Description

A kind of rubbish pretreatment supporting with refuse burning system and efficient resource metallization processes
Technical field
The present invention relates to technical field of domestic garbage treatment.
Background technology
Current China house refuse annual production about more than 1.5 hundred million ton, and every year with 8% speed increase, and the volume of cargo in storage over the years of China's rubbish reaches more than 60 hundred million tons, occupies a large amount of land resource.According to estimates, in China 668 cities, the city of 2/3rds is about had to be in rubbish encirclement.
Existing domestic rubbish disposal is disposed pattern and is mainly contained three kinds, landfill, burning and compost etc., and domestic garbage resource technique also day by day increases, and it is mainly by the impact of following factor: (1) technological applicability and the degree of reliability; (2) disposal cost and ability to bear; (3) environmental pollution and Environmental capacity; (4) resource value and some the special restriction factor etc.
Landfill is economized from investment viewed from capital expenditure aspect most, the lowest coursing cost, and technology content is relatively low, but some comparatively flourishing coastal cities, the problem that landfill yard is faced with land resources utilization contradiction, environmental protective measure is difficult to is thorough, project occupation of land area is large.
For compost, because China have employed mixed collection mode, waste component is very complicated, make compost pre-treatment requirement very strict, and composting production does not have rational market substantially.
Burning disposal mainly as far as possible incinerating waste material, specifically, mainly contain following advantage: (1) project occupation of land area is little; (2) stable, health, reliable, fraction is high, totally-enclosed industrialized production model, substantially not by effect of natural conditions, to guarantee incineration plant round-the-clock running, and can reach more than 20 years service life; (3) take up an area little, pollute low feature, make incineration plant be built in urban district, thus greatly reduce the freight of rubbish; (4) burn the energy in recyclable rubbish, turn waste into wealth.
But containing more mixed waste plastic in house refuse, waste plastics is directly carried out burning disposal, causes serious secondary pollution by environment.When plastics burn, not only produce a large amount of black smoke, and can bioxin be produced, serious harm environment.
In sum, the current Prediction for Solid Waste Treatment Technology of China is in reduced levels substantially, is difficult to realize innoxious, the resource of garbage disposal, minimizing, industrialization.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of rubbish pretreatment supporting with refuse burning system and efficient resource metallization processes, the features such as domestic rubbish disposal is innoxious, resource, minimizing, industrialization that it has.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
The rubbish pretreatment supporting with refuse burning system and an efficient resource metallization processes, technique comprises the following steps:
A, by bag-breaking machine breaking refuse bag, the house refuse being placed in refuse bag to be come out;
B, by percolate treating process by the house refuse drop after broken bag except most of percolate;
C, drop is carried out screening separation except the house refuse of most of percolate, isolate oversize and screenings;
D, by oversize and screenings respectively by magnetic plant by ferromagnetic separation and recovery;
E, oversize is isolated the upper heavy thing of sieve and the upper lightweight thing of sieve through drainage wind optional equipment;
F, lightweight thing on sieve is reclaimed a dry-dressing machine through waste or used plastics essence point isolate waste plastics and the upper light weight sundries of sieve;
G, heavy thing on screenings, sieve and the upper light weight sundries of sieve to be uniformly mixed, to adopt drying plant to dry afterwards, make said mixture material moisture content be reduced to about 10%, enter incinerator burning electricity generation afterwards;
H, by the waste plastics separated in step f through cracking oil refining apparatus, produce the products such as heavy oil, combustible gas and carbon black.
The present invention improves further and is:
After completing steps b, again by bag-breaking machine, broken bag process is carried out to the house refuse that drop removes percolate, the house refuse be wrapped in refuse bag of omitting is come out.
When in step g, the mixed material of drying plant to heavy thing on screenings, sieve and the upper light weight sundries of sieve is dried, the drying plant of employing is rotation-roll type drying plant, and the heat energy that rotation-roll type drying plant adopts is the high-temperature flue gas waste heat that incinerator produces.
When in step g, the mixed material of drying plant to heavy thing on screenings, sieve and the upper light weight sundries of sieve is dried, the drying plant of employing is rotation-roll type drying plant, and the heat energy that rotation-roll type drying plant adopts is the high-temperature flue gas waste heat that cracking oil refining apparatus produces.
The beneficial effect adopting technique scheme to produce is:
The present invention has the following advantages: (1) improves changing waste into resources: this technique and garbage burning factory support the use, and is sub-elected by waste plastics in house refuse in order to oil refining, improves domestic garbage resource value; Ferromagnetic is sub-elected, can in order to recycle.(2) harmless treatment rate is high: burn leftover materials after being therefrom separated by waste plastics most of in house refuse, greatly can reduce the generation of bioxin.(3) can ensure that incineration plant is normally run and under producing the constant prerequisite of electricity daily, utilizes efficient resource in house refuse, but do not increase operating cost.(4) operating cost is low, utilizes the high-temperature flue gas waste heat recovery of incinerator or distillation system to provide heat energy for drying system.The present invention has the features such as domestic rubbish disposal is innoxious, resource, minimizing, industrialization.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further elaborated.
The house refuse entering garbage burning factory first will wherein break by bagged articles after first time, dissepiment limit material machine and bag-breaking machine, for abundant draining provides condition, bring storage bin into, remove most of percolate by percolate treating process through a few days drop by conveying; Again by bag-breaking machine, broken bag process is carried out to the house refuse that drop removes percolate, the house refuse be wrapped in refuse bag of omitting is come out; The house refuse that drop falls most of percolate is divided into oversize and screenings by rotary screen; By oversize and screenings respectively by magnetic separator by ferromagnetic separation and recovery; Oversize is isolated the upper heavy thing of sieve and the upper lightweight thing of sieve through gravity winnowing machine; Lightweight thing on sieve is reclaimed dry-dressing machine through waste or used plastics essence point and isolates waste plastics and the upper light weight sundries of sieve; The waste plastics separated is entered cracking oil refining apparatus, produces the Product recycling such as heavy oil, combustible gas and carbon black; Heavy thing on remaining screenings, sieve and the upper light weight sundries of sieve are uniformly mixed, rotation-roll type drying plant is adopted to dry afterwards, the heat energy that rotation-roll type drying plant adopts is the high-temperature flue gas waste heat that incinerator produces, also the high-temperature flue gas waste heat that cracking oil refining apparatus produces can be adopted, make said mixture material moisture content be reduced to about 10%, enter incinerator burning electricity generation afterwards.The present invention has the features such as domestic rubbish disposal is innoxious, resource, minimizing, industrialization.
