Abstract
The invention relates to the field of treatment of dangerous waste, in particular to a comprehensive treatment technique for flying ash of a waste incineration plant. The comprehensive treatment technique for flying ash of the waste incineration plant has the steps that (1) the flying ash is subjected to primary calcination at the temperature of 1240-1400 DEG C, organic pollutants like dioxin in the flying ash are thoroughly decomposed into harmless substances, and the mass of the flying ash is reduced by about 23% through decomposition of CaCO3, CaSO4, aluminum salt, chloride and the like; the flying ash is subjected to secondary calcination, so that glassy cured materials are obtained, wherein mercury, cadmium, lead, arsenic and the like are fixed in the glassy cured materials which meet the demand of GB 16889-2008 of the Standard for Control on the Landfill Site of Municipal Solid Waste; and (2) flue gas generated by incinerating the flying ash at high temperatures is exhausted to a prior flue gas cleaning system of the waste incineration plant. The comprehensive treatment technique for flying ash of the waste incineration plant can effectively avoid secondary pollution of the flying ash for the waste incineration plant, and achieves harmless, smaller-amount and stable treatment of the flying ash.
Description
Technical field
The present invention relates to hazardous waste process field, specially garbage burning factory flying dust comprehensive processing technique.
Background technology
In urbanization process, rubbish as the burden that the product of Urban Metabolism is urban development, many cities in the world
All there is the situation of garbage-surrounded city.Whole world rubbish average annual growth is 8.42%, and China's rubbish rate of increase reaches 10%
Above.The whole world produces 4.9 hundred million tons of rubbish, only China every year and just produces nearly 1.5 hundred million tons of municipal refuses every year.Chinese city is lived
Rubbish accumulation volume of cargo in storage has reached 7,000,000,000 tons.
The processing method of house refuse is just by filling to the mode transition burned at present.Waste incineration method is that a kind of practice is many
The waste disposal method in year.It is little compared with landfill method floor space, and efficiency is high, is the most once being considered the good side of a kind of " decrement is fast "
Method, thoroughly can process rubbish and outward for the energy.
But Refuse Incineration Process will produce substantial amounts of flue gas, the process of gas cleaning created again substantial amounts of flying
Ash.And incineration of refuse flyash is a kind of generally acknowledged hazardous waste, wherein concentrate substantial amounts of heavy metal (such as hydrargyrum, cadmium, lead etc.) and
And further comprises a small amount of severe toxicity two English class material, environment will necessarily be produced secondary pollution, so must be to waste incineration
The flying dust that factory produces carries out harmless treatment.
Summary of the invention
The invention aims to solve the secondary pollution problem of garbage burning factory flying dust, it is achieved garbage burning factory flying dust
Innoxious, minimizing, stabilizing treatment.
Technical scheme is as follows:
(1) under conditions of 1240～1400 DEG C, in high-temperature incinerator, flying dust is carried out first high-temperature calcination, in flying dust
Two English class organic pollutions will thoroughly be decomposed into innocuous substance, CaCO3、CaSO4, aluminium salt and chloride etc. decompose makes flying dust
Quality Down about 23%；Under conditions of 1500～1700 DEG C, in secondary high-temperature incinerator, flying dust is carried out secondary high-temperature
Calcining, obtains glassy state solidfied material, and the pollutant such as hydrargyrum, cadmium, lead, arsenic are fixed in wherein, and glassy state solidfied material meets " life rubbish
Rubbish landfill yard controls standard " GB 16889-2008 requirement, can directly fill.
(2) flue gas that high temperature incineration flying dust produces enters former garbage burning factory flue gas purification system.
Wherein: under conditions of 1300～1350 DEG C, in high-temperature incinerator, flying dust is carried out first high-temperature calcination.
Wherein: two English class organic pollutions in flying dust will thoroughly be decomposed into innocuous substance.
Wherein: CaCO3、CaSO4, aluminium salt and chloride etc. decompose and cause flying dust Quality Down about 23%.
Wherein: CaCO3、CaSO4, aluminium salt in first high-temperature burning process, be decomposed into basic anhydride.
Wherein: under conditions of 1550～1650 DEG C, flying dust is carried out secondary high-temperature calcining.
Wherein: the basic anhydride in flying dust and SiO2Glassy state solidfied material is formed in secondary high-temperature stove.
Wherein: the materials such as hydrargyrum, cadmium, lead, arsenic are fixed in glassy state solidfied material, and glassy state solidfied material meets " life rubbish
Rubbish landfill yard controls standard " GB 16889-2008 requirement, can directly fill.
Wherein: the flue gas that high temperature incineration flying dust produces enters former garbage burning factory flue gas purification system.
Detailed description of the invention
The present invention to be embodied as step as follows:
(1) under conditions of 1240～1400 DEG C, in high-temperature incinerator, flying dust is carried out first high-temperature calcination, in flying dust
Two English class organic pollutions will thoroughly be decomposed into innocuous substance, CaCO3、CaSO4, aluminium salt and chloride etc. decompose makes flying dust
Quality Down about 23%；Under conditions of 1500～1700 DEG C, in secondary high-temperature incinerator, flying dust is carried out secondary high-temperature
