Polyester needled felt dust removal cloth bag is a fine fiber cloth with staggered fibers and uniform gap distribution by using non-woven needling process
The surface of the needled felt produced by polyester staple fiber and polyester twist yarn is treated by hot rolling, singeing or coating, so that its surface is flat and smooth, and it is not easy to be blocked by dust
This filter material has large porosity, good air permeability, wide range of uses, strong chemical stability, and can not only filter normal temperature gas, Moreover, it can filter corrosive gases containing acid and alkali, and can filter water and oil
It is a filter material in the fields of liquid-solid separation under normal temperature
Polyester needle felt, as a normal temperature filter material, has the advantages of good permeability, low equipment running resistance, high dust removal efficiency, easy ash removal and strong wear resistance
Generally, if the temperature in the dust collector box is less than 130 ℃, higher than the dew point temperature, the filtering wind speed ≤ 2
0m/min, and the relative humidity is small, you can safely use this filter material

Generally, if the median diameter of the filter medium is ≥ 325 mesh, its filtration efficiency can reach 99
9 ≈ 99
99%  The discharge concentration at the outlet of the dust collector can be less than 30mg/ cubic meter
Polyester needle felt can be widely used in metallurgy, building materials, chemical industry, smelting, mining, mineral processing, petrochemical, food and other fields of ventilation and dust removal, flue gas purification and micro material recovery
