Abstract
The utility model discloses a circular smelting furnace, which comprises a circular furnace body, the furnace roof is provided with a charging port, a furnace door and at least five burners are arranged along the circumferential direction on the middle upper part of the furnace wall, wherein the furnace door and the burners are located on the same horizontal plane; a horizontal flue is arranged on the furnace wall, and the vertical height of the horizontal flue is not less than the vertical height of the burners; the middle lower part of the furnace wall is provided with a slag taphole, and the furnace wall is provided with a lead taphole close to the bottom of the furnace body. The circular smelting furnace has the advantages that: because the circular furnace body does not have dead corners, the utilization rate of the furnace chamber is high, and slag can be easily cleaned off; fuel which is injected from the specific burners is concentrated in the center of the furnace body, so material can be sufficiently and uniformly burnt; the smoke produced in the process of burning can be exhausted from the flue in time; because material enters the furnace body from the roof of the furnace body, not only can the rising high-temperature smoke waste heat in the furnace body be sufficiently utilized, but also the smoke temperature can be decreased, which is more favorable for the exhaust of smoke.
Description
Technical field
The utility model belongs to non-ferrous metal smelting furnace, is specifically related to the smelting furnace of pre-desulfurization lead-containing material in lead accumulator recovery.
Background technology
At present, in Production of Secondary Lead melting operation, mostly adopt rotary kiln and direct coal-fired reverberatory furnace.Rotary kiln is non-static melting, has the defects such as the leaded height of waste, dust rate height; And direct coal-fired reverberatory furnace energy consumption is high, environmental pollution is large, country has prohibited use.Meanwhile, existing smelting furnace mostly is square furnace, has dead angle, and raw material or waste residue are easily assembled, and it cannot be made full use of or clean out.
Utility model content
Utility model object: the purpose of this utility model is to provide that a kind of thermal efficiency is high, dust rate is low, vertical yield is high and the leaded low circular melting furnace of waste.
Technical scheme: circular melting furnace described in the utility model, comprise circular body of heater, furnace roof is provided with charge door, and middle and upper part, furnace wall is along being circumferentially with fire door and at least five burners, and wherein, fire door and burner are positioned in same level; On this furnace wall, establish horizontal flue, the vertical height of horizontal flue is not less than the vertical height of burner; Middle and lower part, furnace wall is provided with slag notch, and the furnace wall that approaches bottom of furnace body position is provided with lead outlet.
Wherein, described furnace roof adopts magnesium chromium matter casting material and the cast molding of high-temperature fibre silk.
Described furnace wall is provided with outer cover of steel plate, aluminosilicate fiberboard, insulating brick and magnesite-chrome brick from outside to inside successively.
Described furnace bottom is built and is had insulating brick masonry and high alumina ramming mass successively from bottom to top.
Described burner is distributed on furnace wall.
Beneficial effect: compared with prior art, its advantage is the utility model: 1, circular body of heater, without dead angle, burner hearth utilization rate is high, waste residue easy to clean; 2, the number of burner and position make the fuel spraying into concentrate on body of heater center, make material obtain fully and uniformly burning; 3, the flue gas producing in combustion process can be discharged from flue in time; 4, material enters in stove from body of heater top, both can make full use of the high-temperature flue gas waste heat rising in body of heater, can reduce flue-gas temperature again, is more conducive to flue gas and discharges.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, this smelting furnace is circular, and without dead angle, raw material availability is high, waste residue easy to clean.Stove comprises circular body of heater 1, and furnace roof is convex bell, and furnace roof adopts magnesium chromium matter casting material and the cast molding of high-temperature fibre silk, at furnace roof, is provided with charge door 2.Furnace wall is provided with outer cover of steel plate 8, aluminosilicate fiberboard 9, insulating brick 10 and magnesite-chrome brick 11 from outside to inside successively, and wherein aluminosilicate fiberboard, insulating brick and magnesite-chrome brick form brick setting furnace wall.Edge, middle and upper part, furnace wall is circumferentially with fire door 3, and evenly offers the burner 4 (or over five) of five groove shapes, and wherein, fire door 3 and burner 4 are positioned in same level.On this furnace wall, establish horizontal flue 5, the vertical height of horizontal flue is not less than the vertical height of burner simultaneously, and the flue gas that can make burning produce is discharged in time.Middle and lower part, furnace wall is provided with slag notch 6, and the furnace wall that approaches bottom of furnace body position is provided with lead outlet 7.Described furnace bottom is built and is had insulating brick masonry 12 and high alumina ramming mass 13 successively from bottom to top.
The course of work: lead-containing material is through fragmentation-sorting-pre-desulfurization, from charge door, enter in stove, five burners spray into fuel (natural gas or coal gas) and combustion-supporting pure oxygen burns, the interior material of stove is melted and guarantee continuous high temperature in stove, because burner is distributed on each orientation, furnace wall, the fuel spraying into is center concentrated combustion in stove, and in stove, temperature is even, the abundant melting of material, without hot-spot burn-off phenomenon.After melting finishes, slag is emitted from slag notch, and lead is emitted from lead outlet, and inner flue gas of the stove is discharged from horizontal flue.
