<p>PURPOSE:To restrain the amount of leak NH3 to be lower by introducing the gas contg. NOX, SOX into a radiant ray irradiation zone, collecting the formed by-products by a dry type electrostatic precipitator, and treating the exhaust gas by a wet type electrostatic precipitator. CONSTITUTION:The gas contg. NOX, SOX sent from a boiler facilities 1 is flowed through a heat exchanger 19 and added with NH3 through a flow rate adjusting valve 6 and introduced to a reactor 7 in which electron rays are radiated from an electron ray generator 9, and SOX, NOX are changed into by-products of ammonium sulfate and ammonium nitrate. These powders are recovered by the dry type electrostatic precipitator 17, and the exhaust gas is introduced to the wet type electrostatic precipitator 18 in which unreacted NH3, SOX, NOX are absorbed and removed by an absorbent liquid 22, and the gas is discharged through the heat exchanger 19.</p> |
