Description
Technical field
The present invention relates to a kind of artificial quartz in lump more particularly to a kind of electrolytic aluminium ash system's artificial quartz in lump and its making sides
Method.
Background technology
Aluminium ash result from electrolytic aluminium, secondary aluminium processing etc. all aluminium in producing process generated slag through cooling
Product after processing is a kind of renewable resource containing aluminium and a variety of valuable elements.Its source can be divided into aluminium electroloysis smelting process
Aluminium ash in the aluminium ash of middle generation, the aluminium ash and secondary aluminium process in aluminium fusion-casting process.Aluminium ash mainly by metallic aluminium simple substance,
The mixture of oxide and salt solvent forms, wherein 10%-30% containing aluminium, aluminium oxide 20%-40%.If not recycled profit
With not only waste of resource, but also pollution environment.
Aluminium and other valuable elements are recycled from aluminium ash, are fully and rationally used, to improving the economic benefit of enterprise, protection life
State environment has important practical significance and practical value.It is recycled with current technology aluminium ash, wherein having a kind of method just
That grinding operation is carried out by aluminium ash ball mill, the aluminium ash material after grinding may be used as steel-making deoxidier (containing aluminium 30% with
On aluminium ash) or be processed as aluminium polychloride be also referred to as aluminium chloride (PAC) other manufacture fields use.
There is a method in which being exactly " frying grey absorption method "：Its detailed process is that the aluminium ash that will have just raked off is placed in iron pan
Using the grey heat of itself of aluminium, stir-fry, the substances such as magnesium, which continue oxidation heat liberation, makes the temperature of aluminium ash increase.Due to aluminum melt with
The wettability of other materials is bad in aluminium ash, and aluminum melt is gradually pooled to the bottom of iron pan during stir-frying, then will
It takes out and casts aluminium ingot, is used as foundry returns.This method belongs to open type operation, generates a large amount of dust, especially
It is added after zinc chloride etc., will produce aluminium chloride, absorb moisture in air, a part forms hydrogen chloride, generates a large amount of cigarette
Mist is harmful to environment, therefore should set up exhaust fume collecting hood, increase the equipment such as dust collection device and spray, is carried out to the flue gas of generation
Effective environmental protection treatment.
For aluminium ash after one or many recycling aluminium, aluminium content is very low, mainly contains aluminium oxide, iron in aluminium ash at this time
The chloride etc. of silicon magnesium oxide, potassium sodium calcium and magnesium, still can further comprehensively utilize.For example, can be used to prepare ceramic gaged brick.
Using aluminium scrap ash as primary raw material, a certain amount of clay, quartz and the additive for reducing firing temperature are added, can be prepared high performance
Ceramic gaged brick.Aluminium ash can also be mixed using Load materials are made with Cab-O-sil, is sintered at 1350 DEG C, is made and is laid with road
The material in face, hardness are 1.5 times of prevailing roadway material, and anti-slide performance is 1.2 times of the general material that paves.
Aluminium ash is also easy to produce the high-risk chemicals such as ammonia, hydrogen fluoride, cyanide in generation and disposal process.Due to lacking society
The unified technology of meeting benefit, environmental benefit, economic benefit three, the processing of China's Aluminum ash is at present still in more original
Primary stage, real situation is that quite a few aluminium ash is unprocessed and be buried or arbitrarily abandon, not only in aluminium ash
Useful component cannot be comprehensively utilized effectively, but also it is serious polluted environment, not with the theory pole of current Green Development
Match.
As the electrolytic aluminium big country that world's production capacity and yield rank first, Chinese electrolytic aluminium, aluminium processing, secondary aluminium are every
The conservative estimation of the aluminium ash quantity of year discharge is at 3,000,000 tons or more, and plus stockpiling for many years and burial, quantity has been cured ten million ton.
