摘　　要：介绍了一种基于CCD光电特性的近红外比色成像系统,对乙烯裂解炉管表面进行温度测量,利用了图像测温的光电转换器件将拍摄的图像参数转换为温度数据,经过一次和二次补偿因子校准,使得系统的测量误差达到测量值的±0.6%或±6℃。实践证明,利用该技术测温稳定性好,精确度高,准确反映了炉管表面温度分布特性,跟踪炉管温度运行历史,对裂解炉产品收率的提高、裂解炉生产周期的延长,以及装置能耗、物耗的降低有一定的指导作用。A near infrared two-color imaging system is introduced to measure the surface temperature on ethylene pyrolyzer in this paper,In which the photoelectric converter（CCD）of image temperature measurement is used,and the image parameters are converted into temperature data.After the first and second compensation factor calibration,the system test error can reach ±0.6% of the measured value.The results show that the system is featured with steady measurement,small precision,and accurate display for the temperature distribution.Following the temperature dynamics can be highly beneficial to the yield of cracking furnace,the production cycle,the energy consumption and material consumption.
