1. The depth filtration media such relatively loose, the gap between fibers is large, such as ordinary polyester needle felt, voids have 20 ~ 100 μm. When the average particle size of dust at 1 μm, during the filtration operation, a portion of the fine particles will enter the filter inside the residence down, the other part will pass through the filter to escape out. Most of the dust attached to the filter surface, forming a layer of filter layer, the filter layer of dust in the dust stream will filter down. Filter fine particles into the interior, will make resistance increases, filter harden until retirement. This filtering is generally called deep bed filtration. 2. The contact surface filtration loose filter dusty gas side, an adhesive layer of microporous film, the gap between the fibers, which is just 0.1 ~ 0.2 μm, when the average particle size of the dust is still 1 μm, filtering operation Almost all of the powder will be blocked on the surface of the microporous film, fine dust can not enter inside the filter, this filter mode is generally called surface filtration. Surface filter is the ideal filter technology, which can further improve the collection efficiency, reduce the pressure loss of filter media, dust removal system saves a lot of power consumption. If the filter is very thin fibers, through a special process, both to maintain a certain degree of permeability, it can narrow the gap between the fibers. This filter, although not at the surface Fumo, but fine dust particles is also difficult to enter the filter inside. This lack of laminating the media, can also be surface filtration operations. Production cartridge filter, there is the media and non-media Fumo Fumo, can be surface filtration operation, depending on the choice of the media may be.
