摘　　要：典型转炉炉前排烟罩由于捕集效率低,烟气外逸严重,造成炼钢车间主厂房环境质量降低,不仅影响转炉的正常生产,也损害了工人的身心健康,因此提高转炉炉前排烟罩捕集效率成为了转炉炼钢企业的研究重点。采用数值模拟的研究方法,重点分析了运输通道进风阻力对转炉炉前排烟罩捕集效率的影响,通过分析发现,增加运输通道两侧进风阻力可以提高炉前排烟罩的捕集效率,并且当运输通道环境侧进风阻力明显小于厂房侧进风阻力时,炉前排烟罩可以获得更高的捕集效率。根据分析,提出了一种可提高转炉炉前排烟罩捕集效率的优化方法。.Due to the low capture efficiency and serious flue gas escaping from the front row hood of a typical converter furnace,the environmental quality of the main workshop of the steel-making workshop is reduced,which not only affects the normal production of the converter,but also damages the physical and mental health of the workers.Therefore,improving the collection efficiency of the front row hood of the converter furnace has become the research focus of the converter steel-making enterprises.The numerical simulation method is used to analyze the influence of the air inlet resistance of the transport channel on the collection efficiency of the front row hood of the converter furnace.Through the analysis,it is found that increasing the air inlet resistance on both sides of the transport channel can improve the collection efficiency of the front row hood of the converter,and when the air inlet resistance at the environmental side of the transport channel is obviously less than the air inlet resistance at the plant side,the front row hood of the converter can obtain higher efficiency Capture efficiency.Based on the analysis,an optimization method is proposed to improve the efficiency of front row hood of converter.
