Filter core for environment-friendly type air purifier

Abstract

The invention discloses a filter core for an environment-friendly type air purifier, and belongs to the field of air purifiers. The filter core comprises a housing, a supporting layer, a preliminary filtering layer, a microfiltration layer and a nanofiltration layer; the supporting layer is used to support the housing structure; the preliminary filtering layer is used to intercept large-granule suspended matter in air; the microfiltration layer is used to separate micrometer-size particles in air, and comprises two micrometer fibrous layers both prepared from a chitosan solution through an electrostatic spinning technology, a micrometer fibrous filter membrane which is sandwiched between the two micrometer fibrous layers and is doped with a photocatalyst; and the nanofiltration layer is used to remove nanometer-level dust particles in air and also adsorb heavy metal ions and decompose organic harmful gases and inhibit bacteria, and is a nanometer fibrous layer prepared from a chitosan solution through an electrostatic spinning technology. According to the technical scheme, multi-layer structure design is employed, the material characteristics are ingeniously combined, and thus the filtering effect of the filter core is substantially optimized, and air purification effect is enhanced.

Description

technical field [0001] The invention relates to a filter core of an environment-friendly air purifier. Background technique [0002] The air contains a large number of pollutant particles, including dust of heavy metal ions, toxic chemicals, and some infectious microorganisms and viruses. At present, the filter materials commonly used in air purifier filter elements include glass fiber, metal fiber, ceramics, and common polymer materials. The environment is worse, and it does not have antivirus and sterilization effects. Moreover, it has great deficiencies in filtering submicron dust, especially in the purification of nanometer particles, so its efficiency needs to be improved. Contents of the invention [0003] In view of the above-mentioned technical deficiencies, the present invention provides a filter element of an environment-friendly air purifier, which has the characteristics of environmental protection, natural degradation, sterilization and antibacterial, and hi...
