摘要: 目前,平板式烟气脱硝催化剂的活性检测模式主要参考国内外相关标准中所规定的方法执行,而在实际应用中往往存在适用范围窄、检测精度差等弊端。为提高平板式烟气脱硝催化剂活性检测的准确性,以及便于开展不同批次、不同厂家产品之间的比对,对现行检测方法展开论述,分析其特点和所存在的问题,提出了优化改进措施,同时通过试验对改进后的方法进行了验证。研究结果表明,所提出的改进方法解决了不同类型平板式催化剂之间脱硝活性的检测比对问题,并有效改善了传统检测模式下存在检测单元结构不稳定的缺陷,使得检测精度、准确度和可重现性得到显著提升。

Abstract: At present, although activity detection of the plate-type De-NOx catalyst is carried out primarily with reference to methods specified in the domestic and international standards, there have been some issues in existence in practice, such as limited scope of applications and poor detection precision. In this article, the features and existing problems in traditional detection modes are analyzed, then the improvements and optimization procedures are provided to not only enhance the accuracy of activity detection but also make comparison among plate-type De-NOx catalysts from various production batches and manufacturers. The efforts to improve detection methods are demonstrated through a series of practice tests. The study outcome indicated that, improved detection methods solved the De-NOx activities comparability problem between plate-type De-NOx catalysts of different types. Also the defect of structural instability in detecting unit with traditional methods is effectively improved, which resulted in significant promotion in the aspects of the detection precision, accuracy and repeatability.

Key words: SCR De-NOx, plate catalyst, activity, denitrification efficiency, detection method
