<P>PROBLEM TO BE SOLVED: To provide an exhaust gas-treating device which restrains the amount of leaked NH<SB POS="POST">3</SB>from increasing while sufficiently removing NOx. <P>SOLUTION: The exhaust gas-treating device 100 includes an adsorption tower 10 and an NH<SB POS="POST">3</SB>-removing tower 20. The adsorption tower 10, which is filled with a carbonaceous adsorbent, removes NOx in an exhaust gas R, to which NH<SB POS="POST">3</SB>is fed, by a reductive reaction due to a catalytic effect of the carbonaceous adsorbent and makes the carbonaceous adsorbent adsorb SO<SB POS="POST">2</SB>in the exhaust gas R to remove it. The NH<SB POS="POST">3</SB>-removing tower 20, which is filled with a carbonaceous adsorbent, makes the carbonaceous adsorbent adsorb NH<SB POS="POST">3</SB>in the exhaust gas R discharged from the adsorption tower 10 to remove it. In this case, the adsorption tower 10 has a front chamber 12a, an intermediate chamber 12b and a back chamber 12c which are each provided along an exhaust gas flow channel so that the exhaust gas R may sequentially flow, and the carbonaceous adsorbent, which is charged in the back chamber 12c, is moved and fed to the NH<SB POS="POST">3</SB>-removing tower 20. <P>COPYRIGHT: (C)2012,JPO&INPIT |
