Description
Technical field
The present invention relates to the processing technology of domestic garbage.
Background technology
Because the develop rapidly of national economy, urban population is intensive, and the production in city and resident living consumption strengthen day by day, thereby a large amount of domestic garbages occurred.Existing house refuse is divided into following a few class basically: can rotten organic matter class comprise kitchen waste, melon, pericarp, bone, animal residue, wood, bamboo, grass, people, animal ight soil, cotton wool goods etc., organic feed and fertilizer can be processed into after their classification, a large amount of biogas can be produced; The organic matter class comprises plastic products class, fabric fiber-like, paper products rubber-like etc., can be reprocessed into plastic products, paper products rubber and fuel etc.; The inorganic matter class comprise brick, watt, stone, coal ash, glass etc., can be processed into the building material therefor; Metal species can be processed into raw metal and metallic article.The method that prior art is handled house refuse is with cram packer rubbish to be transported to destructor plant; the rubbish that ships is compressed processing; to compress the rubbish of handling again and transport to garbage loading embeading factory; landfill factory is with the underground anticorrosion water-proofing treatment protection of having carried out multilayer, and the rubbish with compressed processing carries out landfill disposal again.But this landfill disposal method land occupation resource; And can not eliminate a large amount of pathogen, poisonous and harmful element and gas contained in the rubbish, pollute the environment in case take place to reveal.
Summary of the invention
The purpose of this invention is to provide a kind of free from environmental pollution, not land occupation resource, the domestic garbage processing process that can turn waste into wealth, to solve the problem that prior art exists.
In order to realize purpose of the present invention, the technical solution used in the present invention is:
Domestic garbage processing process comprises the steps:
(1), primary election:
House refuse is sent in the trundle screen of screening installation, filter out diameter less than 20mm can rotten organic matter and part inorganic matter rubbish;
Simultaneously the house refuse in the trundle screen is carried out fragmentation, filter out the house refuse of diameter after the fragmentation less than 20mm;
With high wind equipment the house refuse in the trundle screen is carried out selection by winnowing simultaneously;
(2), selected:
Above-mentioned diameter is carried out wet concentration less than the house refuse of 20mm, with can rotten organic matter separating of lighter weight with the heavier part inorganic matter of quality;
High wind equipment is delivered to polybag, Polypropylence Sheet, paper, foamed product house refuse in the magazine far away, with moulding the paper separation equipment plastics and paper is separated;
Heavier plastic products, rubber, the forward propulsion effect of breaker in trundle screen of metal species house refuse remaining in the trundle screen fall in the magazine;
Utilize electromagnet to isolate metal species rubbish;
(3), with the lighter weight of selected back gained can rotten organic matter, the heavier part inorganic matter of quality; Polybag, Polypropylence Sheet, foamed product, paper; Heavier plastic products, rubber, the metal species rubbish of quality carries out processing, makes product.
Described can rotten organic matter processing comprising the steps:
With in the fermentation tank that can rotten organic matter rubbish be extracted into sealing after selected sealing and fermenting 7-8 days with pump, again after nontoxic processing, in ware, remove moisture content by pump suction material moisture, produce organic feed and organic fertilizer with feed granulation production equipment, granulation of fertilizer production equipment; The biogas that produces in the fermentation tank is sent into gas compressor through pipeline, and the gas of compression enters air accumulator, biogas is sent into production equipment and the power plant that heats with biogas by air accumulator again.
Described Polypropylence Sheet, polybag, foamed product processing comprise the steps:
Raw material from the feeding port material loading, is squeezed into stripe shape through plastics extruding sett frame, after water cooling, enters plastics heating comminutor and form industrial chemicals.
Described Polypropylence Sheet, polybag, foamed product processing comprise the steps:
Send into after the inorganic matter of the plastic raw materials with 30% and natural sand of 70% and sorting is pulverized and rotate in the mixer, heating is dissolved the plastic raw materials that rotates in the mixer, in the fusion process with the abundant combination of inorganic matter, enter formed product equipment, through die pressure processing, manufacture required product again.
Heavier plastic products, the rubber processing of described quality comprises the steps:
Solid plastic, rubber through sorting out transport with conveyer belt, in transport process, industrial chemicals such as the Plastic Drum in the raw material, plastic plate, solid plastic woven bag are elected, produced industrial chemicals with disintegrating machine or heating comminutor with artificial or other method; Other raw material is heated and produced as fuel oil through rotating refining equipment, and the bits carbon black of refining oil adds coal slime and produces honeycomb briquette or coal briquette.
Described stationery raw material processing comprises the steps:
Through moulding the paper pulp that produces after the paper separation equipment separates, through pulp pump, suction paper separator,, take off the moisture content in the paper pulp by the paper separator, pass through compression forming equipment again, processing is pressed into the paper piece of square, becomes stationery raw materials for production product;
Described metal species raw material processing comprises the steps:
The old metal raw material of many places sorting is concentrated in together, dissolve,, produce product again through the ingot iron mould or directly pass through product mold through the heating of electric iron-smelting furnace.
Advantage and effect that the present invention had are:
1, this technology advanced person, reasonable in design, processing speed fast, can disposable house refuse be processed into product, invest for a short time, economic results in society are big.
2, this technology has been broken the technology of landfill and burning processing house refuse, has solved secondary pollution and potential safety hazard, has broken the technology of artificial separation, adopts pipelining, can make all house refuses all become useful material, brings benefit to the people.
3, can bring very high economic benefit with this PROCESS FOR TREATMENT house refuse:
1,000 tons of domestic rubbish disposal processing factories are as the criterion with the day processing.
1, can rotten organic content be 70% in every kiloton house refuse
Remove moisture content 70% after 1 kiloton * 70%=700 ton * processing
700 tons * 30%=210 ton
Every kiloton house refuse can produce 210 tons of feeds and fertilizer by rotten organic matter, feed and fertilizer are by 100 yuan of/ton calculating.
2, the content of waste plastics, scrap rubber, paper-like materials is 15% in every kiloton house refuse
1 kiloton * 15%=150 ton
Every kiloton house refuse can be produced 150 tons of waste plastics, scrap rubber, paper-like materials, by 200 yuan of/ton calculating
150 tons * 200/ ton=30000 yuan
3, inorganic content is 10% in every kiloton house refuse
1 kiloton * 10%=100 ton
4, the content of old metal and other materials is 5% in every kiloton house refuse
1 kiloton * 5%=50 ton
Metallic iron in every kiloton house refuse and other materials are by 300 yuan of/ton calculating
50 tons * 300 yuan/ton=15000 yuan
21000 yuan+30000 yuan+15000 yuan=66000 yuan
It is exactly 6.6 ten thousand yuan together that the above 4 prong material benefits that house refuse is elected after selected add, and this does not also comprise the benefit after the processing such as biogas production.
For example: calculate by above that to produce destructor plant day every day benefit be 6.6 ten thousand yuan, the annual year benefit of calculating by 300 working days is: 6.6 ten thousand yuan * 300 days=19,800,000 yuan
4, adopt garbage treating process of the present invention, can polluted source, air, help environmental protection.
