According to the technical scheme, the garbage sorting treatment method is characterized by comprising the following steps: drying, performing dust screening, winnowing, crushing, de-magnetizing, winnowing, performing water separating, crushing, winnowing, hydrolyzing and discharging hydrolyzed garbage from a hydrolysis tank.
Description
Technical field
The present invention relates to a kind of garbage reclamation technique field, specifically refer to a kind of refuse classification processing method.
Background technology
According to statistics, China about has the city of 2/3rds to be absorbed in the predicament of garbage-surrounded city at present.The annual production 1.5 hundred million tons nearby of China's only domestic waste, these domestic waste overwhelming majority are air storages.It not only affects urban look, pollutes vital air, water and soil with our life simultaneously, forms very large threat to the health of town dweller, and rubbish has become in urban development, social progress process one very thorny problem.And improving constantly along with living standards of the people, the quantity that house refuse produces is increasing, growth rate more and more faster (speed increment with annual 6%), constituent becomes increasingly complex, and the harm brought to the life of the people is also more and more serious, and this has been the beyond dispute fact.
At present, domestic garbage disposal does not also have a kind of well solution, and what now generally adopt has three kinds of methods: one is landfill; Two is burn and burning electricity generation; Three is compost.Now concrete analysis is as follows:
First method: landfill; The waste disposal method that current employing is maximum.This method seems simple, but harm is very large, and its shortcoming is: floor space is large, holding time is long, and the rubbish after landfill causes severe contamination to soil, underground water, air, and its reality harm and potential hazard are especially in continuous increase.
Second method: burn and burning electricity generation.This method surface seems the minimizing and resource that achieve garbage disposal, but also there is following problem: also need reprocessing by the slag of the 40-50% after burning, also needs landfill to continue polluted underground water and soil
The third is compost, and the method has small investment, a little easy-operating, but there is following shortcoming: the organic matter heap rotten time needed is longer, and organic matter degradation is not thorough.
In sum, the current Prediction for Solid Waste Treatment Technology of China, substantially for low level, is difficult to realize innoxious, resource and the industrialization of garbage disposal.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of land occupation area little for above-mentioned technical problem, and the processing time is short, avoid polluting, operating cost is low, effectively process pernicious gas, institute produces that product quality is high, nothing remains, the refuse classification processing method of non-secondary pollution
The present invention's adopted technical scheme that solves the problem is: a kind of refuse classification processing method, is characterized in that, comprise the steps:
A, oven dry, be transferred to rubbish on conveyer belt, by conveyer belt, rubbish sent into dryer and carry out drying operation;
B, sieve dirt, be expelled to conveyer belt by the rubbish after drying from dryer discharging opening, to be sent in rotary screen by rubbish and to carry out, sifted out by the tiny rubbish such as dust by conveyer belt;
C, selection by winnowing, topple over the rubbish after the dirt that sieves on a moving belt, and send into pneumatic separation device by conveyer belt from rotary screen, by selection by winnowing by Plastic rubbish air blasting out stored in the first garbage recovery device;
D, fragmentation, send into rubbish remaining after selection by winnowing in garbage crushing device and carry out break process;
E, degaussing, be poured onto on conveyer belt by the rubbish after steps d fragmentation, above conveyer belt, be provided with electromagnet, carries out degaussing material operation to the rubbish on conveyer belt, and magnetic material absorption got up is stored in the second garbage recovery device;
F, selection by winnowing, repeat step c by rubbish remaining after step e, equally will by selection by winnowing by Plastic rubbish air blasting out stored in the first garbage recovery device;
G, wet concentration, by the rubbish after f step through wet concentration equipment, wet concentration goes out floating rubbish and overflows wet concentration equipment by overflow manner and then drop on netted conveyer belt, and the rubbish sunk in water choosing device is discharged by discharge gate;
H, fragmentation, repeat Step d by rubbish floating after wet concentration step,
I., selection by winnowing, be sent to by conveyer in the pipeline of vertical hollow by the rubbish after h step, the tube wall place of pipeline is provided with multiple blower fan, by the rubbish that naturally falls from pipeline by blower fan selection by winnowing;
J, hydrolysis, be delivered to the rubbish falling into ground through i step by conveyer belt in the inherent hydrolytic decomposition pot of hydrolytic decomposition pot and add weight ratio and be 0.5% and concentration is the concentrated sulfuric acid of 98%, and steam pressurized, to 0.8 ~ 1Mpa, airtight pressurize half an hour, is hydrolyzed;
K, by through j step hydrolysis after rubbish discharge from hydrolytic decomposition pot.
Can find out that tool of the present invention has the following advantages according to such scheme: after being dried by rubbish, can prevent moist rubbish from affecting refuse classification, the rubbish sieve of dust one class can go through the dirt that sieves by the rubbish after drying, this kind of rubbish can directly be buried can't affect environment, also can as the raw material of construction material, sieve the rubbish after dirt through selection by winnowing by lighter rubbish air blasting out simultaneously, this kind of rubbish is generally the material such as plastics or foam rubbish, enter the first garbage recovery device, this kind of rubbish can send into chemical plant as raw material, rubbish after selection by winnowing carries out break process, because have some to remain plastics or foam class material could not be gone by first time wind riddle because of overweight, material after fragmentation is through magnetic separation, can by the magnetic material sucking-off in rubbish, this kind of material can be recycled as the raw material of magnetic material factory, rubbish after degaussing is through repeatedly selection by winnowing and wet concentration remain to the plastics in the rubbish after fragmentation and foam class material be separated out, finally remaining organic matter add appropriate concentration be 98% the concentrated sulfuric acid make catalyst, pass into high steam and be pressurized to 0.8 ~ 1Mpa, airtight pressurize is hydrolyzed half an hour, degradable organic waste after hydrolysis can be directly used in the manufacture of fertilizer, can find out through refuse classification process repeatedly from above rubbish technique, recycle after recuperable garbage reclamation most in rubbish, irretrievable rubbish is as silt, pottery, the inorganic refuses such as masonry can be directly used in landfill or make construction material, environmental pollution can not be caused, simultaneously large at minimizing amount of landfill, effective saving land resource.
As improvement, the operation of sieve dirt can be carried out through a b step again at the rubbish after step c selection by winnowing; Can go by the more further rubbish sieve by dust class, thus improve the efficiency of the steps such as fragmentation, degaussing.
As improvement, the multiple blower fans described in i winnowing step refer to four blower fans, and the air port of four described blower fans is arranged on the tube wall of the pipeline of vertical hollow respectively; Because be last selection by winnowing, so establish multiple blower fan can improve selection by winnowing efficiency on tube wall.
