| 针对超低排放的烟气监测，研制了基于紫外差分吸收光谱技术的便携式高温烟气分析仪，阐述了分析仪的测量原理以及仪器的机械结构、光学、温控设计，采用不同浓度的SO2和NOX标准气体在不同环境条件下对该仪器进行测试，结果表明仪器的性能指标可达到污染源环保管理和环境污染应急监测的要求，具有良好的环境适应性。基于该仪器的硬件平台，未来通过扩展设计和应用开发升级也可应用于大气监测领域的走航监测。 |
| 英文摘要: |
| For ultra-low emission flue gas monitoring, a portable high temperature flue gas analyzer based on UV differential absorption spectrum technology is developed and designed. The measurement principle, mechanical structure, optical and temperature control design of the analyzer are described in this article. The instrument is tested under different environmental conditions with different concentrations of SO2 and NOx standard gas. The test results show that the performance index of the instrument can meet the requirements of environmental protection management and environmental pollution emergency monitoring, and it has good environmental adaptability. In the future, based on the current hardware platform of the instrument, it can also be applied to the navigation monitoring in the field of atmospheric monitoring through the extended design and application development. |
