But CN108248343A, CN201410350Y all adopt the direct superposition of the planar multi-layer shape, the adsorption efficiency is low; At the same time, activated carbon particles are used, the adsorption efficiency is low, need to be replaced frequently, and the effect of removing the bacteria layer is limited
[0005] Carbon fiber paper is a functional paper with special properties produced by mixing carbon fiber or activated carbon fiber with other plant or non-plant fibers. It is mainly used in the gas diffusion layer of proton exchange membrane fuel cells. In the prior art, carbon fiber paper is rarely used in cars. Reports in the field of air purification

Abstract

The invention discloses an air purification filter element in a car, which comprises a filter layer bonded as a whole, a high-efficiency adsorption layer, a functional layer and a skeleton layer; the filter layer is a non-woven fabric loaded with formaldehyde adsorption resin; the high-efficiency adsorption The layer is carbon fiber paper; the functional layer is loaded with a fiber cloth of a metal catalyst, and the metal catalyst is TiO 2 , α‑MoO 2 1. One or more combinations of silver ion catalysts; the skeleton layer is a glass fiber filter screen. Due to the large pores formed by the accumulation of carbon fibers and the micropores formed by the surface activation of carbon fibers, carbon fiber paper can efficiently absorb volatile organic compounds, and at the same time avoid the agglomeration of activated carbon particles to reduce the service life; the functional layer loaded with metal catalysts can efficiently kill bacteria, viruses and other microorganisms The filter element has the beneficial effects of strong adsorption capacity, wide adsorption range and long service life.

Description

technical field [0001] The invention relates to an air purifier filter element, in particular to a high-efficiency car interior air purification filter element. Background technique [0002] With the sharp increase in the number of cars in my country and the continuous enhancement of consumers' health awareness, the air quality in cars is getting more and more attention from the whole society. The environment inside the car will affect the driving comfort, especially in a confined space, the car interior will continue to emit volatile organic compounds, some of which are carcinogenic or teratogenic, and will have a profound impact on the health of drivers and passengers. How to establish an efficient in-vehicle air quality control plan, reduce the emission of volatile and harmful substances in automotive products, and improve the in-vehicle air quality has become the focus of attention of industry companies. [0003] In the prior art, indoor air purifiers are mainly used to...
