Embodiment Construction

[0083] In order to explain this invention in detail, it demonstrates based on drawing.

[0084] according to figure 1 An exhaust gas treatment system including the exhaust gas desulfurization device of Example 1 will be described.

[0085] Such as figure 1 As shown, for example, fuel f such as coal and heavy oil is burned in boiler 1 that generates steam in order to drive a steam turbine of an unshown thermal power plant. The exhaust gas from boiler 1 contains sulfur oxides (SO X ), the waste gas is denitrified by a denitrification device not shown in the figure, and after being cooled by the waste gas heater, dust is removed in the dust collector 2.

[0086] The dedusted exhaust gas is sent to the humidification cooling device 16 through the blower 3, and water (containing dilute sulfuric acid) is mixed in the humidification cooling device 16 to become the exhaust gas in a saturated steam state. At this time, smoke may be contained in the exhaust gas. The exhaust gas in ...

Abstract

The invention provides a flue gas desulfurization apparatus includes at least one activated carbon fiber board 20 provided in a catalyst unit 6, the board being formed by alternatingly juxtaposing one or more plate-like activated carbon fiber sheets and one or more corrugated activated carbon fiber sheets so as to provide vertically extending conduits, wherein water for producing sulfuric acid is supplied, through a capillary phenomenon, to the activated carbon fiber board 20 provided in the catalyst unit 6. The flue gas desulfurization apparatus attains removal of sulfur oxides (SOx) by adding a minimum required amount of water to the activated carbon fiber board 20 so as to attain uniform water distribution and can reduce the amount of water required for removing sulfur oxides (SOx).
