Technical Field
The utility model relates to an environmental protection equipment technical field, more specifically say, relate to a filter layer and air purification device for air purification device.
Background
Pollutants in the air mainly consist of two forms, namely particles with large shapes such as dust, bacteria, mould and the like, the molecular structure of the particles is complex, and the particles are formed by combining a plurality of different substances or components, and the size of the particles is about one hundredth micron to hundreds of microns; the first is chemical molecules such as gas, odor, volatile organic chemicals and the like, the chemical structure of the material is simple, the material is composed of a plurality of chemical elements, and the material is very fine and only has the size from angstrom to nanometer.
Both types of contaminants are typically treated by filtration using different techniques. Conventional useful filter paper, even high efficiency filter paper (HEPAFilter), filters contaminated air; the dust collector also utilizes the electrostatic dust collection generated by high voltage or the method of releasing negative ions to make dust particles suspended in the air carry negative charges and then gather at the neutral or positive charge; active carbon, molecular sieve and zeolite are used as filtering materials, or ozone, oxidant and ultraviolet lamp are used to perform oxidation catalytic decomposition on pollutants by matching with photocatalyst or different catalytic catalysts. Each of these filtration methods has characteristics and performance.
Air purifiers on the market often use more than one air purification technology and filtration method for different pollutants in the air. The filter element arrangement method is usually that the filter elements of one layer are arranged in parallel, and only one air suction fan or air blower is arranged to drive the air flow to flow from the upstream to the downstream. Different filter elements have different physical and chemical characteristics, such as a filtering mode, an adsorption mode and an ionization mode; some filter elements have larger wind resistance, some filter elements have smaller wind resistance, and some filter elements have no wind resistance. Because the air has pollutants with different concentrations and pollutants with different sources, the air purification becomes a complicated subject. In the traditional filter element arrangement mode, certain post-positioned filter layers have shorter service life and even are damaged because the pre-positioned filter layers do not effectively treat pollutants, or accumulated pollutants are blown out, but the pollutants in the environment are increased.
