Why does the PPS dust filter bag have corrosion?
Apr 13 , 2023
According to the analysis of the corrosion results of the PPS filter bag, there are three main sources of corrosion: oxidation, sulfur trioxide and nitrogen dioxide. 1. S—H2SO4 S in the flue gas forms SO2 and then becomes SO3 by oxidation. In the presence of water vapor, sulfurous acid vapor and sulfuric acid vapor or aerosol will be formed and condensed on the PPS filter bag to form dilute ...
