Description
Technical field
The utility model relates to a kind of multiple ligand compound coordination ammonia process and leaches the device that blast furnace dust reclaims zinc, belongs to technical field of wet metallurgy.
Background technology
Outside dezincification Mineral resources, the extremely important available stocks of metallurgical slag Chen Yeshi China such as residues containing zinc dirt, be mainly in blast furnace ironmaking process and produce zinc-containing mash gas mud and gas ash, the zinc smoke that arc melting process produces, the zinc smoke after lead smelting slag volatilization and From Zinc Hydrometallurgy Residue etc.China is the first in the world Iron and Steel Production big country, produces iron and steel more than 500,000,000 tons per year.According to statistics, often produce 1 ton of steel and produce 10 ~ 15kg blast furnace top gas mud containing Zn, every year by-product is gone out gas ash about 500 ~ 7,000,000 tons, containing metal zinc amount more than 500,000 tons; According to International Lead zinc research organization (ILZSG) statistics, 7,500,000 tons, world's electric arc furnace (EAF) cigarette ash in 2007, containing zinc 18 ~ 35%, containing metal zinc amount about 1,500,000 tons.Along with the increase of China's regeneration iron and steel amount, gas mud amount and zinc content will sharply increase; Within 2011, China produces nearly 5,000,000 tons of metallic lead, and containing the slag of zinc about 10% in plumbous smelting process, slag obtains secondary zinc oxide cigarette ash through fuming furnace volatilization, annual 600000 tons, the secondary zinc oxide cigarette ash produced.Zinc hydrometallurgy has occupied more than 80% of world's zinc metallurgy total amount, this process produces a large amount of zinc leaching residues, these material containing zincs are the secondary zinc oxide of the plurality of impurities such as iron content (being up to 14%), calcium (being up to 19%), chlorine (being up to 12%), fluorine (being up to 2%), zinc mainly exists with zinc oxide, franklinite and zinc silicate form, ferro element mainly exists with Z 250 and franklinite form, and calcium constituent mainly exists with the silicate patterns of calcium carbonate and iron content zinc calcium.Therefore, the same with zn Mineral resource, adopt existing acidleach treatment technology and art breading residues containing zinc dirt fluorine cl content high, resource utilization is low.
Current Steel Plant zinc-containing dust treatment process is more, but all there is open question.Wherein rotary kiln evaporation method is containing the most traditional method of Zn scrap returns process.
Patent application 201110444928.5 disclosed " a kind of from containing the method reclaiming valuable metal zinc solid waste " (publication number is CN 102492855 A), its method is by coal, containing Zn scrap returns and gas mud or gas ash mix, burn at rotary kiln high-temperature zone (about 1300 DEG C), zinc is made to form metallic zinc steam, under the condition of air blast, oxygen generation oxidizing reaction in metallic vapor and air obtains metal zinc oxide, oxide powder and zinc is become, to reach the object being rich in valuable metal through air cooling pipe and pulsating collection.
Patent application 201210369145.X disclosed " utilizing rotary kiln to reclaim method and the device thereof of zinc " (publication number is CN 102899505 A), blast-furnace dust, electric furnace ash, gas mud and hard coal is adopted to carry out mix in its method, at 800 DEG C ~ 1050 DEG C, high-temp combustion makes zinc gasify, settling pocket and flue dust dust separation is entered at centrifugal blower effect gasified zinc, and do cooling process by surface cooler, gasify zinc and oxygen contact preparation zinc oxide in the process.
Patent application 201410330341.5 disclosed " iron content zinc powder dirt recycles technique " (publication number is CN 104073649 A), its method: mixed with coal dust and binding agent by dried iron content zinc powder dirt, pelletizer pelletizing, obtains green-ball; Green-ball is sent into shaft furnace, is warming up to 1100 ~ 1300 DEG C, the zinc be reduced at high temperature becomes zinc fume and discharges shaft furnace with coal gas, enters two-step filter; Fly-ash separator gained dedusting mud enters sedimentation tank filter, precipitation, multiviscosisty, drying obtain zinc powder.
Above-mentioned traditional treatment method all belongs to pyrogenic attack and reclaims zinc, its enter furnace charge calorific value all require high, domestic current most of enterprise enter furnace charge calorific value 2000 kilocalories/kilogram more than, operating rate is low, short, the comprehensive power consumption of life-span of kiln liner is high, treatment capacity is little, investment is large, coke consumption rate is large, and tailings is high containing energy consumptions such as zinc, charcoal are high, particularly to poor feasibility economically during treatment and use low-grade material.In addition, adopt long rotary kiln process mixing pelletizing or dust, then need employing two sections of rotary kilns to the zinc directly reclaimed in dust, enter second rotary kiln containing zinc fume and carry out reprocessing, equipment is huge, and efficiency is low, easily produces ring formation phenomenon.
Therefore, how difficult Mineral resources of cost-effective efficiency utilization and select smelting waste are urgent problems instantly.
Summary of the invention
For above-mentioned prior art Problems existing and deficiency, the utility model provides a kind of multiple ligand compound coordination ammonia process to leach the device of blast furnace dust recovery zinc.Leaching device of the present utility model is simple to operation, the advantages such as zinc leaching rate is high, economic environmental protection, and the utility model is achieved through the following technical solutions.
A kind of multiple ligand compound coordination ammonia process leaches the device that blast furnace dust reclaims zinc, this device comprises airtight Leaching reaction device and condensation-purification-reflux, described airtight Leaching reaction device comprises groove thorax 1, vapor communication pipeline 2, leaching vat 3, charging opening 4, digital display temperature measurer 5, agitator 6, electric blender 7 and stirring digital display controller 8, condensation-purification-reflux comprises stirring digital display controller 8, condensing reflux pipe 9, surge flask and scrubbing bottle, groove thorax 1 is built-in with leaching vat 3, leaching vat 3 top is provided with the digital display temperature measurer 5 and agitator 6 that insert leach liquor, agitator 6 connects electric blender 7 successively, stir digital display controller 8, leaching vat 3 top successively with condensing reflux pipe 9, surge flask, scrubbing bottle connects, leaching vat 3 periphery is covered with vapor communication pipeline 2, leaching vat 3 are provided with charging opening 4.
