Reaction device of non-ferrous metal recycling

Abstract

The invention belongs to a non-ferrous metal smelting device and particularly relates to a reaction device of non-ferrous metal recycling, wherein the reaction device has simple structure and reasonable design and is low-carbon, energy-saving, efficient and environmentally-friendly. The reaction device comprises a rotatable furnace body, wherein one side of the rotatable furnace body is provided with a charging hole with a charging furnace door; the outside of the rotatable furnace body is provided with a refractory material and a furnace body steel shell in turn; the outside of the furnace body steel shell is provided with a rolling ring; the corresponding position of the rolling ring is provided with a rotatable riding wheel with an electric motor; the rotatable furnace body is providedwith a metal slag melt outlet; the other side of the rotatable furnace body is provided with a furnace gas outlet; the fuel gas tank is connected with a natural gas oxygen-enriched burner through a tee joint; the natural gas oxygen-enriched burner passes through a two-pass furnace to be communicated with the furnace gas outlet; and the top of the two-pass furnace is provided with a main flue. Thereaction device has the advantages of simple structure, reasonable design, convenient maintenance, energy conservation, high efficiency and environmental friendness.

Description

technical field [0001] The invention belongs to a nonferrous metal smelting device, in particular to a nonferrous metal recovery reaction device with simple structure, reasonable design, low carbon, energy saving, high efficiency and environmental protection. Background technique [0002] my country's secondary lead industry started in the 1950s, and the output and technology of the current secondary lead industry are far behind those of western developed countries. First of all, the output of recycled lead in western developed countries accounts for more than 60% of the total output, while that in my country is less than 20%. However, most of the traditional methods for recycling lead in waste batteries and copper dross produced by lead smelting in China are recovered by reverberatory furnace or converter, mainly using traditional small reverberatory furnace, blast furnace and cupola and other smelting processes. , The grid and lead mud are mixed together, and some small ent...

Problems solved by technology

[0003] Using air as a combustion aid and medium, heating to reach a high temperature, so that the smelted material is melted and refined. This method: 1. The utilization rate of heat is extremely low, resulting in a waste of energy; 2. The processing capacity is small and the operation cycle Long, the labor intensity of workers is high, only suitable for small workshop production operations, 3, the labor production environment conditions are poor, can not meet the increasingly stringent requirements of environmental protection for modern industrial production
