DESULFURIZATION/DENITRIFICATION DEVICE OF TAIL GAS

摘要

PPROBLEM TO BE SOLVED: To make it possible to collect the dust of an adsorbent while inhibiting its spout. PSOLUTION: This device comprises a desulfurization/denitrification column body 20 and an adsorbent cutting device 30. In addition, the device is equipped with an inlet louver 26 and an outlet louver 27 for forming a movable adsorbent-filled layer which moves downward inside a desulfurization column 20, and a constricted part 41 which is arranged between the column body 20 and the cutting device 30 and equipped with a side plate 41b which is inclined in the way that the space gradually diminishes toward the cutting device 30 side. Further, a first partitioning plate 43 is arranged inside the constricted part 41, and a second partitioning plate 44 is arranged extending in the inclined direction of the side plate 41b, apart by a specified interval above the side plate 41b from the lower end of the outlet louver 27. Besides, a gap is arranged between the lower end part of the outlet louver 27 and the side plate 41b of the constricted part 41. PCOPYRIGHT: (C)2009,JPO&INPIT
