摘要

针对现有红外传感器对各种挥发性有机化合物响应系数不同

导致难以对特定空间的挥发性有机化合物的气相浓度进行定量监测的难题

通过构建在线测试系统

用气相色谱仪测定结果对红外传感器测试数据进行校正

以获得挥发性有机化合物在传感器上的响应系数

用于校正传感器对特定有机物的定量监测值。分别利用气相色谱和红外传感器同时在线测试了核电安全壳检修期间主要的乙醇、异丙醇、正丁醇、甲苯、二甲苯和十一烷6种挥发性有机物的气相浓度

并使用气相色谱测定值与传感器测定值进行计算

获得了各挥发性有机物的红外传感器校正系数

所得校正系数在不同的浓度下对同一物质恒定。在应用中

将相应有机化合物的校正系数乘以红外传感器测试值即可得到该有机化合物在气相中的真实浓度值

同时根据各挥发性有机化合物的爆炸下限值

得出红外传感器监测的密闭空间内挥发性有机物安全浓度的监测范围。

Abstract

It is difficult to monitor the concentrations of volatile organic compounds(VOCs)quantitively since the response coefficients of VOCs on the infrared sensor are different due to their molecular structures. To solve this issue

an online testing system based on gas chromatography(GC)and infrared sensor is constructed to determine the concentrations of some specific volatile organic compounds in a container. In the online testing system

the correction coefficients of the infrared sensors towards the specific compounds used in the nuclear containment during maintenance

including ethanol

isopropanol

n-butyl alcohol

toluene

xylol and n-undecane

are calculated based on the data obtained on GC and infrared sensor

and the correction coefficients maintain stable in different concentrations. The correction coefficients can be used to correct the data obtained from the infrared sensors. Six main VOCs in the nuclear containment during maintenance are tested with this system

and the correction coefficients of the six VOCs are obtained based on the data from GC and infrared sensor. The concentration of relative chemical can be obtained through multiplying the infrared sensor datum by the correction coefficient. Furthermore

according to the lower explosive limits of VOCs

the VOCs monitoring method in confined space based on infrared sensor is then established.
