Abstract
The present invention relates to a flyash fusing additive for refuse incineration treatment. The present invention is made of 30 to 50 percent of B2O3, 25 to 40 percent of SiO2, 7 to 20 percent of CaF2 and 7 to 20 percent of MgO by weight to be mixed and ground into 106 to 256 meshes, and 2 to 5 percent of ZrO2 can be added to the mixture. The present invention adds the proper flyash fusing additive to refuse flyash, can effectively reduce fusion temperature, reduces volatilization of inorganic salts, simultaneously increases the solidification effect of heavy metals of a glass body, strengthens various physical properties for liquid slag, is suitable for resource utilization of the liquid slag, and promotes popularization of the technique for fusing and solidifying flyash.
Description
Technical field
The invention belongs to the Solid Waste Treatment technical field, the improvement of the additive for fusing in particularly a kind of melting and solidification technology.
Background technology
The melting and solidification technology is advanced both at home and abroad at present incineration of refuse flyash method for innocent treatment, and fusing fly ash solidifies to handle can thoroughly eliminate De bioxin in the flying dust, guarantees the long-time stability of curing heavy metal, reduces the volume of flying dust greatly; Simultaneously, liquid slag can be used as materials such as building, building, can effectively realize the changing waste into resources utilization.Therefore the melting and solidification technology has become one of focus of solid waste research field.
On the other hand, the operating temperature of incineration of refuse flyash melting and solidification is about 1500 ℃, and so high temperature consumes lot of energy, and the operating cost that makes fusing fly ash handle is high, has hindered the further application and the popularization of melting and solidification technology.
Summary of the invention
The object of the present invention is to provide a kind of additive for fusing fly ash that is used for incineration treatment of garbage.This additive has that preparation is simple, raw material sources abundant, and is with low cost.Use the garbage flying ash melt process of this additive, can obviously reduce the fusing fly ash temperature, reduce the volatilization of heavy metal, make the hardness of liquid slag higher simultaneously, quality is fine and close more, reduces the leaching level of heavy metal greatly.
For achieving the above object, garbage flying ash additive for fusing provided by the invention is by weight by the B of 30-50%
2O
3, 25-40% SiO
2, 7-20% CaF
2, 7-20% MgO grind to form 106-256 order mixing.The ZrO that further, in said mixture, can also add 2-5%
2
The present invention adds an amount of additive for fusing fly ash in garbage flying ash, can effectively reduce melt temperature, reduce the volatilization of inorganic salts, the solidification effect of heavy metal in the vitreum of Zeng Jiaing simultaneously, strengthen the various physical properties of liquid slag, the recycling that helps liquid slag more promotes the popularization of fusing fly ash curing technology.

The additive 2g of this example is carried out melt process with the former ash of 60g is mixed after evenly.The flowing temperature of flying dust can be reduced to 1070 ℃, the melting time is 1 hour, and volatility is lower, and the heavy metal leachability of the liquid slag that forms after the shrend cooling is far below hazardous waste judging standard level.
Embodiment 3
Additive for fusing fly ash is formed: 30% B
2O
3, 28% SiO
2, 20% CaF
2, 20% MgO and 2% ZrO
2Mixed 256 orders that grind to form.
Embodiment 4
Additive for fusing fly ash is formed: 40% B
2O
3, 33% SiO
2, 10% CaF
2, 12% MgO and 5%ZrO
2Mixed 256 orders that grind to form.
The present invention has following advantage:
1. the fusing fly ash temperature can be reduced to 1100 ℃;
2. reduce the flying dust time of staying;
3. strengthen the flowability of liquid slag, effectively prevent and treat liquid slag and stop up outlet;
4. increase the hardness of liquid slag, can satisfy the hardness requirement of roadbed material;
5. reduce the volatile quantity of flying dust, alleviate flue gas and handle load.
