Problems solved by technology

[0011] 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.
Although there are some means of purifying air by chemical means, such as using various chemical reagents or catalysts, etc., they generally require higher temperatures and have more restrictions on the use environment.
[0012] After searching the existing technologies, the inventor found that there is no technology to catalyze air at room temperature, decompose organic pollutants in the air, reduce smog particles, and reduce the concentration of pollutants to ppm level

Abstract

The invention discloses an air conditioner filter for preventing and treating haze. The air conditioner filter for preventing and treating the haze comprises a filtering part, a catalyst part and an outer frame, wherein the filtering part and the catalyst part are separably stacked; the outer frame is used for fixing the edge of the filtering part and the catalyst part which are stacked; the catalyst part is made from a powdery catalyst and comprises a carrier, an active component and a promoter. After haze air is filtered by the air conditioner filter, PM2.5 particles, nitric oxides and sulfur oxides in are reduced to an extremely low level, air in a car is effectively purified, and the health of a respiratory system of a person in the car can be 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] Haze, also known as haze (smog), particles such as dust, sulfuric acid, nitric acid, and organic hydrocarbons in the air can also make the atmosphere cloudy. The phenomenon that the horizontal visibility of the target is 1000-10000 meters is called light fog or mist (Mist). Atmospheric humidity should be saturated when fog is formed (if there are a large number of condensation nuclei, saturation may occur if the relative humidity does not necessarily reach 100%). ...
