| titleOfInvention | A kind of zinc leaching residue processing dual chamber Double bottom side-blown converter and its processing method |
| abstract | The invention discloses a kind of zinc leaching residue processing dual chamber Double bottom side-blown converter and its processing methods, natural gas and oxygen-enriched air are passed through into side-blown converter by gas spray gun first in treatment process, then the zinc leaching residue collected and the reducing agent to be added, slag former are added by fuming room feed opening and dilution room feed opening, make sulfonium agent and is handled in side-blown converter, it is 1000~1150 DEG C that the indoor temperature of fuming is controlled in treatment process, and the indoor temperature of dilution is 1150~1250 DEG C；The metallic vapour generated in processing is discharged after entering the air oxidation that gas phase zone is entered by overfiren air port by the smoke outlet of side-blown converter furnace roof, and valuable metal is trapped by matte and is discharged with matte, and remaining clinker is tiltedly exported discharge by slag.The present invention is simple using the small dual chamber Double bottom side-blown converter processing zinc leaching residue technological operation of occupied area, reduces the slag valuable metal content of output, improves the rate of recovery of valuable metal, reduces and change part pollution. |
