Description

A kind of disposal of human lives's rubbish and the method for recycling
Technical field
The present invention relates to waste resources recycle utilization field, be specially a kind of disposal of human lives's rubbish and the method for recycling.
Background technology
Along with improving constantly of living standards of the people, the kind of rubbish and quantity increasing day by day, the processing mode of rubbish is also constantly being developed, especially the recycling of rubbish is become the development main trend of garbage disposal, but the practicality of methods and the exploitation of the popularization task of top priority especially to garbage disposal.
Realizing the recycling of rubbish first will classify to rubbish, although advocating people in China is at present strengthening the dynamics that abandons refuse classification, but people or seldom or do not have this custom to go to carry out conscious classification by the mark of dustbin in real life, therefore will change this state or very long.There is no good sorting rubbish will be an acid test to refuse disposal system, however more advanced investment larger equipment can not adapt to completely this operating mode, and the certain tool of the investment of equipment is large, therefore the human assistance part that is also absolutely necessary at present.
Many developing countries in the world at present, due to technology and fund reason, traditional landfill, compost, incinerating method are still continued to use in its garbage disposal, these three kinds of methods exist disadvantage many as: 1, landfill method: abandoned and can utilize thing, take up an area can supply greatly fewer and feweri, secondary pollution seriously, to transport landfill administrative expenses large.2, composting process: occupation of land is large, the cycle is long, environmental sanitation is poor, fertilizer efficiency is low, cost is also not little.3, burning method: burnt available resources, burning and produced harmful exhaust and purify high, the lime-ash of cost and also can bring secondary pollution.Above three kinds of methods are all that rubbish is directly processed without preliminary election, and therefore its disadvantage is apparent.
In addition at present both at home and abroad energetically research and development be exactly garbage derivatived fuel (Refuse Derived Fuel) technology, it is that one is first carried out effective pretreatment and processing and forming by house refuse, then the garbage derivatived fuel (being called for short RDF) that is burned utilization as solid fuel, this method is generally applied in garbage disposal.
Summary of the invention
Technical problem solved by the invention is to provide a kind of disposal of human lives's rubbish and the method for recycling, to solve the problem in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions: a kind of disposal of human lives's rubbish and the method for recycling, comprise the following steps:
1), by chain mat machine, bagged garbage is transported to bag-breaking machine place and carries out broken bag processing, screen by spring afterwards, be heavy substance and screenings on the upper light materials of sieve, sieve by screening rubbish, wherein screenings accounts for 25~40% of rubbish gross mass, on sieve, heavy substance accounts for 20~30% of rubbish gross mass, and on sieve, light materials accounts for 25~40% of rubbish gross mass.
2), upper sieve light materials is carried out to second-time breakage, twice pressing dehydration after, gains are carried out to RDF making; First upper sieve heavy substance is divided and elect large metalwork, large fruits and vegetables skin and masonry piece as, residue is transported to magnetic separator and goes out to carry out sorting, the material after magnetic separator carries out RDF making by gains after carrying out second-time breakage, twice pressing dehydration; Screenings is carried out to press dewatering, after being added to water treatment agent, waste liquid carries out press filtration water squeezing, the solid matter obtaining is afforested and flowers and plants for trees by composting, the water up to standard obtaining is normally discharged, solid matter under sieve after press dewatering is carried out to secondary sorting through secondary sorting sieve again, to after the deodorizing of secondary screenings matter, transport outward landfill afterwards, secondary oversize matter is screened through magnetic separator, after metallics recycling, nonmetallic substance are carried out to second-time breakage, twice pressing dehydration, gains are carried out to RDF making.
Described metalwork is sent to salvage station and reclaims, and large fruits and vegetables skin organic matter send fertilizer producing plant to recycle, and masonry piece is processed Hou Song landfill factory landfill through deodorization.
It is 60~90mm that selected compass screen surface sieve mesh is sieved in described spring.
The compass screen surface sieve mesh of described secondary sorting sieve is 20~40 mm.
Described RDF manufacture craft comprises: heating, RDF moulding and cooling forming product.
Compared with public technology, there is following advantage in the present invention:
1, the inventive method is without building fermenting cellar pond and Zymolysis Equipment, and investment like this, occupation of land, cycle all can be improved greatly.Environmentally friendly, be applicable to very much city and build, because investment is relatively few, be more suitable for setting up in Small Urban middle-size and small-size garbage disposal plant.
2, the present invention is by twice pulverizing and twice pressing, to realize the moisture that needs removal in RDF forming process, to realize reduction energy consumption.
3, the inventive method reaches waste reduction 60-70%.
