摘要
密闭空间是一个独特大气环境,人员在其中长期工作生活存在着缺氧、二氧化碳和有害气体超标的风险,密闭空间环境监测对作业人员的生命安全和身体健康起着至关重要的作用.旨在针对密闭空间的特点,分析了密闭空间空气污染物来源及危害,对密闭空间光谱监测技术、色谱-质谱联用监测技术、色谱-离子迁移谱监测技术、半导体监测技术、电化学监测技术、光离子化监测技术的特点、应用及发展趋势进行了分析,为不同类型的环境监测技术在密闭空间中的应用提供借鉴和参考.
Abstract
Confined space is a unique atmospheric environment,and there are the risks of hypoxia,carbon dioxide and harmful gases exceeding the standard when personnel work and live for a long time in it,so environmental monitoring in confined space plays a vital role in the life safety and health of operators.Based on the characteristics of confined space,this paper analyzes the sources and hazards of air pollutants in confined space,and analyzes the characteristics,applications and development trends of spectral monitoring technology,chromatography-mass spec-trometry monitoring technology,chromatography-ion mobility spectrometry monitoring technology,semiconduc-tor monitoring technology,electrochemical monitoring technology and photoionization monitoring technology in confined space,so as to provide models and reference for the application of different types of environmental moni-toring technology in confined space.
