烧结机增设烟气循环与漏风治理实现提产降耗
Adding Flue Gas Circulation and Air Leakage Treatment to Sinter Machine to Increase Production and Reduce Consumption

烧结工序是钢铁联合企业的污染及耗能大户，烧结风量分为有效风量和有害漏风，烧结机的有害风量的多少直接影响了烧结矿的质量。目前，部分烧结机作业时，有害风量即烧结机实际漏风率高达60%，配套脱硫脱硝系统运行负荷升高，大幅增加了生产成本，严重制约了钢铁企业的绿色发展。因此，充分利用烧结烟气的显热和潜热，减少废气排放量，降低环境污染，同时加强漏风烧结机系统漏风的治理已成为亟待解决的问题，本文着重讲述烧结机通过增设烟气循环及漏风治理实现提产降耗。
Sinter process is a big polluter and energy-consuming enterprise in iron and steel industry. Sinter air quantity can be divided into effective air quantity and harmful air leakage. The amount of harmful air volume of sintering machine directly affects the quality of sinter. At present, the actual air leakage rate of sintering machines is as high as 60% when some sintering machines are working, and the load of the desulphurization and denitrification system increases, which greatly increases the production cost and restricts the green development of iron and steel enterprises. Therefore, it is an urgent problem to make full use of sensible heat and latent heat of sintering flue gas, reduce exhaust gas emissions, reduce environmental pollution, and strengthen the treatment of air leakage in the sintering machine system. This paper focuses on the sintering machine through the addition of flue gas circulation and air leakage treatment to achieve production and consumption reduction.
