Coated non-woven dust filter cylinder

Product details

Liffert coated non-woven dust filter is suitable for dry dust removal device, it is suitable for catching fine, dry non-fiber dust. The filter cylinder is made of textile cloth or non-textile felt, and the dust containing gas is filtered by the filtering effect of fiber fabric. When the dust containing gas enters the filter cylinder, the dust with large particles and heavy ratio settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is blocked and the gas is purified. General new filter material dust removal efficiency is not high enough. Filter material used for a period of time, due to screening, collision, retention, diffusion, electrostatic and other effects, the surface of the bag accumulated a layer of dust, this layer of dust is called the first layer, in the process of movement after this, the first layer became the main filter layer of the filter material, relying on the role of the first layer, larger mesh filter material can also obtain higher filtration efficiency. With the accumulation of dust on the surface of the filter material, the efficiency and resistance of the dust collector are increased accordingly. When the pressure difference between the two sides of the filter material is very large, some of the fine dust particles have been attached to the filter material are squeezed, so that the efficiency of the dust collector is reduced.

Performance characteristics

1. The filtration area increases by 3-5 times, and the filtration wind speed decreases greatly.

2. dust removal rate increased to 99.99%.

3. the length of the filter cylinder is short, there is a large excess space, conducive to dust settlement.

4. The life of the filter cylinder is prolonged.

5. All Wenzi tubes and cage racks are exempted.

6. the filter element is short and few, easy to install (top load), easy to repair and replace.

Technical parameter

1.The internal and external screen and the internal filter material use the international advanced automatic spiral casting machine glue fixing technology (or fastening belt fixing), to ensure that the filter cylinder processing air volume, filter area uniform for electromagnetic pulse valve back blowing ash.

2. filter material from domestic, imported coated polyester non-woven fabric (can do oil proof, waterproof, anti-static, flame retardant treatment) polyvinegar long fiber filter paper, glass fiber filter material using international advanced wide Fu discount technology, uniform gap.

3. The internal and external support protection skeleton adopts more than 5mm high strength, good anticorrosion performance punching stainless steel plate, large support force can prevent the filter cylinder blowing blow blow sucking flat.

4.The connection between the filter cylinder and the slide plate is sealed with low hardness and high strength foam sealing rubber ring to ensure no dust leakage, filtering accuracy can reach 99.9%.

5.Easy installation and maintenance, long service life.

6.The end cover of the filter cylinder is made of rust-proof steel plate more than 8mm thick (not easy to deformation). The adhesive of the end cover and the filter material is bonded by special polyurethane foam adhesive (to ensure that the end cover and the filter material are tightly connected without gaps).
