Description
Technical field
The present invention relates to that a kind of stibium blast furnace produces the antimony sulfonium, needle antimony is waved the device of blown converter and is applied to direct converting method.
Background technology
At present, the antimony production technique adopts pyrometallurgical smelting process more than 90% both at home and abroad, and pyrometallurgical smelting process is again with antimony concentrate blast furnace volatile smelting---and the technical process of antimony reverberatory furnace retailoring purified is main.Stibium blast furnace is high with its siege processing power, and strong to adaptability to raw material, characteristics such as metal recovery rate height receive the generally favor of antimony smelting enterprise.The stibium blast furnace major product is an Antimony Trioxide: 99.5Min, and by-product is antimony sulfonium, needle antimony, but existing stibium blast furnace produces antimony sulfonium, needle antimony output capacity high (about 20～30%), and foreign matter content high (about 15～30%) needs further to handle.At present, stibium blast furnace produces the antimony sulfonium, needle antimony is after emitting from the stibium blast furnace external crucible, and warp cooling, fragmentation get into stibium blast furnace or wave blown converter and handle, recovery antimony valuable metal and noble metal wherein.The science and engineering skill does not only make full use of the heat energy of hot melt attitude antimony sulfonium, needle antimony here, and needs to consume antimony sulfonium, the needle antimony refuse smelting that a large amount of energy consumptions makes cold conditions, and bituminous coal unit consumption 980kg/t goes into the stove material.Simultaneously, get into stibium blast furnace as the article that return, influence a series of technico-economical comparisones such as processed in units amount of stibium blast furnace, thereby the stibium blast furnace production cost is raise as if cold conditions antimony sulfonium, needle antimony.
CN200810031214.X discloses a kind of stibium blast furnace melting method that adopts oxygen-rich air; Be oxygen that air-separating oxygen-making equipment or vaporization of liquid oxygen device are produced through pipe-line transportation in the airduct of gas blower front end or rear end; Be mixed into the oxygen-rich air of oxygen-containing gas volume concentrations >=22% with air by preset proportion, introduce blast furnace through the air port.The present invention be fit to handle the various antimong-containing materials such as returning charge that contain the antimony oxide ore of antimony more than 15%, antimony sulfide ore, sulphur and oxygen mixed antimony ore, jamesonite, antimony smelting process; Also be fit to processing bulk or powdery antimony material through the various different profiles of balling-up processing.Bed processing power of the present invention improves>=50%, and burnt rate reduces>=40%, and the iron ore rate reduces>=40%, and the antimony comprehensive recovery reaches>=and 97%, the SO in the waste gas
2Concentration improves 50%～100%, for next step waste-gas desulfurization (or relieving haperacidity) is handled, qualified discharge provides better condition.Present method blowing raw material is the product that this patent is produced.
CN200310104235.7 utilizes fuming furnace to handle the lead stibium blast furnace waste residue for one kind, comprehensively reclaims the technology of the fuming comprehensive treating process lead stibium blast furnace slag of valuable metals such as zinc in the waste residue, antimony, lead, indium.Be characterized in that the lead stibium blast furnace waste residue is put into fuming furnace and accomplish melting---blowing---volatilization process, can in a single Reaktionsofen, accomplish the heterogeneous reaction and the space gas-solid/liquid/gas reactions of solid, liquid, gas.The fuming process reaction comprises the burning of carbon and the gasification reaction of carbon, the fusing of cold burden and the reduction of MOX and oxidizing reaction, and the gas that reduction volatilization is come out gets into flue gas simultaneously and after the water cooler cooling, gets into the bag collection recovery.Thereby the advantage that has of the present invention is that metal recovery rate is high, and treatment capacity is big, and mechanization degree is high and energy consumption is low.What this patent was handled is that stibium blast furnace produces waste residue, and present method is only handled antimony sulfonium, needle antimony, and slag separates at the stibium blast furnace external crucible.
Summary of the invention
The objective of the invention is to overcome the defective that prior art exists, provide a kind of stibium blast furnace product antimony sulfonium, needle antimony to wave the device of blown converter and be applied to the directly method of blowing.To realize that getting into antimony sulfonium, the needle antimony of waving Bessemer blow is hot melts, does not need indirect heating can realize continuous production; And can improve stibium blast furnace siege processing power.
Technical scheme of the present invention is:
A kind of stibium blast furnace produces antimony sulfonium, needle antimony and waves the blown converter device that directly blows, and comprises stibium blast furnace, is located at the stibium blast furnace external crucible of external crucible burner top, waves blown converter; It is characterized in that, between stibium blast furnace and stibium blast furnace external crucible, be provided with the slag road, saidly wave the afterbody that blown converter is located at stibium blast furnace stokehold bed, be provided with the antimony road waving between blown converter and the stibium blast furnace stokehold bed.
Stibium blast furnace produces the antimony sulfonium, needle antimony is waved the directly method of blowing of blown converter: may further comprise the steps:
(1) antimong-containing material is after stibium blast furnace voloxidation melting, and most of antimony gets into the condensation dust collecting system with the volatilization of Antimony Trioxide: 99.5Min gaseous state; Few part antimony gets into the slag phase with antimony sulfonium, needle antimony form, gets into the stibium blast furnace external crucible mutually together with the fused slag;
(2) needle antimony in (1) step is got into the stibium blast furnace external crucible through the slag road; Difference according to antimony sulfonium, needle antimony proportion and slag proportion; Slag floats on antimony sulfonium, the needle antimony; Realize that antimony sulfonium, needle antimony separate with slag; (proportion of antimony sulfonium, needle antimony is 6.5 * 10
3Kg/m
3, the proportion of slag is 3.0 * 10
3Kg/m
3)
(3) antimony sulfonium, needle antimony directly get into through the antimony road and wave blown converter; External crucible with wave the blown converter melt liquid level and reach balance after, the external crucible melt no longer gets into waves blown converter; Slag is isolated through slag notch;
When (4) waving Bessemer blow, wave the blown converter melt liquid level and descend, antimony sulfonium, needle antimony that stibium blast furnace is produced constantly replenish to get into after the external crucible sedimentation waves blown converter, realizes waving the blown converter continuous production.
The present invention with stibium blast furnace, stibium blast furnace external crucible, wave blown converter and distribute rationally, antimony sulfonium, needle antimony are directly got into through the antimony road wave blown converter; Made full use of the heat energy of stibium blast furnace stokehold bed, making and getting into antimony sulfonium, the needle antimony of waving Bessemer blow is hot melts, does not need indirect heating can realize continuous production; Optimized the technico-economical comparison of stibium blast furnace, stibium blast furnace siege processing power improves >=10%, and burnt rate reduces >=5%, and the antimony comprehensive recovery improves >=0.2%; The noble metal comprehensive recovery improves >=3.0%.
