Diesel Particulate Filter for Exhaust Gas from Marine Diesel Engines and Optimization of Its Regeneration System

Abstract

The aftertreatment of the exhaust gas from marine diesel engines plays an important role in the protection of atmospheric and marine environment. For the soot particulate matter (PM) emitted from marine diesel engines, a mathematical model was established to optimize the cellular structure of the filter. Using the asymmetric cell technology (ACT) combined with a rotary microwave continuous regeneration structure, a novel device was designed to capture and filter the PM exhaust gas from marine diesel engines. It not only had the high ash volume and low exhaust gas resistance of ACT structure, but also featured the low energy consumption and continuous regeneration of rotary filter.
