摘要

摘要: 量子电炉是一种能够实现高效废钢预热的炼钢电弧炉，近年来在我国得到了规模化应用。然而，关于量子电炉二噁英排放及控制的研究尚处于空白，亟待系统化探索与实证补充。为研究量子电炉二噁英的排放情况，选取华东地区某100 t全废钢冶炼量子电炉为试验对象，结合电炉实际冶炼工艺，对不同工序周期下烟气中的二噁英浓度、三相分布以及种类进行测试分析，明确了量子电炉二噁英排放特征与时空规律，确定了二噁英生成的关键期。结合量子电炉的废钢预热特点以及试验电炉烟气处理系统等实际运行情况，分析了二噁英的产生以及超标原因，并尝试通过高效活性炭喷射法来降低二噁英排放浓度。最后，基于分析结果，结合当前我国电炉炼钢的行业特点，提出了具有针对性的电炉二噁英排放应对策略。

Abstract: Quantum electric furnaces are a type of steelmaking electric arc furnace capable of achieving efficient preheating of scrap steel，and have been widely applied in China in recent years. However， research on dioxin emissions and control from quantum electric furnaces is still in its infancy， and urgently requires systematic exploration and empirical supplementation. To study the emissions of dioxins from quantum electric furnaces， a 100-ton quantum electric furnace for smelting all scrap steel in East China was selected for test. Combined with the actual smelting process of the electric furnace， the concentration， three-phase distribution， and types of dioxins in the flue gas under different process cycles were tested and analyzed. The emission characteristics and spatio-temporal laws of dioxins from quantum electric furnaces were clarified， and the critical period for the generation of dioxins was determined. Combined with the preheating characteristics of scrap steel in the quantum electric furnace and the actual operation of the flue gas treatment system of the test electric furnace， the generation of dioxins and the reasons for exceeding the standard were analyzed， and an attempt was made to reduce the emission concentration of dioxins through the efficient activated carbon injection method. Finally， based on the analysis results and the current industry characteristics of electric furnace steelmaking in China， targeted strategies for dealing with dioxin emissions from electric furnaces were proposed.
