Abstract—Coal-fired power plants are big contributors to air plants is plex, , which contains not only dust, N2,
pollution and particle pollution is one of the most dangerous air CO2 but also O2, SOx, NOx and other corrosive gases, and its
pollutants. In order to solve the problem, fabric filters are widely temperature could reaches to 160-200℃. Due to the above
