A recovery device for preparing nickel sulfate from organic complex nickel waste residue

Abstract

The utility model provides a kind of recovery device for preparing nickel sulfate with organic complex nickel waste residue, wherein recovery device includes ball mill, reaction kettle, centrifuge and high temperature furnace, reaction kettle includes reaction kettle body and jacketed heat exchanger and stirring device, reaction kettle body is provided with reaction kettle feed inlet, reaction kettle discharge port and back feed port, centrifuge is provided with centrifuge feed inlet and centrifuge residue outlet;High temperature furnace is provided with high temperature furnace feed inlet and high temperature furnace discharge port, high temperature furnace feed inlet is connected with centrifuge residue outlet by pipeline, and high temperature furnace discharge port is connected with the back feed port by pipeline.The utility model uses the method of oxidation and breakage combination calcination, process is simple, device structure is simple, it solves that the ability of anti waste nickel slag composition fluctuation is weak, reduces the influence of organic matter and each impurity to product, and using simple equipment and process can realize that waste residue containing organic complex nickel produces nickel sulfate, and can improve the content of produced nickel sulfate.
