Description
Technical field:
The present invention relates to a kind of pernicious gas dynamic purification reactor, particularly a kind of incinerator is removed the device of bioxin pernicious gas.
Background technology:
Dioxin (Dioxin), claim again dioxa glutinous rehmannia, 2, 3, 7, 8-tetrachloro dibenzo is to dioxin 2, 3, 7, 8-Tetrachlorodibenzo chemical formula: C12H4C1402, it is a kind of colorless and odorless, the liposoluble substance that toxicity is serious, dioxin is actually abbreviation of dioxin (Dioxins), what it referred to is not a kind of one matter, but structure and character very similar two large class organic compounds that comprise numerous congeners or isomers all, full name is respectively that polychlorinated dibenzo-2 is disliked English polychlorinated dibenzo-p-dioxin (being called for short PCDDs) and polychlorinated dibenzo polychlorinated dibenzofuran (being called for short PCDFs) connects 2 phenyl ring that replaced by chlorine atom by 2 oxygen atoms, for polychlorinated dibenzo (PCDFs) connects 2 phenyl ring that replaced by chlorine atom by 1 oxygen atom.On each phenyl ring, can replace 1～4 chlorine atom, thereby form numerous isomers, wherein PCDDs has 75 kinds of isomers, and PCDFs has 135 kinds of isomers.So dioxin comprises 210 kinds of compounds, this class material is highly stable, and fusing point is higher, and the utmost point is insoluble in water, can be dissolved in majority of organic solvent, is the liposoluble substance of colorless and odorless, so be very easy to accumulation in vivo.Natural microorganism and hydrolysis are less on the molecular structure impact of dioxin, and therefore, the dioxin in environment is difficult to natural degradation and eliminates.It comprises 210 kinds of compounds.Its toxicity is very large, is 130 times of cyanide, 900 times of arsenic, has the title of " poison in century ".IARC has been classified as mankind's one-level carcinogenic substance.Environment specialist claims, " dioxin " is often present in atmosphere, soil and water with small particle, and main pollution sources are chemical industry metallurgical industry, waste incineration, papermaking and produce agrochemical industry.The poly-bag that daily life is used, the things such as PVC (polyvinyl chloride) flexible glue all contain chlorine, just can discharge dioxin while burning these article, are suspended in air.
The toxicity of dioxin because of the position of substitution of chlorine atom different variant, therefore the content with them in Environmental Health Hazard degree assessment is multiplied by equivalent toxic factor (toxic equivalency factors, TEFs) obtain equivalent toxicity amount (toxic equivalent, TEQ).In dioxin with 2,3,7,8-tetrachloro-dibenzo-p-dioxin (2,3,7,8-tetrachlorodibenzo-p-dioxin, 2,3,7, toxicity 8-TCDD) is the strongest, studies also maximum.
Dioxin in atmospheric environment 90% derives from city and industrial refuse and incineration.The timber of doped fuel, coal, preservative treatment and oil product, various discarded object particularly Biohazard Waste easily produce dioxin during lower than 300-400 ℃ in ignition temperature.The processes such as the production link of igelite, paper, chlorine and some agricultural chemicals, smelting iron and steel, the activation of catalyst high temperature chlorine all can discharge dioxin in environment.Dioxin is also present in some Pesticidal products as pentachlorophenol, 2,4, in 5-T etc. as impurity.In urban industry Refuse Incineration Process, the formation mechanism of dioxin is still among research.
Think at present the three kinds of approach that mainly contain: 1. in to the burning process of the plastic containing chlorines such as vinyl chloride, incineration temperature is lower than 800 ℃, and chloride rubbish imperfect combustion, very easily generates dioxin.After burning, form chlorobenzene, the latter becomes the synthetic precursor of dioxin; 2. other are chloride, carbonaceous material generates dioxin without chlorobenzene as the catalytic action of the metal ions such as process copper, cobalt such as paper, woodwork, swill.3. in manufacture, comprise that the chemical substance of agricultural chemicals, especially chlorine are chemical substance, the process that resembles the products such as Insecticides (tech) & Herbicides (tech), timber preservative, defoliant (U.S. army is for the Vietnam War), Polychlorinated biphenyls derives from.
