Description

Consumer waste comprehensively processing method
Technical field
The present invention relates to a kind of life refuse processing method, more particularly to a kind of rapid, innoxious and resources circulation are sharp With the consumer waste comprehensively processing method of change.
Background technology
According to statistics, China there are about 2/3 city and is absorbed in the predicament of garbage-surrounded city at present.The year of China's only domestic waste 1.5 hundred million tons nearby of yield, these domestic wastes are mostly air storage.It not only influences urban landscape, while dirty Contaminate and constituted very big threat with the vital big gas and water of our life and soil, the health to town dweller, rubbish has turned into One during urban development, social progress very thorny problem.And with the continuous improvement of living standards of the people, life Rubbish produce quantity is increasing, growth rate is increasingly faster (speed with annual 6% increases), composition is more and more multiple Miscellaneous, the harm that the life to the people is brought is also increasingly severe, and this has been the beyond dispute fact.
At present, house refuse mainly has three kinds of processing methods:
1st, landfill disposal
Landfill is the effective ways of a large amount of domestic wastes of dissolving, and is also the final of all garbage treating process residues Processing method, China generally uses direct landfill method.So-called direct landfill method is to insert rubbish on ready hole middle cover Compacting, brings it about biology, physics, chemical change, decomposing organic matter reaches minimizing and innoxious purpose.Directly fill Ground water degradation can be caused, the harm such as harmful toxic matter is produced.
2nd, burning disposal
Burning method is that rubbish is placed in high temperature furnace, makes the wherein a kind of fully oxidized method of combustible component, the heat of generation Measure for generating electricity and heating.The advantage of burning disposal is reduced training good (the residue volume reduction more than 90% after burning, weight Reduce more than 80%), processing is thorough.But burning method can cause the secondary pollution of environment, for example, contain in rubbish it is some Metal, is burned with very high toxicity, and the construction of incineration plant and producing cost are expensive.
3rd, compost treatment
House refuse is accumulated in heaps, insulation is to 70 DEG C of storages, fermentations, by the ability of microorganism decomposition in rubbish, will Organic matter resolves into inorganic nutrients.After compost treatment, house refuse becomes health, tasteless humus.Both rubbish is solved The outlet of rubbish, can reach the purpose of renewable resources again, but consumer garbage compost amount is big, and nutrient content is low, and long-term use is easily made Degenerated into soil hardening and groundwater quality, so, the scale of compost is difficult too big.
It is therefore desirable to provide a kind of method of new, efficient and environmentally friendly processing house refuse, make house refuse can Used with circulating by people, it is to avoid the generation of secondary pollution.
The content of the invention
The defect existed for prior art, the invention provides a kind of rapid, innoxious and resource circulation utilization Consumer waste comprehensively processing method.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of consumer waste comprehensively processing method, is comprised the technical steps that:
1) roughing:By the totters in house refuse, the building waste of bulk, and wood, summer sleeping mat etc are not allowed fragile Broken foreign matter separation;
2) feeding:
2-1, using forklift house refuse is delivered on board-like charging gear by receiving cone;
House refuse is delivered to feeding ribbon conveyer by 2-2, board-like charging gear by uniform poking device;
3) magnetic separation:House refuse is delivered to by ferromagnetic deironing device by feeding ribbon conveyer, ferromagnetism thing therein is selected Matter;
4) crushing and screening:House refuse after magnetic separation is delivered in refuse grinder, and refuse grinder is by the larger life of particle diameter Rubbish living is crushed, and the house refuse after crushing is entered back into is sieved in one-level cylinder round sifter, obtains screenings and sieve Upper thing;
5) selection by winnowing:The oversize obtained in step 5 delivers to pneumatic separation device through oversize belt feeder by oversize elevator Heavy substance, micro- heavy substance and light materials are sub-elected, heavy substance delivers to ferromagnetic deironing device through heavy substance belt feeder, isolates therein Ferromagnetic material, light materials are delivered to light materials baling press by light materials elevator through light materials belt feeder and gone out, and are packed,;
6) secondary magnetic separation:The screenings obtained in step 5 delivers to ferromagnetic deironing device through screenings belt feeder, isolates wherein Ferromagnetic material, then deliver to and sieved in two stage cylinder screening machine again, obtain screenings and oversize, screenings passes through Some screenings belt feeders are transferred out of, and can both do basis filling auxiliary material, it can also be used to brickmaking;
7) anaerobism is carbonized:
On the sieve obtained in heavy substance and step 7 after 7-1, micro- heavy substance that step 6 selection by winnowing is obtained, step 6 magnetic separation Thing is delivered to be carbonized in anaerobism retort, obtains coal, and produce a certain amount of fuel gas;
7-2, by gas fuel burning, calory burning is carbonized for anaerobism, and surplus heat can be used for one-level industry heating;
Sold outside 7-3, the obtained coal of charing, available for warming oneself, cook and generate electricity.
Apparatus of the present invention compared with prior art, use one-level cylinder round sifter, two stage cylinder screening machine, ferromagnetic deironing device Mechanization processing is carried out to house refuse with anaerobism retort, crushing and screening is first carried out, then carries out magnetic separation, strong magnetic is substantially increased The service efficiency of tramp iron separator, is realized to being the harmless treatment of rubbish of working, while present invention side by anaerobism retort Coal, heat energy and construction timber house refuse can be made in method, realize the effect turned waste into wealth of rubbish.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the process chart of the present invention.
Embodiment
As illustrated, a kind of consumer waste comprehensively processing method, is comprised the technical steps that:
