<p>PURPOSE:To irradiate electron rays effectively and to minimize the residence, the counterflow and the channelling of exhaust gas by a method wherein the flow rate of the exhaust gas containing SOx and NOx is reduced, the direction of the flow is adjusted, the speed of the flow is increased and the exhaust gas is introduced into an irradiation container. CONSTITUTION:The rectilinear side wall 4 of an exhaust gas flow relaxing chamber 1 is positioned at an angle of about 15 degrees to the direction of the flow of the exhaust gas, and widened from the inlet towards the interior. The side wall 4 is connected tangentially to a circular side wall 6 surrounding a rotating symmetry region 5. The exhaust gas to be treated flows from the left side in the horizontal direction into the gas flow relaxing chamber 1, and the speed of the gas is reduced. Then the exhaust gas is guided by a cross baffle plate 8 and a rectifier corn 9, ascends in the perpendicular direction, and flows into a gas flow acceleration adjusting part 2 where the speed of the exhaust gas is increased. The exhaust gas reaches an irradiation container positioned at the upper part, and is exposed to the dose irradiated by a plurality of electron ray accelerators 10, thereby the desired treatment of the exhaust gas can be carried out.</p> |