Mechanism of carcinogenesis
Dioxin be the assorted aromatic hydrocarbons toxic chemical of many chloro three epoxies be commonly called as that (original structure is 1,4-dioxane hexadiene), in fact comprised the most dangerous environmental contaminants of two classes in the world today---many chloros dibenzo dioxin (Poly-o-chiorinated dibenzodioxin, PCDD) and many chloros dibenzofurans (Poly-o-chlorinated dibenzofuran, PCDF).Because each chlorine atom can occupy any one in eight the position of substitution in its chemical constitution, the PCDD and the PCDF that therefore contain some chlorine atom can have several isomers.PCDD amounts to theoretically can have 75 isomers, PCDF to have 135 isomers.Study verifiedly, the toxicity of this two compounds depends on replacement number and the position of substitution of chlorine atom significantly, and 2, the isomers toxicity of 3,7,8 the position of substitution is the highest; 2, the LD50 value of the cavy oral liquid of 3,7,8 one T4CDF is respectively 0.6-2ug/kg and 5-10ug/kg, is the highest compound of toxicity so far, and toxicity is 130 times of sodium fluoride, 900 times of arsenic, is called as " poison in poison ".The World Health Organization is classified as the toxic chemical suitable with pesticide DDT toxicity, environmental protection organization is regarded as one of environmentally hazardous formidable enemy especially, thereby caused various countries scientists' extensive concern, to its analytical method, toxicity, environmental behaviour and health effect conduct in-depth research.Animal data shows, TCDD is easily by gastrointestinal absorption, be distributed in each position in animal body, because dioxin has stronger affinity with fat, dioxin is generally accumulated after entering animal body in liver, fat, skin or muscle, or enter rich fatty livestock product, as milk and yolk.When people has eaten by the fowl of dioxin contamination poultry meat, egg, milk and manufactured goods thereof, as butter, cheese, sausage, ham etc., dioxin has also just entered human body, accumulates, and may excrete by digestive system hardly in the same fat deposit at human body or internal organs.Continuous Contact TCDD, body accumulation can reach a maintenance level.Dioxin has strong carcinogenic and teratogenesis, zoopery shows, first dioxin brings out liver and respiratory system cancer, secondly also cause disease of immune system, increase the infected chance of body, belong to the most dangerous environmental contaminants, IARC classifies dioxin as mankind's one-level carcinogenic substance.
From the burning to rubbish.Incineration temperature is lower than 800 ℃, and the chloride rubbish imperfect combustion of plastics and so on, very easily generates dioxin.Dioxin is diffused in atmosphere with smog, and what by breathing, enter human body is small part, is to be more absorbed by the body by food.Take fish as example, and dioxin particle is fallen rivers and lakes He Hai with rain.By the planktonic organism in water, eaten, planktonic organism is eaten up by small fish, small fish is eaten up by large fish again, slowly accumulation is concentrated in food chain whole process for dioxin, Deng gathering concentration in large fish body, be in water more than 3000 times, and will have assembled more dioxin in mankind's body on food chain peak.Once fearful is to take in dioxin to be just difficult to excrete, and runs up to a certain degree, it just causes a series of serious diseases.
Harm
Dioxin is poisonous to human body, and the poisoning rear non-specific symptom that first occurs, as there is excitement at the positions such as eyes, nose and throat, dizziness, sense of discomfort and vomiting.Then in exposed skin Shang，Ru face, neck occurs red and swollen, and after several weeks, occurring skin damage symptoms such as " chloracnes " has the tumour of 1 millimeter to 1 centimetre, and there are dark acne centre, and periphery skin has pigmentation, sometimes with hair hyperplasia.Sustainable several months of chloracne and even several years.
In addition, dioxin acute poisoning symptom also has liver swollen, and hepatic tissue is impaired, and liver function changes, and blood fat and cholesterol increase, indigestion, diarrhoea, vomiting etc.Spirit-neurological symptom is mainly insomnia, and headache is had the fidgets, emotional, eyesight and dysacousis and weakness of limbs, and sensory deprivation, personality changes, demoralized etc.The most impressively the carcinogenicity of dioxin and teratogenesis.Zoopery has confirmed the carcinogenicity of dioxin.Observation shows, the workman of Long Term Contact dioxin and Vietnam veteran (having contacted the defoliant that contains dioxin), and its cancer morbidity obviously improves.International organization is reclassified as mankind's one-level carcinogenic substance dioxin from suspect carcinogen.
