Abstract

The invention discloses a device for lead and zinc ore smelting. The device for lead and zinc ore smelting comprises an oxidization smelting furnace, a power frequency electric heating reduction furnace and a zinc rain condenser; the oxidization smelting furnace is provided with a lead and zinc ore inlet, a fluxing agent inlet, a smelting flue gas outlet and a melt outlet, and melt contains zinc oxide and lead oxide; the power frequency electric heating reduction furnace is provided with a melt inlet, a reduction agent inlet, a liquid lead outlet, a furnace slag outlet and a zinc-containing flue gas outlet, and the melt inlet is connected with the melt outlet; and the zinc rain condenser is provided with a zinc-containing flue gas inlet, a liquid zinc outlet and a coal gas outlet, and the zinc-containing flue gas inlet is connected with the zinc-containing flue gas outlet. By means of the device, after being subjected to oxidization melting, the lead and zinc ore can be directly supplied to the power frequency electric heating reduction furnace in a high-temperature melt state, in the furnace body, the zinc oxide is reduced into metal zinc steam by high-temperature carbon, and liquid metal zinc is further obtained through condensation. The lead oxide entering the furnace body is reduced into liquid metal lead by high-temperature carbon, and the liquid metal lead and liquid metal lead slag composed of iron oxide, silicon oxide, calcium oxide, aluminum oxide, magnesium oxide and other oxides jointly descend into a settling chamber on the lower portion of a vertical shaft type power frequency electric heating furnace.

Description

technical field [0001] The invention relates to the field of metallurgy. Specifically, the present invention relates to equipment for smelting lead-zinc ore. Background technique [0002] Since lead and zinc resources are mostly symbiotic ores, they are generally sorted into lead concentrate and zinc concentrate after mining, and sent to lead smelters and zinc smelters for separate processing. Due to the difficulty of thorough separation, there is always a certain amount of zinc impurity in the lead concentrate, and a certain amount of lead impurity in the zinc concentrate. After smelting, the zinc fume produced by the lead factory needs to be sent to the zinc factory for treatment, and the lead and silver slag produced by the zinc factory needs to be sent to the lead factory for treatment. [0003] Therefore, the current lead-zinc ore smelting methods still need to be improved. Contents of the invention [0004] The present invention aims at solving one of the above te...
