Abstract

The invention relates to zinc concentrate smelting equipment which comprises an oxygen bottom blowing melting furnace, a side-blowing reduction furnace and a liquid metal condenser, wherein the oxygen bottom blowing melting furnace is provided with a feeding hole, a flue gas outlet, a melt outlet and an oxygen injecting hole arranged at the bottom; the side-blowing reduction furnace is provided with a melt feeding hole, a zinc-containing flue gas outlet, an oxygen and reducing agent injecting hole formed on the side surface and a slag outlet, wherein the melt feeding hole is connected with the melt outlet of the oxygen bottom blowing melting furnace; the liquid metal condenser is connected with the zinc-containing flue gas outlet of the side-blowing reduction furnace to be used for condensing zinc in zinc-containing flue gas. The zinc concentrate smelting equipment can realize clean production and also simplify a technological process, thereby lowering the capital investment and the production cost and particularly and greatly saving the energy and reducing the emission.

Description

technical field [0001] The invention belongs to the field of nonferrous metal smelting, in particular to a zinc concentrate smelting equipment. Background technique [0002] The traditional pyrometallurgical zinc smelting needs to oxidize and roast the zinc concentrate first, then add coal powder to the calcined sand, knead and press it into agglomerates, the agglomerates are preheated by coking in the coking furnace, and the hot agglomerates and the coke preheating furnace are preheated Hot coke at >800°C is added to the distillation furnace together to produce crude zinc. The process is long, energy-intensive, and the working environment of pressing and coking is harsh. This process has been completely eliminated in foreign countries. If the lead-zinc concentrate is smelted, the lead-zinc blast furnace smelting method (Imperial Smelting Process, hereinafter referred to as ISP) is used. Moreover, the use of lead-zinc blast furnace smelting requires the use of fuming fu...
