| 英文摘要 | In order to solve the SO2 poisoning problem of the existing Mn-based catalytic filter bags, a catalytic filter bag based on V2O5-MoO3/TiO2 was prepared for the simultaneous removal of NOx and dust in the range of 180-260. The experimental results displayed that the double-layer filter bags had excellent denitration activity and SO2/H2O-resistant stability when the gas filter surface velocity was 0.2 m/min. The double-layer catalytic filter bags were used in the pilot-scale test of pure oxygen glass kiln, when the flue gas volume was about 2000-3000 m3/h, SO2 concentration in the range of 20-30 mg/m3, the water vapor content was 10%(vol) and NOx concentration in the range of 400-550 mg/m3, the NOx conversion reached 88.14%-95.06% from 170 to 210, and the good denitration performance of catalytic filter bags had been verified. After 1500 h of continuous operation, the activity showed a slight decay of about 5%. Under high-sulfur flue gas conditions (300-500 mg/m3) for 100 h continuous operation, the catalytic filter bag was found to be deactivated. SEM-EDS and XPS characterizations proved that the catalyst deactivation was due to the deposition of ammonium sulfate on the surface of the filter bag fiber and the part of active site is covered. 漏 2021, Editorial Board of CIESC Journal.
