Multifunctional air purification filter screen

Abstract

The invention discloses a multifunctional air purification filter screen, which comprises a primary filter module, an HEPA filter module, and a gas adsorption and catalytic degradation module. The multi-module structures are connected and fixed into an integral filter screen from the outside in, the filter screen can achieve effective interception of fine particulate matters (PM2.5), bacteria, viruses and other particulate pollutants and thorough decomposition and purification of formaldehyde, ozone, toluene and other gaseous pollutants, also has deodorization, bacteriostasis and sterilization effects, is a multifunctional air purification filter screen integrating air filtration, purification, antibacterial efficacy, etc. With the characteristics of small wind resistance, long service life and good stability, the multifunctional air purification filter screen provided by the invention has great application prospects in air purifiers, central ventilation systems and other air purification devices, also is low in cost, and can realize large-scale continuous production.

Description

technical field [0001] The invention belongs to the field of air filtration, and in particular relates to a multifunctional air purification filter net. Background technique [0002] In recent years, with the development of rapid urbanization and industrialization, air pollution has become one of the major environmental problems in my country, and even southern regions with better air conditions are frequently attacked by smog. The main pollutants in smog are fine particulate matter (PM 2.5 ), referring to particles with an aerodynamic equivalent diameter ≤ 2.5 μm. It has been socially recognized that smog can induce respiratory diseases, cause cardiovascular and cerebrovascular diseases, and increase the risk of cancer. When smog occurs, the indoor air cannot escape PM 2.5 s damage. According to the research report of Tsinghua University, when the concentration of outdoor PM2. 2.5 There is a proportional relationship of 0.65-0.80 in the concentration. This is because ...

Problems solved by technology

At the same time, the function of the filter is single. Most of the filters can only filter particulate matter. Few filters can purify formaldehyde, toluene, ozone and other gaseous pollutants at the same time, and have antibacterial and antibacterial functions. less

In addition, the existing air filter is a single whole. Once some parts are dirty or some functions do not work, they can only be removed and replaced as a whole. This will not only cause waste of resources, but also increase the cost of use.
