Municipal solid waste passes through a material homogenizing machine and is screened by a macroporous rotary screen, wherein inorganic products are artificially sorted from oversize products and are land-filled, organic matters from oversize products are crushed and mixed with raw materials with high calorific value uniformly to prepare RDF (Refuse Derived Fuel) finished products; undersize products are artificially sorted to obtain inert materials and recyclable materials after bag breaking, then the residuals are screened by a mesoporous rotary screen, the undersize products are de-ironed and further screened by a relaxation screen and are land-filled, the oversize products pass through a bailing machine to remove inert materials and sand, then the remnant oversize products enter a crushing and slurrying system, particles, which are not prepared into slurry, are RDF raw materials, the prepared slurry enters a regulating tank and is additionally provided with organic matters, and then the mixture is fermented in a fermentation tank to produce marsh gas; biogas residue is subjected to dehydration, granulation and drying to obtain organic fertilizer; the oversize products screened by the mesoporous rotary screen are deironed and windowed by a winnowing machine, heavy materials are artificially sorted into organic bulks, recycled plastics, inert materials and RDF raw materials, light materials after windowing are artificially sorted into recycled plastics and RDF raw materials, and the recycled plastics are packed by a packer and recycled.
Description
One, technical field:
Belong to technology of garbage disposal field, relate to municipal solid wastes comprehensive processing technique, particularly anaerobic fermentation production technology.
Two, background technology:
Along with the raising of socioeconomic development and living standards of the people, the discharge capacity of solid waste increases sharply, according to estimates, and about 10,000,000,000 tons of the annual newly-increased solid waste in the whole world, 2 tons per capita.Today, solid waste problem becomes the focus point of people's sight with its " the most seldom to dispose ", " tool comprehensive ", " being paid attention to the latest ", " closeness to life ".Disposal of refuse refuse mainly contains three kinds of modes at present: landfill, burning, compost, mechanical sorting.
The feature of Landfill is simple to operate, can process the rubbish of all kinds.But floor space is large, there is serious secondary pollution simultaneously.
Rubbish is carried out to burning disposal, and to subtract appearance, decrement and innoxious degree all very high, and the heat that burning process produces is used for generating and can realizes the energy of rubbish, is a kind of waste disposal method preferably.But have smoke pollution problem to burning the improper meeting of condition control, and equipment investment is huge.Solve preferably smoke pollution problem, also corresponding increase of investment by improving the means such as CIU technique and the processing of strengthening flue gas at present abroad.
Composting technology can not be processed not putrescible organic matter and inorganic matter, subtracts appearance, decrement and innoxious degree low.Therefore only rely on compost treatment still can not thoroughly solve garbage problem.
Screening rubbish, selection by winnowing, wet concentration are realized to refuse classification, facts have proved that this pure mechanical sorting method can not be thoroughly clean by refuse classification, finally still have a large amount of rubbish will remove landfill.
Three, summary of the invention:
The object of the invention is the new technology that openly a kind of municipal solid wastes anaerobic fermentation is produced.
It is as described below that the present invention will address the above problem adopted technical scheme:
First, the method combining by mechanization automatic sorting and sorting is manually classified to rubbish, and then sorted rubbish being neutralized to utilization change rubbish is treasured:
1, valuable material is reclaimed: as iron, glass, pop can, plastics etc. carry out recycling as material;
2, to perishable organic matter: produce biogas as rotten dish, ight soil, changing food waste, mud etc. carry out anaerobic fermentation, produce clean energy resource;
3, to not perishable organic matter: as the foreign material such as wood fragments head, duds thing, footwear add oxidizer after powdering by pulverizing, then by stirring, produce graininess combustibles;
4, granularity is less than to 25 millimeters of following organic matters and inorganic matter and can be considered that organoclay carries out landfill.
First this technique be that rubbish is put into material homogenizer, after homocline, by macropore rotary screen, rubbish is sieved: the oversize after screening carries out artificial separation, the inorganic matter sub-electing is carried out to landfill, the organic matter sub-electing is carried out fragmentation and adds the raw material that calorific value is high, by producing RDF finished product after stirring and evenly mixing; Screenings after screening is through the laggard row manual sorting of broken bag, detecting inert material and the Recyclable residue after as glass sieves through mesopore rotary screen again, screenings enters the further screening of relaxation sieve after deironing, screenings is considered as Nutrition Soil landfill, oversize enters after bailing machine removes inert material and desanding and enters pulverizing pulping system, the particle of not making slurry is RDF raw material, the slurries of making enter regulating tank and add and enter fermentation tank after organic matter and ferment and manufacture biogas, and the natural pond slag after fermentation is made fertilizer after dehydration, granulation, oven dry; To the deironing of mesopore rotary screen oversize laggard enter winnowing machine, the heavy material that selection by winnowing goes out goes out bulk organic matter, recyclable plastics, inert material, RDF raw material through artificial separation again, the light material that selection by winnowing goes out is through manually sub-electing RDF raw material and recyclable plastics again.After being packed by baling press, recycles recycled plastic.
The invention has the beneficial effects as follows that domestic waste, sewage plant sludge, changing food waste, human and animal excreta are sent into anaerobic fermentation tank after by different pretreatment approach carries out anaerobic fermentation, for the garbage reclamation of recoverable, the inert substances such as sandstone are carried out to sanitary landfills.Have that treatment effeciency is high, profitable, classification treatment effect is good, process totally feature thoroughly.
