Beschreibung
Zusammenfassung:	The utility model discloses a desulfurization and dust removal device which comprises an alkali recovery furnace, a dry dust collector, a circulating absorption reactor, a bag-type dust collector and a chimney, the alkali recovery furnace, the dry dust collector, the circulating absorption reactor and the bag-type dust collector are sequentially arranged in the flue gas purification flowing direction, a first outlet of the bag-type dust collector is connected with the chimney, and a second outlet of the bag-type dust collector is connected with the chimney. A second outlet of the bag-type dust collector is connected with an inlet of the circulating absorption reactor; and the circulating absorption reactor is provided with a process water inlet, an absorbent inlet and a fly ash inlet. In the desulfurization and dust removal device provided by the invention, the flue gas of the alkali furnace enters the dry dust remover through the flue after being discharged from the economizer, and the dust concentration of
