Description
Technical field
The utility model belongs to metal smelt, relates in particular to the plumbous device of a kind of refining.
Background technology
The lead-smelting method that exists has at present: traditional sintering machine-blast furnace flow process, oxygen bottom-blowing-blast furnace reduction, QSL method, top blast submergence smelting process, kaldo process, basic husband's Saite method etc.In traditional sintering machine-blast furnace flow process, the SO 2 from fume concentration of generation is very low, adopts the relieving haperacidity of the single commentaries on classics of unstable state single suction, and conversion ratio has only 80%, and exhaust emissions does not still reach environmental requirement.Oxygen-enriched bottom-blowing melting-blast furnace reduction the lead smelting process of domestic comparative maturity, the high lead slag melt of generation is cast bulk through the cooling of casting slag system, and reduction melting in blast furnace then makes that the heat in the liquid high lead slag can not directly utilize, and causes energy waste.Other several lead-smelting methods, though well solved environmental issue in the plumbous smelting process, the implementation cost height, capital expenditure is big, deficiency in economic performance.Be applied to industrial production bigger limitation is all arranged.Base husband Saite method refining lead is the oxidation of finishing metal sulfide in flash smelting furnace, then the lead skim fused mass is moved on to reduce in the another set of device electric furnace and separates with clarifying.Equipment is huge, and power consumption is very high, and slag is plumbous high, the investment cost height, and the running cost height, very uneconomical.
Summary of the invention
The purpose of this utility model provides the plumbous device of a kind of refining simple in structure, easy and simple to handle, that energy consumption is low, pollution is few.
For achieving the above object, the utility model adopts following technical scheme: the plumbous device of a kind of refining, comprise body of heater, cupola well is arranged at the body of heater bottom, and spray gun is equipped with at the body of heater top, the body of heater top adds Jiao Kou in addition, a plurality of blast pipes are arranged at the body of heater bottom, and slag tap is arranged on the cupola well, and siphon lead tap is arranged at the cupola well bottom, the cupola well bottom also has the safety mouth, in the joint of body of heater and cupola well floss hole is arranged.
Described spray gun is made up of furnace charge nozzle and oxygen jet, is positioned at the middle position at body of heater top.
The described Jiao Kou of adding has one at least.
On the described blast pipe oxygen hose is arranged.
Characteristics of the present utility model are to finish the plumbous oxidation of refining, reduction overall process by a stove, and technology is succinct, belongs to short flow process.With existing refining splicer process flow ratio, have reduced investment, take up an area of less, advantage such as environmental protection.Through contrast test, use the utility model, dust rate in the production can reduce 17%～67%, the slag lead content reduces by 16%～67%, and the unit product comprehensive energy consumption reduces by 18%～36%, and coke consumption reduces by 34%～62%, that is to say, both energy-saving and cost-reducing, reduced disposal of pollutants again, have good economic and social benefit.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 looks schematic diagram for the left side of Fig. 1.
The specific embodiment
The plumbous device of refining as shown in Figure 1 and Figure 2, comprise body of heater 9, cupola well 6 is arranged at the body of heater bottom, and spray gun is equipped with in body of heater center of top position, spray gun is made up of furnace charge nozzle 1 and oxygen jet 2, the body of heater top adds burnt mouthful 3 in addition, and slag tap 8 is arranged on the cupola well, also has a plurality of blast pipes 5 on the cupola well, the air blast mouth of pipe is higher than slag tap 8, siphon lead tap 11 is arranged on the cupola well, and the cupola well bottom also has safety mouth 7, in the joint of body of heater 9 and cupola well 6 floss hole 4. is arranged
In view of the utility model sprays into furnace charge in the body of heater with spray gun, reaction speed is fast, has the air blast structure in conjunction with it again, so the inventor is called the flash blast furnace with the plumbous device of this refining, abbreviates as to dodge the drum stove.
Use this lead-smelting method that refines plumbous device to be: concentrate, flux to be dried to moisture content through steam dryer to be not more than 1%, again behind mix, furnace charge nozzle by spray gun sprays into from upper of furnace body, with the oxygen generation oxidation reaction that sprays into by the spray gun oxygen jet, generate lead oxide rain and SO
2Flue gas.The lead oxide red-hot coke layer that drops down onto 1200 ℃ to 1300 ℃ that rains carries out reduction reaction, generates metallic lead and CO and CO
2Two elementary reaction equations are as follows:
Oxidation panel: 2PbS+3O
2→ 2PbO+2SO
2
Reduction section: 3PbO+2C → 3Pb+CO+CO
2
PbO+CO→Pb+CO
2
Finish the slag making reaction of iron, silicon, calcium oxide simultaneously at the red-hot coke layer.Slag with plumbous through dodge the heavy sorting of bulging stove from after, put lead continuously by siphon port, and, finish the lead smelting overall process by the regular slagging of cinder notch.
Characteristics of the present utility model are to dodge bulging stove and finish lead oxide melt that oxidation reaction generates and evenly fall on the red-hot coke layer of body of heater bottom with the form of plumbous rain.Owing to be evenly distributed, reduction reaction is fully carried out, and can obtain higher lead recovery and lower lead-in-dreg.
Another characteristics of the present utility model are to adopt the coke preheating stove that coke is preheated to 1000 ℃～1100 ℃ adding sudden strain of a muscle drum stoves again.Send into oxygen-enriched air and the burnt reaction of heat at the crucible zone that dodges the drum stove, keep crucible zone and satisfy lead oxide reduction and required 1200～1300 ℃ temperature of slag making.Reaction temperature is controlled by the blow rate required, reduces the exhaust gas volumn and the dust rate of stove again to greatest extent.
The inventor uses the utility model to produce as a trial: institute's water content is not more than 1% after the concentrate drying machine drying, wherein plumbous composition 39%-62%, sulphur 16%-24%, lead-in-dreg after the reduction is between 1.0%-2.0%, dust rate is 5%-10%, and vertical yield is 90%, and lead recovery is 96%, unit product comprehensive energy consumption 360-440Kg mark coal/ton is plumbous, coke consumption 160-250Kg/ ton lead.
And produce in existing bottom convertor-blast furnace system with identical raw material, dust rate 12%-15%, the leaded 2.2%-3.0% of blast furnace slag, unit product comprehensive energy consumption 440-560Kg mark coal/ton is plumbous, coke consumption 380-420kg/ ton lead.
Through contrasting as seen, use the utility model, dust rate in the production can reduce 17%～67%, the slag lead content reduces by 16%～67%, and the unit product comprehensive energy consumption reduces by 18%～36%, and coke consumption reduces by 34%～62%, that is to say, both energy-saving and cost-reducing, reduced disposal of pollutants again, have good economic and social benefit.
