Multi-pollutants simultaneous removal from flue gas

The multi-stages humidifier semi-dry flue gas cleaning technology,the CRS plasma flue gas cleaning technology and oxidative additive flue gas cleaning technology were investigated for multi-pollutants removal.The semi-dry flue gas cleaning technology using multi-stages humidifier and additive can improve oxidation and absorption,and it can achieve high multi-pollutants removal efficiency.The CRS discharge can produce many OH radicals that promote NO oxidation.Combining NaOH absorption can achieve high deSO2 and deNOx efficiencies.It is fit for the reconstruction of primary wet flue gas desulfurization(WFGD).In addition,using NaClO2 as additive in the absorbent of WFGD can obtain very high removal efficiency of SO2 and NOx.
