Background technology
Nickel smelting waste slag, copper smelting waste slag, nickel, copper, cobalt smelting waste slag are a kind of solid slag of discharging during non-ferrous metal metallurgy is produced, a kind of iron and steel resource of uniqueness especially.Not only contain a large amount of ferrous metals and silicon-dioxide in these wastes, and also have metal, non-metallic elements such as minor amount of nickel, copper, cobalt, lead, zinc, the nickel smelting waste slag of enormous amount, copper smelting waste slag, nickel, copper, cobalt smelting waste slag are done the additive replacement iron ore for the cement mill except that a small amount of at present, and all the other all do not obtain development and use.Temperature is at 1100 ℃-1300 ℃ when pyrogenic process nickel, copper, cobalt smelting waste slag discharging.Sensible heat during the slag discharging is not utilized effectively, and has caused a large amount of thermal waste.If the sensible heat when making full use of nickel, copper, the discharging of cobalt waste, to the warm sludge purification and impurity removal, obtain comparatively purified ferrous metasilicate, nickel, copper, the cobalt waste of serious environment pollution are turned waste into wealth, fully utilized resource to greatest extent, not only meet national industrial policies, and save energy, reduce and pollute, for energy-saving and emission-reduction, developing a circular economy has great realistic meaning.
At present, reclaiming metal from nickel, copper, cobalt waste has several different methods, and wherein commonly used have the hot method of charcoal, fuming process, electric dilution method, a flotation process etc., utilizes nickel, copper waste to reclaim ferrous metal, and existing abroad proven technique technology is used for reference.But up to the present, these technical matters processing costs are too high, and economic benefit is too poor.Especially aspect saving energy and reduce the cost, various economic targets are very poor, and therefore, this technology does not have practical value so far.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of uniqueness simple in structure, safe and reliable, can make full use of a kind of equipment that utilizes the non-ferrous metal metallurgy waste to produce and use in the ferrous metasilicate removal of impurities reaction that nickel smelting waste slag, copper smelting waste slag, nickel, copper, cobalt smelting waste slag, save energy, minimizing pollute.
The utility model is realized in the following way:
A kind of equipment that utilizes the non-ferrous metal metallurgy waste to produce and to use in the ferrous metasilicate removal of impurities reaction, it comprises the warm sludge bag, it is characterized in that: this warm sludge is wrapped the equipment that can move freely and can go deep into the importing gas of its bottom that is provided with;
The equipment of described importing gas is by forming by telescopic joint high temperature resistant, a corrosion resistant airway and the gas jet of airway end on a flexible gas duct that has a gas switch, the gas duct;
Described flexible gas duct is a rubber hose, and described airway is the plain pipe of graphitized charcoal;
The cross section of described warm sludge bag inner bottom part is a trilateral.
The utility model has following effect:
1) simple in structure, unique, save energy, minimizing are polluted: the equipment that the utility model provides is that the sensible heat when making full use of nickel, copper smelting waste slag discharging carries out electric furnace insulation heating measure to warm sludge, make warm sludge keep certain temperature, and have good fluidity and chemically active warm sludge bag, high pressure oxygen, high pressure chlorine can be blown among the warm sludge, make detrimental impurity in itself and the warm sludge such as aluminum oxide, magnesium oxide, calcium oxide, sulfide etc., the equipment of the importing gas that fully reacts is formed.
2) high temperature resistant, corrosion-resistant, long service life: the equipment that the utility model provides is because the singularity of the gas that imports: thereby the equipment that imports gas is made up of the gas jet of the end by telescopic joint high temperature resistant, a corrosion resistant airway and airway on a flexible gas duct that has a gas switch, the gas duct, flexible gas duct is a rubber hose, airway is the plain pipe of graphitized charcoal, thereby this equipment is not only high temperature resistant, corrosion-resistant, and has prolonged the work-ing life of equipment.
3) can not introduce other impurity: the equipment that the utility model provides, because the part that the equipment of importing gas gos deep in the warm sludge bag is the plain pipe of graphitized charcoal, its major ingredient is a carbon element, thereby can not introduce other impurity.
4) sufficient reacting, can reclaim useful material fully: the equipment that the utility model provides, because the cross section of warm sludge bag inner bottom part is a trilateral, detrimental impurity in itself and the warm sludge is fully reacted, and because the reactant that generates is distributed in different layers according to different proportion, be the solid scum silica frost on upper strata, the liquid ferrous metasilicate at middle part, the end slag of lower floor, because the special shape of warm sludge bag thereby the end slag separate easily of lower floor.
5) end-use is extensive: the ferrous metasilicate that the device fabrication that the utility model provides goes out not only can be made into the block ferrous metasilicate of ball; Utilize the melting reduction technique the block ferrous metasilicate electric stove integral deoxidation and reduction of ball to be become the silicon au-alloy of microalloy character again.This ferrous metasilicate ball piece is a kind of product innovation, can be used for the production of ferro-silicon, both can substitute steel cuttings, iron scale, can also substitute silica, but also is a kind of grog.Can save energy and reduce the cost during use, not only can reduce the ferrosilicon production cost significantly, and can reduce emission of carbon-dioxide, have good efficiency of cycling economy and social environment benefit.This ferrous metasilicate can also use as the iron making and sintering furnace charge, has good efficiency of cycling economy and social environment benefit if use by a certain percentage.Therefore this ferrous metasilicate product has good market outlook.This ferro-silicon that utilizes ferrous metasilicate production is one of essential raw material of steel-making, also is one of the raw material that must use of production MAGNESIUM METAL, and existing market has good prospects.
6) rate of recovery height: the device processes nickel, copper, the cobalt waste that adopt the utility model to provide, the ferrous metal rate of recovery reaches 95%.Nickel, copper, the cobalt rate of recovery be 93%, the silicon rate of recovery 92%.
