【摘要】：在柴油机上分别燃烧纯地沟油生物柴油和纯石化柴油在每一负荷工况下运用颗粒物测试系统NanoMet3研究碳烟微粒的排放及肺沉积表面积。结果表明:各工况下,地沟油生物柴油碳烟微粒数量浓度及质量浓度均小于石化柴油。小负荷时两种燃料的差距不大;大负荷时,地沟油生物柴油碳烟微粒数量浓度及质量浓度远小于石化柴油;但增幅高于石化柴油。地沟油生物柴油碳烟微粒的平均粒径比石化柴油小,其肺沉积表面积小于石化柴油,对人体的危害值低于石化柴油。碳烟微粒肺沉积表面积受到平均粒径和数量浓度的共同作用,其增幅与数量浓度的增幅呈现出相同的变化趋势。
[Abstract]:Combustion of pure gutter oil biodiesel and pure petrochemical diesel oil on diesel engine under each load condition was studied by particulate matter test system (NanoMet3). The results show that: (1) the emission of soot particles and the surface area of lung deposition are studied. Under all working conditions. The amount and mass concentration of soot particles in gutter oil biodiesel are lower than those in petrochemical diesel oil. At high load, the quantity and mass concentration of soot particles in gutter oil biodiesel is much lower than that in petrochemical diesel oil. But the increase was higher than that of petrochemical diesel oil. The average particle size of soot particles of waste oil biodiesel was smaller than that of petrochemical diesel oil, and its lung deposition surface area was smaller than that of petrochemical diesel oil. The damage value to human body is lower than that of petrochemical diesel oil, and the pulmonary deposition surface area of soot particles is affected by the average particle size and the concentration of quantity, and the increase of the increase is the same as the increase of the quantity concentration.
