3D (Three-dimensional) structural functional composite air purification filter element

Abstract

The invention provides a 3D (Three-dimensional) structural functional composite air purification filter element. The filter element is of a three-layer structure, namely, a filtering layer, an adsorption layer and a sterilizing layer which are arranged in sequence; material adopted includes non-woven fabrics, active carbon fibers and nano-silver non-woven fabrics. According to the 3D structural functional composite air purification filter element, the adopted structural functional non-woven fabrics show obvious adsorption to suspended particles and PM2.5 (Particulate Matter 2.5); the active carbon fibers are clamped between the two non-woven fabrics layers, so as to solve the problem that small granules easily leak while the granular adsorbing materials are adopted; nano-silver added on the non-woven fabrics solves the problem that a traditional air purification filter element has no sterilization effect. Compared with the traditional air purification filter element, the 3D structural functional composite air purification filter element has the advantages that the problems of dregs, difficult cleaning and incapability of sterilization and disinfection of the existing air purification filter element are solved; in addition, the drag coefficient is small, the purification efficiency is high, the sound can be absorbed, the cleaning is easily carried out, the sterilization effect is achieved, and the mass is small.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a functional composite air purification filter element with a 3D structure. Background technique [0002] With the rapid economic development, environmental pollution is becoming more and more serious. At present, many cities in our country have experienced large-scale smog weather, which not only brings inconvenience to people's lives, but also seriously affects our health. [0003] People are in the indoor environment most of the time. In order to strengthen the control of indoor air pollution, the use of air purifiers is becoming more and more common. Most of the purification equipment currently on the market can filter the air entering the room, but they do not have the function of sterilization and disinfection, and these products basically use granular adsorption materials to filter the air. Activated carbon particles have a saturated adsorption state, and small activated ...
