Description
Technical field
Viewpoint from environmental pollution, the present invention relates to generally to burn ashes (flying dust, main ash) and the waste gas harmless treatment that produces, and will burn ashes and spread with decomposition processing method and equipment thereof the safe stable form of innoxious one-tenth, that can be used as renewable resource utilization.
Background technology
In the past, rubbish was by burying or burning disposal, but over past ten years, owing to produce in a large number, the expansions of a large amount of consumption cause rubbish to increase, the problem of thing followed garbage disposal becomes the socialization problem.Therefore, mainly by autonomous body's burning disposal, present 70% rubbish is through burning disposal in the processing of rubbish.
But, along with the increase of the burning disposal of rubbish, the multiple problem of environmental pollutions such as heavy metal problem that contain in the generation problem of bioxin or the waste incineration ashes take place.
The burning ashes of discharging from incinerator in the past generally by burying processing, much do not burn composition but burn to contain in the ashes.This does not burn a large amount of carbon that burn that contain in the composition and hydrocarbon etc. is not the precursor that generates harmful substance.In addition, contain a large amount of organochlorine compounds, heavy metal class with dioxins materials in the flying dust that the precipitron of burning facility is collected.
The precursor of these harmful substances, organochlorine compound He bioxin are to produce owing to rubbish not exclusively burns.Therefore, if rubbish is burned fully, then can not produce harmful substance.But burning facility does not in the past possess the ability that rubbish is burned fully mostly, is that the burning ashes that contain a large amount of harmful substance Huo dioxins materials are directly buried processing at present.

Description of drawings
Fig. 1 is the flow chart of atom diffusion innoxious processing method with decomposition of burning ashes of the present invention.
The specific embodiment
Below, use marginal data one embodiment of the present of invention.Fig. 1 is the flow chart that the present invention passes through to burn atom diffusion innoxious processing method with decomposition of ashes.
The processing method of burning ashes of the present invention is that the whole burning ashes (being called former ash down) that use main ash, flying dust or burning back generations such as their combination ash (incineration residue), other industries discarded object are as raw material (former ash reclaims).This former ash generally contains nearly 40% moisture, and in order to handle easily in subsequent step, using hot blast to make the interior temperature of stove is 500～700 ℃, is preferably 600 ℃ and carries out drying processing (dehydrating step).
Because this drying steps carries out in the presence of air, therefore the not incinerated matter that contains in the former ash is burned fully.
In addition, for the gasification and being released in the atmosphere when the heated-air drying of the harmful substance that prevents to contain in the former ash, the waste gas that aforementioned drying steps produces, the smoke evacuation treatment step of the harmful substance that in processing waste gas such as use catalyst, contains, discharge into the atmosphere (smoke evacuation treatment step).
Therefore, this processing of discharging fume also can be handled the smoke evacuation that reduction reaction treatment step described later, stabilization processes step produce.
Then, the metal species material that contains in the former ash with the drying processing is absorbed with the magnetite equimagnetic and is gone, and with screening category of glass material and coarse impurities such as vibratory sieves.In addition, the category of glass material of screening by the trickle pulverizing of glass pulverizer after, mix (crushing and screening step) with former ash by sieve.
To crush and screen the former ash that step has been removed metal species material and impurity aforementioned,, and use gradation such as rotoclone collector with the pulverizer pulverization process.Particle more than the specified particle diameter in the former ash behind the gradation is put back in the pulverizer again, and the particle diameter that makes former ash is less than specific particle diameter (pulverization process step).
The various metal species materials that contain in this former ash, for example iron, lead, copper, cadmium, mercury etc., these metal species materials utilize in follow-up reduction step as catalyst.In general the metallic catalyst surface area is little, and its catalytic activity as catalyst is also little, therefore former ash must be pulverized and handle, and increases the surface area of micropowder, and activity of such catalysts is increased.Therefore, so-called specific particle diameter, influential to activity of follow-up reduction treatment step etc., so be preferably 50～200 orders, be more preferred from 100～150 orders.
In addition, lack atom in order to make in the metal lattice that contains in micronized pulverization process in former ash, the present invention uses heat and the impulsive force and the catalyst of minimum.So, the pulverization process of this pulverization process step, inertia force is more than the 3G, preferably carries out with the impact condition of 5G.At this, also without particular limitation to the pulverization process machine that the pulverization process step is used, hammer-mill is for example arranged.
In the process former ash of aforementioned pulverization process step, add catalyst and additives (inorganic substances etc.) such as Pt, and put in the reduction reaction furnace, former ash is heated to 600 ℃, carry out 40 minutes reduction reaction (reduction reaction step).
Regulate the low oxygen concentration of this reduction reaction furnace by importing inert gases such as nitrogen.In addition, contain the oxide of metal and nonmetalloid in the former ash, these materials also can cause noxious material to produce as catalyst sometimes.Therefore, in order to suppress the generation that these toxicants particularly are the harmful substance (for example dioxin) that generates of medium with oxygen, the oxygen concentration in this stove is preferably below 6%.In order more effectively to prevent the generation of harmful substance, oxygen concentration is more preferably below 3%.
At this, can be various forms such as gas, liquid, solid as the material of catalyst.
In general the ， dioxins materials can't decompose at the incineration temperature below 950 ℃.But, using method of the present invention, former ash is in the micronizing of aforementioned pulverization process step, and the disappearance of the metallic atom in the metal lattice, and is activated by the diffusion phenomena of atom, therefore can decompose under 500～600 ℃ low temperature.
In addition, when sneaking into calcium oxide therein, can begin to decompose bioxin, generate calcium chloride at low temperature more.
Therefore the ， dioxins materials with the space of the low oxygen concentration atmosphere of atmospheric isolation, by keeping certain temperature and certain hour,,, and be decomposed by catalyst and additive (inorganic substances) dechlorination/hydrogenation with the diffusion phenomena activation.
Then, through the former ash after the reduction reaction step, under described low oxygen concentration atmosphere, regulating the interior temperature of stove is 300～600 ℃, more preferably is adjusted to 400～500 ℃, carries out 20～30 minutes heat treated (stabilization processes step).
In this step, utilize the diffusion phenomena of atom, the former ash of the mixture of the multiple metal that contains heavy metal is decomposed effectively mutually, utilize heavy metal salt, metal oxide and metal monomer to be catalyst, dissociating metals salt makes its crystallization and makes it stable.
At this, diffusion is meant moving of the middle atom of solid metal (crystallization), and just atom freely moves back and forth among crystallization.
Under the solid state of one of existence form of material, most material forms crystallization, and in this crystallization, most atoms are lattice by the neat assortment of three-dimensional.In the present invention, make metallic atom disappearance in the lattice owing to the inertia force that gives 5G in the pulverization process step impacts, so produce hole or distortion in the metal lattice, metal becomes labile state.
Therefore, under the heat energy effect, the warm-up movement of atom increases, atom in the crystallization freely move back and forth (disperse state), new atom lacks and the distortion (dehalogenation) of elimination lattice in the lattice, perhaps, easily the hole in crystallization holds atom and eliminates the distortion of lattice, and metal is converted to stable compound (stabilisation) simultaneously.
Moreover metal becomes stable compound in this stabilization step, according to the kind of metal, obtains the various forms of oxide, hydroxide, sulfate, sulfide, phosphate, phosphide or the like.For example, the metal beyond alkali metal and the alkaline earth metal stably becomes water-fast hydroxide mostly.In addition, Pb etc. can become hydroxide [Pb (OH) with being stabilized
2], but because this hydroxide under strong acid condition, have water-soluble, so stabilize to sulfide.In addition, As and P and CaO reaction, thus make it stable.
The density height of these metallic elements mainly belongs to the metal of transition metal and its ion.Element in the former ash component, content is fewer in normal soil.But, also contain the trace element that can not lack in the former ash component as the plant growth.
In addition, not that the nonmetal trace element that is harmful to designated substance also relates to pollution problem sometimes.

