Abstract
Provided is a novel method of preparing regenerated coal from municipal solid waste. The method comprises the following steps: (1) crude sorting; (2) bag break; (3) magnetic separation; (4) screening; (5) degradation; (6) extruding dehydration; (7) drying; (8) crushing; (9) preparation of materials; (10) molding; (11) drying; (12) packaging of regenerated coal. The invention enables the problem of difficult disposal of municipal solid waste to be solved and the regenerated coal to be prepared from the municipal solid waste, and the regenerated coal has the advantages of a high heat value, no secondary pollution and stable combustion, thereby realizing resource utilization; the regenerated coal can be used to substitute fossil fuels, thereby enabling a great amount of national resources to be saved and actually turning the waste into the valuable; the method provided in the invention has the advantages of small investment and occupied land area, a short treating period and low operational cost.
Description
Technical field:
The present invention relates to a kind of recycling treatment process of domestic waste, particularly a kind of novel method of processing again soft coal with domestic waste.
Background technology:
Chinese city domestic refuse complicated component comprises waste paper, clothing cloth, dregs, metal, glass, rubbish from cooking etc., is difficult to handle effectively, and composting process in the present stage technology of garbage disposal, directly all there are certain defective in burning process, landfill process.For example for landfill disposal, not only floor space is big, and exists secondary pollution such as polluted source air, and at present a lot of big cities have been difficult to find suitable landfill place; Composting process, long processing period, and produce high-concentration waste water, be difficult to handle contaminate environment; Direct burning process, construction cost and operation cost are high, and consumes energy, have smoke pollution.Domestic waste is huge resource, and how more effectively treating refuse is turned waste into wealth, and is the direction that needs research at present.
In order to overcome the defective of prior art, the invention provides a kind of is the feedstock production method of soft coal again with the domestic waste, has promptly realized the processing of domestic waste, can produce the soft coal again of high heating value, non-secondary pollution again.
Summary of the invention:
Technical problem to be solved by this invention is: providing a kind of is the feedstock production method of soft coal again with the domestic waste.
Technical scheme of the present invention is:
A kind of new city domestic refuse is processed the method for soft coal again, it is characterized in that: domestic waste is carried out the following step handle:
(1) ragging: the combustible material and the unclassified stores of bulk are sorted out;
(2) broken bag: the plastics bag that domestic refuse will be housed breaks, and the sack materials inside is scattered, to make things convenient for subsequent disposal;
(3) magnetic separation: ferrous metal is sorted out;
(4) screening: sieve is the innoxious landfill of inorganic material down, and the screen overflow material is pulverized and made soft coal again, and organic materials carries out degradation treatment in the sieve;
(5) degraded: through steam the organic matter in the rubbish is degraded, under 1.1MPa and 180 ℃, degrade just to make organic water of constitution release in 1 hour, reached the effect of dehydration, and then the calorific value of raising material, became the coal-based material of good regeneration;
(6) extrusion dehydration: the extruding-desiccation machine that adopts our company to develop voluntarily carries out extrusion dehydration to the degraded material, can reduce material water ratio more than 30%, saves the energy;
(7) oven dry: adopt the drum-type drying method;
(8) pulverize: the degradation product after will dry and other combustible materials are together pulverized, as the base-material of soft coal again;
(9) batching: in the coal-based material of regeneration, add auxiliary materials such as a certain proportion of humic acids, unslaked lime, coal dust;
(10) moulding: according to the client and the market requirement, the soft coal again that output is fit to transportation and burns;
(11) oven dry;
(12) regeneration coal pack.
2, new city domestic refuse according to claim 1 is processed the method for soft coal again; It is characterized in that: the reaction kettle material loading is 30 minutes during degraded; To the logical steam of reaction kettle 60 minutes, under 1.1MPa and 180 ℃, the organic matter in the rubbish is degraded, organic water of constitution is discharged; Be incubated 30 minutes, draining 120 minutes.
3, new city domestic refuse according to claim 1 is processed the method for soft coal again, it is characterized in that: in the material of degraded back, add auxiliary materials such as humic acids, unslaked lime, coal dust, wilkinite during batching.
The invention solves the difficult problem that domestic waste is difficult to handle, process soft coal again, high heating value; Non-secondary pollution, flameholding has been realized recycling; Alternative fossil oil uses, and for country has saved ample resources, has reached real turning waste into wealth; And investment and floor space are little, and the processing cycle is short, and running cost is low.
Description of drawings:
Fig. 1 is a kind of process diagram of processing again soft coal with domestic waste.
Embodiment:
A kind of new city domestic refuse as shown in the figure is processed the method for soft coal again, comprises the following steps: (1) ragging: the combustible material and the unclassified stores of bulk are sorted out; (2) broken bag: the plastics bag that domestic refuse will be housed breaks, and the sack materials inside is scattered, to make things convenient for subsequent disposal; (3) magnetic separation: ferrous metal is sorted out; (4) screening: sieve is the innoxious landfill of inorganic material down, and the screen overflow material is pulverized and made soft coal again, and organic materials carries out degradation treatment in the sieve; (5) degraded: through steam the organic matter in the rubbish is degraded, under 1.1MPa and 180 ℃, degrade just to make organic water of constitution release in 1 hour, reached the effect of dehydration, and then the calorific value of raising material, became the coal-based material of good regeneration; (6) extrusion dehydration: the extruding-desiccation machine that adopts our company to develop voluntarily carries out extrusion dehydration to the degraded material, can reduce material water ratio more than 30%, saves the energy; (7) oven dry: adopt the drum-type drying method; (8) pulverize: the degradation product after will dry and other combustible materials are together pulverized, as the base-material of soft coal again; (9) batching: in the coal-based material of regeneration, add auxiliary materials such as a certain proportion of humic acids, unslaked lime, coal dust; (10) moulding: according to the client and the market requirement, the soft coal again that output is fit to transportation and burns; (11) oven dry; (12) regeneration coal pack.
