| 摘要 |
The invention provides a flue gas processing apparatus including a catalyst unit (6) formed of at least one activated carbon fiber board (20), and water-supply means (7) for supplying, to the catalyst unit (6), water for forming sulfuric acid, the catalyst unit (6) being provided in the apparatus in the form of a tower (4) through which a discharge gas containing sulfur oxide passes, the water-supply means (7) being provided above the catalyst unit (6) or in an upper section of the unit (6) and in the apparatus in the form of a tower (4), wherein the activated carbon fiber board (20) provided in the catalyst unit is formed by alternatingly juxtaposing one or more plate-like activated carbon fiber sheets (21) and one or more corrugated activated carbon fiber sheets (22) so as to provide vertically extending conduits (15), and the flue gas processing apparatus includes pressurizing means (3) for applying pressure to the discharge gas, to thereby cause the gas to pass through the conduits (15) of the catalyst unit (6). Since pressure-elevated discharge gas passes through the catalyst unit (6), desulfurization is promoted. Through provision of holes (18) which link adjacent conduits (15), even flow of water and discharge gas in the activated carbon fiber board (20) can be attained, thereby promoting reaction.
