Abstract
A method and apparatus for treating waste gas by irradiation with electron beams wherein an electron beam irradiation chamber for irradiation with electron beams from an electron beam accelerator is provided in the communication with a main duct containing waste gas. A part of the waste gas to be treated is introduced into the electron beam irradiation chamber where the part of the waste gas is irradiated with electron beams, thereby to form active species such as O and OH radicals. The waste gas having the active species formed therein is fed into the waste gas main duct by means of a feeding device and is dispersed into and mixed with the waste gas flowing through the main duct by means of a dispersing device, thereby changing noxious (gas) ingredients in the waste gas into the form of a mist or dust by the action of the active species. The mist or dust is captured by means of a capturing device, for example, a dust collector.
