摘要

烟气中SO2气体体积分数的检测一直是人们关心的热点问题

在深入分析SO2的荧光检测机理的基础上

提出了一种新型的时间双光路SO2荧光检测方法

通过对2个滤光片交替工作得出的荧光信号进行加权处理

解决了单光路测量中存在交叉敏感和背景噪声的问题。

Abstract

The research on the detection of sulfur dioxide volume fraction in flue-gas is a hot topic all the time.Based on the analysis of the measuring principles for the sulfur dioxide volume fraction using ultraviolet fluorescence method

a new measuring method using time-divided double optical paths is proposed.This method overcomes the problems of cross sensitivity and background noise in single path measurement because it takes advantage of the fluorescence signals produced by the alternation of two light filters.
