Air-conditioning filter for preventing and controlling haze

Abstract

The invention discloses an air-conditioning filter. The air-conditioning filter consists of a filtering layer, a catalyst layer and a filtering layer from inside to outside, the catalyst layer consists of a powdery catalyst, the powdery catalyst is prepared from a carrier, an active component and a catalyst promoter, the carrier is zeolite, and the Si/(Si + Al + P) mole ratio of the framework structure of the zeolite is 0.20. The active component is a mixture of titanium dioxide and cerium oxide, the molar ratio of Ti to Ce is 4:3, the titanium dioxide is of an anatase crystal form, and the weight content of the active component in the catalyst is 0.3% to 10%. The catalyst promoter is silver and ferric oxide, the molar ratio of Ag to Fe is 2:5, and the weight content of the catalyst promoter in the catalyst is 0.3% to 6%. After haze air passes through the air-conditioning filter, 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 an air conditioner filter 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 v...

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 air conditioner 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.
