<p>PURPOSE:To perform the continuous dry treatment of an exhaust gas due to the irradiation of an electron beam without the loss of energy by irradiating the electron beam which is irradiated through a small hole provided to a pipe wall of a duct for transporting the exhaust gas to the exhaust gas while scanning it in the inside of the duct. CONSTITUTION:In a purifying apparatus for an exhaust gas generated by the combustion of fuel in a power plant or the like, after the electron beam irradiated from an electron beam accelerator 1' is irradiated in the specified direction through a small hole 6 provided to a duct 3' of the exhaust gas, it is scanned within a range of necessary scanning angle theta with a scanner 7 provided to the inside of the duct and irradiated to the exhaust gas. SO2 and NOX incorporated in the exhaust gas are made to dust or a mist with the irradiation of the electron beam and recovered with a dust collector or the like. Still more the inner pressure may be regulated with a suction pipe 9. Since a window foil is not necessarily stretched on an incident window by irradiating the electron beam through the small hole, the loss of energy is not caused and this apparatus is favorable in the industrial practice.</p> |
