Description
Technical field
The invention belongs to resource circulation utilization field, it is related to the method for comprehensive utilization of a kind of spent acid, alkaline residue and dedusting ash.
Background technology
Steel plate is the important raw and processed materials of auto industry, household electrical appliance, Container Transport and Welded tube production industry.Due to putting
The surface of steel plate put too long often forms one layer of iron scale, therefore is required for removing this layer through overpickling before cold-rolling of steel plate
Iron scale, will so consume substantial amounts of hydrochloric acid, so as to generate substantial amounts of waste hydrochloric acid.In general, cold rolling mill produces
The content of free hydrochloric acid is about 10wt% in the spent acid gone out, and the content of free iron is about 20~30wt%, while is also contained
A small amount of nickel ion and cobalt ions；By taking a middle-size and small-size cold rolling mill as an example, its daily up to tens of to up to a hundred ton of spent acid amount, and
The method of the spent acid of processing cold rolling mill output mainly has neutralisation, roasting method, evaporation and sulfate substitution method etc. at present.
Neutralisation is to be reacted using substantial amounts of lime with hydrochloric acid until reaching and can directly be discharged after discharge standard.This method exists
Consume large quantities of lime at the same time, also result in the waste of the hydrochloric acid and frerrous chloride in a large amount of spent acid.Fe2 contained in waste liquid after discharge
+ be oxidized to Fe3+ after water body is changed into brown, cause soil hardening, seriously affect ecological environment.Therefore, neutralisation is a kind of
The method of pollutant transfer, is only applicable to handle a small amount of pickle liquor.
Roasting method is by the hydrochloric acid in high-temperature roasting waste acid recovery, while generation such as iron chloride or ferric oxide particles.Should
Method mainly has spray roasting and fluosolids roasting method.Spray roasting is by the way that spent acid is sprayed by the nozzle of roast furnace top
Enter in stove, put the direct-fired mode of coal gas in burner, finally spray obtains hydrochloric acid of living again from tail gas, and furnace bottom obtains iron oxide
Particle.The calcination temperature of this method is generally at 600-800 DEG C.Fluosolids roasting method is that spent acid is sprayed into the flowing molten iron medium containing oxidation
In fluid bed, coal gas lights heating by bottom, finally obtains live again hydrochloric acid and ferric oxide particles.This method advantage is that hydrochloric acid returns
Yield is big, concentration is high, and the concentration of hydrochloric acid of recycling is 20% or so；Shortcoming is that investment is high, including is taken up a large area, equipment investment
High, operating cost height, civil engineering, complex structural designs, further include the supply of heat source, cooling water.Gained ferric oxide particles are miscellaneous at the same time
Quality is big, and purity is not high with causing price.Due to its so high input and energy consumption, it is merely capable of being used in large-scale acid at present
Among washing machine group.
Evaporation is to evaporate spent acid under subnormal ambient, and hydrochloric acid and water are evaporated from spent acid, is recycled by cooling
Hydrochloric acid.Gained concentrate crystallisation by cooling, finally obtains about 22% or so hydrochloric acid and frerrous chloride crystal after separation of solid and liquid.Should
Method advantage is：The investment of civil engineering and equipment is smaller, without very complicated structure.But its production cycle is longer, treating capacity is not
Greatly, and gained concentrated mother liquor is needed to return after separation of solid and liquid and distilled, and energy consumption (steam, electricity etc.) is higher, is suitable for steel wire, steel pipe
And the less small-sized pickling unit of the spent acid amount such as steel tower.
