Desulfurizing Device

Abstract: A desulfurizing device (1) is provided with: a heat exchanger (21) which recovers heat from exhaust gas in a flow passage upstream portion (7), and which uses the recovered heat to heat the exhaust gas on the downstream side of a sprayer (11) in the direction of flow of the exhaust gas; a washing machine (26) which is disposed in the flow passage upstream portion (7) and which sprays a washing solution onto the heat exchanger (21); a discharge portion (28) which is provided in a bottom portion of the flow passage upstream portion (7) to discharge the washing solution; and a restricting member (31) which is disposed on the downstream side of the discharge portion (28) in the direction of flow of the gas and on the upstream side of the position of a boundary (8a) between an inflow portion (8) and a flow passage downstream portion (4), and which restricts the flow of the washing solution into the flow passage downstream portion (4). It is thus possible to suppress contamination by the heat exchanger washing solution of an absorption solution for desulfurization.
