the active component in the catalyst is 4%, and the x is 0.25;

[0035] The promoter is silver and palladium, the molar ratio of silver to palladium is 2:5, and the weight content of the promoter in the catalyst is 1%.

[0036] The filter screen includes a frame, at least 6 layers of mesh structure are fixed in the frame, and the mesh structure is sequentially superimposed with a wire mesh support layer, a porous fiber layer, an activated carbon layer, a catalyst layer, a porous fiber layer and Wire mesh support layer.

[0037]When the PM2.5 is 300, the poll...

Abstract

The invention discloses a filter screen. The filter screen comprises a filter part, a catalyst part and an outer frame, wherein the filter part, the catalyst part and the outer frame are separably arranged in a stacked mode, and the edges of the filter part and the catalyst part which are arranged in the stacked mode are fixed through the outer frame. The catalyst part consists of a powdery catalyst, and the powdery catalyst is prepared from a carrier, an active component and a catalyst promoter. After haze air passes through the filter screen, PM2.5 particles, nitric oxide and sulfur oxide are all reduced to the super-low level, the air inside a vehicle is effectively purified, and healthy respiratory systems of persons in the vehicle are protected.

Description

technical field [0001] The invention relates to the field of automobile air purification, in particular to a filter screen for preventing haze. Background technique [0002] Haze weather is a state of air pollution. Haze is a general expression of the excessive content of various suspended particulate matter in the atmosphere, especially PM2.5 (particulate matter with an aerodynamic equivalent diameter less than or equal to 2.5 microns) is considered to cause haze. The "culprit" of the weather. [0003] Fog is an aerosol system composed of a large number of tiny water droplets or ice crystals suspended in the air near the surface. It mostly occurs in autumn and winter, and is the product of condensation (or sublimation) of water vapor in the air near the surface. The existence of fog will reduce the transparency of the air and deteriorate the visibility. If the horizontal visibility of the target is reduced to within 1000 meters, the weather phenomenon of water vapor conde...
