Abstract

본 발명은 제철분진의 처리방법으로 선철을 제조하는 고로조업 등의 제철공정중 배출되는 배가스를 정화하기 위하여 물을 살수하여 포집되는 분진 중에서 유해성분을 제거하여 제철자원으로 활용하기 위한 제철분진의 처리방법에 관한 것이다.The present invention removes harmful components from the dust collected by sprinkling water in order to purify the exhaust gas discharged during the steelmaking process such as blast furnace manufacturing to manufacture pig iron as a method of processing iron and dust to use as steelmaking resources. It is about a method.

본 발명의 제철 분진의 처리방법은 제철공정중 고로에서 발생하는 분진을 슬러리화하여 습식 사이클론에서 탈아연처리하는 습식분급 공정에 있어서, 습식 사이클론의 슬러리 투입구 단면적을 48-144㎟, 사이클론 내부의 하향류가 배출되는 에이팩스 밸브의 직경을 8-14㎜, 내부의 상향류가 배출되는 보텍스 파인더의 직경을 15-25㎜로 하고, 슬러리의 사이클론으로의 공급 압력을 1.0-2.0㎏/㎠으로 한다.In the method for treating iron dust of the present invention, in the wet classification process in which the dust generated in the blast furnace during the steelmaking process is slurried and de-zinc treated in the wet cyclone, the slurry inlet cross-sectional area of the wet cyclone is 48-144 mm2 and downward in the cyclone. The diameter of the apex valve through which the flow is discharged is 8-14 mm, the diameter of the vortex finder through which the internal upstream is discharged is 15-25 mm, and the supply pressure to the cyclone of the slurry is 1.0-2.0 kg / cm 2. .
