摘　　要：为研究不同来源颗粒物的再生性能,收集了不同类型的船用发动机燃用不同品种燃油的排气颗粒物,通过外加热源再生试验台进行再生试验,测试了再生过程载体内温度、压降、气体排放、颗粒物排放及再生效率。试验结果表明,在相同再生条件下,相较于燃用柴油的船用高速发动机排气颗粒物与市售碳黑(PU),燃用重油的船用中、低速发动机的排气颗粒物再生时存在快速再生期,会形成明显温度波峰,且再生效率可达80%以上;但在再生过程中形成温度峰值时间段内,重油颗粒再生所产生的气体与颗粒物的排放浓度相对较高,会产生较高浓度CO_(2)排放及粒径在0~30 nm的核膜态颗粒。研究结果可为船舶发动机燃用不同种类燃油时的颗粒物捕集器再生条件及排放控制提供参考。In order to study the regeneration performance of particulate matter from different sources,the exhaust particles from different types of marine engines burning different types of fuels were collected.The regeneration test was carried out through an external heat source regeneration test bed.The temperature,pressure drop,gas emission,particle emission and regeneration efficiency in the regeneration process were tested.The test results show that:under the same regeneration conditions,compared with the exhaust particles from marine high-speed engines burning diesel and commercial Printex-U,the exhaust particles from marine medium-speed and low-speed engines burning heavy oil have a rapid regeneration period during the regeneration process,which will form an obvious temperature peak,and the regeneration efficiency can reach more than 80%.However,during the period of temperature peak formation in the regeneration process,the emission concentration of gas and particles generated by the regeneration of heavy oil particles is relatively high,and a high concentration of CO_(2)emission and nuclear film particles with a particle size of 0~30 nm will be produced.The research results can provide reference for the regeneration conditions and emission control of particulate matter catchers when marine engines burn different types of fuels.
