And oxygen-enriched air, raw material is fully reduced.
Embodiments in accordance with the present invention, spray gun jack 122 is located on the side wall of body of heater 100.Thus, ejecta is directly sprayed
Into slag blanket, the stroke of ejecta is short, and is inserted relative to spray gun from top, and the Action of Gravity Field overcome needed for ejecta is small,
Pressure needed for injection is small.
Spray gun 300：Embodiments in accordance with the present invention, the spray gun 300 be inserted into spray gun jack 122 with by oxygen rich gas and
Reducing agent is blown into the slag blanket ZC in blowing area 120.It is understood that in order to ensure spray gun 300 by oxygen rich gas and go back
Former agent is blown into the slag blanket ZC of melt, and the length that spray gun 300 stretches into blowing area 120 is unsuitable long, the insertion blowing of spray gun 300 area
The parameter (depth in such as molten bath) that 120 specific depth can smelt according to electric heating dilution is set.
, wherein it is desired to which explanation, the substance classes that spray gun is sprayed into slag blanket ZC are not particularly limited, spray gun not only may be used
To spray into oxygen rich gas and reducing agent, appropriate concentrate miberal powder can also be sprayed into as needed, for example, the miberal powder of copper concentrate.Thus,
Accelerating reduction reacts, further dilution clinker while reducing matte grade.
Embodiments in accordance with the present invention, reducing agent can be solid reductant, liquid reducer or gaseous reducing agent.
In addition it is also necessary to further illustrate, the material of every lance ejection is not particularly limited, and can be oxygen-enriched
At least one of gas and reducing agent and optional concentrate miberal powder, i.e., one spray gun, can spray oxygen rich gas, reducing agent
With any one in concentrate miberal powder or wherein any two kinds of combination, or injection oxygen rich gas, reducing agent simultaneously
With concentrate miberal powder.The regulative mode of the species of the injecting substances of spray gun and the ratio of each material is not particularly limited, for example, can
Condition is carried out with the species of the aliment of the feeding pipe by adjusting spray gun and ratio, can also be by adjusting the spray in spray gun
The structure for penetrating pipeline is adjusted, and can also carry out condition by adjusting the quantity for the spray gun for spraying each material.
Embodiments in accordance with the present invention, the insertion angle of spray gun is not particularly limited, and those skilled in the art can root
It is adjusted according to production needs.According to some embodiments of the present invention, spray gun 300 is straight at 0-30 degree angles.Specifically, spray
Rifle 300 is downwards that level is downward into 0-30 degree angles, the i.e. opening of angle with level, so that, ejecta sprays downwards, with slag blanket
In material good mixing effect.According to the preferred embodiment of the present invention, spray gun 400 is straight at 0-15 degree angles.Thus,
The ratio that ejecta enters slag blanket is high, prevents that the spray angle of ejecta is excessive, ejecta is entered matte layer, thus ejecta with
The mixed effect of material in slag blanket is more preferably.
Embodiments in accordance with the present invention, spray gun 300 further comprises：Threeway jet pipe, the threeway jet pipe is arranged on spray gun 300
Gun body in, and threeway jet pipe seals by ball valve.Thus, air port can be disclosed with hammer drill, no spray gun can be used very easily
Drill rod is blocked.
Electrode 500：Embodiments in accordance with the present invention, the electrode 500 is inserted into electrode jack 131 and extend into decanting zone
In interior slag blanket ZC.Thus, electrode is that decanting zone carries out heat supply, decanting zone cooling influence sedimentation separation effect is prevented, so as to have
The rate of recovery of valency metal is higher.
Embodiments in accordance with the present invention, electrode jack is multiple, that is to say, that may be inserted into multiple electrodes.Thus, it is heavy
Drop area and sufficient heat is provided, to prevent slag and sulfonium body from solidifying, influence sedimentation.
