Innovative filters made of polyoxadiazole fibers for industrial gas and dust emissions treatment

Abstract

Practicability of modern high thermal resistant polyoxadiazole fibers in the production of filtration textile materials for gas treatment stations is shown. Thermogravimetric researches proved high thermal resistance (up to 400℃) of filtration materials based on arselone fiber in thermal-oxidative atmosphere. Chemical composition of gas–dust, detained by textile bag filters on gas treatment stations of ferro-alloy plants, is examined. Efficiency of arselone textile material is analyzed in order to extract compounds of Cd, Pb, Mn, Zn, Cu, Cr, Al, Fe, Ca, and Mg from gas–dust.
