Description
Technical field
Electrolyte is refined the present invention relates to electrolytic cell carbon slag and aluminium ash utilizes technical field more particularly to a kind of electrolytic cell carbon
Slag refines the apparatus and method for that electrolyte and aluminium ash utilize.
Background technique
Electrolytic aluminium factory electrolytic cell can be due to quality problems in daily production process carbon block, the phenomenon that occurring carbon slag, its meeting
Influence the slot condition of electrolytic cell.It must be pulled out and.But carbon slag pulled out itself has inside many holes with a large amount of electrolysis
Matter.The electrolyte of recycling is used due to second-rate few people.But annual electrolyte is in great demand.Molten aluminum is from potroom
Foundry is drawn, is poured into holding furnace, the impurity of molten aluminum is to draw the electrolyte come out of electrolytic cell.When foundry produces
Slagging-off operation is carried out, after deslagging agent is added in surface electrolyte, becomes aluminium ash as rubbish.Handling aluminium ash is major Foundry Works
A great problem.Then the intermediate aluminium of normal handling method recycling becomes garbage disposal, some is made into addition water and is made into protection ring,
To protect steel pawl.But effect is poor, is not the use of many aluminium manufacturers, and aluminium ash and carbon slag need to handle every year hundreds of thousands even upper nearly hundred
Ten thousand tons.The problem of environmental problem is always electrolytic aluminium and aluminium deep processing maximum, most headache.There are two types of methods for processing carbon slag at present；
1, floatation.After electrolyte is removed iron, into fine-powdered in ball milling face, enters back into floatation equipment and carry out flotation.Into flotation fluid
Carbon dust lighter in weight is swum in afterwards, and electrolyte density is larger to be sunk in the following, after electrolyte separation, carries out oil removing, dehydration, drying
Or it dries.Product purity difference color burnt hair is produced, environmental pollution is big；2, baking.Common anti-projection furnace melts, a lattice in furnace
For fuel combustion, a lattice are molten bath.Carbon slag is put into molten bath, fuel generates high temperature and reaches 1200 degree or more, high temperature in burner hearth
And heat radiation makes the fusing of carbon slag Inner electrolysis matter flow to molten bath bottom.After when molten bath, Inner electrolysis matter liquid reaches certain height, open
Fire door releases high-temperature electrolysis matter.And beat surface scum.Since the electrolyte of bath is mixed with carbon dust, decomposition is not thorough,
The electrolyte flowed out from fire door does not separate also just to be solidified quickly, and surface whiteness is preferable, hence it is evident that better than the product of floating washing method.But it generates
Penetrating odor is big.Heat utilization rate is low.Carbon granules can also burn, aluminium ash processing method：A, ball mill is milled, aluminium therein
Grain becomes smaller aluminium flake under the rolling of steel ball.Again aluminium flake is screened out to come.Become garbage disposal, some progress are in next step：Aluminium ash adds
Water wheels grind, are slurried, extrusion forming, drying.Then it is made into annulus again into protection ring protection steel pawl.The disadvantage is that producing kind dust
It is larger, penetrating odor is larger when doing protection ring.B, blender heating stirring.Coal dust, carbon is added in the aluminium ash for just having taken off out
The pyrogens such as powder make aluminum shot become liquid aluminium outflow at high temperature.But a large amount of aluminium ashes become garbage disposal.It will not recycling benefit
With.We devise a kind of electrolytic cell carbon slag and refine the apparatus and method for that electrolyte and aluminium ash utilize to solve above-mentioned ask thus
Topic.
