摘要
文章主要研究了黑色金属冶炼及压延加工业PM2．5的排放特征，采用ELPI（Electrical Low Pressure Impactor）静电低压撞击器对烟气中的颗粒的粒数分布及质量浓度分布进行在线分析，通过自动烟尘测试仪采集样品，并对颗粒物的形貌、聚集特性、化学组分及物相组成等进行了深入研究，为中国工业排放PM2．5颗粒的来源分析及PM2．5对健康、气候的影响提供了有力的数据依据。
Research the emissions characteristics of PM2.5 in ferrous metal smelting and rolling processing industry, Taking ELPI to analysis the grains distribution and mass concentration of particles in the title gas on line. Got samples through automatic smoke tester. And took in-depth research on the morphology of the particles, gathered characteristic, chemical composition and phase composition. Provided strong basis for the impact of PM2.5 on health and analysed climate ,and analysis the emission sources of PM2.5 particle in Chinese industrial.
