Acrylic Medium Temperature Needle—punched Filter Felt Bag

　　Acrylic Medium Temperature Needle—punched Filter Felt Bag

　　Using non—woven needle—punching technology, the surface of line fiber cloth with interlaced strong fibers and uniform void distribution is smoothed by hot rolling and singeing treatment, which is not easy to be blocked by dust. The filter material has large void, good permeability and strong chemical stability. It can not only filter atmospheric temperature gas, but also medium temperature gas. Ills the ideal choice of filter materials under acid—alkali cofrosive gas condition.

　　The filter bag is the key component to determine the dust removal efficiency and working temperature of the bag dust collector, and the cost of replacing the filter bag is the main maintenance cost of the bag dust collector. Therefore, the working life of the filter bag is related to the operation state and cost of the dust collector, so it is particularly important to select the appropriate filter material and design the reasonable structure.

　　The selection of filter material should be considered according to the temperature, humidity and chemical characteristics of the gas, the size, weight, shape, ponderability of particles, dust concentration, filtration speed, ash cleaning mode, emission concentration and the working system of bag dust collector. In general, the pulse spray bag filter uses needle felt, the chamber back blowing bag dust collector or the mechanical vibration bag filter selects the woven cloth.
