摘要： A ship desulfurization device for desulfurizing exhaust gas discharged from an exhaust gas generation device mounted to a ship includes: an absorber including an absorber body unit defining an interior space having a longitudinal direction and having an exhaust gas introducing port formed on an end portion of the absorber body unit with respect to the longitudinal direction, the exhaust gas introducing port being in communication with the interior space; and an exhaust gas introducing device for introducing exhaust gas discharged from the exhaust gas generation device to the absorber body unit. When L is a maximum length of the interior space of the absorber body unit with respect to the longitudinal direction, and W is a maximum width of the interior space of the absorber body unit with respect to a lateral direction that is orthogonal to the longitudinal direction, a ratio (W:L) of the maximum width W to the maximum length L is within a range of 1:over 1.1 and 1:6.0 or under 6.0.

摘要： Provided is a desulfurization device that allows for the easy and accurate disposition of a spray pipe inside an absorption tower. Provided is a desulfurization device including: an absorption tower (10); and a spray pipe (20) disposed inside the absorption tower (10). The spray pipe (20) includes: a cylindrical pipe portion (21), the leading end of which is closed; and an attachment flange (24) attached to the pipe portion (21). The absorption tower (10) includes: an opening hole (14e) opening toward the side; and a flange (14a) disposed around the opening hole (14e). The attachment flange (24) and the flange (14a) are detachably attached.
