METHOD FOR SMELTING NON-FERROUS METAL SULFIDES IN A SUSPENSION SMELTING FURNACE AND SUSPENSION SMELTING FURNACE Field of the invention
The invention relates to a method for smelting non-ferrous metal sulfides in a suspension smelting furnace as defined in the preamble of independent claim 1.
The invention also relates to a suspension smelting furnace as defined in the preamble of independent claim 6.
The invention relates to a method that takes place in the suspension smelting furnace, such as a flash smelting furnace or a flash converting furnace, and to a suspension smelting furnace, such as a flash smelting furnace or a flash converting furnace.
Publication WO 2007/113375 relates to a method for treating solids-containing process gas in a suspension smelting furnace, comprising directing the process gas from the reaction shaft of the suspension smelting furnace to a settler and, further, through a raised shaft to a waste heat boiler to cool the process gas, whereby, through one or more gas nozzles placed on the settler top wall, oxidizing gas is fed into the process gas flowing in the settler, whereby the amount of oxidizing gas is adjusted during the process so that the amount of sulfides contained in the solid matter of the process gas that is directed to the waste heat boiler is minimized. Publication WO 2007/113375 relates also to equipment for treating solids-containing process gas in a suspension smelting furnace, wherein the process gas is directed from the reaction shaft of the suspension smelting furnace to the settler and, further, through the raised shaft to the waste heat boiler to cool the process gas. One or more gas nozzles are arranged on the top wall of the settler for feeding oxidizing gas into the process gas flowing in the settler, whereby the amount of oxidizing gas can be adjusted during the process so that the amount of sulfides contained in the solid matter of the process gas that is directed to the waste heat boiler is minimized.
Publication WO 00/70103 relates to a method and equipment, whereby matte with a high non-ferrous metal content and disposable slag are produced simultaneously in a suspensionsmelting furnace from non-ferrous sulfide concentrate. According to the invention, a carbonaceous reducing agent is charged to the settler of a suspension smelting furnace via tuyeres to the part of the furnace which has a reduced cross-sectional area.
Objective of the invention
The object of the invention is to provide a method for smelting non-ferrous metal sulfides in a suspension smelting furnace and suspension smelting furnace having improved blending of fluid and/or pulverous matter into process gases which are created in the reaction space of the suspension smelting furnace.
Short description of the invention
The method of the invention is characterized by the definitions of independent claim 1.
Preferred embodiments of the method are defined in the dependent claims 2 to 5.
The suspension smelting furnace of the invention is correspondingly characterized by the definitions of independent claim 6.
Preferred embodiments of the suspension smelting furnace are defined in the dependent claims 7 to 10.
The invention is based on arranging injection means for injecting at least one of fluid, such as liquid, for example small water droplets, and/or gas, for example technical oxygen, and pulverous matter, for example coal or coke powder, into the settler from at least one of the side wall structure of the settler so that at least one of fluid and pulverous matter is injected into the settler above the top surface of the layer of melt in the settler. By arranging injection means in this manner, fluid and/or pulverous matter fed by means of the injection means will be fed into the process gases in the settler and not into the melt in the settler with the result that the composition of the melt would be changed.
The invention can be used for different purposes in a suspension smelting furnace. The intended use depends on the furnace geometry, type of raw material to be smelted in the suspension smelting furnace and type of off-gas line i.e. type of system for processing process gases formed in the suspension smelting process after exiting the uptake shaft of the suspension smelting furnace.
One purpose is to oxidize residual sulfide particles in the dust created in the reaction shaft of the suspension smelting furnace into oxidic particles in order to easier create sulphate particles further down in the off-gas line.
Another purpose is to lower the temperature of the process gases which are created in the suspension smelting furnace and which are removed from the suspension smelting furnace via the uptake shaft.
Another purpose is to amend the composition of the particles in the process gases which are created in the suspension smelting furnace so that the particles, if and when, they stick to the inner walls of the settler or to the inner walls of the uptake shaft of the suspension smelting furnace and create build-up, the build-ups has a lower melting point compared to build-ups solely composed of particles in the process gases, i.e. melt away the buildup,.
Another purpose is to amend the composition of the particles in the process gases which are created in the suspension smelting furnace and the same time lower the temperature of the process gas so that the particles are in solid form in the gas phase temperature, which minimizes the sticking of the particles to the sidewalls of the uptake shaft.
List of figures
In the following the invention will described in more detail by referring to the figures, which
Figure 1 is a principle drawing of a suspension smelting furnace according to a preferred embodiment of the invention, and
Figure 2 shows the suspension smelting furnace shown in figure 1 as cut along line A-A in figure 1.
