Environment friendly system for smelting copper and copper alloy

Abstract

The invention belongs to the copper alloy processing field. Aiming at that a larger space is provided between a smelting furnace and a dust cover separated with each other in the prior art, when using partial scrap copper and even the entire scrap copper to smelt copper or copper alloy, the pollution is serious and the useful materials in the dust are wasted, an environmental protection system of copper and copper alloy smelting of the invention is adopted. The useful materials in the dust are recovered, the working environment of smelting is greatly improved and the waste gas exhausted by smelting is superior to the current national industrial waste gas emission standard. The system consists of a smelting furnace (1), a lower gate of the dust cover (2), an upper gate of the dust cover (3), a dust cover (4), a dust collector cyclone (10), a powder collecting box (11), a pipeline (5), a pulsed jet cloth filter (6), a dust box (9), an induced draft fan (8), a vent pipe (7), a slag drop channel (12), a slag connecting box (13) and an operations area (14). The system is also suitable for the environmental protection systems of other nonferrous metal and ferrous metal smelting.

Description

technical field [0001] An environmental protection system for smelting copper and copper alloys belongs to the field of copper material processing. Background technique [0002] In the existing copper and copper alloy melting and casting technology, the general smelting furnace is a tilting furnace with a rotatable shaft, and the smelted alloy melt is poured into a tundish or a holding furnace for further processing. Therefore, the fume hood above the smelting is generally separated from the smelting furnace, and there is a large space between the two to facilitate workers' operations, such as adding alloy material, adding covering agent, adding scouring agent, scooping slag, pouring alloy melt, etc. . Therefore, in the actual production process, especially when the raw materials contain some scrap copper or all of it is scrap copper, because the scrap copper is accompanied by a large amount of other low-melting point metals, inorganic non-metallic compounds, organic substa...
