Background technology
At present, the development of the electrolytic aluminium yield in China and the world is swift and violent.According to statistics, in by the end of December, 2016, China's electrolytic aluminium
Aluminium smelter enterprise be completed production capacity up to 4369.8 ten thousand tons, run production capacity up to 3673.9 ten thousand tons.With the increasing of electrolytic aluminium yield
Add, caused solid waste in electrolytic process, such as waste cathode carbon block, scrap anode carbon granule, useless refractory brick, useless insulating brick, useless guarantor
The yield of warm clinker also increases sharply, wherein only the caused negative electrode that gives up is up to 250,000 tons every year for China's aluminum electrolysis industry, in recent years still
The accumulative volume of cargo in storage for having more than 400 ten thousand tons fills without suitable area, and the waste cathode carbon block actual amount of whole world stockpiling is up to ten million
Ton.
Aluminium cell carbonaceous waste material includes caused waste cathode carbon block and scrap anode carbon granule during electrolytic aluminium etc., predominantly
Waste cathode carbon block.The main component of waste cathode of aluminum electrolytic cell carbon block is C, also contains Na3AlF6、CaF2、NaF、AlF3、α-Al2O3
Deng, wherein carbon content be 50~70%, electrolyte fluoride be 30~50%, cyanide is about 0.2%.Do not have in aluminium electrolysis process
Participate in the anode carbon granule of electrolyte in electrolysis and Electolyte-absorptive(Also known as anode breeze)Main component be with Na3AlF6Based on
Sodium aluminium fluoride, α-Al2O3And C, remaining is electrolyte fluoride, wherein, carbon content is 40~60%.
Electrolytic aluminium waste cathode carbon block belongs to the high artificial material of degree of graphitization, it is well known that electrolytic aluminium negative electrode is to forge
The anthracite of burning, metallurgical coke, graphite etc. are that aggregate, coal tar pitch etc. is made up of binding agent shaping and roasting, for charcoal containing aluminium cell
The block class or paste class carbon product of matter liner, are graphitization or graphite carbon cellulosic material, with hardness is big, coefficient of friction is small, no
Broken, extremely difficult combustion(Relative to fire coal)The characteristics of.The electrolysis temperature of modern large-scale aluminium electrolysis pre-baking tank 950~970 DEG C it
Between, the electrolyte such as 1 ton of aluminium consumption about 50kg ice crystals, aluminum fluoride, magnesium fluoride are often produced, due to heat effect, chemical action, machinery
Erosion effect, electro ultrafiltration, sodium and electrolyte infiltration etc. caused by fused salt reaction, chemical reaction, the negative electrode charcoal in aluminium cell
Block can be damaged after using certain time, needs to carry out large repairs after typically running 4~7 years, the mainly waste cathode carbon block that removes,
Waste refractory materials, useless insulation material etc., while a certain amount of anode carbon granule is also produced in electrolytic process.
For the treatment technology of the less scrap anode carbon granule of quantity, current research is concentrated mainly on is returned using floatation process
Charcoal and electrolyte are received, by scrap anode carbon granule grinding to certain particle size, adds water to add collecting agent after sizing mixing, makes charcoal abundant with electrolyte
Separation, so as to obtain using electrolyte as two kinds of products advocating peace based on charcoal.Electrolyte therein can back within aluminium electroloysis
In groove, powdered carbon can be used for the raw material that Soderberg Anode In Aluminium Electrolysis Cells make anode mix, but processing cost is high and secondary pollution is big.
For waste cathode of aluminum electrolytic cell carbon block, at present both at home and abroad the technical method of processing waste cathode carbon block up to tens of kinds it
It is more, it may be summarized to be wet method, high temperature hydro-thermal method, superhigh temperature partition method, burning partition method, fuel process and security landfill method etc..
