Abstract
An exhaust gas processing device preheats processing target exhaust gas in the presence of moisture with heat from at least either an electric heater or a heat exchanger and subsequently thermally decomposes the exhaust gas with an atmospheric pressure plasma. A device main body has a heating decomposition chamber therein. A plasma generator is installed at a top surface portion of the device main body. A reactor has a cylindrical shape and is installed within the device main body such that an upper end opening thereof is directed toward a plasma emission port of the plasma generator. A moisture supply unit is provided at an inlet side of the device main body. At least either the electric heater or the heat exchanger is disposed in a first space.
