The present invention adds ammonia to the exhaust gas containing sulfur oxides (SO X ) and / or nitrogen oxides (NO X ) and then irradiates an electron beam to remove the sulfur oxides and / or nitrogen oxides from the gas. In the method,n n n An ammonia gas is uniformly mixed with air, and then the gas mixture and water are homogeneously mixed with a gas and a liquid, followed by spray injection into a reactor. According to the present invention, even when the temperature of the exhaust gas at the outlet of the reactor is relatively high, a high desulfurization rate is obtained, and the concentration of ammonium sulfamate in the by-products is remarkably reduced. |
