DESULFURATION-DENITRATION APPARATUS FOR EXHAUST GAS

摘要

Intended is to make the recovery of adsorbent dust possible while preventing the injection. Provided is a desulfuration-denitration apparatus comprising a desulfuration-denitration tower body (20) and an adsorbent cutting device (30). An entrance louver (26) and an exit louver (27) are disposed in the desulfuration tower (20) so as to form an adsorbent charging moving layer moving downward therein. A throttle portion (41) having side plates (41b) inclined to reduce the spacing gradually toward the cutting device (30) is interposed between the tower body (20) and the cutting device (30). First partitions (43) are disposed in the throttle portion (41). A second partition (44) extending along the inclined direction of the side plates (41b) is spaced at a predetermined distance from the lower end of the exit louver (27) over the side plates (41b). A spacing is kept between the lower end portion of the exit louver (27) and the side plates (41b) of the throttle portion (41).