(1)Wet method:For the main direction of studying of current internal lining of aluminium electrolytic bath, basic working procedure is grinding, water logging/alkali leaching/acid
Wash, flotation, separation, drying etc..The external representative use aquation method released for M.M.Williams handles waste cathode carbon
Block(Isolated thick carbon granule and fine grain electrolyte), and Austrian Lun Sihuofen aluminium manufacturers and Li Sita aluminium manufacturers of U.S. alkali
The molten leaching electrolyte therein of liquid(Leachate is used for synthetic cryolite, and charcoal is used as the fuel of high temperature furnace collocation).Chalco stock
Part Co., Ltd, Beijing Mine and Metallurgy General Inst, Central South University etc. have also carried out substantial amounts of research and practice, as Lu Huimin et al. is used
Floatation reclaims charcoal and electrolyte, and waste cathode carbon block is crushed, obtains the powder of certain particle size after classification, adds water to be added after sizing mixing
Collecting agent, to realize farthest separating for carbon and electrolyte, so as to obtain using electrolyte as advocate peace based on charcoal two kinds
Product.Electrolyte therein can be backed within aluminium cell, and graphited powdered carbon can return to negative electrode production system.But
It is that the toner value that method for wet separation obtains at present is not high, and resource utilization efficiency is low, and the processing power consumption such as grinding is high, place
It is high to manage cost, and serious secondary pollution be present.
(2)High temperature hydro-thermal method separation method:It is most representational to be used for J.E.Dentschman and J.S.Lobos etc.

Middle HF gases generate aluminum fluoride, make fluorine obtain solidifying to re-use, final products are glassy state slag, and the charcoal of recovery is used again
In manufacture cathode material.The technique has carried out commercial Application, handles waste lining year up to 12000t, but invests big, processing energy consumption
Height, processing cost are too high.It is domestic also to have research more, as CN105642649A discloses a kind of high-temperature treatment of electrolytic aluminium waste cathode
Method, it is that electrolytic aluminium waste cathode carbon block is crushed to 3~15mm, then, is roasted in 2600~2800 DEG C of superhigh temperature vacuum electric furnaces
Burning processing, it be nitride to volatilize fluoride therein, decompose cyanide therein, and high-temperature flue gas is by the way of water smoke absorbs
Absorb again by the processing such as filtering drying, obtain can reuse fluoride, the negative electrode carbon materials after superhigh temperature roasting is through being cooled to
Reach 97% carbon materials for fixed carbon content.But this method is significantly present of following problem:First, electrolytic aluminium waste cathode carbon is broken
Toxic dust and toxic gas containing cyanide are produced in broken screening process;Second, it is actual to 2600~2800 DEG C for electrical heating
Power consumption is very high, maintain vacuum suction power consumption it is higher, the requirement of equipment and cost are also very high;Third, 2600~2800 DEG C volatilization
It is too high that fluoride gas using water smoke absorb requirement to equipment, because 1200 DEG C of water vapour can be so that calcirm-fluoride etc. to be fluorinated
Thing is converted into the hydrogen fluoride of the severe corrosive of severe toxicity;Fourth, serious secondary pollution is also easy to produce, and the carbon materials reclaimed
In still contain 3% or more fluoride, recycling can shorten overhaul life and uneconomical.CN106269787A discloses one kind
For disposing the high temperature continous way processing method of electrolytic aluminium waste cathode, teach one kind and be crushed to electrolytic aluminium waste cathode carbon block not
Particle more than 3mm, 3~100mm compound particles are made with kneadings such as pitches, then, compound particles are placed in superelevation
In warm vacuum electric furnace, in not less than 2000 DEG C(2300~2600 DEG C)Continous way calcination process in superhigh temperature vacuum electric furnace, is obtained high
Warm electro-forge flue gas and electrolytic aluminium waste cathode carbon granules, then high temperature electro-forge flue gas is subjected to second-time burning, completely burned volatile matter flue gas
In carbon dust, carbon powder and ice crystal, it is nitride to decompose cyanide therein, after cooling, dedusting, desulphurization denitration, obtains reuse
Fluoride and fixed carbon content reach 95% carbon materials.But this method is significantly present of following problem:First, electrolytic aluminium waste is cloudy
Toxic dust and toxic gas containing cyanide are produced during the carbon crushing and screening of pole;Second, electrical heating to 2000~2600 DEG C its
Actual power consumption is very high, maintains that the power consumption of vacuum suction is higher, and the requirement of equipment and cost are also very high;Third, after second-time burning
Gas cleaning investment is high, is also easy to produce serious secondary pollution;Fourth, still contain in the carbon of 2000~2600 DEG C of electric furnace calcination processing
Substantial amounts of fluoride, because more than 2497 DEG C of the boils up till of calcirm-fluoride, fluorine-containing carbon materials, which recycles, can shorten overhaul time
Limit and it is uneconomical.
