To achieve stable and high accurate desulfurization in a seawater desulfurization device.SOLUTION: A seawater desulfurization device comprises: an absorption tower 11 which has an exhaust gas introduction part 22 and an exhaust gas lead-out part 23 for exhaust gas G, and in which an exhaust gas flow channel 24 is provided along a vertical direction; and a spraying device 12 which sprays sea water S vertically downward to the exhaust gas G which flows vertically upward in the exhaust gas flow channel 24. The spraying device 12 has: plural first pressure water spraying nozzles 31 which are juxtaposed in the exhaust gas flow channel 24, and pressurize and spray the sea water S; a sea water supply pump 26 which can supply the sea water S to the plural first pressure water spraying nozzles 31, and can adjust a spray area of the sea water S by the first pressure water spraying nozzle 31; and plural second pressure water spraying nozzles 32 which pressurize and spray sea water to an area of the exhaust flow channel 24 where the plural first pressure water spraying nozzle 31 cannot spray the sea water S.SELECTED DRAWING: Figure 2

    【課題】海水脱硫装置において、脱硫処理の安定化及び高精度化を図る。【解決手段】排ガスGの排ガス導入部22と排ガス導出部23を有して内部に鉛直方向に沿う排ガス流路24が設けられる吸収塔11と、排ガス流路24を鉛直方向の上方に向けて流れる排ガスGに対して鉛直方向の下方に向けて海水Sを散布する散布装置12とを備え、散布装置12は、排ガス流路24に水平方向に並列されて海水Sを加圧して噴射する複数の第1加圧散水ノズル31と、複数の第1加圧散水ノズル31に海水Sを供給可能であると共に第1加圧散水ノズル31による海水Sの散布領域を調整可能な海水供給ポンプ26と、複数の第1加圧散水ノズル31が海水Sを散布できない排ガス流路24の領域に海水とを加圧して噴射する複数の第2加圧散水ノズル32とを有する。【選択図】図2