Detailed description of the invention
The invention relates to a method for smelting non-ferrous metal sulfides in a suspension smelting furnace and to a suspension smelting furnace.
The figures shows an example of a suspension smelting furnace according to a preferred embodiment of the invention
First the method for smelting non-ferrous metal sulfides such as sulfidic copper concentrate, sulfidic nickel concentrate, sulfidic zinc concentrate, or sulfidic matte, for example sulfidic copper matte, sulfidic nickel matte, or sulfidic zinc matte, in a suspension smelting furnace will be described in greater detail.
The method includes using a suspension smelting furnace comprising a reaction shaft 1, a settler 2 in communication with the reaction shaft 1 via a first communication point 3 that is formed between a lower end of the reaction shaft 1 and the settler 2, and an uptake shaft 4 in communication with the settler 2 via a second communication point 5 that is formed between the settler 2 and a lower end of the uptake shaft 4. The settler 2 comprises a bottom stmcture 6, a top wall structure 7, a first side wall structure 8 and a second side wall structure 9 between the bottom structure 6 and the top wall structure 7, and a first end wall stmcture 10 at one end of the settler 2 and a second end stmcture 11 at the opposite end of the settler 2.
The method included a feeding step for feeding by means of a concentrate burner 12 non-ferrous metal sulfides 13 and reaction gas 14 such as air, oxygen-enriched air or oxygen and possible also flux and/or fine dust into the reaction shaft 1 to have non-ferrous metal sulfides 13 and reaction gas 14 to react together in the reaction shaft 1 to produce melt (not shown or marked with a reference numeral).
The method includes also a collecting step for collecting melt from the reaction shaft 1 in the settler 2 so that a layer of melt 15 having a top surface 16 is formed in the settler 2.
The method includes also a gas removing step for removing process gases 17 from the suspension smelting furnace via the uptake shaft 4.
The method includes additionally an arranging step for arranging at least one injection means 18 for injecting at least one of fluid 19, such as liquid for example small water droplets and/or gas for example technical oxygen, and pulverous matter 20 for example pulverized coal or coke into the settler 2 from at least one of the first side wall stmcture 8 and the second side wall stmcture 9 of the settler 2, so that at least one of fluid 19 and pulverous matter 20 injected into the settler 2 by means of said at least one injection means 8 will enter the settler 2 above the top surface 16 of the layer of melt 15 in the settler 2.
The method includes additionally an injecting step for injecting at least one of fluid 19 and pulverous matter 20 into the settler 2 by means of said at least one injection means 18.
In a preferred embodiment of the method the injecting step includes injecting at least one of fluid 19 and pulverous matter 20 into the settler 2 by means of at least one injection means 18 a direction parallel or almost or substantially parallel with the top surface 16 of the layer of melt 15. By doing so, mixing of fluid 19 and/or pulverous matter 20 fed by means of said at least one injection means 18 with the layer of melt 15 in the settler 2 can more effectively be avoided, because the risk that a jet containing fluid 19 and/or pulverous matter 20 hits the top surface of the layer of melt 15 is in this embodiment reduced.
In another preferred embodiment of the method the injecting step constitutes of injecting at least one of fluid 19 and pulverous matter 20 into the settler 2 by means of at least one injection means 18 a direction parallel with the top surface 16 of the layer of melt 15.
In a preferred embodiment of the method the arranging step includes arranging injection means 18 at both the first side wall structure 8 of the settler 2 and the second side wall structure 9 of the settler 2. In this preferred embodiment of the method, the arranging step included preferably, but not necessarily, arranging the injection means 18 in the arranging step in an unaligned configuration so that the injection means 18 at the first side wall structure 8 points at the opposite second side wall structure 9 and so that the injection means 18 at the second side wall structure 9 points at the opposite first side wall stmcture 8 as is shown in figure 2. In other words, in this preferred embodiment of the method, the arranging step included preferably, but not necessarily, arranging the injection means 18 in the arranging step so that the injection means 18 are not aligned in such manner that the injection means 18 at the first side wall structure 8 would points at the injection means 18 at the opposite second side wall structure 9 and vice versa. By arranging the injection means 18 in such unaligned configuration, the possibility that fluid 19 and/or pulverous matter 20 injected by means of injection means 18 at the first side wall stmcture 8 will collide in the middle of the settler 2 with fluid 19 and/or pulverous injected by means of injection means 18 from the opposite second side wall stmcture 9 is lower, and this leads to an evener distribution of fluid 19 and/or pulverous matter 20 injected by means of injection means 18 in the settler 2.
