Abstract

The invention relates to a wall flow type honeycomb formaldehyde-removing air conditioner filter element. A formaldehyde-removing material of the air conditioner filter element is activated carbon, modified activated carbon, activated carbon fibers, a molecular sieve, manganese oxide, Au/CeO2, Au/FeOx and the like. A supporting material is ceramic fiber or glass fiber; an inorganic adhesive is silica sol or aluminum sol; and an organic adhesive is an acrylic emulsion, an epoxy resin adhesive or a polystyrene emulsion, and an extrusion aid is sesbania powder. According to the invention, the formaldehyde-removing material is mixed with the fibrous support body, the adhesives and the extrusion aid for direct molding, so that the material utilization rate is improved, and the production cost is reduced; and the adopted formaldehyde-removing material has better formaldehyde adsorption and decomposition effects and larger adsorption capacity, the porosity is improved through the fibrous supporting material, the particle dust adsorption rate is improved, and the air purification efficiency is far higher than that of a traditional filter element.

Description

technical field [0001] The invention relates to the field of air filtration, in particular to a wall-flow honeycomb formaldehyde-removing air-conditioning filter element. Background technique [0002] With the rapid development of the world economy, industrial production and human life produce a large amount of PM such as 2.5 , NO x , SO x , VOCs and other air pollutants have caused a sharp decline in air quality in recent years. In order to improve the quality of the air in the environment, in the fields of indoor or in-vehicle air purification, dust prevention of electronic mechanical communication equipment, etc., people widely use various forms of air filter equipment to purify the air. In general, air purification and filtration equipment mainly captures and absorbs dust particles of different particle sizes and toxic and harmful gases in the air to achieve the purpose of purifying the air. In terms of purifying dust particles, traditional air purification and filtr...
