摘要： The present invention relates to an electron beam-irradiating reaction apparatus for irradiating a desired object to be treated, such as an exhaust gas, with an electron beam. Conventionally, a scanning tube of an electron beam irradiation device and a reaction device-for receiving the electron beam are rigidly connected. Therefore, excessive stress is applied to a connecting portion between the scanning tube and the reaction device and not only leakage of gas from the connecting portion, but also breakage of a metal window foil provided at an end portion of the scanning tube are likely to occur. In the present invention, to solve such problems, a flexible hermetic sealing member 23 is provided between a portion around the end portion of the scanning tube 12 and a peripheral edge 18a of an electron beam receiving window in a side wall of an electron beam reaction device 18.

摘要： The present invention relates to a flue gas treatment method and apparatus for removing sulfur oxides by injecting ammonia into flue gas containing sulfur oxides. In the flue gas treatment method for removing sulfur oxides contained in the flue gas using ammonia, the present invention is characterized in that ammonia is injected into the flue gas containing sulfur oxides to react sulfur oxides with ammonia to produce ammonium compounds containing ammonium sulfate, and after recovering the produced ammonium compounds from the flue gas, the flue gas is brought into contact with an absorption liquid to remove residual sulfur oxides and/or ammonia contained in the flue gas.

摘要： A method and apparatus for treating gas by irradiation with an electron beam. Flue gas discharged from a fuel combustion facility is treated with an electron beam to remove sulfur oxides and/or nitrogen oxides. Ammonia is added to the flue gas and the mixed gas is irradiated with an electron beam in a process vessel. A dust collector receives the gas and collects a by-product mainly composed of ammonium sulfate and/or ammonium nitrate which is produced by the reaction in the process vessel. A gas-contacting portion extending from the process vessel to the dust collector is cooled either wholly or partly, to a dew point of the gas or below.
