Description

The method of domestic waste incineration and processing house refuse
Technical field
The present invention relates to domestic waste incineration, particularly a kind of domestic waste incineration and the method for handling house refuse of controlling the bioxin discharging.
Background technology
Present innoxious, the minimizing of domestic waste, the recycling treatment focus that become the country and the common people to pay close attention to.The maximum mode of domestic rubbish disposal minimizing at present is to burn, but loads in mixture shape owing to China's house refuse is, and composition is complicated in the house refuse, and the flue gas that burns the back generation can cause serious secondary pollution as not adding effective control.Endanger maximum Shi bioxin in the flue gas at present.Bioxin (Dioxin) full name is: Duo chlorodiphenyl Bing bioxin polychlorinated dibenzo-p-dioxin (being called for short PCDDs) and polychlorinated dibenzo polychlorinated dibenzofuran (being called for short PCDFs) are the extremely strong special organic compounds of a kind of toxicity.Bioxin is the representative of environment incretion interferent, and the endocrine of their interfere bodies produces health effect widely; Bioxin has tangible immunotoxicity, can cause animal thymus atrophy, cellular immunity and humoral immune function reduction etc.; Bioxin can also cause skin lesion, the generation that can be observed skin transition angling, pigmentation and chloracne etc. the animal used as test that exposes and crowd; Bioxin 2,3,7,8-TCDD has extremely strong carcinogenic to animal.
Dioxin has two characteristics, the stability of first molecular structure, and , dioxin molecular structure quite stable below 705 ℃ the time is higher than this temperature and promptly begins to decompose; It two is to be prone to synthetic property, He Cheng dioxin very easily once more when containing compound such as chlorobenzene, chlorophenol and temperature at 300-500 ℃ in the flue gas.
The consumer waste incineration generation of dioxin mainly is derived from three links at present: before burning, in the burning, after the burning.
Before the burning: itself contain micro-De bioxin in the house refuse, when high-temp combustion because bioxin has heat endurance, although big portion is able to decompose; When burning condition is insufficient; Can not fully decompose, still can some after burning, emit, get into atmosphere with flue gas.
In the burning: in combustion process, generate bioxin by chloride precursor; Precursor comprises polyvinyl chloride, chlorobenzene, pentachlorophenol etc.; The precursor molecule can generate bioxin through processes such as rearrangement, free radical condensation, dechlorination or other molecular reactions in burning; Meeting is insufficient because of burning, temperature is low, short can not the decomposition fully of time, thereby gets into atmosphere with flue gas.
Burn the back: synthetic again in handling, discharge at flue gas; Decomposed dioxin and produce in combustion process some Yu the ring-type predecessor (chlorination aromatic hydrocarbon) of dioxin structural similarity; When flue gas slowly is cooled to 300 ℃-500 ℃; Heterogeneous catalytic reaction He Cheng dioxin intermediate product Huo dioxin can take place on solid flying dust surface; Perhaps with non-volatile metal and its esters multiple reaction takes place on the flying dust surface, generate the surface-active chloride, the organic reaction of the multiple complicacy of process generates once more at last and is adsorbed on the lip-deep bioxin of fly ash granule again.
Chinese patent document CN201184597Y discloses a kind of waste incineration treatment apparatus of realizing dioxin and dust zero discharge; This device comprises rubbish warehouse, incinerator, waste heat boiler; The exhaust-heat boiler flue gas outlet is directly heated the rubbish in the rubbish warehouse through air-introduced machine, flue gas distributor box, electrically operated valve, base plate air admission hole; Make its fermentation, dehydration: flue gas is when heating rubbish, and rubbish plays a role in filtering to flue gas again; Loop exit links to each other with secondary air system in loop exit and the warehouse blast pipe in the top of rubbish warehouse is provided with the warehouse flue gas, warehouse flue gas; The warehouse blast pipe is connected with deduster through stalk ash, pulverized limestone entrance, above deduster, is provided with clean gas outlet; This utility model need not be carried out preliminary treatment to municipal refuse, and the entire process process is gone round and begun again and circulated in internal system.The document has also been described municipal refuse and in incinerator, has been burned the flue gas that produces; Flue gas through waste heat boiler heat absorption back discharge; Under the traction of air-introduced machine, directly send in the flue gas distributor box that is arranged on below the rubbish warehouse through flue; The flue gas distributor box is provided with several electrically operated valves and cuts off with the flue gas of rubbish warehouse floor below respectively and is connected; Electrically operated valve is electrically connected through lead and automatic control unit; Automatic control unit is electrically connected through power switch and power supply, and electrically operated valve is the program rhythmical folding under the control of automatic control unit that configures according to the people, and flue gas is evenly heated rubbish through the zones of different that the base plate air admission hole on the warehouse base plate is blown in the rubbish warehouse according to certain rules; The flue gas that incineration firing produces is when heating rubbish, and rubbish plays a role in filtering to flue gas again, and harmful substances such as the bioxin that flue gas contains, dust, heavy metal are fallen by rubbish filtering.
This shows that this incinerator burns the flue gas that produces and only only with regard to being transferred back the rubbish warehouse again the rubbish in the rubbish warehouse heated without other any processing through waste heat boiler heat absorption back.At first rubbish itself does not have filtering function, does not have the effect of filtering bioxin, and like untimely processing, going round and beginning again so only can make internal system De bioxin content increasingly high in the internal system circulation, forms vicious circle; Dust in flue gas that next is filtered and heavy metal time have been grown not only and can stop up the base plate air admission hole; And dust in flue gas and heavy metal also can be along with rubbish is admitted to incinerator once more; So only can facilitate the generation of bioxin, produce more substantial bioxin.
