In order to further achieve ultra-low emission of industrial flue gas pollutants, the characteristics of the 3D graded Catalytic Ceramic-fiber Filter, process flow and the key design parameters of the glass furnace pilot platform were analyzed. The results show that the integrated technology for flue gas pollutant removal with 3D graded Catalytic Ceramic-fiber Filter as the core had the characteristics of short process flow, low operating cost and long service life. The outlet emission concentrations of flue gas reached SO2<10 mg/m3, dust <3 mg/m3and NOX<23 mg/m3. This study could provide technical support for the treatment of industrial flue gas to reach ultra-low emission.