In a preferred embodiment of the method the arranging step includes arranging at least one injection means 18 at a region of the settler 2 between the first communication point 3 that is formed between the lower end of the reaction shaft 1 and the settler 2 and the second communication point 5 between the settler 2 and a lower end of the uptake shaft 4.
Next the suspension smelting furnace will be described in greater detail.
The suspension smelting furnace comprises a reaction shaft 1.
The suspension smelting furnace comprises additionally a concentrate burner 12 for feeding non-ferrous metal sulfides 13 such as sulfidic copper concentrate, sulfidic nickel concentrate, sulfidic zinc concentrate or sulfidic matte, for example sulfidic copper matte, sulfidic nickel matte, or sulfidic zinc matte, and reaction gas 14 such as air, oxygen-enriched air or oxygen and possible also flux and/or fine dust into the reaction shaft 1 to have non-ferrous metal sulfides 13 and reaction gas 14 to react together in the reaction shaft 1 to produce melt.
The suspension smelting furnace comprises additionally a settler 2 in communication with the reaction shaft 1 via a first communication point 3 that is formed between a lower end of the reaction shaft 1 and the settler 2, wherein the settler 2 is adapted for receiving melt from the reaction shaft 1 so that a layer of melt 15 having a top surface 16 is formed in the settler 2. The settler 2 comprises a bottom structure 6, a top wall structure 7, a first side wall structure 8 and a second side wall structure 9 between the bottom structure 6 and the top wall structure 7, and a first end wall structure 10 at one end of the settler 2 and a second end structure 11 at the opposite end of the settler 2.
The suspension smelting furnace comprises additionally an uptake shaft 4 for removing process gases 17 from the suspension smelting furnace via the uptake. The uptake shaft 4 in communication with the settler 2 via a second communication point 5 that is formed between the settler 2 and a lower end of the uptake shaft 4.
The suspension smelting furnace comprises additionally at least one injection means 18 for injecting at least one of fluid 19, such as liquid, for example small water droplets, and/or gas, for example technical oxygen, and pulverous matter 20, for example pulverized coal or coke, into the settler 2 from at least one of the first side wall stmcture 8 and the second side wall structure 9 of the settler 2, so that at least one of fluid 19 and pulverous matter 20 is injected by means of said least one injection means 18 into the settler 2 above the top surface 16 of the layer of melt 15 in the settler 2.
In a preferred embodiment of the suspension smelting furnace, said at least one injection means 18 for injecting fluid 19 and/or pulverous matter 20 into the settler 2 is configured for injecting fluid 19 and/or pulverous matter 20 into the settler 2 in a direction parallel or almost or substantially parallel with the top surface 16 of the layer of melt 15.
In a preferred embodiment of the suspension smelting furnace, injection means 18 are arranged at both the first side wall structure 8 of the settler 2 and the second side wall structure 9 of the settler 2. In this preferred embodiment of the suspension smelting furnace, the injection means 18 are preferably, but not necessarily, arranged in an unaligned configuration so that the injection means 18 at the first side wall structure 8 points at the opposite second side wall structure 9 and so that the injection means 18 at the second side wall structure 9 points at the opposite first side wall structure 8 as is shown in figure 2. In other words, in this preferred embodiment of the suspension smelting furnace, the injection means 18 are preferably, but not necessarily, arranged so that the injection means 18 are not aligned in such manner that the injection means 18 at the first side wall structure 8 would point at the injection means 18 at the opposite second side wall structure 9 and vice versa. By arranging the injection means 18 in such unaligned configuration, the possibility that fluid 19 and/or pulverous matter 20 injected by means of injection means 18 from one side wall structure 8 will collide in the middle of the settler 2 with fluid 19 and/or pulverous matter 20 injected by means of injection means 18 from the opposite second side wall structure 9 is lower, which leads to an evener distribution of fluid 19 and/or pulverous injected by means of injection means 18 into the settler 2.
In a preferred embodiment of the suspension smelting furnace at least one injection means 18 is arranged in a region of the settler 2 between the first communication point 3 that is formed between the lower end of the reaction shaft 1 and the settler 2 and the second communication point 5 that is formed between the settler 2 and the lower end of the uptake shaft 4.
It is apparent to a person skilled in the art that as technology advances, the basic idea of the invention can be implemented in various ways. The invention and its embodiments are therefore not restricted to the above examples, but they may vary within the scope of the claims.
