利用熔炉废气还原氧化铁球团的方法

一种利用熔炉废气还原氧化铁球团的方法，具有旁路管道(3)，其将具有还原气体的熔炉(2)废气直接引导至反应器(5)中，并且使用初级除尘系统的负压力(7)将气流引导回除尘系统的主管道。废气直接加热氧化铁球团并且保持反应器中的还原气体，以及使反应继续进行并且防止再氧化。 The invention relates to the use of off-gas from furnaces (2) for the process of reduction of iron oxide. The bypass duct leads off-gas with reduction atmosphere directly into the reactor, passing through and back to join the main duct of dedusting system using negative pressure of the primary dedusting system. The off-gas directly heats up the iron oxide pellet and maintain the reduction atmosphere in the reactor and allow the reaction to proceed and prevent re-oxidation.
