Estimation of the particle penetration and the dust holding capacity of different surface-treated needle felts

Experimental investigation of deposition and removal of particles during gas filtration with various fabric filters

“…Such treatments result in less deposition inside the filter medium, leading to a more surface-based filtration operation [2]. This process improves the performance of the filter, prolonging the filtration period and reducing the pressure drop after cleaning [3].…”

“…The presence of the particulate matter in the surface pores of the filter after cleaning has a significant effect on particle penetration and the particle mass deposited after the cleaning process, increasing considerably the residual pressure drop and the filtration resistance [2,3]. Hence, better knowledge of the particle deposition process and adhesion forces in the cake would improve our understanding and control of gas filtration operations.…”

Experimental study of dust deposition in dynamic granular filters

“…Meanwhile, several researchers have reported their investigations on pressure drop, collection efficiency and porosity of dust cake during cake ltration in granular lters. [19][20][21] The effects of dust properties, granular material properties, and structures of the lter on dust cake formation and collection efficiency of the lter have been examined. Choi 22 concluded that the dust cake was compressed by former cake layers with drag forces of later-formed dust layers, which was based on the dust build up model proposed by Schmidt.…”

Extended PTFE fabrics used as high-temperature filter clothes: manufacturing technique and chemical stability evaluation

“…Filter media plays a significant role in any filtration systems (Wang & Ding, 2008). For industrial uses in particular environments, filter materials have to be heat resistant, chemical resistant, and dimensional stability as well as convenient use (Hoeflinger, Rud, & Mauschitz, 2007;Mauschitz, Koschutnig, & Hoeflinger, 2005;Park, Lee, Kim, Kim, & Jo, 2010;Rodrigues, Tieni, Gonçalves, & Aguiar, 2005;Wang, Yan, & Li, 2012). They can be applied as Food/Pharmaceutical (Pneumatic Conveying, Material Handling), Chemical (Industrial Wastewater, Paint/Pigments), and Combustion (Boiler, Coal Handling, Fly Ash Handling, Waste Incinerators).…”