Sulfate substitution method is based on evaporation, and the concentration of hydrochloric acid obtained by evaporation is relatively low, is added in spent acid
Enter sulfuric acid, sulfuric acid and frerrous chloride occur displacement reaction, finally obtain ferrous sulfate and hydrochloric acid.Afterwards by negative pressure evaporation,
Separation of solid and liquid obtains the higher hydrochloric acid of concentration and errous sulfate crystal.Concentration of hydrochloric acid obtained by this method is higher, while obtains sulfuric acid
It is ferrous.But it is complete reaction between ions, therefore there are hydrochloric acid and sulphur at the same time in gained acid solution since the reaction is displacement reaction
Sour ferrous, separating difficulty is larger.Simultaneously because ferrous sulfate is soluble matter, its solubility is 66.67g, and therefore, separation has certain
Difficulty, cause gained hydrochloric acid concentration be less than theoretical concentration.If excess sulfuric acid, a certain amount of sulphur can be contained in recovery acid
Acid, i.e., usually obtain nitration mixture, severe corrosion equipment.Further, since adding sulfuric acid, cost is caused also accordingly to increase, also can shadow
Ring benefit
Large type chemical products based on soda ash, since being born at the end of the 19th century, the just progress tribute to world industry
Immense strength is offered.Between 2010~2014 years, China's soda ash production capacity is by 26,400,000 tons of enlargings in the end of the year 2010 by 2014
33000000 tons, average growth rate per annum about 5.2%, becomes the first in the world soda manufacture big country.It is but associated with " whole world eldest child " ring of light
Accompany, be alkaline residue discharge capacity first.Although China has been gradually reduced using the proportion of ammonia-soda process soda ash, yield accounting is still near
Five to sixty percent or so.According to this ratio, the soda ash that ammonia-soda process produces is 1400~17,000,000 tons or so.In the industry it is believed that
10 cubic metres of waste liquids, wherein solids content (butt) about 3% will be discharged by often producing 1 ton of soda ash.So, it is pure using ammonia-soda process
Alkali will produce 450~5,000,000 tons of alkaline residues.Contain a large amount of chlorions in alkaline residue, pH value is higher, the meeting again under the effect of the showers such as rainwater
Enter soil, polluted underground water with water.Alkaline residue is since the technique of invention ammonia-soda process alkaline, its caused environmental problem,
It is always century problem in global range.At present, the developed country such as America and Europe avoids alkali by way of eliminating ammonia-soda process
The pollution that slag is brought.But China is since the limitation of technology and resource, ammonia-soda process can not still be eliminated completely, therefore, to handle number
Amount so huge alkaline residue, needs professional equipment that acquisition price is high and puts into high operation and maintenance cost.In face of cost,
Each alkali factory to alkaline residue with regard to without any processing, directly by alkaline residue accumulation river bank by the sea, so will certainly land occupation, but also
Entail dangers to navigation channel, causes the different degrees of pollution in marine site, river and silts up, or even jeopardizes culture fishery.
Dedusting ash (also known as blast furnace dust, cigarette ash or flue dust) is as blast furnace gas carries out in blast furnace ironmaking process
Raw material dust and high-temperature region intense reaction and the particulate that produces through product obtained from dry dust removal, be the by-product of steel and iron industry
Product.Its main component is iron oxide and carbon, also there is the non-ferrous metal of recovery value containing a small amount of zinc, lead, indium, potassium, sodium and bismuth etc..
According to statistics, about 20 kilograms of dedusting ash containing zinc 10%~20% will be produced by often producing l tons of iron, by China's Tangshan production steel in 2012
1.7 hundred million tons of calculating, the year quantum of output of Qian'an dedusting ash is estimated at 17,000,000 tons, converts into 680,000~1,360,000 tons of metal Zn content, about
Equivalent to the yield of 11,000,000~22,000,000 tons of zinc ores.Meanwhile China is the country of potassium resource famine again, therefore often
Year can also recycle 850,000~1,300,000 tons of sylvite and as the raw material of chemical fertilizer.
With China's rapid development of economy, the demand of metal material is constantly expanded, the consumption drastically expanded triggers
The serious problems of each side such as resource, the energy and environment, become an important factor for restricting Chinese society and sustainable economic development.
Therefore, metal secondary resource is carried out recycling research, develops the high efficient separation technology of secondary resource and recycle skill
Art, carries out the recycling to dedusting ash, the resource of preciousness is fully utilized, can also mitigate solid and give up
Expect the pollution to environment.If dedusting ash resource is not fully utilized, a large amount of soils can be not only taken, are also necessarily caused to environment
Detrimental effect；Secondly, rising steadily with iron ore and metallic zinc price, if recycled not from dedusting ash iron, zinc,
The valuable elements such as lead, potassium, sodium are taken in reduce ironmaking cost and increase, certainly will be a kind of huge wastes to dedusting ash.
It can be seen from the above that spent acid, alkaline residue and dedusting ash are all trade wastes, belong to three industrial wastes.If arbitrarily stack without
If rationally disposal or recycling, serious pollution will certainly be caused to surrounding environment, while can not recycle a variety of valuable
Metal.
