Ordinary filter materials include traditional needle punched felt, woven filter materials, etc.
The working principle is the so-called “depth filtration” technology, that is, through the collection of filter material fibers, a “primary dust layer” (i.e. powder cake) is first formed on the surface of the filter material, and then this layer of powder cake is used to filter subsequent dust. dust.
In the early stage of reuse, due to the large gaps in the filter material itself, some dust will pass through the filter material and be emitted. Only when the powder cake is formed, the filtration process really begins. After continued use, the dust on the surface of the filter material will gradually penetrate into In the filter material, the gaps in the filter material will be blocked, which will continuously increase the operating resistance of the equipment until the filter must be replaced.
