Abstract

Przedmiotem zgłoszenia jest sposób odzysku metali z odpadów pohutniczych, zwłaszcza cynku i żelaza z pyłów, który to sposób charakteryzuje się tym, że cynkonośne pyły poddawane są granulowaniu z dodatkiem reduktora (pył węglowy, karbonizat, koksik), w ilości w granicach 7% — 25% masy wsadu metalonośnego i tak przygotowany materiał kierowany jest do pieca elektrycznego łukowo-oporowego, w którym topi się go w temperaturze 1350°C - 1600°C, gdzie równocześnie zachodzą procesy redukcji tlenków cynku i żelaza, po czym cynk w postaci gazowej jest odpędzany i utleniany w strumieniu powietrza, po czym następuje dwuetapowe odpylanie fazy gazowej, gdzie w komorze wstępnego odpylania odbierane są grubsze frakcje pyłów i zawracane do procesu, a w dalszej części układu odpylania następuje schłodzenie gazów poniżej 200°C i skierowanie ich na filtry workowe celem wychwytu i odzysku tlenku cynku w formie drobnego pyłu, natomiast stop żelaza i żużel odpadowy są z niego spuszczane, po czym stop żelaza kierowany jest do pieca indukcyjnego lub łukowego, w którym następuje jego modyfikacja jego składu chemicznego poprzez usunięcie nadmiaru węgla, siarki i fosforu i dodanie złomu stalowego lub dodatków stopowych do stopów handlowych.
