Abstract
The invention discloses a method for aluminum ash treatment and recycling use. Through combination of an aluminum ash heat recovery process and an aluminum ash cold recovery process in a current production system and utilization of a dedusting system and multiple waste use processes, the method effectively solves the problem that environmental pollution, resource wasting and a cost are increased, realizes recycling use of treated alumina and fluoride salts, and has obvious economic benefits.
Description
Technical field
The present invention relates to the method for the processing of a kind of aluminium ash and recycle, relate to chemical field.
Background technology
Except containing aluminium, also contain Al in the aluminium ash
2O
3, fluoride salt, CaO and SiO
2Deng material, the aluminium in the aluminium ash can reclaim, if with other composition jettisoning, not only increase cost, also can cause severe contamination to environment.Therefore need the Technology of the processing of a kind of aluminium ash and recycle, the aluminium in the aluminium ash is reclaimed the founding ingot of laying equal stress on, Al
2O
3Again be added to recovery such as fluoride salts and carry out recycle in electrolyzer, also can be made into anode steel claw protection ring, for the protection of the steel pawl and carry out recycle.
At present, the method for domestic aluminum ash processing can be divided into thermal treatment absorption method and the large class of deepfreeze absorption method two substantially.The thermal treatment absorption method is that the aluminium ash that will just claw from smelting furnace is placed on stir-fry ash pot, utilize the heat of aluminium ash self, stir-fry with machinery, molten aluminium little by little is pooled to the bottom of iron pan in the process that stir-fries, and then with the steel spoon, it is scooped out and casts aluminium ingot.The deepfreeze absorption method is to use vibratory screening apparatus to sieve processing to the aluminium ash, makes aluminium and Al
2O
3, the separating substances such as fluoride salt.
Current, it is all individual workship basically that domestic aluminium ash is processed, recovery method is simple, be all the open type operation, produce a large amount of dusts, fluoride salt produces a large amount of smog, seriously polluted, although aluminium is recovered utilization, other compositions such as aluminum oxide and fluoride salt are all regarded the waste material jettisoning, can not recycle.Therefore, the aluminium of Present Domestic ash treatment process technology is contaminate environment, is not recycle.
Summary of the invention
The present invention is directed in the past that the processing of aluminium ash can produce dust, smog causes environmental pollution, the insufficient waste material of leaving over of aluminium ash recycle causes the problem of the wasting of resources, cost increase and contaminate environment, the invention provides the method for the processing of a kind of aluminium ash and recycle, effectively solved by the operation of repeatedly utilizing that increases dust-removal system and waste material the problem that environmental pollution, the wasting of resources and cost increase.
To achieve these goals, the present invention adopts following technical scheme:
A kind of aluminium ash is processed the method with recycle, and the method comprises the following steps:
A, under dustproof and closed environment, the hot aluminium ash that will claw from the founding smelting furnace is poured in the reactor of aluminium liquid recycling machine, adds slag former in this reactor, start the agitating vane of this aluminium liquid recycling machine, after fully stirring, the aluminium that recovery obtains is sent in the founding smelting furnace remaining waste residue;
B, under dustproof and closed environment, the waste residue in step a is sent in cold slag crusher broken, the cold slag after fragmentation is sent into cold grey stockyard;
C, in dustproof environment, the cold ash in cold grey stockyard in step b is carried through worm conveyor, chapelet promotes, and sends into feed bin;
D, in dustproof environment, the cold ash in step c feed bin through the electromagnetic feeder feed, is sent into ball mill grinding, the powder material after grinding filters out aluminum oxide, fluoride salt and aluminum particulate through trommel screen, vibratory screening apparatus, and aluminum particulate is sent into the founding smelting furnace;
E, under closed environment, with the mixture of the aluminum oxide in steps d and fluoride salt store, transportation, proportioning is sent in charging system as calculated.
Further, be provided with dust-removal system in described production process, production unit is equipped with dust gathering arrester.
Further, described dust-removal system is the two-stage dedusting that is combined by cyclone dust removal and pulse bag-type dust-removing.
the beneficial effect that the invention provides technical scheme is: the recovery of heat of aluminium ash is processed with cold recycling being integrated in a straight-lined manufacturing system, the mechanization degree of straight-lined manufacturing system is high, avoided human error, this system also can be with the waste material recycle again of links, effectively improved production efficiency, production process is provided with dust-removal system, production unit is equipped with dust gathering arrester and has realized dustproof and airtight effect, avoided environmental pollution, ball mill, the application of trommel screen and vibratory screening apparatus, filtered out aluminum oxide, fluoride salt and aluminum particulate, particularly process the materials such as rear oxidation aluminium and fluoride salt and obtain recycle, remarkable in economical benefits.
