摘要：Based on laboratory research, the titanium-based honeycomb molding catalysts with MnOx/CeO2/V2O5 as the main active material were prepared, and a pilot scale study on medium/low temperature SCR denitration technology for ceramic kiln flue gas was carried out on a 5000 m3/h pilot scale equipment. The influences of flue gas flow, ammonia-nitrogen molar ratio and ammonia concentration on denitration efficiency were investigated. The result showed that the medium-low temperature SCR denitration technology had an excellent NOx removal efficiency. Under the conditions of the flue gas flow was 3000 m3/h, the ammonia-nitrogen molar ratio was 1.2:1, and the ammonia concentration was 25%, the NOx removal efficiency coulld reach 86%, and NOx emission concentration and ammonia escape amount were less than 40 mg/m3 and 1 mg/m3 in the flue gas, respectively. The technology can achieve deep reduction of NOx in ceramic kiln flue gas, and has a good application prospect.