In addition, the basicity CaO/SiO of former ash
2Height has the slowly character of crystallisation by coolingization, and cooling then becomes the nature of glass rapidly,, is insoluble in the material of water that is, and generates stable and safe material.
Moreover, in this stabilization step,, can add the additive of mineral-type for the character that changes compound is insoluble petal.For example, the additive of calcium system, phosphorus system is not owing to there is toxicity to can be used as main additive.Moreover using calcium is the occasion of additive, and the chlorine in the former ash is fixed to calcium chloride.This calcium chloride is that nuisanceless material can not pollute.
Then, the product (hereinafter referred to as the former ash after handling) that uses method of the present invention to obtain from former ash is described.In general, because former grey water content height is the mixture of organic principle and heavy metal class material, when in the cement of water cure, using, be difficult to solidify.
For innoxious metal, and the sclerosis that promotes organic compound with this curing stopping cause, the former ash after the processing of the present invention, the diffusion of the atom by corpusculed is decomposed, and the cooperative effect of catalytic reaction and reduction reaction is removed hindering factor.
In general, cement and water react, and separate out the crystallization of hydrate, because its condensation cure, this crystal of hydrate is stable at normal temperature.Constitute the element of cement, maximum compositions is a calcium, be oxygen, silicon, aluminium, iron, sulphur, magnesium, sodium etc. secondly, but chemical composition is with CaO, SiO

With cement relatively, the advantage of the former ash after the processing is can be because of with steam or carbon dioxide gas precursor reactant and not fixed by weathering.
And the former ash after the processing contains the aluminium oxide of big quantitative response fierceness or magnesium, calcium component, because its amount is more than the content in the cement composition, therefore has the feature that reaction speed is fast and the coefficient of expansion is high.
In addition, in general cement is cured, and its structure destroys easily, the Ca in sulfate and the concrete (OH)
