摘要:介绍了国内外船舶柴油机颗粒物排放标准以及IMO黑炭新规的进展,指出:船舶柴油机颗粒物排放控制将成为船舶柴油机行业的重点研究方向之一;黑炭测量方法的研究非常迫切。介绍了可同时降低柴油机NOx和颗粒物排放的SCRF技术(即将SCR催化剂涂覆在DPF上)。对高、中、低速船用柴油机排放颗粒粒径和数量浓度的分布特性进行了研究,并根据研究结果建议:在开发船用柴油机颗粒捕集器时,应根据颗粒粒径分布特性,适当调整过滤体微孔直径或增加再生频率。

Abstract:The PM emission standard of marine diesel engine both home and abroad, as well as IMO new regulations of black carbon are introduced. It is concluded that the PM emission control of marine diesel engines will become one of the key research tendency of marine diesel engine industry, and the research of black carbon measurement method become very urgent. SCRF technology, which coating DPF with SCR catalyst, and could reduce both NOx and PM of diesel engines are introduced. Moreover, the distribution characteristics of PM diameter and number concentration of high, medium, and low speed diesel engines are studied, and suggestions are given based on the analysis results that in the development of diesel particulate filter(DPF), based on the distribution characteristics of PM diameter, the diameter of filter medium micropore should be adjusted accordingly or regeneration frequency should be increased appropriately.
