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 exhaust gas is denitrified by a denitrification device not shown in the figure, and after being cooled by the exhaust 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...

Abstract

A kind of flue gas desulfurization device, by alternately stacking flat plate activated carbon fiber thin plates and corrugated wave plate activated carbon fiber thin plates, forming the state that the passage extends in the up and down direction, and constituting the activated carbon fiber layer of the catalyst layer (6) ( 20), and the activated carbon fiber layer (20) of the catalyst layer (6) is supplied by the water utilized for generating sulfuric acid by capillary penetration, and the minimum amount of water can be used to add moisture evenly to the activated carbon fiber layer (20) to remove sulfur oxides ( SOX), which can reduce the water used to remove sulfur oxides (SOX).

Description

[0001] This application is a divisional application, the application number of its parent application is: 02807664.8, the application date: 2002.10.16, the name of the invention: exhaust gas desulfurization device, exhaust gas desulfurization system and operation method of exhaust gas desulfurization device. technical field [0002] The present invention relates to the removal of sulfur oxides (SO4) in exhaust gases discharged from boilers, gas turbines, engines, incinerators, etc. that burn fuel such as coal and heavy oil. X ), the exhaust gas desulfurization device, the exhaust gas desulfurization equipment and the operation method of the exhaust gas desulfurization device. [0003] Furthermore, the present invention relates to a method for removing sulfur oxides (SO X ) desulfurization method. Background technique [0004] Contains disulfide in exhaust gas from thermal power generation equipment with boilers using fuel such as coal and heavy oil, chemical product manufac...
