摘要

摘要: 分析DOAS原理和DOAS系统设计表明，DOAS系统可以监测从紫外(UV)波段到红外(IR)波段的多种气体浓度。经TüV认证机构测试，DOAS系统性能符合监测标准，适用于普通固定污染源和垃圾焚烧厂烟气排放连续监测，尤其在监测Hg，HCl，NH₃和HF等气体时有明显优势。采用多通道技术可以只使用一台主机同时监测多个测点。DOAS系统可以在高温、腐蚀性强和含尘量高的环境中正常工作，使过程工艺气体在线监测得以实现。DOAS系统还可以监测不同位置不同浓度的气体。无需采样、反应速度快、多组分多通道的特点为DOAS系统有更广阔的应用奠定了基础。

Abstract: The principle and system design of DOAS indicated the system could monitor multi-gas from UV wavelength to IR wavelength. After a series of test and identification from TüV, the DOAS system had proven to have a good performance on continuous emission monitoring in stationary pollution source and waste incineration, especially to monitor Hg, HCl, NH₃ and HF. The DOAS system could monitor different concentrations of process gas with several paths using one analyzer and work well where was corrosive, high temperature and high level dust,which made it possible to monitor progress gases. The system also could monitor different concentrations of gases in different places. No extract sample system, faster response speed, multi-component and multi-path monitoring by one analyzer laid foundation for the DOAS a good competition on the market.
