Abstract: 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.

Abstract: A method for installing a spray pipe, including an insertion step of inserting a spray pipe from an opening portion, a positioning step of positioning the spray pipe such that an installation surface of a leg portion faces a supporting surface of a supporting portion, a provisional tightening step of provisionally tightening a first fastening portion to couple an attachment flange with the opening portion, an adjusting step of adjusting the height of the installation surface relative to the supporting surface such that an axis along which a pipe portion extends coincides with the horizontal plane, in the provisionally tightened state resulting from the provisional tightening step, a coupling step of coupling the leg portion to the supporting portion by means of a second fastening portion, after the adjusting step, and a final tightening step of performing a final tightening of the first fastening portion after the coupling step.

Abstract: 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.

Abstract: A water treatment tank includes: a tank body including a bottom surface extending in a horizontal direction; an overflow wall partitioning the inside of the tank body into an upstream tank into which treatment water having absorbed sulfur from an exhaust gas is introduced and a downstream tank into which the treatment water overflowing from the upstream tank is introduced to flow therein; and an inclined part that is provided between the bottom surface of the tank body and the overflow wall in the downstream tank and is inclined downward as it goes from the overflow wall toward a downstream side inside the downstream tank to be connected to the bottom surface of the tank body.

Abstract: A water treatment tank includes: a tank body including a bottom surface extending in a horizontal direction; and an overflow wall installed in the tank body to partition an inside space of the tank body into a seawater intake upstream tank into which treatment water having absorbed sulfur from an exhaust gas is introduced and a seawater intake downstream tank into which treatment water overflowing the seawater intake upstream tank is introduced to flow therein. The treatment water flowing into the seawater intake downstream tank is divided by the overflow wall in the width direction of the overflow wall so as to form a waterfall region and a non-waterfall region.
