Abstract
The invention discloses a method for preparing a regenerated fuel. The method comprises the following steps of: sorting household garbage, separating organic matters, plastics, ironware, glass, and the like, performing degradative reduction on the organic matters, and performing full degradation at the temperature of between 160 and 200 DEG C and under the pressure of between 0.6 and 1.5 MPa in the presence of a catalyst; after degradation, screening solid products to obtain oversize products and undersize products; and pressing and molding the undersize products into the regenerated fuel by using molding equipment. The fuel produced by the method can greatly reduce the environmental pollution in the combustion process and avoid harm to the environment and human bodies, also can utilize the thermal energy of the fuel to the greatest degree, has the advantages of simple production technology, good combustion performance, and the like, and realizes reclamation, reduction and harmless treatment of the garbage.
Description
Technical field
The invention belongs to a kind for the treatment of process of domestic refuse degradation treatment process product, particularly a kind of preparation method of regenerated fuel.
Background technology
The domestic refuse complicated component, but be broadly divided into organism, inorganics and recyclable waste product etc.Domestic rubbish disposal turns to target with innoxious, minimizing and resource, mainly contains sanitary landfill, biochemical compost, waste incineration, recycling four big technology municipal wastes is handled.Wherein the final product of organism recycling is mainly fertilizer and garbage derivatived fuel.Though the production method of garbage derivatived fuel is arranged at present, but it is more to contain impurity in the product, still has certain degree of difficulty and pollution in combustion processes both at home and abroad.Therefore, we need a kind of technology of environmental protection more, allow garbage derivatived fuel become a kind of eco-friendly new forms of energy.The present invention proposes the novel method-regenerated fuel of organism recycling.Organic matter in the domestic refuse is pressed into fuel brick again through degradation treatment, can improve its combustionproperty, and reduce its water content.
Summary of the invention
Technical problem to be solved by this invention is: a kind of preparation method of regenerated fuel is provided and uses combustion method.With the rubbish better utilised, processing and manufacturing goes out a kind of high heating value, the low fuel that pollutes, easily stores.
Technical scheme of the present invention is:
A kind of preparation method of regenerated fuel is characterized in that:
(1) sorting, degradative reduction
With domestic refuse through sorting, isolate organic matter, plastics, ferrous products, glass etc., organic main component wherein is starch, fat, Mierocrystalline cellulose, xylogen etc., organic matter is carried out degradative reduction, fully degrade down in 160-200 ℃, 0.6-1.5MPa, catalyzer (sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid or in controlling catalyst at least a or several) effect;
(2) screening
After degraded was finished, the solid product via hole diameter was screen overflow and the screen underflow that the screening of 8～12mm sieve obtains; The main component of screen underflow is the degraded product of Mierocrystalline cellulose and xylogen.
(3) moulding
Screen underflow with send into molding device after additive mixes, be suppressed into regenerated fuel through molding device and be suppressed into regenerated fuel through molding device.
Additive t ratio is;
Screen underflow 70-90 part
Humic acids 10-20 part
Unslaked lime 5-10 part
More than the component of each raw material be weight part.
After degraded was finished, the solid product via hole diameter was screen overflow and the screen underflow that the screening of 8～12mm sieve obtains.
Regenerated fuel according to a kind of preparation method of regenerated fuel preparation.
Effect of the present invention is:
This method is utilized the repressed regenerated fuel that is shaped to of organic matter degradation processing product in the domestic refuse, through preceding sorting, other combustiblecomponentss such as plastics in the rubbish is sub-elected, and makes the composition in the fuel simple relatively, has reduced objectionable impurities wherein.The fuel that this method makes can utilize the heat energy of fuel to greatest extent, and production technique is simple, and advantage such as have the calorific value height, have good burning performance has realized resource utilization, the minimizing, innoxious of rubbish.

Embodiment
The preparation method of a kind of regenerated fuel as shown in Figure 1:
(1) sorting, degradative reduction
With domestic refuse through sorting, isolate organic matter, plastics, ferrous products, glass etc., organic matter is wherein carried out degradative reduction, fully degrade down in temperature 160-200 ℃, pressure 0.6-1.5MPa, catalyzer (sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid or in controlling catalyst at least a or several) effect;
(2) screening
After degraded was finished, the solid product via hole diameter was screen overflow and the screen underflow that trommel screen (or vibratory screening apparatus) screening of 8-12mm obtains;
(3) moulding
Screen underflow 75 weight parts, humic acids 20 weight parts, unslaked lime 5 weight parts are sent into molding device after mixing, and are suppressed into regenerated fuel through molding device.
Wherein (3) moulding
Or screen underflow 70 weight parts, humic acids 10 weight parts, unslaked lime 5 weight parts send into molding device after mixing, and are suppressed into regenerated fuel through molding device.
Or screen underflow 90 weight parts, humic acids 20 weight parts, unslaked lime 10 weight parts send into molding device after mixing, and are suppressed into regenerated fuel through molding device.
After tested, the regenerated fuel thermal value that present method makes reaches more than the 16728kJ/kg, and alternative coal has been saved former coal resource as fuel.
Claims (3)
