摘要
可燃气体探测报警系统是保证油气管道站场设备和人员安全的重要设施。国内已有可燃气体探测报警系统的设计、产品参数、施工安装调试以及检定校准等标准,但整体还不完善。以新发布的美国标准ISA-60079-29-2(12.13.02)-2012《爆炸性气体环境第29-2部分:气体探测器——易燃气体和氧气探测器的选型、安装、使用和维护》为例,介绍了美国油气管道站场可燃气体探测报警系统在产品选型、传感器冗余设计、设置场所、报警设定值、运行维护和使用方法培训方面的先进经验和推荐做法,例如远程控制可燃气体探测报警系统的传感器采用双重或三重冗余设计,可燃气体探测报警系统一级报警设定值<20 LEL,以及故障时应采取的替代措施等。最后,提出了借鉴美国标准完善国内可燃气体探测报警系统标准的建议。
Combustible gas detecting alarm system was an important facility for the safety of personnel and equipment in oil and gas station.In allusion to gas detection alarm system design,product parameters,construction and installation,testing and calibration,the domestic standards were relatively imperfect.Taking the newly-issued American standard ISA-60079-29-2(12.13.02)-2012 Explosive Gas Atmosphere-Part 29-2:Gas Detector-Selection,Installation,Using and Maintenance of Inflammable Gas and Oxygen Detector as an example,the paper introduced the advanced experience and recommended practice of American combustible gas detector from product selection,sensor redundancy design,setting position,alarm setting value,operation and maintenance and training.The advancement of ISA-60079-29-2-2012 included double or triplex redundancy design of remote control combustible gas detector,less than 20%LEL for first alarm setting value of combustible gas detector,alternative measures under combustible gas detector failure.Finally,the suggestion of adopting American standards to improve domestic combustible gas detection and alarm system standards was made.
