"Byproduct Sludge Recycling Apparatus In Ironmaking System"
Abstract: In an ironmaking system using non-coking coal and fine iron or directly in furnace operations without any additional treatment, a byproduct sludge recycling apparatus powders wet byproduct sludge which is by-produced in water treatment of discharge gas and then re-blows sludge powder into fluidized-bed reduction reactors so that byproduct sludge can be recycled. In the ironmaking system including the fluidized-bed reduction reactor (10, 20 and 30) and an HBI making apparatus (50), the byproduct sludge recycling apparatus (1) comprises: a sludge powder preparing unit (120) for preparing sludge powder by dewatering, drying and crushing byproduct sludge discharged from a water treatment unit (70) for treating process water from scrubbers (60) ...
