Title:
EXHAUST EMISSION CONTROL DEVICE FOR VESSEL
Document Type and Number:
Japanese Patent JP2017075579
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an exhaust emission control device capable of suppressing efficiency deterioration of reduction action (denitration action).SOLUTION: An exhaust emission control device for a vessel 1 according to this invention includes a reducing agent injection body 61 of a reducing agent supply device for supplying a reducing agent to exhaust gas passing through an exhaust pipe of an engine 21 for mounting on the vessel, an exhaust mixer 62 for mixing the exhaust gas and the reducing agent in an exhaust gas movement direction downstream side of the reducing agent injection body 61, and selective catalytic reduction devices 34 and 35 for prompting reduction of NOx in the exhaust gas of the engine 21 in the exhaust gas movement direction downstream side of the exhaust mixer 62. A plurality of the reducing agent injection bodies 61 are provided, and injection ports of the reducing agent injection bodies 61 are arranged in equal intervals along a circumferential direction of the exhaust pipe.SELECTED DRAWING: Figure 9
