Description
Technical field
Patent of the present invention is related in field of Environment Protection the pre-treatment classification sorting recovery method about solid waste.This law carries
Supply a kind of hygroscopic water to pick and the equipment of slurrying, be mainly used in reclaiming in rubbish, kitchen or kitchen waste containing can directly reclaim
And the materials such as the metal, glass, plastics of recycling factory are delivered to, while slurry is made in case biochemical process in the leftover materials after sorting
Or the further recycling of thermalization method, reach discarded object complete resource and the almost purpose of zero-emission.
Background technology
The sorting classification of rubbish, the operation that must be carried out for garbage as resource.The garbage sorting classification of urban community at present
Frequently with two kinds of modes：Source sorting (i.e. the every household of regulation generation rubbish carries out respective sorting), and center sorting is (i.e.
Concentration is sorted using garbage sorting factory).The garbage sorting classification of traditional center sorting factory, especially current flourishing state
The popular technology used of family, it is the method for distributing of universe formula often.This kind of method uses grain sorting (example typically after garbage bag breaking
Such as with drum screen or other sieve method equipment), or particle is chopped into more uniform size, then carry out pneumatic separating (Air
Classification) with separated heavy class material (generally inorganic matter) and light class material (generally organic matter).Or utilize it
His proportion and the different principle of hardness, with inertia method of distributing, such as ballistic（Ballistic）Or flip-over type method, with separation
The material of different specific weight.Then weight class material is subjected to magnetic method (Magnetic Separation) and eddy-current method (Eddy again
Current Separation) to separate the metals such as iron and aluminium.Such heavy class material also can carry out light point-score again to separate glass
Glass.Certainly wind-force and inertia conjunction And " knife point-score " (Air Knife) can also be designed to separate the material of different specific weight.It is and light
Class material, such as the organic matter such as plastics, stationery, wooden class and swill, then because proportion is similar (typically between 0.8 to 1.2)
More difficult separation.Such light material is often crushed and the popular term of the industry is made and claims RDF by many reclaims factories again
(Refuse Derived Fuel).Such RDF can do fuel applications, or deliver to incinerator to reclaim the energy.RDF also can be through
Compost is made by biochemical process (biochemical process), or applies inhomogeneous thermochemical method, such as wet oxidation recovery chemicals
And the energy, or reclaim flammable material with technologies such as pyrolysismethod, evaporating methods and carry out the energy or material recycle.A series of above-mentioned universes
Sorting Technique is often used in western countries' rubbish center sorting factory of prosperity.Because the moisture content of west rubbish is typically relatively low, about
Between 25 to 35%, also containing less wet viscous material, Gu Lajifenjianchang is easier to use universe Sorting Technique.
Current universe Sorting Technique still suffers from some defects, such as organic matter (such as plastics, yarn fabric, swill, paper
Class, wooden class etc.) between because proportion and many physical property are close to (typically between 0.8 to 1.2, non-conductive) and difficult conventional art point
Pick.And inorganic weight class (general proportion>2), the iron in removing heavy metals, outside aluminium, the separation of unclassified stores more difficult economical and effective.
Especially oriental rubbish, or the discarded object of kitchen, food waste etc, its moisture content are very high (typically 60 to 75%
Between), and because food is different, contain higher viscous material.Therefore the garbage sorting equipment or the whole series that early stage is introduced by developed country
Sorting factory system mostly ends in failure.Therefore the non-universe formula method of distributing of exploitation is discarded with reclaiming sorting Chinese rubbish, kitchen or food waste
Thing turns into a feasible method.On the one hand it is not need but wet method sorting seldom develops in conventional western countries, another aspect
If being to worry that such discarded object adds moisture, reluctant percolate can be formed.Therefore if the remaining discarded object after sorting is (main
Contain can pulp material, its content accounts for the at a relatively high ratio of former inlet amount, accounts for the 60 to 75% of most application of city life garbage amount
Weight in wet base, or higher) recycling can be carried out together with moisture with adding, the consideration just without diafiltration water problems.If such as remaining discarded object
Continue to carry out recycling with anaerobic fermentation, or the thermalization method of wet type, then wet method sorting will be very advantageous.Because such recycling
Technology, its moisture content demand is often 90% or so.
