摘要

With the improvement of the international community s environmental requirements, ship emissions standards are more stringent. In order to complete the exhaust gas purification work, Dafa 6DL-26 diesel engine set is used for simulation. Finite element multi-phase flow model and DPM model are used for numerical simulation and structural optimization of the position of dust removal tank at the desulfurization pretreatment part (Venturi segment). The results show that it can effectively optimize the flow field and reduce the power consumption of the marine diesel engine when the rightmost axis of the dust removal tank coincides with the axis of the Venturi center.
