油气站场可燃气体探测器标准体系的对比分析

Research on Standard System of Combustible Gas Detector in Oil and Gas Station

针对国内油气站场可燃气体探测器的设置场所、安装与维护等标准不一致的问题,介绍了美国、加拿大、俄罗斯等国外管道行业在可燃气体探测器的产品选型、设置场所、报警设定值、运行维护和培训方面的先进经验,包括连续性监测重要场所探测器的传感器采用冗余设计,一级报警设定值<20%LEL,复杂场所和恶劣气候条件下探测器的防护措施以及故障时的替代措施等。提出了完善国内可燃气体探测器标准的建设,对提高我国管道行业安全管理水平具有参考意义。

In view of the disagreement of the standards on location,installation and maintenance of flammable gas detector in domestic oil and gas stations,the advanced experience of the products selection,location,alarm setting value,operation maintenance and training of flammable gas detectors in the United States,Canada and Russia are introduced,including the redundancy design used for the sensor of combustible gas detector in the important place of continuous monitoring,the set value for the first order alarm lower than 20%of LEL,the protection measures of the detector in complex places and bad climate conditions,and the replacement measures in the time of failure.Suggestions for improving the standards of domestic combustible gas detectors are put forward.
