Description
Technical field
The invention patent relates to the pre-treatment classification sorting recovery methods in relation to solid waste in field of environment protection.This law carries
It has supplied a kind of hygroscopic water to pick and the equipment of slurrying, has been mainly used for recycling rubbish and the kitchen directly collected by restaurant or via source point
It picks containing can directly recycle and send to materials such as the metals, glass, plastics of recycling factory in rear remaining kitchen waste, simultaneously
Slurry is made in surplus material after sorting in case the further recycling of biochemical process or thermalization method, reaches waste full resource
Change and the almost purpose of zero-emission.
Background technology
The sorting of rubbish is classified, 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, is the method for distributing of universe formula often.Such methods generally after garbage bag breaking using grain sorting (such as
With the equipment such as drum screen or other sieve methods), 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 can also carry out light point-score to separate glass again
Glass.Certainly it can also design wind-force and close " knife point-score " (the Air Knife) of And with inertia to separate the material of different specific weight.And it is light
Class material, such as plastics, stationery, the wooden organic matters such as class and swill, then because proportion is similar (generally between 0.8 to 1.2)
More difficult separation.Many reclaims factories often claim the term that such light material crushes and industry prevalence is made again to RDF
(Refuse Derived Fuel).Such RDF can do fuel applications, or send to incinerator to recycle the energy.RDF also can be through
Compost is made by biochemical process (biochemical process), or applies inhomogeneous thermochemical method, such as wet oxidation recycles chemicals
And the energy, or recycle 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 flourishing western countries' rubbish center sorting factory.Because the moisture content of west rubbish is generally relatively low, about
Between 25 to 35%, also contain less wet viscous material, Gu Lajifenjianchang is easier to use universe Sorting Technique.
There are still some defects, such as organic matter (such as plastics, textile fabric, swill, paper for current universe Sorting Technique
Class, wooden class etc.) between because proportion and many physical property are close to (generally between 0.8 to 1.2, non-conductive) and difficult traditional technology point
It picks.And inorganic weight class (general proportion>2), the iron in removing heavy metals, outside aluminium, unclassified stores more difficult economical and effective separation.
The waste of especially oriental rubbish or kitchen, food waste etc, moisture content are very high (generally 60 to 75%
Between), and because different from west food, contain higher viscous material.Therefore the garbage sorting equipment that early stage is introduced by developed country
Or a whole set of sorting factory system mostly ends in failure.Therefore the non-universe formula method of distributing of exploitation is to recycle the Chinese rubbish of sorting, kitchen or kitchen
Remaining waste becomes a feasible method, most important to the recycling of resource.But wet method is sorted in previous western countries
It seldom develops and uses, does not on the one hand need, if another aspect is to worry that moisture is added in such waste, can be formed reluctant
Percolate.Therefore if after sorting remaining waste (it is main containing can pulp material, content accounts for the quite high ratio of former inlet amount
Example, accounts for about 60 to 75% weight in wet bases or higher of most application of city life garbage amount) recycling can be carried out with being added together with moisture, just
The considerations of without diafiltration water problems.If such as remaining waste continues with the thermalization method progress recycling of anaerobic fermentation, or wet type, then
Wet method sorting will be very advantageous.Because such resource technology, moisture content demand is often 90% or so.
Wet method sorts in addition to above-mentioned advantage, and major advantage still includes following：
If carrying out gravity appropriate to adjust with waterpower, more complete and higher effect can be achieved in wet method sorting
Sorting.Because of the centrifugation using gravity, flow velocity, and buoyancy or centrifugal force, compared with merely with gravity and wind-force or inertia force
Effect can more disperse the material of different specific weight in rubbish.
Sorted using wet method, it is all can directly recovered material (such as metal, glass and plastics), not only may be used
It detaches more complete, more can increase (such as the investigation recently of regenerant value in passing in stirring pulping process cleaning recovered material:
Recycling mixed plastic containing silt or swill, 1 ton is only capable of selling about 400 to 600 yuan!And clean mixed plastic can then be sold
500 to 800 yuan).
Universe method can be difficult that separated plastics and stationery (or lignocellulose) and food are residual by wet method sorting
Slag is detached with pulp making operations.Principle is:Lignocellulose and swill generate slurry after agitation, and plastics will not be slurried,
Therefore the sieve method of low energy consumption can be used to detach easily.
Jumbo is often applied in the sorting of universe method, 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 energy consumption.Wet method point
The operation picked is then relatively simple, less consumes energy.
The slurry recycling that wet method sorting generates generally has higher economic benefit compared with the RDF recycling of universe method.
At present using the equipment of sorting slurrying, to pre-process kitchen garbage, such as CN103586109A,
The patents such as CN202893420U, CN103521503A, or CN202824087U, predominantly:It is sharp in closed cylinder or babinet
It is beaten with steel hammer rotation, or spiral extruder, so that organic materials related with food stirs into slurry, then utilizes rotation steel hammer
Centrifugal force and extruding force, or helical blade extruding force, slurry is squeezed out by aperture under cylinder or babinet outside cylinder or babinet.
And metal, glass and the plastics that can not be slurried, then utilize fan and charging thrust, or helical blade thrust, toward cylinder or babinet
Another end discharge port transmits.Substantially these materials that can not be slurried can not be sorted completely in these above-mentioned pulping equipments.If being intended to
Light material (i.e. plastics), and heavy material (i.e. metal, glass, silt particle) are sorted out again, generally there need to be another complete equipment for it, such as
CN202823589U carries out light, heavy material two classes with hydrocyclone and sorts.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 recycling purpose.
Barrel type or box body shape pulping equipment above-mentioned is unable to reach the dual purpose of more complete sorting and slurrying.More
Have notably, because above equipment is not to be beaten to be exactly the operation of screw extrusion with slurrying and squeeze out slurries with steel hammer.And part can not
The material of slurrying object also often mixes causes not recuperability together, so that causing the defect of this kind of equipment.In addition, this kind of slurrying is set
It is standby that there are still following disadvantages:
Heavy material does not sort substantially, not only results in waste of resources, and more causes these wastes that must arrange
The problem of except (must generally send to landfill yard).
This kind of equipment need to provide high speed hammering or rotary squeezing.Energy submitting need to be provided simultaneously can not slurrying
Material, therefore it is general higher to consume energy.
Heavy material is not sorted and directly smashes, and not only leads to mechanical wear, shortens equipment life, more makes
Attenuate at particle and can be mixed into slurry, cause the impure of slurry, and influence recycling, or cause the stuck slewing of fragment and
Motor is caused to damage.
This kind of pulping equipment structure is more complex, causes dismounting inconvenient, increases maintenance difficult.
