摘要
光谱测量方法作为新型SO_3检测方法,呈现出了高灵敏度、稳定、可靠、准确等优点。光程池作为系统的重要部件,影响着整个系统检测性能。论文依据SO_3的化学特性,采用Herriott池结构原理,设计出了针对于SO_3中红外气体检测系统的光程池结构,通过光路追迹,分析光束传输次数,最后确定了在0.25m长的基础上实现了11.5m的光程,且具有耐腐蚀、光路简单稳定、易调节的特点,适用于光谱测量法的应用。
pectroscopic method presents the advantages of high sensitivity,stability,reliability and accuracy as a new typeof SO_3 detection method. Multipass optical absorption cell,the important part of the system,affects the detection performance of thesystem. According to the chemical properties of SO_3 and the Herriott type,a multipass optical absorption cell is designed for themid-infrared region in SO_3. It finally achieves 11.5 meters long optical path based on the length of 0.25 m through the light path trac-ing and analysis of the beam transmission times. It also considers the corrosion resistance,simple and stable light path and easy tobe adjusted. It is proved to be suitable for the application of Spectroscopic method.
