Description
Technical field
The invention belongs to the stable processing technology field of incineration of refuse flyash, and in particular to be used as one by the use of composite biomass charcoal
The application of the environment-friendly fly-ash heavy metal fixative of kind.
Background technology
Flying dust refers to the material collected after waste incineration in recuperation of heat using system, flue gas purification system.The generation of flying dust
Amount is relevant with rubbish species, burning condition, the burning type of furnace and flue gas treating process, typically accounts for the 3%-5% of waste incineration amount
Left and right.Containing heavy metal and its esters and a variety of persistence organic pollutants such as substantial amounts of lead, zinc, cadmium, mercury in flying dust, wherein
Bioxin is the main organic pollution in flying dust.Dioxin be more chlorodiphenyls simultaneously-to-bioxin (PCDDs) and more chlorine two
The general designation of benzofuran (PCDFs), the concentration distribution of flying dust Zhong dioxin isomers have similar feature, high chloro two
The content of Evil English classes is apparently higher than low Lv Dai dioxins.It is the main next of environment Zhong bioxin to generally believe waste incineration at present
One of source.Pollutant in above-mentioned flying dust can migrate in the environment such as without processing after being directly entered environment, not only can be to environment
Produce serious influence, it is also possible to human body is entered by food chain, threatens health.China《Consumer waste incineration pollutes
Control standard》Flying ash is clearly classified as a kind of hazardous waste, it is necessary to carry out harmless treatment disposal.The annual city in China at present
City's rubbish output is at 1.8 hundred million tons or so, and 7% or so is burning disposal, and the yield of flying dust is based on 3%, the production of annual flying dust
About 37.8 ten thousand tons of raw amount, it is therefore desirable to which cheap, efficient technology carries out processing disposal to flying dust, reduces its environmental risk.
Elution and immobilization are two class main methods of pollutant in current processing flying dust.Elution refers to use water or water
Solution washs flying dust, reduces pollutant load so as to reduce its environmental risk, but is the product after high temperature incineration due to flying dust,
Metal occurrence patterns are complicated, therefore the simple aqueous solution is difficult to be washed out, thus need some chemical leachings to elute.And
The problem of also producing secondary pollution and water pollution after flying dust elution processing, thus the difficulty of flying dust elution processing is larger, cost
It is higher.Immobilization processing also referred to as stabilizes, and is after immobilization medicament is mixed with incineration of refuse flyash, to utilize immobilization medicament
Reaction with metal generates mineral or insoluble substance, so as to reduce the dissolution of heavy metal and organic pollution.It is existing solid
Determine chemical drug agent and be divided into inorganic stabilizers and the major class of organic stabilizer two.Conventional medicament has gypsum, phosphate, bleaching powder, vulcanization
Thing (sodium thiosulfate, sodium sulphate), macromolecule organic stabilizer, ferrite, clay mineral, N benzoyl N phenyl hydroxyamine etc..
Compared with inorganic stabilizers, organic stabilizer has the advantages of added amount of chemical is few, increase-volume amount is small, property is stable, but there is also
The problem of selling at exorbitant prices causes using being limited.Thus while laboratory research shows the good fixing effect of organic fixative, but by
And not large-scale industrial production and use high in cost, and it is general all effective just for inorganic heavy metal, but for
The fixed effect of organic pollution such as bioxin is bad.
Therefore, although flying dust immobilization processing is a kind of simple possible, the flying dust processing mode of non-secondary pollution, need
To be directed to that pollutant type in flying dust is more, the big feature of harm, develop wide spectrum, new, cheap, efficient immobilization medicament.This
It is the current key for influenceing the development of flying dust immobilization treatment technology and promoting waste incineration development.But so far, not yet send out
The research report of existing energy while the domestic garbage incineration flyash fixative of immobilization organic pollution and various metals, does not also find
Application study of the composite biomass charcoal in flying dust processing.

With the stretching vibration of hydroxyl (- OH)；In 1635~1637cm-1Characteristic peak is titanium tungsten powder absorption water H-O-H flexural vibrations；
1401cm-1The absworption peak at place is stretching vibration red shift (the standard value 1415cm by W-O-H-1) cause, this is due to W valency
Caused by state is varied from；In addition, in 1138cm-1、1047cm-1Nearby all there is small absworption peak, be W-Od (end oxygen root) respectively
Stretching vibration, the flexural vibrations of hydrone.Because the major absorbance peak of tungsten oxide is in 900~500cm-1Between, in IR collection of illustrative plates
400~600cm of Ti-O-Ti flexural vibrations peaks is removed in this segment limit-1Outside, not obvious absworption peak, shows in titanium tungsten powder
The distribution of tungsten is mainly to substitute part Ti4+In the presence of one side W6+It may replace part Ti4+, ion cavities are formed, are reduced
TiO2Energy gap；Another aspect WO3And TiO2Between occur redox reaction, produce such as W6+、W5+、W4+And Ti4+、Ti3+
Etc. the ion of different valence state, increase TiO2In oxygen ion vacancy.This is to produce 1138cm-1,1047cm-1Neighbouring small absworption peak

3rd step, prepare titanium tungsten powder carrier base-material；
4th step, each composition above is mixed according to aforementioned proportion, stirred.
7. using the method for any one of claim 1 to the 5 flying dust compound stabilizer processing domestic garbage incineration flyash, it is special
Sign is：Domestic garbage incineration flyash is added into reactor first, then the compound stabilizer is added in reactor, flying dust
The addition of compound stabilizer is the 0.5%~5% of flying dust weight, and persistently stirring 10~20 minutes makes composite biomass charcoal rubbish
Flying ash compound stabilizer and flying dust are sufficiently mixed；Then spray the water of 10~20% percentage by weights and be stirred for 15~30
Minute, make composite biomass charcoal incineration of refuse flyash compound stabilizer and heavy metal in flying dust and organic pollution fully anti-
Should, finally products therefrom is cured at normal temperatures, air-dried, produces stabilizing fly ash product.
