High Temperature FMS Needle Felt for Filter Bag

The filter bag is a key part of the operation of the bag filter. Usually the cylindrical filter bag is suspended vertically in the dust collector. The fabric and design of the filter bag should be as efficient as possible for efficient filtration, easy dust removal and durability. In pulsed and air box type pulse dust collectors, dust is attached to the outer surface of the filter bag. When the dust-laden gas passes through the dust collector, the dust is trapped on the outer surface of the filter bag, and the clean gas passes through the filter material and enters the inside of the filter bag. The cage inside the filter bag is used to support the filter bag to prevent the filter bag from collapsing, and it helps to remove and redistribute the dust cake.

Product Description

Product Description

FMS filter bag is an effective and high temperature resistant, corrosion resistant, acid and alkali resistant and wear-resistant composite product. FMS is a new type of high temperature filter for the development of blast furnace gas dry cleaning. FMS filter material added P84 fiber on the basis of glass fiber needle felt, making the felt layer more compact, and the winding between fibers enhanced, which can be used to deal with higher filtering wind speed.P84 fiber is section 3 leaf type, to form a high coefficient of surface area, increasing the probability of dust, and the special section shape, the dust most concentrated to the surface of filter material, difficult to penetrate the filter material blocking space inside, reduce resistance and improve the filtering speed.
