According to the copper matte regulus bottom blowing blowing technology of the embodiment of the present invention, by being blown into continuously oxygen-containing gas in the melt that utilizes Bottom Blowing Ejection Gun to blow in device to copper matte regulus bottom blowing from the bottom of described copper matte regulus bottom blowing blowing device, can realize continuous converting, raise the efficiency, reduce costs, and exhaust gas volumn is few, flue gas concentration is stable, and flue gas is overflowed few, good environmental protection, reduced pollution, blister copper quality is high, and in blowing slag, copper content reduces.
It will be appreciated that, refer to the interior oxygen-containing gas that is blown into continuously of furnace chamber 101: while normally production, uninterruptedly blow continuously oxygen-containing gas, can avoid damaging Bottom Blowing Ejection Gun 20, certainly,, in the time that copper matte regulus bottom blowing blowing device is made a fault or normally keeps in repair, Bottom Blowing Ejection Gun 20 also needs to stop blowing.
Periodically blow side compared with oxygen with traditional PS converter, unit time air output reduces, and unit time exhaust gas volumn is little, Heat stability is good, and cost and energy consumption are low, and efficiency is high.
In some embodiments of the invention, Bottom Blowing Ejection Gun 20 is blown into oxygen-containing gas in the copper matte regulus layer C2 in furnace chamber 101 continuously from the bottom of body of heater 10.By be blown into continuously oxygen-containing gas in copper matte regulus layer C2, can reduce the tilt angle of body of heater 10, improve the capacity utilization of body of heater 10, be convenient to safeguard Bottom Blowing Ejection Gun 20.
Advantageously, Bottom Blowing Ejection Gun 20 is blown into oxygen-containing gas in the blister copper layer C1 in furnace chamber 101 continuously from the bottom of body of heater 10.
As shown in Figure 1, in furnace chamber 101, melt can be divided into three parts (three-phase): blister copper layer C1, copper matte regulus layer (or claiming copper-nickel alloy sulfonium layer) C2 and blowing slag blanket C3, L1, L2 and L3 are respectively blister copper metal lines, copper matte regulus metal line and slag blanket metal line, the in the situation that of three-phase coexistence, be conducive to reduce slag cupric and security and improve.In other embodiment of the application, can pass through the accurate control to inlet amount and blowing oxygen quantity, the melt in converting furnace is existed with blister copper and blowing slag two-phase, there is no or almost do not have copper matte regulus layer (or claiming copper-nickel alloy sulfonium layer).For example, in these embodiment of the present invention, by accurately controlling the amount ratio of copper matte regulus and oxygen-containing gas (oxygen amount), melt in furnace chamber 101 can be also two portions (two-phase), blister copper layer C1 and blowing slag blanket C3, be that copper matte regulus enters the blowing of the interior i.e. quilt of furnace chamber 101 for blister copper and blowing slag, the in the situation that of two-phase coexistent, blister copper quality is high, and impurity is low.By this control, can further improve blowing effect, further reduce the sulphur content of blister copper and the content of other impurity (such as arsenic, antimony, bismuth, lead etc.).Owing to can accurately controlling the amount ratio of copper matte regulus and oxygen-containing gas, thereby can avoid too much causing blister copper peroxidation and forming foamy slag because oxygen-containing gas sprays into, can also avoid containing more impurity (such as arsenic, antimony, bismuth, lead etc.) so that subsequent disposal because oxygen-containing gas sprays into the very few blister copper that causes.
Be to the beneficial effect that blows oxygen-containing gas in blister copper layer: in described copper matte regulus bottom blowing blowing device, blister copper layer C1 is positioned at copper matte regulus layer C2 below, by oxygen-containing gas being blown into continuously to blister copper layer C1, described Bottom Blowing Ejection Gun is without passing blister copper layer C1, the life-span that can improve so described Bottom Blowing Ejection Gun.In other words, by be blown into continuously oxygen-containing gas in blister copper layer C1, can make described Bottom Blowing Ejection Gun for example, without stretching into too many (length that described Bottom Blowing Ejection Gun stretches in described furnace chamber can be less than 50 millimeters) in described furnace chamber, reduce the loss of described Bottom Blowing Ejection Gun, extend the work-ing life of described copper matte regulus bottom blowing blowing device, reduce the running cost of described copper matte regulus bottom blowing blowing device.In addition, the amount that oxygen-containing gas enters slag blanket reduces, and avoids because copper matte regulus layer C2 is thinner, the oxygen-containing gas of described Bottom Blowing Ejection Gun ejection is easy to enter slag blanket through copper matte regulus layer C2, thereby cause oxygen-containing gas waste, can reduce the consumption of oxygen-containing gas, further reduce costs.
And, by be blown into continuously oxygen-containing gas in blister copper layer, can make the oxygen gesture in blister copper layer the highest, and first impurity element (S, As, Sb, Bi, the Pb etc.) oxidation being mixed in blister copper layer be removed, thereby obtain the higher blister copper of quality.Oxygen-containing gas can also be using blister copper as carrier, with Cu 2cu in O, CuO form and copper matte regulus layer C2 2s, CuS reaction generates Cu and SO 2, and react generation FeO, SO with the FeS in copper matte regulus layer 2and Cu.Described copper matte regulus bottom blowing blowing technology can reduce Fe 3o 4growing amount, prevent Fe 3o 4the generation of precipitation and foamy slag.Due to the Fe in blowing slag 3o 4content is low, and the viscosity of blowing slag is just low, and then can reduce Cu in blowing slag 2the inclusion content (for example, the copper content of blowing slag can be less than 14%, is even less than 10%) of O.By be blown into continuously oxygen-containing gas in described blister copper layer, increase the oxygen-containing gas reaction times, improved oxygen-containing gas utilization ratio, improved blister copper quality.In addition, by be blown into continuously oxygen-containing gas in blister copper layer, the total amount of gas can be reduced to be blown in the unit time, thereby the risk of spray stove can be reduced.
