Abstract

Large amount acid mists will be produced by the technology of Wet flue gas desulphurization (WFGD) and selective catalytic reduction (SCR) produce in the coal-fired power plant, which will cause serious corrosion of pipeline and air pollution. Experiment and pilot test efficiencies of removing acid mist from WFGD were conducted using wet electrostatic precipitators (WESP) in this work. The effect of voltage, stay time and inlet concentration on the acid mist removal efficiency were studied. It was observed that the efficiency showed a quick rise tendency with the voltage, stay time and inlet concentration, slower than before after 40 kV, 1.6s and 170mg/m³, respectively. High performance of the WESP had been indicated by the experiment and pilot test results for acid mists control.
