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 easily 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 decomposed, when burning condition is insufficient, can not fully decompose, still can some after burning, emit, enter 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 by 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 enters 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, with non-volatile metal and its esters multiple reaction takes place on the flying dust surface perhaps, generate the surface-active chloride, the organic reaction of the multiple complexity of process generates once more at last and is adsorbed on the lip-deep bioxin of fly ash granule again.
Chinese patent literature 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 by 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 by stalk ash, pulverized limestone entrance, is provided with clean gas outlet above deduster; 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 burned the flue gas that produces in incinerator, 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 by 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 by lead and automatic control unit, automatic control unit is electrically connected by power switch and power supply, 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 by 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 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 as untimely processing, going round and beginning again so only can make internal system De bioxin content more and more higher 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.
