摘要
工业烟道是大气中悬浮颗粒物的主要排放源,这些悬浮颗粒物对人体健康产生直接的负面影响,受到各国政府及有关研究部门的高度重视。在线监测工业烟道固体颗粒的质量排放量对遏制污染源,保护大气环境具有重要作用。固体颗粒质量排放量与固体颗粒排放浓度、速度密切相关。针对我国目前新的环境保护政策,阐述了几种基于静电测量原理的大气中粉尘主要排放源———工业烟道中固体颗粒物质量排放量的在线自动连续监测方法。给出了这些方法的原理,系统构成及它们的使用特点。
Industrial stocks are main source from which the suspended powdery solids in the air are being emitted.Those solids directly have negative effect to the health of human beings,so all the governments in different countries are taking strict policy to protect the pollution caused by the solids coming from industrial stocks.On-line monitoring the mass emission of powdery solids from the stocks plays an important role in environment protection.Presents some of methods,based upon electrostatics,for on-line monitoring the mass emission of powdery solids from the industrial stocks.Principle of the measurements,construction and features of the monitoring systems are described.
