Ship exhaust gas treatment system with extended residence time in duct

摘要

Disclosed is a ship exhaust gas treatment device in which residence time in a duct is extended. The ship exhaust gas treatment apparatus in which the residence time in the duct is extended includes an exhaust gas inlet duct that provides a transport path of the exhaust gas; And a scrubber module that is connected to the exhaust gas inlet duct and processes harmful substances included in the introduced exhaust gas when exhaust gas flows in from the exhaust gas inlet duct along a transport path. The duct is provided at the rear end, provided in the vertical direction in the longitudinal direction, and when the exhaust gas being transported from the front end reaches, the transfer path of the reached exhaust gas is changed, so that the residence time of the exhaust gas is extended. It may include a member. Thereby, it is possible to remove harmful substances such as sulfur oxides contained in the exhaust gas using sea water or alkaline water, and to improve the treatment efficiency of the harmful substances contained in the exhaust gas.
