Description
Technical field
The present invention relates to a kind of incineration of refuse flyash mineralization treatment methods, belong to dangerous waste processing field of engineering technology.
Background technique
Existing more than 100 years history of incineration treatment of garbage, incineration method processing house refuse are to realize that minimizing most fast has
The technical method of effect not only thoroughly eliminates harmful bacteria and virus, and recoverable energy is secondary promotes the well-being of mankind, but waste incineration
Also secondary pollution problem is produced；Secondary pollution is mainly in the flying dust of waste incineration generation comprising dioxin contamination
The heavy metal pollution problems such as cd.AS.Hg.rb cause the flying dust excluded that cannot efficiently use；But due to containing pollution in flying dust,
Therefore, national clear stipulaties flying dust category dangerous waste object must not be discharged arbitrarily, after this just carries out carry out chelation treatment to flying dust, taken and filled out
The processing modes such as bury, but this Landfill occupies a large amount of soil, pre-processing is up to standard, but whether the later period generates two
The secondary all bad control of pollution, in addition, China's conventional garbage incinerator has broken through 1000, generates a large amount of flying dust every year, therefore,
It needs that technological means is taken to carry out secondary use to flying dust and makes place mat, in the hope of effecting a permanent cure.
For the secondary use for realizing flying dust, the more method handled flying dust and material exists in the prior art,
But there is complex process, operating difficulties, problem with high costs in these methods, and need to carry out needle using specific environment more
The product that technology is unable to drive garbage burning factory can not be brought up in the defect of garbage burning factory treatment in situ, these problems to property processing
Polarity, though lead to have technological means, the predicament that can not effectively promote.
Summary of the invention
For the defect for solving the prior art, the present invention provides a kind of flyash treatment method of simple process, and the present invention only needs
Flying dust is stirred and processing to flying dust can be realized in local use waste incinerator secondary clacining, and be made it is subsequent can benefit
Material, it is low in cost.
To achieve the above object, the invention adopts the following technical scheme: a kind of incineration of refuse flyash mineralization treatment method, right
Mineralizer and aqueous solvent is added in the flying dust that waste incinerator generates, and forms mixture, will be made in mixture merging particle machinery
Spherical solid granulates, and spherical solid granulates are returned in waste incinerator and carry out secondary clacining；
The mineralizer includes potassium feldspar fine powder, spodumene fine powder, magnesia, land plaster, ball clay and Alusil.
Preferably, with mineralizer poidometer, the weight ratio of mineralizer constituent is respectively potassium feldspar fine powder 5-15%, lithium
Pyroxene fine powder 5-15%, magnesia 2-8%, land plaster 5-15%, ball clay 10-25%, Alusil 35-55%.
Preferably, with mineralizer poidometer, the weight ratio of mineralizer constituent is respectively potassium feldspar fine powder 10%, lithium brightness
Stone fine powder 10%, magnesia 5%, land plaster 10%, ball clay 18%, Alusil 47%.
Preferably, aqueous solvent includes emulsifier and water-reducing agent, and the emulsifier and water-reducing agent using commercial emulsifier and subtract
Aqua.
Preferably, with flying dust poidometer, the weight ratio of aqueous solvent constituent is emulsifier 0.05-0.3%, water-reducing agent
0.1-0.4%。
Preferably, with flying dust poidometer, the weight ratio of aqueous solvent constituent is emulsifier 0.1%, water-reducing agent 0.15%.
Preferably, the partial size of potassium feldspar fine powder and spodumene fine powder is 50 μm of micro mists and Ultramicro-powder below.
Preferably, with flying dust poidometer, the mineralizer accounts for the 5-15% of flying dust total weight.
Compared with prior art, it is special using the extra specific surface area of Alusil that the beneficial effects of the present invention are: the present invention
Point wraps flying dust, and the harmful substance in flying dust is prevented to be precipitated, and promotes Alusil and flying dust to make in high temperature by spodumene
With lower generation tuberculosis, while reducing the dry of tuberculosis using the high viscosity feature of potassium feldspar and shrinking and deformation, ball clay as with
The matrix of flying dust bonding, assists sintering at high temperature, the addition of land plaster, magnesia can be effectively to ball clay and flying dust
Bonding carry out normal temperature cure, obtain some strength at normal temperature, irreversible reaction, subsequent warp generated after mixture high temperature mineralising
Processing flying dust can be used as construction material use.
Specifically embodiment
The flying dust 60KG for taking waste incinerator to generate, and be put into Particle mixer, the mineralizer of following components: potassium is added
Feldspar fine powder 0.6KG, spodumene fine powder 0.6KG, magnesia 0.3KG, land plaster 0.6KG, ball clay 1KG, Alusil 2.8KG,
It carries out dry-mixed, stirs, aqueous solvent odium stearate 0.06KG and naphthalene sulfonate water-reducing agent 0.09KG is added, is sufficiently stirred
Uniformly, the orbicule of 3 centimetres or so of diameter is made, orbicule is subjected to static solidification in 24 hours, is then sent to waste incineration
It is sintered in furnace, sintered flying dust is mineralized object package, is discharged with clinker, as can built again using material
It is used in field as raw material.
In the above-described embodiments, the partial size of spodumene and potassium feldspar is smaller, and raw material obtained will have better effect.
It is clear that above embodiment is only one of demonstration example of the invention, it is any provided by the present invention
Simple modifications in structure or principle will fall into protection scope of the present invention.