(3)Burn separation method:It is to use professional incinerator and fluid bed furnace technique etc., because electrolytic aluminium waste cathode carbon is different
In fire coal, though calorific value is generally up to 4000~5500kcal/kg, activation energy needed for oxidation reaction is high, need to reach 1500 DEG C of height
It is warm could the efficient oxidation burning, therefore combustion method is present that separating process is cumbersome, the heat time needed for after-flame is long, energy consumption is big and difficult
The problem of effectively to reclaim wherein fluoride, and secondary pollution issue handling difficulty is also big.
(4)Fuel process:Because the main component of electrolytic aluminium waste cathode carbon block is charcoal, and the theoretical combustion heat of completely burned is typically up to
More than 4000kcal/kg, high reaches 5500kcal/kg equivalent to conventional anthracitic calorific value, so, domestic and international substantial amounts of skill
Art worker has carried out unremitting effort, and effect pole is not so good as people's will so far.The domestic method as fuel has China YouSe metal
The identification for the Shandong Aluminum Co., Ltd. factory " recycling of waste cathode of aluminum electrolytic cell carbon block " that Industry Corporation organized on November 16th, 1988
Achievement.Specific method is:" Shandong Aluminum Plant in alumina producing, using waste and old cathode carbon block it is levigate after as desulfurizing agent and substitute
Part anthracite is added in alumina rotary kiln, produces alumina sintering block.Contained fluoride salt changes into sinter leaching
Insoluble calcirm-fluoride enters red mud, and red mud replaces fluorescent mineralizer for manufacture of cement dispensing when preparing cement." still,
This method grinding energy is high, the discharge capacity increase of pernicious gas in flue gas.Further to solve the turning sludge into fuel profit of waste cathode carbon block
With problem, research institute of Shandong branch company of Chinese Aluminium Co., Ltd poplar meeting guest waits the cement producing line in Shandong Aluminum Plant enterprising
In-depth study practice is gone, with calorific value 21MJ/kg(5024kcal/kg)Waste cathode carbon block be applied to cement producing line work
Industry is tested, and is specifically first crushed waste cathode carbon block, by the maximum ratio dosage of clinker 5kg waste cathode carbon blocks per ton(Convert and be
About less than the 3% of coal consumption), together grinding is incorporated in coal mill in grinding coal dust, and conclusion (of pressure testing) is clinker per ton by the useless the moon of 5kg
Pole carbon block is to clinker quality without visible influences(Application study light metal of the waste cathode carbon blocks such as Yang Huibin in manufacture of cement,
2nd phase in 2008, P59-64.).Yang Huibin etc. is high using cement kiln internal reaction temperature, carbon block residence time on stream
The condition such as long, makes the harmful substance in waste cathode carbon block carry out decomposition displacement in hot environment, and it is ripe to be finally solidificated in cement
In material, while attempt to reducing the consumption of coal by the use of the carbon in waste cathode carbon block as fuel.But its still have safety problem,
Addition problem and the influence problem to production, after all, waste cathode carbon are not coal-fired, the extremely difficult combustions of charcoal in waste cathode carbon block.So
And the defects of real is not the problem of fluorine is exceeded in the erosion of refractory material caused by fluoride and flue gas, because calcium aluminum fluoride
The production of cement also ensure that refractory material safety and flue gas in fluorine it is not exceeded, normal cement kiln preheaters system visitor after all
There is the preheater for realizing that Pyatyi exchanges trapping with Alkaline high-strength powder in sight;Nor the problem of alkali content is high, because often