Wet method is sorted in addition to above-mentioned advantage, and its major advantage still includes following：
If carrying out appropriate gravity to adjust with waterpower, the sorting of more complete and more efficient fruit can be achieved in wet method sorting.Yin Li
With the centrifugation of gravity, flow velocity, and buoyancy or centrifugal force, can more disperse than merely with gravity and the effect of wind-force or inertia force
The material of different specific weight in rubbish.
Sorted using wet method, it is all can direct recovered material (such as metal, glass, plastics), not only separated
It is whole, more it can increase (such as the investigation recently of regenerant value in passing in stirring pulping process cleaning recovered material:Containing silt or
The recovery mixed plastic of swill, 1 ton is only capable of selling about 400 to 600 yuan!And clean mixed plastic can then sell 500 to 800
Member).
Universe method can be difficult separated plastics and stationery (or lignocellulose) and swill with slurrying by wet method sorting
Operation separation.Principle is:Lignocellulose and swill produce slurry after agitation, and plastics will not be into slurry, therefore can be easily
Separated with the sieve method of low energy consumption.
The sorting of universe method often applies jumbo, therefore often results in the air pollutions such as noise, foul smell and dust.Wet method sorts
Then less such secondary environmental pollution problem.
Unit operation needed for the sorting of universe method is more and complicated, and is mostly the hoisting machinery of power consumption.The operation of wet method sorting
It is then relatively simple, less consume energy.
Slurry recovery caused by wet method sorting, typically has higher economic benefit compared with universe method RDF recovery.
The equipment for using sorting slurrying at present, to pre-process kitchen garbage, such as CN103586109A,
The patents such as CN202893420U, CN103521503A, or CN202824087U, predominantly:It is sharp in closed cylinder or casing
Beaten with steel hammer rotation, or spiral extruder, so that the organic materials relevant with food stirs into slurry, then using rotating steel hammer
Centrifugal force and extruding force, or the extruding force of helical blade, slurry is extruded outside cylinder or casing by aperture under cylinder or casing.
And can not be into the metal, glass and plastics of slurry, then using fan and charging thrust, or helical blade thrust, toward cylinder or casing
Another end discharging opening transmits.Substantially these can not can not completely be sorted into the material of slurry in these above-mentioned pulping equipments.If it is intended to
Light material (i.e. plastics), and heavy material (i.e. metal, glass, silt particle) are sorted out again, typically there need to be another complete equipment for it, such as
CN202823589U carries out light, heavy material two classes with hydrocyclone and sorted.But this sorting device can not still carry out weight
The classification of metal and glass between material.If this two classes material still amalgamation, which rises, is just unable to reach really sorting recovery purpose.
Foregoing barrel type or box body shape pulping equipment is unable to reach the dual purpose of more complete sorting and slurrying.More
Have notably, because the said equipment be not beaten with steel hammer be exactly screw extrusion operation with slurrying and extrusion slurries.And part can not
The material of slurrying thing also often mixes causes not recuperability together, so that the defects of causing this kind equipment.In addition, this kind of slurrying is set
It is standby to still suffer from following shortcomings:
Heavy material does not sort substantially, not only causes the wasting of resources, more causes these discarded objects to exclude (must typically send
To landfill yard) the problem of.
This kind equipment need to provide hammering or rotary squeezing at a high speed.Simultaneously need to provide energy send out can not pulping materials, therefore
Power consumption is general higher.
Heavy material is not sorted and directly smashes, and not only causes mechanical wear, shortens equipment life, more causes particle to become
It can carefully be mixed into slurry, cause the impure of slurry, and influence recovery, or cause the stuck slewing of fragment and cause motor
Infringement.
This kind of pulping equipment structure is more complicated, causes dismounting inconvenience, and increase maintenance difficult falls.
