摘要
介绍了气体检测专用红外热像仪的工作原理,通过与传统方法比对,表明了热像仪在设备泄漏检测上的优势。分析了风速、距离对热像仪侦测结果的影响,风速越小效果越好,侦测距离宜在10m以内。用美国EPA关联方法,通过现场检测数据,计算了某公司委托检测装置年泄漏量(高达46.8t)。计算结果表明:热像仪发现泄漏设备所产生的泄漏量占装置设备无组织排放总量的99.4%。因此,把热像仪用于排查设备泄漏将会大大提高无组织排放源的确认效率,为石化装置开车过程、检修前以及正常运行过程的查漏和进一步治理无组织排放提供了有力技术支撑。
It was described the special Infrared gas detection works, compared with traditional methods, indicating that the thermal imager on the advantages of leak detection equipment. Also analyzed wind speed, from the results of the thermal imager to detect the impact, the smaller the better speed and detection distance should be at 10 m or less. It was associated with the U.S. EPA methods, through field testing data, calculated the company commissioned in leakage detection device （up to 46.8 t）. The results show that： thermal imaging equipment found to leak the leak generated by installing equipment fugitive emissions accounted for 99.4% of the total. Therefore, the thermal imager for troubleshooting equipment leak fugitive emissions will greatly improve the efficiency of the source of confirmation for the petrochemical plant to drive the process, maintenance before and during normal operation of the leak and to hirther control fugitive emissions provided strong technical support.
