CONTINUOUS LEAD SMELTING DEVICE AND CONTINUOUS LEAD SMELTING METHOD

摘要

Disclosed is a continuous lead smelting device, which includes a reaction furnace (1) and a separating wall (4) provided therein for dividing furnace chamber of the reaction furnace(l) into oxidation region (Y) and reduction region (H). A communicating channel (41) at the foot of the separating wall (4) communicates the oxidation region (Y) and the reduction region (H). A side-blowing spraying gun(2) of the oxidation region (H) is attached to the side wall of oxidation region (Y) of reaction furnace (1) to blow oxygen into smelting tank of oxidation region (Y) from one side. A side-blowing spraying gun (3) of the reduction region (H) is attached to the side wall of the reduction region (H) of the reaction furnace (1) to blow fuel and oxygen into the smelting tank of the reduction region (H). As the oxidation and reduction process is conducted in a single reaction furnace by using the continuous lead smelting device, the lead contained in the slag is reduced and the sealing performance of the continuous lead smelting device can be stably maintained. As the lead smelting device fully uses the thermal enthalpy of the slag, the energy consumption can be reduced. Also disclosed is a continuous lead smelting method.
