摘要：

The flue gas multi-pollutants simultaneous removal is an inevitable trend in the field of flue gas purification. In our researches, the AC technology, the multi-stage humidifier semi-dry technology, the CRS plasma technology and the additive oxidization technology were investigated. The V(2)O(5)/AC is highly active for the SCR reaction at low temperature. NO(x) conversion increased with increasing NO(2)/NO(x) ratio and the catalyst can achieved the highest activity at a temperature as low as 150 degrees C. The semi-dry flue gas cleaning technology can achieve high multi-pollutants removal efficiency through the multistage humidification and the improving additives. The removal efficiencies of SO(2), NO(x) and Hg can reach 95%, 41% and 73% respectively in the practice project. The alkali solution absorption basing on the CRS oxidization can achieve high deSO(2) and deNO(x) removal efficiencies. In addition, the additive oxidation technology using NaClO(2) can obtain the removal efficiency of near 100% SO(2) and above 80% NO(x).
