Description
Technical field
The present invention is the smelting equipment that is applied to process bismuth concentrate, lead ore concentrate or plumbous bismuth collective concentrate, particularly a kind of oxygen-rich oxide reduction furnace.
Background technology
Be all to adopt reverberatory furnace, blast furnace and converter at present in refining bismuth field, aforesaid device exists energy consumption high, and supplementary product onsumption is large, and cost is high, flue gas can't relieving haperacidity etc. problem.And the melting technology of lead ore concentrate has oxygen-enriched bottom-blowing, oxygen-enriched top blowing, QLS oxygen bottom blown furnace refining lead etc. to replace traditional sintering-Lead Smelting in Blast Furnace technique.QLS oxygen bottom blown furnace lead smelting process is that lead-containing material is directly put in the round tube type stove, and the industrial oxygen oxidizing semlting by 90% obtains high lead slag, and high lead slag flow in reduction furnace by the hole of furnace bottom again, and the flue gas of the high density that produces is used for relieving haperacidity.The structure of QLS oxygen bottom blown furnace is the cylinder stove of a waney integral body, in the inside of body of heater, partition wall is set one, cylindrical shell is divided into independently two portions, the part that diameter is large is used for the oxidation of raw material, be oxidation panel, oxygenant adopts 90% industrial oxygen, send in stove by bottom of furnace body oxygen rifle, so this part also is the oxygen bottom blowing oxidized still; The part that diameter is little is used for the reduction of the melting high lead slag of oxidation panel output, and reductive agent adopts fine coal (or Sweet natural gas), send in reduction furnace by the composite spray gun of bottom of furnace body, and reduction output lead bullion and slag, so this part is reduction section or reduction furnace.Because the QLS oxygen bottom blown furnace is an integral body, there are three problems or defective aspect device fabrication, transportation, installation, operation:
1, oxidation panel body of heater and reduction section body of heater are integrated to make and install, and it is large that equipment always reaches the 30m-35m volume, and more than 500 tons of weight of equipment are large.The manufacturing of equipment, transportation, installation difficulty are large, and the apparatus processing manufacturing expense is high;
2, the whole stove of the oxidized still section of traditional QLS oxygen bottom blown furnace and reduction furnace Duan Weiyi, share the set of gears electro-mechanical driving device, wherein primary reformer goes wrong or when changing parts, two sections stoves all must stop producing, and can produce furnace accretion, need whole equipment parking maintenance to process;
3, the fire-resisting partition between oxidation panel and reduction section is in regular damage under the impact of the high corrosion of high temperature slag for a long time, is difficult for maintenance, causes industrial accident to shut down.
Summary of the invention
Problem based on above-mentioned existence, the present invention proposes a kind of oxygen-rich oxide reduction furnace, device fabrication, transportation, installation, inconvenient problem or the defective of operation aspect existence both can have been solved, the heat energy that can utilize again oxidizing reaction to produce, lower energy consumption and supplementary product onsumption, also have simultaneously the flue gas acid preparing of the high density utilized, process the advantages such as furnace accretion convenience.
Technical scheme of the present invention is: a kind of oxygen-rich oxide reduction furnace is divided into oxidation body of heater and reduction body of heater two parts; It is characterized in that: be provided with independently furnace foundation, cupola well, tuyere, siphon port, opening for feed, discharge port and floss hole on two bodies of heater; In two bodies of heater, the lowest part of cupola well also is equipped with safe mouthful; The furnace foundation fundamental plane installation position of oxidation oven body part will be higher than the furnace foundation fundamental plane of reduction oven body part, and the discharge port of oxidation oven body part has chute to be connected between the opening for feed of body of heater with reducing; Outer side at oxidation oven body part cupola well is provided with the dry slag mouth.
The cupola well of described two bodies of heater all adopts magnesite chrome brick to build into low early and high after ladder pond shape by laying bricks or stones, and water jacket is copper film chamber shape water jacket.
Compared with the prior art, the present invention adopts and is divided into oxidation body of heater and reduction body of heater two parts, by the oxidation body of heater being set with the reduction body of heater and using the chute syndeton, be used for metal sulfide in oxidized still after oxidation melt enter the reduction furnace reduction by chute and obtain the melting equipment of metal, reduced individual equipment length, be beneficial to processing and manufacturing, transportation, installation, the operation of equipment, facilitate the maintenance of equipment, reduce repair time and and equipment making and running cost.The present invention regulates carbon-to-oxygen ratio by the carbon add-on of adjusting opening for feed and the oxygen add-on of tuyere, thereby redox condition in the control stove, realize that the nonferrous metal sulfide minerals such as plumbous bismuth are oxidized to metal oxide in oxidized still, directly enter by the intermediate chute intermediate chute a kind of metallurgical equipment that reduction furnace is reduced into metal again, because used oxygen-rich air, reduced exhausted air quantity, improved sulfur dioxide concentration, realized acid exhaust, therefore has environment good, energy consumption is low, and labour intensity hangs down the high advantage of operating efficiency.Oxidized still of the present invention is provided with the dry slag mouth in case furnace accretion, and when the lowest part of body of heater cupola well is provided with safety and mouthful is used for blowing out, emptying body of heater material is so that maintenance.Cupola well of the present invention adopts magnesite chrome brick to build by laying bricks or stones, low early and high after design so that metal liquid collect.Water jacket adopts copper water jacket, tuyere to be provided with tuyere and secondary tuyere, makes reaction more abundant, the oxidized still furnace foundation higher than the reduction furnace furnace foundation so that the melt gravity flow.
