Design of Filter Bag Media with High Collection Efficiency

초록

By the equipment in a nonwoven pilot plant, the various filter bag media were prepared, which was coupled with needle punching and thermal bonding combination processes. The prepared filter media were evaluated according to the reliability assessment standard for the filter bag media of environmental cleaning dust collector (RS K 0001). The air permeability of the filter bag media with nano-sized web was largely reduced as compared with the control medium. From the evaluation of filtration test, it was found that the filter medium with nano-sized web showed more stable filtration behavior and higher collection efficiency than those of the control medium.
