The invention relates to an energy-saving high-efficient direct lead-
smelting comprehensive metallurgical device, which is formed by serially joining three melting bath
smelting furnaces: a first furnace, a second furnace and a third furnace; and the second furnace consists of a furnace cylinder and a furnace body which is arranged on the furnace cylinder. The top part of the upper furnace body is provided with a
smoke exhaust port and a standby feeding port; a charge feeding port and a
slag feeding port are arranged above the lower furnace body; and the bottom part of the lower furnace body is provided with a
slag siphonic water-collecting well. The furnace body is provided with three rows of supply-air outlets. The bottom part of the furnace cylinder is provided with a
metal siphonic outlet. Due to the adoption of the direct lead-
smelting comprehensive metallurgical device, the heat loss is small, the heat
utilization rate is high, sulfuric dioxide
smoke with
high concentration can be produced, and the requirement for producing the acid can be more favorably satisfied; and molten high-lead thermal
slag which is produced through oxidation and smelting directly flows into a reducing furnace, so the heat of the thermal
molten slag can be adequately utilized. The land occupied area is small, the investment can be saved, the heat loss is less, the heat
utilization rate is high, the
heat energy can be adequately utilized, a great amount of
energy consumption can be saved, output of
smoke is small, the content of harmful ingredients in smoke is low, and the environmental
pollution problem can be more effectively solved.
