Description

The fat of dioxins concentration washes tower in a kind of reduction garbage incinerating tail gas

Technical field

It the utility model is related to garbage incinerating tail gas processing equipment field, and in particular to one kind is reduced in garbage incinerating tail gas The fat of dioxins concentration washes tower.

Background technology

In urbanization process, rubbish is many in the world as the burden that the product of Urban Metabolism was once urban development There was the situation of garbage-surrounded city in city.At present, the processing mode of rubbish is divided into two kinds：Landfill method and burning method, wherein, landfill Method space is big, and the plastic products degraded that the modern life is commonly used is slow, and to environmental pressure weight, and landfill domain is formed Percolate in content of beary metal is big, various bacterium germs grow, for the severe water pollution in landfill region, it is seen that landfill method Processing rubbish is not the meter of sustainable development.

Incineration treatment of garbage method is reacted by appropriate thermal decomposition, burning, melting etc., the oxygen for making rubbish pass through under high temperature Change and carry out volume reduction, turn into the process of residue or molten solids material, heat caused by recovery waste incineration, can reach waste money The purpose in source.Waste incineration is a kind of method of more ancient traditional processing rubbish, after being handled due to rubbish with burning method, Reduction is notable, saves land used, can also eliminate various pathogen, and poisonous and harmful substance is converted into harmless object, therefore rubbish Burning method is as one of main method for the treatment of of urban garbage.

Waste incineration, general in-furnace temperature control is higher than 850 DEG C, and volume ratio can reduce 50-80% originally after burning, point The combustible garbage that class is collected even can reduce 90% after burning disposal, and China's garbage combustion device is entered using foreign countries substantially Mouthful, because external refuse classification processing is ideal, and China does not have to carry out classification processing rubbish substantially, so China's rubbish kind Class is numerous and diverse, integrates combustible and noncombustible matter so that the calorific value of China's rubbish is low, is burnt using external import incinerator Rubbish is burnt, is not easy to reach more than 850 DEG C of incineration temperature, in some instances it may even be possible to which midway is flame-out, on the one hand, so that the waste incineration energy is sharp It is low with being worth, on the other hand it is also easy to produce reluctant a kind of extremely toxic substance dioxin because temperature is not up to standard.It is well known that Dioxin is easily produced in Refuse Incineration Process less than 850 DEG C, its toxicity is equivalent to widely known extremely toxic substance cyanide 130 times, 900 times of arsenic, substantial amounts of zoopery shows, the dioxin of very low concentrations just shows lethal effect to animal Should.Toxicity data and clinical manifestation of some dioxin to human body have been obtained from occupational exposure and industrial accident victim, In the environment containing PCDD or PCDF, can cause skin fully recover from an illness sore, have a headache, become deaf, be melancholy, the disease such as insomnia, and may lead Cause chromosome damage, heart failure, cancer etc..There is result of study to point out, dioxin is also possible to cause that fetal growth is bad, man Sperm count significantly reduces, and the approach that it invades people's human body includes diet, air suction and skin contact.Some experts point out：People Class exposure gives in the environment containing dioxin contamination, may cause male fecundity forfeitures, sterility, Puberty of Female shift to an earlier date, Fetus and infant during lactation illness, immunologic function decline, IQ reduction, mental disease etc..

For the current waste incineration in China because temperature is not up to standard, the dioxins concentration in incineration tail gas does not meet national standard, Post processing is also more difficult, and current exhaust gas processing device effective can't be handled.

Utility model content

The utility model provides a kind of fat for reducing dioxins concentration in garbage incinerating tail gas and washes tower, in waste incineration tail Fat flushing is carried out to garbage incinerating tail gas in gas disposal, can't effective processing rubbish to solve existing exhaust gas processing device The problem of dioxin in rubbish incineration tail gas.

In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is summarized as follows：
