Abstract

PPS filter media is one of the best available filter media for dust collection in the coal-fired power plant, but the performance of PPS filter media is influenced by SO₂ in the flue gas. In this paper, effect of SO₂ on PPS filter media was studied. Through the analysis of mechanical performance, microscopic characteristics and chemical structure of PPS filter media, it is considered that PPS filter media has good corrosion resistance to SO₂, at the same time, SO₂ also has definite corrosive effect on the PPS filter media, and corrosion increases with the increase of SO₂ concentration and aging time. The temperature has accelerating effect on the corrosion.
