With the raising of Chinese Urban Residents living standard and urban modernization degree, Chinese Disposal of Domestic is just located
In the transitional period from based on landfill to based on burning.Year ends 2015, national consumer waste incineration processing total amount reach 6577
Ten thousand tons, account for the 34% of harmless treatment total amount.According to relevant report, the year two thousand twenty is arrived, consumer waste incineration processing capacity accounts for innoxious
The ratio of processing capacity reaches 50%, and house refuse is averaged day output up to 59.1 tons, then can generate 650~11,000,000 every year
The incineration of refuse flyash of ton.
Since a large amount of bioxin and heavy metal can be enriched in flying dust in Refuse Incineration Process, both at home and abroad all rubbish
Rubbish flying ash is disposed as dangerous solid waste.In incineration of refuse flyash solubility salt typically constitute from 10%~
25%, including chloride, sulfate, carbonate etc..It is waste incineration that dioxins materials are enriched in incineration of refuse flyash
The strongest substance of flying dust Poisoning, content generally in 0.034~7.53ng-TEQ/g, be 100 times of general soil background value with
On.In addition, also contain heavy metal element in incineration of refuse flyash, such as Zn, Pb, Cu.Disposition waste incineration both at home and abroad flies at present
The method of ash fills after mainly curing or seal, but has many researchs by incineration of refuse flyash for cement, pitch, sintering
The auxiliary material of the energy saving building materials such as haydite, fired brick.And can not degrade bioxin as construction material doping auxiliary material, Dui bioxin
Certain diluting effect can only be played with heavy metal element, the degree of recycling is also restrained.
Invention content
The purpose of the present invention is to provide a kind of method of Copper making treating incinerated fly ash of domestic garbage with cooperation, this method behaviour
Make simply, to realize harmless treatment and the recycling of incineration of refuse flyash, reduces the cost of Copper making, it is dirty to reduce environment
Dye.
The present invention solves its technical problem using following technical scheme to realize：
The present invention proposes a kind of method of Copper making treating incinerated fly ash of domestic garbage with cooperation, including：
Incineration of refuse flyash after washing and drying is subjected to melting with copper concentrate, incineration of refuse flyash main component includes
CaO and SiO2, contain bioxin and heavy metal element simultaneously.
The present invention proposes that a kind of method of Copper making treating incinerated fly ash of domestic garbage with cooperation is comprehensive in metal smelt and resource
Close the application in utilizing.
A kind of method of Copper making treating incinerated fly ash of domestic garbage with cooperation of the embodiment of the present invention and the beneficial effect of application
Fruit is：
Incineration of refuse flyash is used as Copper making slag former by the present invention, mixed with copper concentrate instead of lime stone and quartz sand etc.
Close melting, by the high temperature that is generated in fusion process can efficient-decomposition incineration of refuse flyash Zhong bioxin, reach waste incineration
The purpose of flying dust removing toxic substances, reduces processing cost, the copper pyrometallurgy cost of incineration of refuse flyash, reduces environmental pollution.This method
Easy to operate, process cleans realize harmless treatment and the recycling of incineration of refuse flyash, turn waste into wealth, reduce stack,
The environmental problem that landfill etc. is brought.
Specific implementation mode
It in order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below will be in the embodiment of the present invention
Technical solution be clearly and completely described.The person that is not specified actual conditions in embodiment, builds according to normal condition or manufacturer
The condition of view carries out.Reagents or instruments used without specified manufacturer is the conventional production that can be obtained by commercially available purchase
Product.
Below the method to a kind of Copper making treating incinerated fly ash of domestic garbage with cooperation of the embodiment of the present invention and application into
Row illustrates.
A kind of method of Copper making treating incinerated fly ash of domestic garbage with cooperation provided in an embodiment of the present invention, including：
The incineration of refuse flyash of certain municipal solid waste incinerator is chosen, in the present invention, the ingredient such as table of incineration of refuse flyash
1。
1 chemical component table of table
In the present invention, the research through inventor finds to contain a certain amount of CaO and SiO in incineration of refuse flyash2, can
To substitute the lime stone and quartz sand during Copper making, the cost of Copper making can be not only reduced, can also turn waste into wealth, subtract
The environmental problem that few stacking, landfill etc. are brought.The high temperature generated during Copper making simultaneously can efficient-decomposition waste incineration
Flying dust Zhong bioxin achievees the purpose that incineration of refuse flyash detoxifies, reduces the processing cost to incineration of refuse flyash, reduces ring
Border is polluted, and realizes the harmless treatment of incineration of refuse flyash.
In order to improve CaO and SiO in incineration of refuse flyash2Content, to copper concentrate carry out melting before, washed
It is dry.Specifically, after incineration of refuse flyash is washed 0.5~1.5 hour under conditions of 20~30 DEG C, in 60~80 DEG C of item
It is 1~3 hour dry under part.Washing can elute a large amount of solubility salt in flying dust, by Ca in the incineration of refuse flyash of washing,
Si equal sizes increase, and K, Na, Cl equal size reduce, and will not be impacted to melting slagging process.Specific ingredient such as table 2.
