Description
Technical field
This utility model relates to a kind of aluminium cell slag from delining innocuity disposal system, belongs to electrolytic aluminium offal treatment skill
Art field.
Background technology
Containing cathode block, refractory brick, bundle paste, insulating brick, refractory powder, fire mortar, thermal insulation in aluminium cell slag from delining
Plate, the metal of infiltration and electrolyte and a small amount of aluminium nitride and cyanide salt, its composition includes 33% by weight percentage
Carbonaceous material, 30% fluorine-containing material, 34% flame-proof thermal insulation material and other materials on a small quantity, because it contains the fluoride of solubility and few
The cyanide of amount, is listed in hazardous waste.The generation amount of aluminium cell slag from delining increases along with the yield of electrolytic aluminium and increases, because of
This, it is necessary to carry out harmless treatment.
In traditional processing mode, landfill disposal is the mode that application is more, but this method environmental pollution is serious.
In order to avoid environmental pollution, the many employings of domestic aluminium manufacturer are built ne-leakage stacking field and are carried out concentrating stacking, it is reported, current China has
Electrolytic aluminium waste gurry more than 2,000,000 tons is piled up, and these deposits are not only caused by building and safeguard the cost stacking place
Increase.
Authorization Notice No. is the Chinese utility model patent (authorized announcement date is on June 10th, 2015) of CN103239828B
Disclosing a kind of electrolytic aluminium slag from delining hamlessizing technology technique program control, manual, this technique uses and adds except cyanogen agent, the side of defluorinating agent
Formula carries out harmless treatment to electrolytic aluminium slag from delining, and concrete employing is separately added into except cyanogen agent and fluorine removal in two agent bins
Agent, by making powder through broken and except ferrum slag from delining, adds in reaction warehouse, the powder in reaction warehouse carries out preliminary examination, inspection
Survey its cyanide content, content of fluoride, pH value, then add appropriate reacting except cyanogen agent according to the content of cyanide and remove cyanogen,
Detection concentration of cyanide is qualified less than 0.5mg/L, and the content further according to fluoride adds appropriate defluorinating agent and acid, reacts
Fluorine removal, to fluoride concentration less than 10mg/L, pH value is qualified when 6-7, and the slurry in reaction warehouse is squeezed into Buffer Pool, will be slow
Rushing the slurry in pond and squeeze into pressure filter, the water that pressure filter is separated imports after filter tank filters and is back in cistern again make
With, Filter Press dry pug out is the slag from delining after harmless treatment.
The device that the method uses includes A agent bin, B agent bin, acid-regulating tank, reaction warehouse, wherein A agent bin and B reagent
Storehouse is all connected with reaction warehouse by conveying worm, and acid-regulating tank is also connected with reaction warehouse.It prepares slurry, slurry leaches and removes cyanogen
Can only carry out in same reaction warehouse with fluorine removal process, be unfavorable for carrying out continuous processing, can only increase to improve treatment effeciency
The capacity of big reaction warehouse, and it is too much to process slurry in single reaction warehouse, then it may be caused to remove cyanogen fluorine removal and react uneven, reaction
Speed declines, and in turn results in treatment effeciency and declines, and therefore this processing means is to electrolytic aluminium slag from delining harmless treatment efficiency relatively
Low.Same, its butanedionedioxime operationally, its slag from delining raw material, except cyanogen agent is simultaneously introduced mixing, prepare slurry, leaching
Slurry cannot separate with except cyanogen process, and raw material, each reactant affect its reaction efficiency, also cause together with being mixed in product
Its reaction is thorough not, reduces treatment effect.
