Abstract
The utility model discloses a kind of gooseneck structure of Antimony Making Blast Furnace, the gooseneck structure of Antimony Making Blast Furnace is exactly the circular bridge piece of blast furnace and dust chamber, adopt " people " font water-cooled flue to connect, the manufactured size of gooseneck be directly connected to stove ore deposit normally whether.The utility model is 47 ° to 49 ° by gooseneck angle [alpha], slant range is increased to and is more than or equal to 1.5 meters, effectively raises the degree of oxidation of antimony, has reduced greatly employee and clear up the labour intensity of gooseneck, has increased smelting time, has improved economic benefit.
Description
Technical field
The utility model relates to a kind of Antimony Making Blast Furnace, particularly relates to a kind of gooseneck structure of Antimony Making Blast Furnace.
Background technology
After nineteen sixty, antimony ore blast-furnace method becomes the important method of producing metallic antimony.Multiple volatile smelting and volatilization roasting method are developed 60～seventies.In antimony concentrate blast furnace volatile smelting process, there is oxidizing reaction in flue gas in blast furnace, enters gooseneck generation secondary oxidation, and gooseneck is the reaction chamber of oxidizing reaction and the effect of playing cooled flue gas.The gooseneck structure of Antimony Making Blast Furnace is exactly the circular bridge piece of blast furnace and dust chamber, adopts " people " font water-cooled flue to connect, the manufactured size of gooseneck be directly connected to stove ore deposit normally whether.The gooseneck structure of Antimony Making Blast Furnace is at present: gooseneck angle [alpha] is 42 °, gooseneck slant range L is 1.0 meters of left and right, at present domestic in the very large problem of cleaning gooseneck existence, long in the antimony concentrate blast furnace smelting cleaning gooseneck structure time, affect the normal production time of blast furnace.The cooling gooseneck of stibium blast furnace melting industry, reduces the temperature of flue gas by the way that adds water(-cooling) jacket.Antimong-containing material is melting volatilization oxidation in blast furnace, enters flue and gooseneck and carries out secondary oxidation reaction, through the flue-gas temperature 900-1000 DEG C of the cabinet that overdoes, cools to temperature out below 800 DEG C by gooseneck.In gooseneck, there is reduction reaction and produce needle antimony in antimony, antimony generation oxidizing reaction produces antimony oxygen deposition at gooseneck, antimony sulfide fail complete oxidation produce red water, the powder of coke, iron ore, Wingdale, antimony concentrate is deposited in gooseneck through exhausting, be deposited on for above-mentioned reasons the material in gooseneck, hardness is large, temperature is high, dust is large, increases worker's labour intensity.
In order to overcome the shortcomings of existing air blast gooseneck scarfing cinder, the utility model lengthens blast furnace gooseneck, and angle increases, and develops the process system adapting with it, realistic meaning highly significant.
Utility model content
Technical problem to be solved in the utility model is to provide one can extend the required high-temperature time of gooseneck secondary oxidation, can reduce again the gooseneck structure of the Antimony Making Blast Furnace of labour intensity.
In order to solve the problems of the technologies described above, the gooseneck structure of the Antimony Making Blast Furnace that the utility model provides, comprises gooseneck body, and the gooseneck angle [alpha] of described gooseneck body is 47 ° to 49 °.
The gooseneck slant range L of described gooseneck body is more than or equal to 1.5 meters.
The gooseneck angle [alpha] of described gooseneck body is 48 °.
The gooseneck slant range L of described gooseneck body is 2.126 meters.
The gooseneck structure of Antimony Making Blast Furnace that adopts technique scheme, original size remains unchanged, and increases gooseneck angle to 47 ° to 49 °, has reduced gooseneck bridging, has significantly reduced cleaning gooseneck labour intensity; Addition gooseneck slant range to being more than or equal to 1.5 meters, extended the fume high-temperature time, effectively raise the secondary oxidation efficiency of antimony, weisspiessglanz quality is optimized, and has improved economic benefit.
Compared with prior art, the beneficial effects of the utility model are:
1, stibium blast furnace volatile smelting Technology Need carries out secondary oxidation at gooseneck, extends gooseneck size, can effectively increase flue-gas temperature, make that antimony secondary oxidation carries out completely.
2, save the production time, compare with former gooseneck, the cleaning gooseneck time needs 1～2 hour at every turn, every day a clear gooseneck, after improving angle, gooseneck does not need cleaning substantially, within 1 year, just can save 300～600 hours/year production times;
3, in gooseneck, material hardens, and material is containing antimony quality weight, and operation easier is large, is difficult for clawing, and existing gooseneck angle increases, and does not substantially clear up, and reduces labour intensity.
In sum, the utility model is that one can extend the required high-temperature time of gooseneck secondary oxidation, can reduce again the gooseneck structure of the Antimony Making Blast Furnace of labour intensity, has reached the dual purpose that improves secondary oxidation effect and save the valuable production time.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Following embodiment is intended to illustrate the utility model instead of to further restriction of the present utility model.The utility model can be implemented in the described any mode of utility model content.
Referring to Fig. 1, the gooseneck structure of Antimony Making Blast Furnace, original size remains unchanged, and the gooseneck angle [alpha] of gooseneck body 1 is 47 ° to 49 °, and preferably, the gooseneck angle [alpha] of gooseneck body 1 is 48 °.
Further, the gooseneck slant range L of gooseneck body 1 is more than or equal to 1.5 meters, and preferably, the gooseneck slant range L of gooseneck body 1 is 2.126 meters.
Referring to Fig. 1, the gooseneck structure of the Antimony Making Blast Furnace of stibium blast furnace melting industry, reduces the temperature of flue gas by the way that adds water(-cooling) jacket.Antimong-containing material is melting volatilization oxidation in blast furnace, enters gooseneck body 1 and carries out secondary oxidation reaction, and through 900～1000 DEG C of the flue-gas temperatures of the cabinet that overdoes, the secondary oxidation of antimony need carry out above at 800 DEG C.
Referring to Fig. 1, the gooseneck structure of Antimony Making Blast Furnace, original size remains unchanged, and increases gooseneck angle to 47 ° to 49 °, has reduced gooseneck bridging, has significantly reduced cleaning gooseneck labour intensity; Addition gooseneck slant range to being more than or equal to 1.5 meters, extended the fume high-temperature time, effectively raise the secondary oxidation efficiency of antimony, weisspiessglanz quality is optimized, and has improved economic benefit.
