Abstract:

For coal-fired power plant boiler flue gas desulfurization wastewater’s actual spraying proposed combination bag house dust while mercury removal process. Experimental study of the coal-fired boiler flue gas spraying chlorine ions and other halogens desulfurization wastewater modified fly ash flue gas mercury performance. Studies showed that desulfurization wastewater fly ash on chloride ion enhanced oxidation of elemental mercury, with the increase in the amount sprayed desulfurization wastewater, flue gas mercury capacity increased. Desulfurization wastewater add another halogen element can promote flue gas mercury performance, the effect of iodine was the most significant, followed by bromine. The desulfurization wastewater as a modified liquid sprayed into the flue modified fly ash, fly ash can improve mercury removal performance, eliminate the need for desulfurization wastewater treatment, cost savings, achieve desulfurization wastewater recycling.
