Abstract

With the implementation of ultra-low emission policy in iron and steel industry, the original dust removal system of sintering machine tail can no longer meet the environmental protection requirements and emission standards, and it is in urgent need of transformation and upgrade. In this paper, the tail dust removal system of No.1 265 m2 sintering machine of Echeng iron and Steel Co., Ltd. was reformed by applying the key technologies of ultra-low emission transformation of sintering machine tail dust removal, such as annular cooling unloading smoke exhaust technology, tail closed top suction smoke exhaust technology, dust removal point optimization, dust removal pipe network system optimization design, purification facility optimization and integration. After the transformation, the working dust concentration and organized emission dust concentration are less than 0.5 mg•m-3 and 5 mg•m-3 respectively. The dust removal system has achieved double standards of dust emission concentration. At the same time, the annual particulate matter emission is reduced by 17 t, the annual material loss is reduced by 130 t, the system operation energy consumption is reduced by 43%, and the annual comprehensive operation cost is reduced by 3.45 million yuan, realizing good economic and environmental benefits.
