A kind of polynary smelting furnace of continuous production Asia white metal of the invention compared with prior art, has oxidizing intensity It is high, degree of oxidation is deep, slag making thoroughly, efficiently, low consumption, low pollution continuous production Asia white metal the characteristics of, additionally have following Numerous significant advantages:

1, the oxygen-enriched air of oxygen-containing 73-75% is injected extensively into furnace by 23 Bottom Blowing Ejection Guns of two rows, violent oxidation reaction is released High energy heat is put, the material that instant melting enters keeps oxidation more thorough extensively further with oxygen close contact.It is horizontal The input of the setting of spray gun, especially natural gas, combustion process change clinker Fe₃O₄With F₃O ratio reduces slag viscosity, copper Sulfonium deferrization is more thorough, it is easier to generate the sub- white metal close to white metal.

2, the Bottom Blowing Ejection Gun of centrality jet stream and horizontal spray gun are set to the same side of furnace body longitudinal direction baseline, keep jet stream dynamic Power and the small range vortex of thermal convection power formation have an effect simultaneously with a wide range of eddy flow, generated stirring, blend and rush Collective effect is washed, for the deferrization for improving copper matte regulus, high copper ultimately forms sub- white metal and provides guarantee on sport dynamics.

3, the generation process of above-mentioned sub- white metal has shared the partial function effect of prior art converting furnace, straight for lower step It taps into and provides possibility into fiery smart furnace production anode copper.By generating the sub- polynary smelting furnace of white metal and the fire of melting Asia white metal Smart furnace shares the function of converting furnace, eliminates the converting process in Copper making process.

4, siphon, which is backflowed, puts the setting of sulfonium mouth, and the device for transporting copper matte regulus for undertaking has reserved drop space, reduces polynary The antenna height of smelting furnace, the corresponding setting height for also reducing workshop create condition for the convenience and safety of production operation, Also reduce capital construction cost.Higher guarantee is provided for continuous uninterrupted production anode copper production line.

Specific embodiment

The present invention is made to be described in detail further below in conjunction with Figure of description:

Polynary smelting furnace furnace body 1 of the invention is to be supported by fixing support rack 2 is fixed as shown in Figure 1:, is driven by annular rack 3 The dynamic cylindrical horizontal bottom-blown converter that can carry out lateral angles rotation, furnace body 1 having a size of Φ 5.5-28.8m, furnace body 1 above in The feed inlet 4 of section three longitudinal arrangements of setting, side end inside are arranged flue collector 7, auxillary flue are arranged on the inside of the end of the other side 8.Slag-drip opening 5 is arranged in the headwall middle and lower part of 7 side of flue collector, and sulfonium mouth 6 is put in the headwall bottom setting of 8 side of auxillary flue.In below furnace body 1 End is set as spray gun area.

As shown in Figure 1, Figure 2 and Figure 3, it is respectively set on 7 ° of the side line and 22 ° of lines of longitudinal baseline in spray gun area The Bottom Blowing Ejection Gun 9 of two rows of centrality jet streams, interior row 12, outlet 11, in ipsilateral middle and lower part, under the upper layer liquid level of copper matte regulus depth One row 3, the horizontal spray gun 10 of equidistant arrangement are set.

As shown in Figure 1 and Figure 4, the sulfonium mouth 6 of putting is to be opened on 1 bottom of furnace body, and backflowed upward copper by siphonage It is flat finally to rush down the steel sulfonium liquid that open height is slightly below in furnace body 1 for sulfonium channel.

As shown in Figure 1, shown in Figure 5, the cannula structure that the spray gun is inside and outside two layers, the tail end of Bottom Blowing Ejection Gun 9, internal layer connection Gas pipeline is supplied oxygen, outer layer connects air line.The tail end bull bifurcated of horizontal spray gun 10, be separately connected oxygen, air, nitrogen and Natural gas supply pipeline.

It produces in operation process, by more metal copper concentrates of the filling mixing of feed inlet 4, flux is controlled with dirt, center is returned Oxygen, air ratio and supply amount of the room according to quantity, property and furnace body temperature the regulation Bottom Blowing Ejection Gun 9 of charging, gas supply Oxygen concentration causes to fall and break mostly in 73-75% or so and stirs into the material in molten bath, and violent oxidation reaction, release high energy heat occur for moment Amount realizes autogenous smelting, and the temperature difference generated by the energy of the impinging jet and oxidation reaction of Bottom Blowing Ejection Gun 9 and horizontal spray gun 10, shape At the back vortex around spray gun and around the horizontal cyclone of furnace body 1, molten liquid is rinsed in blending stirring, promotes the depth of copper matte regulus Oxidation process, and the floating of the different sedimentations that copper matte regulus occurs and slag liquid because of specific gravity, while above-mentioned reaction, horizontal spray gun 10 Oxygen, air, nitrogen and the natural gas of regulation are headed into slag melt layer, improves slag properties, reduce ferroso-ferric oxide content, Iron oxide content is improved, slag melt, copper content is made to realize 3% or so, is discharged in copper matte regulus without ferro element remaining.Copper content is formed to reach To the sub- white metal of 75-78%.The interruption of slag-drip opening 5 is opened, and discharge clinker is transported to slow cooling field and carries out slow cooling processing, is continued uninterrupted Unlatching puts sulfonium mouth 6 and sub- white metal copper matte regulus is continuously discharged.The flue gas of generation rises, and flue collector 7 and auxillary flue 8 successively enter waste heat pot Furnace is sent to acid accumulator plant through high-temperature blower after electricity gathers dust.

The example of above-described embodiment Jin Xian our company production practices extends smelting furnace oxidation process, directly generation Asia Bai Bing The similar technique scheme of copper is also included within the protection scope of the claims in the present invention.

Except for the technical features described in the specification, remaining is that oneself of those skilled in the art knows technology.
