摘要：
Provided is an exhaust gas treatment equipment for a marine diesel engine with high PM collection efficiency capable of effectively collecting PM contained in exhaust gas of the marine diesel engine using fuel oil. The exhaust gas treatment equipment includes: an electric precipitation means having a tubular collecting unit composed of a discharge electrode for charging particulate matter contained in the exhaust gas and a precipitation electrode for collecting the particulate matter charged, the discharge electrode being disposed in the tubular collecting unit; a precipitation means for collecting the particulate matter detached from the tubular collecting unit; and a low-concentration exhaust gas delivery pipe and a high-concentration exhaust gas delivery portion for the particulate matter provided on a downstream side of the tubular collecting unit, the precipitation means being connected to the high-concentration exhaust gas delivery portion, wherein one or more of tubular collecting modules being arranged in combination in the tubular collecting unit formed of the discharge electrode and the precipitation electrode, the tubular collecting modules having a short dimension in an axial direction and having different diameters.
