| 摘 要： | 本文介绍了一种对电厂排放SO2气体浓度进行评估的简单的数据处理方法,这种方法是基于紫外宽带吸收光谱技术,利用SO2气体在300 nm处具有强吸收的特性,从而最终得到SO2的浓度。这种数据处理方法的优点是可以大大减少其它气体成分和粉尘对测量的干扰,稳定性好,响应时间短,尤其是具有很低的探测限。在文中我们讨论了仪器的设计方法,测量原理和实验过程,并且对电厂排放SO2进行了测量研究。

| Abstract: | In this paper we have developed a simple,data-processing approach for detecting concentration of sulfur dioxide(SO2) emissions from coal based power plant,the method is based on SO2 inherent choice absorption property in the ultraviolet spectral range of 300nm.This data processing approach has the advantages of limited interference from other gases and dust,high stability,short response time and low detection limits.The instrument design,measuring principle,experimental process and results are described. |
