Reaction.Reducing agent used is one or more in natural gas, liquefied petroleum gas, ammonia, propane, fine coal, heavy oil, and copper liquid is embezzled
The Cu of sum2O is reacted with reducing agent generates Cu.
In step S105, when reducing agent such as natural gas, liquefied petroleum gas etc., melted through restoring 61 continuous high speed of spray gun and spraying into
When pond carries out reduction reaction, the combustible gas such as CO that reducing zone generates burns, the heat of releasing adds when flowing through zoneofoxidation 101
To utilize, energy consumption can be reduced.In addition, reducing agent can also be blasted together into stove by restoring spray gun 62 and will not be reacted with copper
Gas, as nitrogen or inert gas improve mass-and heat-transfer condition, strengthening smelting response intensity to stirring melt.
In step s 106, the copper liquid after reduction is flowed continually out by the copper mouth of putting of reducing zone 102, flows out it in copper liquid
Before, the oxygen content of the copper liquid after control reduction is 0.05-0.2%.The flue gas of generation is with the flue gas of zoneofoxidation 101 from outlet flue 3
It is discharged together.Since oxidation, reduction reaction are carried out continuously, continuous-stable, flue gas continuous-stable are reacted, and exhaust gas volumn is small, solution
Having determined, traditional refining furnace exhaust gas volumn fluctuation is big, and smoke components each stage also differs the problem of bringing.
In conclusion the blister copper pyrogenic process continuous refining process of the present invention can realize the melting continuously from blister copper to anode copper,
Oxidation, reduction reaction process are carried out at the same time when operation, and exhaust gas volumn is small, can shorten the activity duration, are improved utilization rate of equipment and installations, are effectively solved
Certainly SO2In serious pollution problem caused by smoke discharge amount is big and traditional handicraft the problem of blister copper involucrum cold burden.Exhaust gas volumn simultaneously
Relatively stablize with smoke components, the combustible fumes that reducing zone generates oxidized area can be burnt secondary use before discharging, make reduction cigarette
Gas waste heat is effectively utilized, and can be significantly reduced than traditional work without casting and empty stove soak, energy consumption in short-term.
In short, the blister copper pyrogenic process continuous refining furnace of the present invention has low energy consumption, environmental-friendly, automatization level is high, production efficiency is high etc.
Advantage.
