Description
Technical field
The utility model relates to refuse treatment field, relates in particular to a kind of clean energy device for domestic refuse.
Background technology
At present, a large amount of domestic refuses can not get effective processing and utilizing, and severe contamination environment, to governments at all levels, brings very large pressure.At present, the major way of China's treating refuse still be take landfill as main; Yet landfill not only takies a large amount of soils, and foul smell is not easy to control; The toxic and harmfuls such as the methane particularly discharging and dioxin are difficult to collection and treatment; Loading embeading percolation liquid collection processing system implementing load and technical difficulty are large, invest highly, process sewage afterwards and are also difficult to qualified discharge; The domestic refuse stabilization cycle is long, and the rear maintenance phase of closing is long, and environmental risk influence time is long.Over 10 years, waste incineration and generating electricity development is very fast, and the secondary pollution that burning electricity generation produces has become the focus of public attention, opposes that the sound of waste incineration is more and more higher, and mass-sending event happens occasionally, and to social stability, brings labile factor.China's domestic refuse is not classification also, complicated component, the proportion that fruit, greengrocery and food waste and inorganics class rubbish account for is larger, wherein water ratio is higher, and the proportion that combustiblematerials accounts for is less, and calorific value is very low, in stove, temperature is difficult to improve, very difficult that waste incineration is thorough, very easily produce Dioxins, cause the possibility of secondary pollution very large.And the flying dust that rubbish produces when burning, enrichment the most of heavy metal element in rubbish, at flying dust, collect, very easily pollute in storage and transport process.Waste incineration percolate is compared with the percolate of refuse landfill, and metal ion content is high, and change of water quality is large, and toxicity is large, and intractability is larger.
The pyrolytic technique that is called as third generation waste incineration, becomes the heat subject of environmental protection industry research, its advantage recent years: the one, the organism in rubbish can be converted into the shelf characteric sources such as fuel gas, charcoal and carbon black.The 2nd, owing to being that anoxic or anaerobic are decomposed, do not produce Dioxins, amount of nitrogen oxides is few, and free air delivery is few, is conducive to alleviate the secondary pollution to atmospheric environment.The 3rd, the objectionable constituent major parts such as the sulphur in rubbish, heavy metal are fixed in carbon black, are convenient to process.
At present, in the U.S., Europe and Japan, existing a lot of pyrolysis plants put into effect, in China, also have a small amount of pyrolysis oven to come into the market.The most of material handling of these equipment is relatively single, and particularly some gordian techniquies also do not solve.As anaerobic carbonization (indirect heating method) mode, when being heated, pyrolysis reactor (or pyrolysis oven) needs a large amount of external heat, the heat energy of the inflammable gas that organic combustiblematerials produces can only meet 50% of the required heat energy of pyrolysis reactor (or pyrolysis oven), also needs to add 50% auxiliary fuel.Anaerobic carbonization stove is difficult to realize non-stop run, and separate unit stove processing power is little; Objectionable impurities in rubbish, particularly heavy metal major part are all absorbed and fixed in carbide, and therefore, carbide also needs otherwise processed, increase treatment facility and expense.Therefore, this technical equipment is at present at home mainly for the treatment of clinical waste, plastic waste (waste plastic oil-refining), waste rubber and etc.For another example anoxic is burned pyrolysis (snead process) mode, its essence is a kind of modification method of burning.During due to a part of incineration firing, a certain amount of air need to be provided, thereby CO will be produced
2, H
2o, N
2deng gas, be mixed in pyrolysis combustion gas, the calorific value of pyrolysis combustion gas reduced greatly, generally at 3200-4500KJ/m
3left and right, can not oneself burn, need be by other fuel aid burning; Therefore, this gas is generally as off gas treatment, and its treatment facility and operational path and garbage incinerating tail gas are processed unanimous on the whole, and equipment is huge, complexity, and expense is high.Anoxic burning pyrolysis oven is generally vertical, and rubbish needs to carry out processing treatment before pyrolysis, as is processed into fuel stick or fuel brick etc.Otherwise cloth is inhomogeneous in pyrolysis oven, in burning pyrolytic process, just there will be the accident of burning.
