摘要（英）：

The utility model provides equipment for smelting lead and zinc by bottom blowing smelting and electrothermal reduction. The equipment comprises an oxygen-enriched bottom blowing smelting furnace, an ore-smelting electric furnace and a zinc rain condenser, wherein the oxygen-enriched bottom blowing smelting furnace comprises a smelting charging hole, a smelting smoke outlet and a melt discharge hole; the ore-smelting electric furnace comprises an electric furnace charging hole, a lead discharge hole, a slag discharge hole and an electric furnace smoke outlet; the charging hole of the ore-smelting electric furnace is connected with the melt discharge hole, so that the melt containing lead and zinc oxides discharged from the melt discharge hole flows into the ore-smelting electric furnace through the charging hole of the ore-smelting electric furnace; and an air inlet of the zinc rain condenser is connected with the electric furnace smoke outlet. According to the equipment for smelting lead and zinc by bottom blowing smelting and electrothermal reduction disclosed by the utility model, pollution on the environment can be alleviated; the yield of sulfuric acid is greatly improved; the melting process of the furnace charge is removed; and the electric consumption per unit product is also reduced.
