Abstract

The system includes a raw material predrying kiln, a preheating kiln, a reduction rotary kiln, a cooling rotary kiln, a ball mill, a magnetic separator, a reduced iron powder drying kiln, a blank prefabricator, a blank drying kiln, a sintering furnace, a fused salt electrolysis tank, a titanium cleaning device, a filtering device, a vacuum dryer, a waste heat boiler, and a steam turbine generator. In the present disclosure, a high-temperature flue gas produced by the reduction rotary kiln is directly used to preheat a raw material. The CO-containing high-temperature flue gas discharged by the reduction rotary kiln and the CO discharged at the fused salt electrolysis stage are recovered and used for power generation and steam production of the waste heat boiler. Due to a low moisture content of the flue gas, a low-temperature flue gas obtained after the waste heat recovery is used for drying.
