摘要
针对固定污染源排放挥发性有机物的特点,研制了一套基于色谱技术的固定污染源挥发性有机物在线监测系统,该系统采用全程高温预处理技术和高温色谱技术。本文详细描述了该系统主要组成结构、技术特点、性能参数和现场应用测试。测试结果表明,所研制的固定污染源挥发性有机物在线监测系统具有测量精度高、线性范围宽、现场适性强等特点,满足固定污染源排放烟气中挥发性有机物的在线监测要求。
An on-line monitoring system for volatile organic compounds(VOCs) was developedbased on chromatographic technique. The system uses the pretreatment technology of high-temperature dehumidification and the instrumentation of high-temperature sample loop for the fixed-source VOCs. The main structure, function characteristics, performance test and field application test of the system are described in detail. The test data and field application results showed that the on- line monitoring system of volatile organic compounds has high precision, wide linear range and strong universality, so it can meet the requirements of on- line monitoring of volatile organic compounds in stationary sources.
