Abstract

Abstract

To address the need for synergistic control of multiple pollutants and ultra-low emissions from glass furnace flue gas， this study developed an integrated purification process using H4150-type ceramic fiber catalytic filter tubes. A pilot-scale system was implemented at a flat glass factory in Henan Province. This study systematically investigated the relationship between filtration velocity and filtration resistance and evaluated the effects of operational parameters （reaction temperature， filtration velocity， and SO₂ concentration） on the denitrification performance of the catalytic filter tubes. The results indicated that the integrated system operated stably and the operating pressure drop increased linearly with filtration velocity. At a filtration velocity of 0.8 m/min and a reaction temperature of 300 ℃， the operating pressure drop was 875 Pa， with NO_x emission concentrations below 40 mg/Nm³ （denitrification efficiency ≥ 98%）. Additionally， the particulate matter emission concentration was less than 5 mg/Nm³， and ammonia slip was maintained below 8 mg/Nm³， demonstrating remarkable synergistic control of multiple pollutants. In particular， the system maintained stable catalytic activity after continuous operation， and even under severe conditions with an SO₂ concentration as high as 1100 mg/Nm³， the denitrification efficiency of the catalytic tubes remained above 97%， exhibiting outstanding sulfur resistance. This process offers comprehensive advantages， including high purification efficiency， a small footprint， and low operating cost， providing critical technical support for upgrading existing glass furnace flue gas purification systems to achieve ultra-low emissions.
