摘要:
对应用蒸汽相变原理作为脱除燃烧源PM2.5预调节措施的效果进行了试验研究.结果表明,蒸汽相变与常规除尘技术结合可有效脱除PM2.5,对燃煤、燃油PM2.5的脱除效率可分别提高80%,60%以上; 相变核化室壁面性能,颗粒物化性质及蒸汽过饱和度对PM2.5凝并长大效果均有重要影响,采用低表面能的核化室壁面材料可明显改善蒸汽相变预调节的效果; 强疏水性的燃油PM2.5颗粒凝并长大效果明显不及燃煤PM2.5颗粒,适当提高蒸汽添加量有助于增进相变效果.
Abstract:
Based on enlargement of fine particles by heterogeneous condensation of water vapor, removal of PM2.5 from combustion was investigated experimentally. The results show that vapor heterogeneous condensation combined with normal inertial dust separator can effectively remove PM2.5of which the removal efficiency can reach more than 80% and 60% from coal and oil combustion respectively. Surface properties of the condenser, physical-chemical characteristic of fine particles and the super saturation have important effect on PM2.5 growth and removal. The condenser with low surface energy can obviously improve the growth and removal of PM2.5. The removal efficiency of strong hydrophobic PM2.5 from oil combustion is much lower than PM2.5from coal combustion. Increasing the condensable mass of water vapor properly can also improve PM2.5 growth and removal.
