【Abstract】 The experiment of wet flue gas desulfurization by electric transfer was introduced that SO 2 can become negative ion by catching electron in the condition of discharge and the negative ion of SO 2 moves in the electric field to conduct the flue gas desulfurization combining corona discharge with wet water film. The simulated experiment were conducted to research the main factors affecting the electric transfer of SO 2 and the desulfurization efficiency such as simulated gas parameters, structure of the reactor and the characteristics of corona discharge, etc.. The results indicate that SO 2 has the ability of electric transfer in the corona discharging electric field. The desulfurization efficiency goes up with the increase of applied voltage, length of discharging area and input power. The desulfurization efficiency may be over 90?% under the test condition.更多还原
