Description
Technical field
The present invention relates to a kind of technology that the incineration of refuse flyash that contains heavy metal and Dioxins can be carried out harmless treatment and realize recycling, especially relate to a kind of method of utilizing incineration of refuse flyash to fire aglite.Belong to Hazardous wastes treatment and disposal technical field.
Background technology
Along with burning disposal the applying of field of treatment of solid waste such as municipal wastes, clinical waste, Hazardous wastes, the incineration of refuse flyash generation increases day by day.Facts have proved, in the waste incineration process, volatilization heavy metal (comprising Hg, Cd, Pb etc.) of attitude and dioxin pollution thing etc. are enriched on the submicron particles such as flying dust easily, cause flying ash to contain the high dioxin pollution thing that leaches toxic heavy metal and higher toxic equivalent, wherein the Dioxins in the flying dust accounts for more than 60% of Dioxins total amount that incinerator produces, and flying ash is regarded as belonging to Hazardous wastes and must special processing be allowed for access ecotope usually.
Incineration of refuse flyash is handled and is mainly comprised following several method at present: cement solidification method, pharmaceutical treatment and pyroprocessing method.
Cement solidification method is with cement and flying dust water uniform mixing, carries out hydration reaction in transmitting tube, sclerosis gradually, thereby objectionable constituent such as sealing heavy metal.The cement solidification expense is low, simple to operate, is particularly suited for containing the more lime-ash of low melting component.But cement solidification method causes the ultimate disposal amount to increase owing to add cement.And its contained salt major part can be by the rainwater stripping after solidifying.And reduce the sexavalent chrome etc. of processing for mercury, lead and needs that the indissoluble characteristic that is difficult to utilize oxyhydroxide is handled and to realize stabilization treatment.Pharmaceutical treatment is to add heavy metal fixing agent and water in ash, is uniformly mixed into insoluble compound, thereby realizes the fixedly purpose of heavy metal.Pharmaceutical treatment has advantages such as treating processes is simple, facility investment is low, final processing capacity is little.But the high-molecular chelating agent price of pharmaceutical treatment is very high, and the most of salt of rainwater meeting stripping, also can produce obnoxious flavour when the pH value is low.
Pyroprocessing comprises melting and solidification method and sintering technology.Fusion is to utilize the combustion heat of fuel and electric heating dual mode, under the situation of high temperature (common more than 1300 ℃), make fusing fly ash, become stable vitreous state slag after the cooling, and destroy organic composition such as Dioxins, with most of heavy metals immobilization in the vitreous state slag.Fusion subtract hold significantly, heavy metal can stripping in the slag, slag can also be as roadbed material.Yet the energy consumption that fusion needs is very high, and processing cost per ton usually is more than 1000 yuan, and implementation acquires a certain degree of difficulty in China.And the heavy metal volatilization is serious under the high temperature, causes the control effect of heavy metal not very good.
The agglomerating temperature is starkly lower than the fusing point of flying dust, the energy consumption that needs is low than scorification, the heavy metal volatile ratio a little less than.Can thoroughly decompose Dioxins, same sintered product can be used as aggregate for building.Therefore, sintering is a kind of more competitive flying dust treatment technology.
Because standard of living and food habits, China's refuse incinerating flyash alkali metal chloride content is very high, and this is unfavorable for high temperature treatment processs such as sintering greatly.Chloride content is high can to promote Dioxins resynthesis in the tail gas on the one hand, causes the control difficulty of Dioxins; Muriate also promotes the vaporization at high temperature of heavy metal simultaneously, influences secondary pollution control effect equally.In addition, sintering process is the sintered products downgrade because water analysis is sent as an envoy to easily, can't realize the resource utilization application.
Summary of the invention
The object of the present invention is to provide a kind of thermal effectiveness that can improve flying ash, reduce the secondary volatilization of heavy metal pollutant in the pyroprocess, improve the incineration of refuse flyash that utilizes of the mechanical property of flying ash calcinate and fire the method for aglite.
A kind of method of utilizing incineration of refuse flyash to fire aglite that the present invention proposes is characterized in that: described method is removed the great amount of soluble villaumite by extraction and separation technology; By the extraction agent consumption of control extraction process and the pH-value of extraction liquid, heavy metal class material is to the migration of extraction liquid phase in the reduction flying dust; By adding binding agent, granulation, sintering process acquisition aglite, this method may further comprise the steps:
(1) at first the high incineration of refuse flyash of chloride content is extracted dechlorination, control the leaching of heavy metal simultaneously by additive;
(2) the flying dust moisture content after the extracting and separating is 30-50%, is transported to granulating and forming equipment by e Foerderanlage, behind the additive of interpolation configuration, utilizes the molding device granulation, and granularity is between 5-20mm;
(3) most of moisture is removed in maintenance in loft drier, moisture＜5%;
(4) particle after the maintenance is carried out sintering, sintering range 900-1150 ℃ in sintering oven;
(5) promptly obtain aglite after the cooling.
In the above-mentioned method of firing aglite, described extraction agent is water or other waste lye, and the extraction agent consumption is a liquid-solid ratio 15～25.
In the above-mentioned method of firing aglite, described extraction liquid pH-value PH＞9.
In the above-mentioned method of firing aglite, described additive is a clay, and addition is 15-30%.
The present invention has overcome the shortcoming that present sintering technology is unsuitable for handling the high flying ash of China's chloride content, solves the problem that muriate causes polluting the control weak effect, and a kind of sintering process in conjunction with the extraction desalination is provided.Also overcome simultaneously owing to material in the sintering process contains moisture ambassador material and split the shortcoming of strength degradation.The present invention is fit to the innoxious and resource treatment technique of Chinese incineration of refuse flyash very much.Simultaneously, the present invention can decompose the dioxin pollution thing that destroys in the raw material, and in sintered products, and the toxicity that satisfies China leaches standard with heavy metals immobilization, and product satisfies the requirement of building light skeletal.Processing cost is lower than 500 yuan/ton.
