Efficient low wind resistance filter element and preparation method thereof

Abstract

The invention provides an efficient low wind resistance filter element and a preparation method thereof. The efficient low wind resistance filter element comprises a filter element body. The filter element body comprises a filter paper layer and a honeycomb filter layer. The filter paper layer comprises an anti-bacterial layer and a melt-blown electrostatic electret layer connected with the anti-bacterial layer. The honeycomb filter layer is arranged on one side of the anti-bacterial layer deviated from the melt-blown electrostatic electret layer. The honeycomb filter layer comprises a honeycomb support frame and a filter material. The honeycomb support frame comprises a storage unit arranged in a honeycomb shape. The filter material fills the storage unit. The anti-bacterial layer, the melt-blown electrostatic electret layer and the honeycomb filter layer are combined to be applied, functions of a filtering device are greatly enriched, and the requirements of filtering out particulate matter and harmful chemical substances are met.

Description

technical field [0001] The present invention relates to the technical field of air filtration equipment, and more particularly, to a high-efficiency and low-wind resistance filter element and a preparation method thereof. Background technique [0002] Air is one of the most precious resources in nature, but with the development of modern industry, the acceleration of urbanization, the relative concentration of population and the development of transportation, the atmosphere has been seriously polluted. [0003] With the continuous improvement of people's living standards, automobiles are gradually popularized in the domestic market, the increase of automobile exhaust gas and the increasingly severe environment make car owners pay more and more attention to the harm of PM2.5 fine particles to the human body. In addition, chemical substances released from the car interior, such as formaldehyde, benzene, TVOC, bromine, etc., also permeate the air; in addition, the harmful subst...

AI Technical Summary

Problems solved by technology

[0006] However, the existing filtering device has a single structure, which often cannot meet the requirements of filtering particulate matter and harmful chemical substances at the same time

[0007] Furthermore, due to the structural defects of the existing filtering devices, there are generally problems of large wind resistance and low filtering accuracy, which cannot play a good role in purifying the air.
