Description
Technical field
The utility model relates to chemical technology fields, specifically, be related to that a kind of secondary aluminium scrap ash prepares aluminium stone be
System, belongs to the reclaiming technology of secondary aluminium scrap ash.
Background technique
Aluminium scrap ash is to produce a kind of lime-ash generated in primary aluminum or aluminium product process, the higher metallic aluminium of intrinsic value
And aluminium oxide, it is taken seriously since a secondary aluminium ash has biggish economic value as a kind of resource, corresponding reclaiming
Technological means is also more therewith, and secondary aluminium scrap ash mentions the residue after aluminium as a secondary aluminium ash, there is no at present effective secondary
Aluminium scrap ash reclaiming technology, but the production quantity of the secondary aluminium scrap ash in the whole world is but in continuous quickly increase, therefore secondary aluminium scrap is grey
Problem is global problem.
Existing secondary aluminium scrap ash processing means are typically all to fill, stack or even be directly injected into river, are endangered as follows:
(1) filling type processing harm: secondary aluminium scrap ash processing in the prior art is mostly using the method for landfill, due to two
Pollutant contained by secondary aluminium scrap ash can serious contaminated soil, cause the abnormal even variation of plant growth；
(2) stacking type processing harm: secondary aluminium scrap ash is directly deposited in roadside by some aluminum fabrication plants, is allowed to wind rain
It beats, is absorbed by the body in air if drifted, will lead to memory reduction, serious person causes dementia concurrent；
(3) injection river harm: secondary aluminium scrap ash is then directly poured into river by some aluminium processing enterprises, and harm is just bigger,
Serious pollution water quality causes shoal of fish body dead or aquatic products poisoning, brings immeasurable loss to the people's lives and property.
In the prior art, the only reclaiming technology of secondary aluminium scrap ash is aluminium ash ball (AD powder) technology, water purification agent (original
Name flocculant) technology, cell technologies are returned, but there is serious technical defects as described below:
(1) it aluminium ash ball (AD powder) technology: when aluminium scrap ash secondary using aluminium ash ball (AD powder) technical treatment, can generate a large amount of
Ammonium hydroxide and sulfuric acid waste；
(2) water purification agent technology: water purification agent original name flocculant, when aluminium scrap ash secondary using water purification agent technical treatment, mainly according to
Rely pickling and washing, not only a large amount of acid of waste and water resource, while can also generate a large amount of ammonium hydroxide and sulfuric acid waste, the technology
In the last century eighties, explicit order has been disabled in China；
(3) cell technologies being returned: when using returning the cell technologies secondary aluminium scrap ash of processing, relying primarily on pickling and washing,
The not only a large amount of electricity of waste, acid and water resource, while it is useless also to generate a large amount of waste ammonia liquor, sulfuric acid waste and fluoride
Slag.
The reclaiming technological means of above-mentioned secondary aluminium scrap ash not only causes the serious wasting of resources, and can all generate big
The pollutant of amount, and polluted natural environment, endanger public health, the theory with current green ecological and sustainable development
It is extremely unbecoming.In addition, its process cycle is also very long, and needs expensive special equipment and matches professional, simultaneously also
Can only the reclaiming of small lot ground, therefore do not have market popularization value.
