The utility model discloses an oxygen enrichment side-blown dual-zone smelting furnace, which comprises a hearth, a furnace body, a water jacket, a charging opening, a slag tap and a discharging hole, wherein the hearth has a deep and shallow structure and is divided into a smelting zone and a fuming zone by an intermediate partition wall. The structure of the oxygen enrichment side-blown dual-zone smelting furnace is improved, so smelting and fuming can be performed in the same furnace in the smelting process; thus, the integral equipment is efficient, energy-saving and environment-friendly.
Description
Technical field
The utility model relates to a kind of bath smelting furnace of Non-ferrous Metallurgy industry, specifically is a kind of plumbous oxygen-enriched side-blowing two-region smelting furnace of smelting and handling leaded cadmia material that is used for.
Background technology
Directly lead smelting technology has the Ao Simai secret service of kivcet technology, QSL technology, Kaldo converter, oxygen-enriched top blowing to plant at present, and SKS lead smelting process, oxygen-enriched side-blowing technology are used to replace traditional sintering-blast furnace refining splicer skill.Up to the present the application of oxygen-enriched side-blowing stove refining plumbing only is used for retailoring.
Look into newly and show; The report that oxygen-enriched side-blowing stove and oxygen-enriched side-blowing two-region stove are arranged does not still have the report of the two-region stove of oxygen-enriched side-blowing cupola well branch depth structure, and existing oxygen-enriched side-blowing stove and oxygen-enriched side-blowing two-region stove all are that to be used for directly refining plumbous; The cupola well in two zones of two-region stove is at a sea line; Be respectively applied for oxidizing semlting and retailoring, and fuming need be carried out in other fuming furnace, can not solve the problem that melting and fuming are carried out in same stove.
The utility model content
The utility model is intended to overcome the deficiency that melting and fuming can not be carried out in the existing plumbous smelting technology in same stove; A kind of oxygen-enriched side-blowing two-region smelting furnace that melting and fuming are carried out in same stove is provided; Adopt oxygen-enriched side-blowing two-region smelting furnace refining lead can reduce fuming furnace slag input link; Eliminate the problem that fuming furnace is interrupted operation, have advantages such as environment is good, energy consumption is low, operation is continuous, labour intensity is low.
For achieving the above object, the technical scheme that the utility model proposes is:
Oxygen-enriched side-blowing two-region smelting furnace, it comprises cupola well, shaft, water jacket, charging opening, slag notch, drain, is characterised in that: midfeather is divided into smelting zone and fuming district with oxygen-enriched side-blowing two-region smelting furnace, and smelting zone and fuming district are communicated with through the partition wall lower passage.
In the cupola well of smelting furnace bottom the end of smelting zone lower than the end in fuming district, promptly the cupola well in two of the two-region stove zones at a sea line, is not respectively applied for melting and fuming; The lower end, smelting zone is communicated with lead bullion siphon escape orifice, and lower end, fuming district is communicated with slag siphon chamber.
The working process of the utility model is: liquid charging opening is added to the smelting zone of oxygen-enriched side-blowing two-region smelting furnace to the high lead slag of oxidizing semlting stove output continuously from the smelting zone through chute; Solid material charging opening adds in the stove continuously from the smelting zone for flux, reductive agent; Oxygen-rich air blasts the melt from a tuyere of both sides, smelting zone; High lead slag is reduced and generates slag and lead bullion, and lead bullion is emitted from the siphon escape orifice continuously, and slag flows into the fuming district through the partition wall lower passage.Charging opening adds cold burden from the fuming district, and oxygen-rich air and coal blast the melt from a tuyere of Yan Qu both sides respectively, and metals such as the zinc in the melt are reduced and get in the flue gas, and slag flows into slag siphon chamber, discharges continuously from slag-drip opening.The high-temperature flue gas in smelting zone and fuming district gets into the waste heat boiler recovery waste heat respectively, gathers dust advancing bagroom, and last simple process gets final product emptying.The flue dust that the fuming district reclaims mainly is ZnO, therefore can be used as product, the flue dust Returning smelting of smelting zone.
The beneficial effect that the utility model is brought by technique scheme is:
1, midfeather is divided into smelting zone and fuming district with oxygen-enriched side-blowing two-region smelting furnace; Oxygen-enriched side-blowing two-region smelting furnace can make melting and the different zones of fuming in same stove carry out; Reduce fuming furnace slag input link in the plumbous process of refining, eliminated the problem that fuming furnace is interrupted operation.
2, the end of smelting zone, is lower than the end in fuming district in the cupola well of smelting furnace bottom, and the lower end, smelting zone is communicated with lead bullion siphon escape orifice, and lower end, fuming district is communicated with slag siphon chamber.After the melting, lead bullion or lead matte sink at the bottom of the pond, cupola well molten bath, smelting zone, emit through the siphon escape orifice, slag flow into the fuming district further reduction carry zinc, fuming district slag flows into slag siphon chamber and emits continuously, efficient recovery valuable metals such as zinc, silver, indium, lead, copper.
3, copper water jacket is adopted at position, the utility model oxygen side blown converter molten bath, makes furnace campaign extend to 8～10 years, reduces the cost of stop production to overhaul, and production operational availability increases substantially.
4, the utility model device processes ability is big, and the bed ability reaches 60～80t/m
2.d, floor space is little, has environmental protection, energy-conservation, the recovery rate of valuable metals advantages of higher.
In general, the said oxygen-enriched side-blowing of the utility model two-region smelting furnace is through to structural improvement, makes that entire equipment is efficient more, energy-saving and environmental protection.
