Abstract

The invention discloses a copper-based organic solid waste recycling, reduction and harmless treatment device and a treatment method. The raw material adaptability and furnace condition adjustment capability of a top-side composite blowing molten pool smelting furnace are stronger, and the capability of an oxygen-enriched concentration increasing bed is improved; a top-side composite blowing molten pool smelting furnace-electric furnace double-furnace operation and soot valuable metal recycling technology is adopted to improve the copper and precious metal recovery rate and realize resource treatment of copper-based organic solid waste; and a top-side composite blowing molten pool smelting technology and a two-combustion-chamber flue gas combustion control technology are adopted for linkage control, self-heating smelting control, dioxin source reduction control and the low ash yield are realized, and reduction treatment of copper-based organic solid waste is realized. Secondary pollution is avoided, the emission standard of dioxin and other components in flue gas is high, a small amount of generated soot containing high zinc and lead is periodically opened, and the harmless treatment of copper-based organic solid waste is realized.

Description

technical field [0001] The invention relates to the technical field of solid waste recycling, reduction and pyrometallurgy, in particular to a copper-based organic solid waste recycling, reduction and harmless treatment device and treatment method. Background technique [0002] At present, copper-based solid waste such as waste circuit boards, electronic components, and miscellaneous copper are treated by pyrolysis mainly by blast furnaces, top-blown molten pool melting furnaces and side-blown molten pool melting furnaces. [0003] Blast furnace production is extensive, flue gas emissions are not up to standard, the recovery rate of valuable metals is low, and there are secondary pollution problems. [0004] Top-blown molten pool melting furnace processing circuit board has the characteristics of long furnace life, strong material adaptability and working condition adjustment ability, high recovery rate of non-ferrous metals and precious metals, and good environmental protec...
