여과재 표면처리 방식에 따른 백필터의 탈진 및 먼지배출 특성 Characteristics of Filter Cleaning and Dust Emission of Bag Filters Made of Filter Media Prepared by Different Surface Treatment Methods Abstract This study was conducted to investigate the effect of surface treatment of filter media on the performance of bag filters. To this end, four bag filters were prepared using the different filter media made by four different surface treatment methods. Both surface and cross-sectional structures of each filter medium were examined, and the basic filtration properties of the filter media were tested. Based on the test results of the filter media, the cleaning and dust emission performance of each bag filter was evaluated using a bag filter test unit, followed by repeated filtration-cleaning cycles under dust loading conditions. As a result, the bag filters made of calendered and singed filter media with low pressure drop had cleaning intervals 3 times longer than bag filters made of membrane-laminated media. The singed filter bag, whose medium has a very porous inner structure, showed a very high concentration of dust emission which is 10 times higher than those of other bags. In addition, for the membrane-coated filter media, the pore structure of the membrane greatly affected the pressure loss of the filter media and the cleaning performance of bag filters. Among the filters tested in this work, the bag filter made of the calendered filter medium showed the best performance in terms of cleaning interval and dust emission due to the characteristics of surface and cross-sectional structure of the medium.
