Charging opening 1012 places are provided with sanitary ventilation chamber and dust-removal system, to prevent the excessive of flue gas and dust.Slag notch 1013 places are provided with sanitary ventilation chamber and dust-removal system, to prevent the excessive of flue gas and dust.Put tin mouth 1014 places and be provided with sanitary ventilation chamber and dust-removal system, to prevent the excessive of flue gas and dust.
As shown in Figure 3, in examples more of the present invention, side-blown tin metallurgy device 10 can also comprise waste heat boiler 102, and waste heat boiler 102 has vertical uplift section 1021, vertical uplift section 1021 is integrally formed with Reaktionsofen 101, and vertical uplift section 1021 is connected with smoke outlet 1016.Can utilize thus waste heat boiler 102 to reclaim the heat in the flue gas that retailoring, strong retailoring and sulfiding volatilization process produce.And, by vertical uplift section 1021 and Reaktionsofen 101 are integrally formed, thereby can prevent that flue dust is bonding, so that the tin metallurgy device 10 that can make to blow side can steady in a long-term move.
Particularly, have cavity 10211 in vertical uplift section 1021, cavity 10211 is communicated with smoke outlet 1016.
Side-blown tin metallurgy device 10 also comprises dust-precipitator (for example bagroom), described dust-precipitator can be connected with described waste heat boiler, to utilize described dust-precipitator to reclaim the stanniferous flue dust in the flue gas that retailoring, strong retailoring and sulfiding volatilization process produce.
Side-blown tin metallurgy device 10 may further include water cooler, and described water cooler can be connected with described waste heat boiler and described dust-precipitator can be connected with described water cooler.
Wherein, stanniferous flue dust can join in furnace chamber 1011.In the time starting to start side-blown tin metallurgy device 10, owing to not producing stanniferous flue dust, therefore stanniferous material and flux can be joined in furnace chamber 1011.After stanniferous flue dust to be generated, stanniferous flue dust, stanniferous material and flux can be joined in furnace chamber 1011.
Can realize regular tin metallurgy, regularly arrange tin and regular deslagging according to the side-blown tin metallurgy device 10 of the utility model embodiment.
Be according to the technical superiority of the side-blown tin metallurgy device 10 of the utility model embodiment and side-blown tin-making process:
1, energy consumption is low: realized fusion process from tin material to thick tin and the sulfiding volatilization process of lean tin slag in stove the inside, fusion process adopts industrial oxygen (carrier of oxygen volume concentrations 30%-100%), exhaust gas volumn is few, dust rate is low, adopt broken coal (beans) as reductive agent, do not need relatively costly metallurgical coke, reclaim the waste heat in retailoring, strong retailoring and sulfiding volatilization process flue gas simultaneously.
2, environmental protection is good: tin concentrate fusion process carries out in an airtight Reaktionsofen 101, avoid flue gas to escape, tin concentrate or other tin raw material coordinate granulate after directly into stove, material preparation process is simple, in production process, the tin flue dust of output all seals and carries and return batching, has effectively prevented the disperse of tin dirt; The flue gas of melting and sulfiding volatilization output, after waste heat recovery and gathering dust, send desulphurization system.The thick tin of side-blown converter retailoring section and strong retailoring section output is discharged from putting Xi Kou, and the waste of sulfiding volatilization output is discharged from slag notch, simultaneously at charging opening, put Xi Kou and slag notch is established ventilating chamber, prevent the diffusion of tin steam.Substantially solved the problem of tin flue gas during smelting, tin dust pollution.
3, the rate of recovery is high: in side-blown tin metallurgy stove, owing to having utilized fully the heat content of slag, fusion process adopts industrial oxygen, and uses beans to effectively reduce exhaust gas volumn and dust rate, reduced the tin content in slag as reductive agent, has improved direct yield and the rate of recovery of tin.
4, side-blown sn smelting method is in all tin metallurgy methods, comprises material preparation system, the technique that flow process is the shortest, and process unit is simple, reduced investment.
