Energy-saving environment-protecting secondary lead multi-chamber metal smelting furnace and treatment method

Abstract

The invention discloses an energy-saving environment-protecting secondary lead multi-chamber metal smelting furnace and a treatment method and belongs to the technical field of secondary metal smelting. A furnace shell is mounted on a furnace foundation; a smelting furnace device and a gasification furnace are connected into a whole; a furnace steel frame is disposed outside the furnace shell to tightly hoop the furnace shell; a refractory material furnace building body is disposed on the inner side of the furnace shell; the smelting furnace device communicates with the upper portion of the interior of the gasification furnace through a smoke channel; liquid slag chutes are disposed between the smelting furnace device and the gasification furnace; the two ends of the liquid slag chutes communicate with liquid slag outlets of the smelting furnace device and liquid slag inlets of the gasification furnace correspondingly; smoke outlets are formed in the smelting furnace device and communicate with flues; and flue gates are disposed on the flues. The two sides of the top of the gasification furnace are connected with the flues of smelting furnaces, straight flowing of liquid hot slag can be achieved, the flues mutually communicate, the gates are opened and closed to control the smoke flowing direction so as to perform smelting, gasification, heat preservation and pre-heating on materials, continuous material feeding is performed during production, continuous melting is performed, latent heat of the liquid slag and waste heat of the smoke are utilized, the environment-protectingeffect is good, and the economic benefits and social benefits are remarkable.

Description

technical field [0001] The invention relates to the technical field of metal smelting, in particular to an energy-saving and environment-friendly recycled lead multi-chamber metal smelting furnace and a processing method. Background technique [0002] Non-ferrous metal smelting technology is gradually developing towards high efficiency, energy saving, environmental protection and continuity. Domestic and foreign non-ferrous metal smelting enterprises are actively seeking or developing smelting processes with large production capacity, low investment and operating costs, continuous operation, and environmental protection. Focus on the research and development of smelting equipment and smelting technology with independent intellectual property rights. [0003] At present, primary lead smelting methods at home and abroad mainly include sintering-blast furnace smelting, submerged top-blown Ausmelt (Ausmelt) smelting-blast furnace reduction, oxygen top-blown Kaldo (Kaldo) convert...

AI Technical Summary

Problems solved by technology

Most of the existing smelting processes have problems such as poor continuity of production process, low thermal efficiency, small scale of single furnace, high cost, low lead yield, and high content of valuable metals in slag, which will not only cause waste of resources, but also cause damage to the ecological environment. severe pollution
