Summary of air leakage control technology and evaluation for iron ore sintering system
In the sintering process of iron ore with"wind as the key link",air leakage has a serious adverse effect on sintering production,such as increasing the power consumption of main exhaust fan,reducing the quality and output of sintering production,accelerating equipment failure,and increasing the difficulty of environmental protection.Based on the analysis of air leakage positions for sintering machine,the detection method of air leakage rate for sin-tering machine is introduced.It is pointed out that the air leakage rate of sintering system should be comprehensively evaluated by combining static flow method with flue gas composition analysis method.The key technologies of air leakage control of sintering machine are comprehensively sorted out and analyzed,and the comprehensive sealing technology of sintering machine represented by negative pressure adsorption end sealing technology is emphatically analyzed.The effective measures and effects taken by iron and steel enterprises at home and abroad for air leakage of sintering machine are summarized,which provide reference for air leakage control of sintering machine.
