摘要： 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) connected to discharge gas ducts (14); a storage unit (160, 160a) for storing prepared sludge powder; and a sludge powder feeder unit (190, 190a) for feeding sludge powder discharged from the sludge powder storage unit via a pneumatic conveying duct (200a, 200b) to a distributor (210a, 210b). The distributors (210) are connected to the final reduction reactor (30) and the preheating reactor (10), respectively, via sludge powder ducts (300 and 400) for blowing treated sludge powder. The invention reduces the amount of final sludge discharge and the treatment cost according to aftertreatment processes of sludge to enhance the productivity of the ironmaking system.