Ton clinker consumption coal normally only 0.15~0.18t, the electrolyte in a small amount of cathode carbon pieces is mainly aluminum fluoride, calcirm-fluoride, fluorine aluminium
Sour sodium, fluoaluminic acid magnesium, sodium fluoride only account on a small quantity, dosage hour it is limited with the total alkali content in cryolite and sodium fluoride, typically
Influence to cement later strength is limited.Therefore, Shandong Aluminum Plant so far still can not be using negative electrode charcoal normal use as alternative combustion
The true cause of coal is:First the mill efficiency of coal mill is influenceed, is second that the graphitic carbon of low activity seriously reduces the whole of coal dust
Body combustibility, the serious normal combustion efficiency that have impact on coal dust, it is impossible to which the timely and effective exothermic charcoal element of burning is fallen into
Clinker entrains into the strong reduction of generation in powder, have impact on kiln system operating mode, have impact on clinker quality.Obviously, prior art is not still
Can be using electrolytic aluminium waste cathode carbon block as effective alternative fuel.
(5)Security landfill method:Because high energy consumption, high cost and secondary pollution problems be present in existing processing method, because
This, the problem of environmental pollution of electrolytic aluminium waste cathode carbon block is never effectively solved, and causes most aluminium electrolytics
Cathode carbon pieces are still thrown aside, and use the security landfill method of high cost at present or mainly.And the current landfill generally used, stockpiling
Method handles electrolytic aluminium solid waste method, high risks can be caused to environment, even completely by the harmless of hazardous waste
Lasting contact scar will be produced by changing landfill, and cause ample resources waste.
In addition, electrolytic aluminium solid waste is due to containing substantial amounts of soluble fluoride and a small amount of cyanide(Predominantly
Cymag and the sodium ferricyanide), belong to danger wastes, must be dealt carefully with.And under the conditions of prior art, electrolytic aluminium factory is universal
Landfill, the stacked arrangement of use handle these solid waste, and contained soluble fluoride and cyanide can pass through wind, day
The effect transfer that shine, drenches with rain is volatized into air, or be mixed into rivers with rainwater, permeate the ground contaminated soil and underground water, right
Animals and plants and human body produce very big infringement, destroy ecological environment, influence Agro-ecology balance, make crop production reduction, and it endangers will
It is long-term.Processing for cyanide in waste cathode carbon block, treatment technology mainly have weak acid dissolving+polysulfide to be converted into sulphur
For the method for cyanate and metal thiophosphate thing, manganese ion+ultraviolet catalytic oxidation method, ozone and sodium hypochlorite co-oxidation side
Method, high temperature chlorination processing method, high-temperature oxidation method, biochemical process processing cyanide technology.But at these existing cyanides
Reason technical method is cumbersome, cost is high, and secondary pollution be present.CN101811695A discloses a kind of from electrolytic aluminium waste cathode carbon block
The method of middle recovery graphite, it is that the process such as acidleach removes fluoride therein again using grinding, water logging, flotation, separates and recovers it
In carbon materials drying to obtain refined graphite powder.But this method process is numerous and diverse, secondary pollution is big, high energy consumption, the stone of recovery
Black fine powder impurity content is high.
To sum up, the outstanding problem as aluminum electrolysis industry general character, it is necessary to it is harmless to break through electrolytic aluminium solid waste as early as possible
