To provide a vessel exhaust gas scrubber capable of adapting a dry type combustion, with a smaller back pressure, not easily damaging an electric power system of a vessel, small type and with easy installation.SOLUTION: A scrubber includes a columnar tower body 1 and a vacuum smoke progression throat unit 8 is arranged penetrating an attachment base 10 at a bottom end of the tower body 1. A flue gas lower distribution umbrella 7 and a flue gas upper distribution umbrella 6 are erected in order on a top end of the vacuum smoke progression throat unit 8, a preliminary cooling device 5 is installed above the flue gas upper distribution umbrella 6, a spray device 4 and a mist eliminator 3 are arranged above the preliminary cooling device 5, and a cleansing devices 2 are arranged on both top and bottom ends of the mist eliminator 3. An operation method for the scrubber includes two processes of desulfurization and dry type combustion.SELECTED DRAWING: Figure 4

    【課題】乾式燃焼に対応可能で、背圧がより小さく、船舶の電力系統を損傷しにくく、小型で設置が容易な船舶排ガス洗浄塔を提供する。【解決手段】洗浄塔は、円柱状の塔本体1を含み、塔本体1の下端の取付ベース10上には、真空煙進入スロート部8が貫通して配置される。真空煙進入スロート部8の上端には、煙道ガス下分布傘7及び煙道ガス上分布傘6が順に架設され、煙道ガス上分布傘6の上方には予冷装置5が配置され、予冷装置5の上方には、スプレー装置4及びミスト除去器3が配置され、ミスト除去器3の上下の両端には洗浄装置2が配置される。上記洗浄塔の作動方法は、脱硫と乾式燃焼の2つのプロセスを含む。【選択図】図4
