【摘要】 介绍了一种烟囱颗粒物排放的实时监测装置。该装置基于光散射理论 ,使用一个半导体激光器件作为光源 ,用 4个光电元件分别测定入射光强、从测量区出射的光强及前向两个立体角的散射光能 ,使用一台微机对接收信号进行处理 ,能够实时地给出烟囱排放源的排放浓度及粒径分布。更多还原

【Abstract】 A real\|time monitoring device of particulate emissions in stack,which is based on light scattering theory is presented.A semiconductor laser is used as light source in the device and four photodetectors are used to measure the incident light intensity,emerging light intensity and the light scattering energy of two forward solid angle respectively.All collected signals are sent to a microcomputer for data processing.This device can be used for performing continuous and on\|line measurment of mass concentration and particle size distribution of emissions from a stack.更多还原
