Description
Technical field
The invention belongs to solid waste disposal field, particularly relate to flue gas of refuse burning control bioxin inhibitor,Control dioxin emission in incineration treatment of garbage flue gas. Being specifically related to a kind of incineration treatment of garbage bioxin that is applicable to suppressesAgent and preparation method thereof.
Background technology
Along with the continuous expansion of city size, the improving constantly of the growing and living standards of the people of urban population,The generation of domestic waste is increasing gradually. As far back as 1996, the municipal refuse amount of clearing of China just reached 100,000,000Ton, and every year with 8% ~ 10% speed increment. The volume of cargo in storage over the years of rubbish reaches more than 60 hundred million tons, and there is more than 200 city in the whole nationBe absorbed among the encirclement of rubbish, rubbish is stored up the land area of occupying and is reached more than 500,000,000 square metre. Garbage disposal has become restrictionThe major issue of Chinese city environment.
Burning disposal is recovery section energy when fast processing discarded object on a large scale, can make house refuse subtract appearance80%～95%, the final disposal amount of rubbish is dropped to minimum, and can utilize the harmful components in pyrolytic rubbish, kill rubbishPathogen in rubbish and parasitic ovum; The heat energy producing when incineration firing also can fully reclaim, for supplying heat and generating power. With otherProcessing method is compared, and burning method not only meets " three change " principle of garbage disposal, and it is little to have floor space, stable,The multiple advantages such as the processing time is short, have become the preferred option of urban garbage disposal in many countries and regions.
Due to its land resource scarcity, waste incineration is very common in some developed countries, as Japan has built up more than 6000Seat incinerator, occupies the first place of world's incinerator quantity. Denmark and Sweden utilize to burn away the refuse to produce electricityThe pioneer of power, in existing century more than one of application, 2005, domestic 4.8% electric power was supplied in the incineration of garbage of Denmark, and13.7% heating consumption. Some other country of Europe especially burns and processes city as Holland, Germany and French extremely dependenceRubbish. According to China's " urban construction statistics annual report ", the quantity of China's garbage burning factory and average treatment scale increase year by year, rubbishThe ratio of rubbish treatment facility in installation for rubbish processing to be harmless also increasing, and these all illustrate that incineration technology is at rubbish place of ChinaComponent shared in reason is more and more heavier. Prediction, coming 10 years, Chinese incineration treatment of garbage total amount ratio is by by present 2%～3%Rise to 10%～20%.
But, due to China resident's habits and customs and rubbish mixed collection pattern, cause the house refuse of China moistureRate is high and contain a large amount of plastics, metal species material, for the generation of bioxin provides material base. Add incineratorIgnition temperature low (850 DEG C are following), material is the time of staying short (being generally 1～3 second) at high temperature, and discarded object is difficult to divide completelySeparate, may produce imperfect combustion product and some pernicious gas as sour gas with bioxin etc. cause atmosphere pollution; Lime-ashIn flying dust in also abdominal muscle a large amount of bioxin, belong to danger wastes, if transport, storage, treatment and disposal are improper, willHuman health, ecological environment are formed to serious harm, and therefore, it is that puzzlement rubbish burns that tail gas and flying dust bioxin are processed alwaysBurn the principal element of factory's construction. The worry of the environmental protection aspect of people to traditional life incinerator, the life of China's Program ConstructionThe construction of garbage burning factory alive has run into sizable resistance, and the garbage burning factory of a lot of urban plannings slowly fails to go into operation to buildIf.
Summary of the invention
The object of the present invention is to provide a kind of flue gas of refuse burning control bioxin inhibitor that is applicable to, solve rubbishBurn the Shi dioxin emission problems such as the serious environmental pollution that causes that exceed standard, the flue gas of waste incineration can up to standardly be arrangedPut, reduce the difficulty of post-processed, the feature producing according to dioxin-like compound, development can suppress bioxin from source and closeThe additive becoming, thus reach the object that suppresses dioxin emission.
