摘要
针对超低排放烟尘在线实时监测问题,提出了基于图像传感器的在线实时测量烟尘质量浓度和粒度的新型光散射方法,并搭建实验装置对低质量浓度的烟尘颗粒进行测量。结果表明:低质量浓度下散射光强与烟尘质量浓度成正比;该方法能够满足超低排放烟尘浓度在线实时监测的要求,并能同时测量烟尘颗粒的平均粒径。
To realize the online measurement of ultra-low soot emission,a new method based on imaging light scattering was developed to measure the soot concentration and particle size,which was verified by experimental tests.Results show that under low soot concentration conditions,the intensity of scattered light is in direct proportion to the soot concentration.The method proposed can be used to measure not only the ultra-low soot concentration,but also the average particle size on a real time basis.
