烟气净化碳基材料产品质量及检测团体标准解读

Interpretation of group standards on quality and testing standards of carbon-based materials for flue gas purification

活性炭法烟气多污染物协同高效净化技术已广泛应用于钢铁烧结和球团烟气处理,其核心碳基材料直接决定了该技术应用的安全性、稳定性及经济性。然而,当前执行的碳基材料产品质量标准及检测标准存在针对性不强、检测方法待完善、检测设备待提升等问题,为规范统一烟气净化碳基材料性能检测及质量分级,亟需制定一套能同时实现技术先进、科学准确、方便快捷的检测标准及质量标准。为此,在中国冶金建设协会的指导下,由国内某设计院会同有关单位共同编制完成了《烟气净化碳基材料产品质量标准》和《烟气净化碳基材料产品检测标准》,编号分别为T/CMCA 40027—2022和T/CMCA 40028—2022。2项标准均自2023年2月1日起实施,标准实施1年来,市场反馈良好,对指导碳基材料企业产品生产、钢铁企业产品应用起到了积极地促进作用。为了进一步推动上述2项标准更快更好地应用于生产实际,从标准编制背景、活性炭法烟气多污染物协同高效净化技术分类、主要标准内容、指标设置、方法创新、设备创新等角度展开详细的解读。指标设置方面,新增了湿容量指标,重新规定了SO_(2)(循环)吸附值及循环脱硫脱硝性能概念及测试方法,标准服务工程针对性更突出;方法创新方面,重新规定了耐磨强度、耐压强度、堆积密度测试方法,测试结果更接近真实值;设备创新方面,开发了粒度分布、着火点、挥发分测试设备,测试效率大大提高,测试结果更加准确。

The activated carbon for flue gas multi-pollutant synergistic high-efficiency purification technology has been extensively implemented for the treatment of flue gases from steel sintering and pelletization processes,with carbon-based materials as the core playing a crucial role in ensuring the safety,stability,and cost-effectiveness of the technology.However,the current enforced product quality standards and testing standards for carbon-based materials lack specificity,have incomplete testing methods,and require improvements in testing equipment.To standardize and unify the performance testing and quality grading of flue gas purification carbon-based materials,it is imperative to establish a set of advanced,scientifically accurate,and convenient testing and quality standards.In this context,under the guidance of the China Metallurgical Construction Association,A domestic design institute together with other relevant organizations,has jointly compiled the"standard specification of carbon-based materials for flue gas purification"and the"performance test standard of carbon-based materials for flue gas purification,"numbered as T/CMCA 40027—2022 and T/CMCA 40028—2022,respectively.Both standards have been in effect since February 1,2023.Over the past year,the implementation of these standards has received positive market feedback,significantly promoting the production of carbon-based materials and their application in steel enterprises.To further expedite the application of these standards in practical production,a detailed interpretation from various perspectives was provided,including the background of standard compilation,classification of the synergistic and efficient purification technology using activated carbon,main standard contents,index settings,method innovations,and equipment innovations.In terms of index settings,a new wet capacity index has been added,and the concepts and testing methods for SO_(2)(cyclic)adsorption value and cyclic desulfurization and denitrification performance have been redefined,making the standard more targeted for engineering services.Regarding method innovations,the testing methods for wear resistance,compressive strength,and bulk density have been redefined,resulting in test results that are closer to actual values.In terms of equipment innovations,devices for testing particle size distribution,ignition point,and volatile matter have been developed,significantly improving testing efficiency and accuracy.
