摘要： A nozzle provided inside an absorption tower requires periodic maintenance because it degrades because of deformation caused by corrosion due to a liquid injected, wear of an injection port due to injection of a liquid at high-pressure, or the like. Normally, the nozzle and the absorption tower that includes therein a trunk tube that supplies a liquid to the nozzle, and the like are configured integrally. Therefore, if maintenance of the nozzle is to be performed, the entire absorption tower needs to be detached and dismantled temporarily from an exhaust gas processing apparatus. For this reason, the work is large-scale, and it has been difficult to make ready operators, the work time, the working space and the like. An exhaust gas processing apparatus is provided, the exhaust gas processing apparatus including: an absorption cylinder that absorbs a target substance in an exhaust gas by causing the exhaust gas to contact a liquid; an injection portion that injects the liquid into an inner space of the absorption cylinder through which the exhaust gas passes; a conduit: to which the injection portion is attached; that guides the liquid to the injection portion; and that is arranged inside the absorption cylinder; and a supply tube that supplies the liquid to the conduit, wherein the conduit has an uncoupling portion that allows uncoupling from the supply tube so that the conduit can be withdrawn to an outside along a flue that guides, to outside air, the exhaust gas that has passed through the absorption cylinder in a state where the injection portion remains attached.

摘要： An object of the present invention is to achieve stable operation by supplying an appropriate amount of seawater to a scrubber in such a manner that the sulfur oxide concentration in the exhaust gas after processing does not exceed a limit value, and to reduce the measurement frequency of the alkalinity. The amount-of-seawater control device for a scrubber includes: a minimum-amount-of-seawater converter (61) which calculates a minimum amount of seawater which is a minimum amount of seawater necessary for an absorption reaction of the sulfur oxide by the seawater, from an engine output and a sulfur content of fuel oil; an amount-of-seawater correction converter (68) which calculates a corrected amount of seawater which is an amount of seawater at which the sulfur oxide contained in the exhaust gas discharged from the scrubber is equal to or less than a set value; a summing element (69) which calculates a set amount of seawater by summing the minimum amount of seawater and the corrected amount of seawater; a pump control device (70) which implements control such that seawater corresponding to the set seawater amount is supplied to the scrubber; and an alkalinity setting device (81) which sets the alkalinity of the seawater in accordance with traveled waters. The amount of seawater supplied to the scrubber is adjusted on the basis of the alkalinity.

摘要： Maintenance is performed on an ejecting section without temporarily removing an absorption tower from an installation platform. Therefore, since a crane or the like is not needed to remove the absorption tower, problems of space being needed to install the crane and cost increase due to installation of the crane are solved. In addition, the maintenance work time is shortened by the time needed to remove the absorption tower. Provided is an exhaust gas processing apparatus comprising an absorption tower that cleans exhaust gas by causing gas-liquid contact between the exhaust gas and a liquid. The absorption tower includes an ejecting section that ejects the liquid inside the absorption tower, and a door portion that is able to open and close at least a portion of a side wall of the absorption tower.
