摘　　要：介绍了NIR近红外光谱分析技术的特点及发展历史,提出了近红外光谱分析技术应用于出磨水泥生料质量检测控制时需关注的技术要点。近红外光谱分析仪安装于生料出磨斜槽处时,取样器宜为自动取样送样设备,取样点应尽量靠近NIR检测点,保持NIR检测位点为微负压状态,NIR分析仪工作时需进行降温处理,以确保NIR分析结果在误差允许范围内。对比分析了PGNAA中子活化分析技术和NIR分析技术的优缺点,结果表明,NIR分析技术的市场准入更便捷,综合成本优势更明显,后期维护更简易,具有广阔的应用前景。This paper introduces the characteristics and development history of near-infrared spectral analysis(NIR)technology.Technical points that need to be noted when applying NIR spectral analysis technology to the quality detection and control of cement raw meal out of the mill are proposed.When the near-infrared spectral analyzer is installed at the airslide where the raw meal exits the mill,the sampler better be an automatic sample-taking and sending type.The sampling point should be as close as possible to the NIR detection point,and the NIR detection site should be kept in a slightly negative pressure state.The NIR analyzer needs to be cooled during operation to ensure that the NIR analysis results are within the allowable error range.The advantages and disadvantages of PGNAA neutron activation analysis technology and NIR analysis technology are compared and analyzed.The results show that NIR analysis technology has more convenient market access,more obvious comprehensive cost advantages,and simpler later-stage maintenance,has certain application prospects.
