Abstract
The present invention discloses a refuse derived fuel (RDF) molding admixture, which is formed by mixing slaked lime, sawdust or straws, fly ash or coal residue powder, a water-soluble silicate and clay according to a certain ratio. According to the present invention, with the refuse derived fuel (RDF) molding admixture, the refuse derived fuel (RDF) is easy to produce and mold, and the prepared RDF solid fuel has characteristics of high strength, high toughness, good molding effect, easy combustion, high combustion heat value, and low dioxin emission.
Description
Technical field
The present invention relates to the processing technology field of domestic refuse, particularly relate to one way of life garbage derivatived fuel (RDF) shaping dopant.
Background technology
Along with the development of society, the quickening of urbanization process, urban population increases, living standards of the people improve, and the output of domestic waste is constantly increasing, and the composition of domestic refuse is also increasingly sophisticated, day by day serious to the harm of the pollution of environment and people ' s health, also limit the development in city.Existing trash processing way is landfill, burning and compost mainly.Landfill method floor space is large, easily pollutes underground water and air, and resource also can not get recycling.Although burning method processing efficiency is high, China's msw water content is high, calorific value is low, and need add high-grade fuel combustion-supporting, thus working cost is high; Meanwhile, the flying dust difficult treatment containing Dioxins and heavy metal, although adopt first and then complicated purification system, still containing micro-Dioxins in flue gas, enters topsoil environment; In addition, burning fails to make rubbish obtain maximum resource completely.Although compost is a good method, the treatment time is long, and floor space is large, and comprehensive benefit is poor.
The coal resources occupancy volume per person of China is lower, still faces energy dilemma, garbage derivatived fuel is prepared in rubbish combustibles sorting and is at home and abroad developed.Application number be 200610118086.3 Chinese patent disclose the invention of " preparation method of fuel derived from urban domestic garbage " by name, will through microbial decomposition, particularly to pick various garbage composition in the process of sorting, process numerous and diverse, having picked that plastics, bamboo wood, dry goods and paper etc. are multiple can the material of fuel combustion, cause waste, also post-processed is made troubles, and water ratio higher being unfavorable for burns.Application number be 201210138385.9 Chinese patent disclose the invention of " a kind of derivatived fuel based on domestic refuse combustibleconstituents and preparation method thereof " by name, application number be 97105046.5 Chinese patent disclose the invention of " a kind of method utilizing domestic refuse type of production to seek " by name, the common feature of these two kinds of technical schemes is that all to need additionally to add fine coal or bituminous coal etc. combustion-supporting.In current actual production, also rarely have to make after can realizing that domestic refuse is picked inanimate matter and be easy to burn and be directly used in the technical scheme of the fuel of industrial production or daily life.
Summary of the invention
The object of the present invention is to provide a kind of for crude waste is made the solid-fuelled domestic garbage derived fuel of RDF (RDF) shaping dopant after sorting removing inanimate matter is also pulverized.
Above-mentioned purpose of the present invention is realized by following technical proposal:
One way of life garbage derivatived fuel (RDF) shaping dopant, be made up of the raw material of following weight part:
White lime 1-4 part
Sawdust or stalk 7-15 part
Flyash or cinder powder 8-20 part
Water-soluble silicate 2-4 part
Clay 3-7 part
One way of life garbage derivatived fuel (RDF) shaping dopant, be made up of the raw material of following weight part:
White lime 3 parts
Sawdust or stalk 10 parts
Flyash or 10 parts, cinder powder
Water-soluble silicate 3 parts
Clay 5 parts
The preparation method of above-mentioned domestic garbage derived fuel (RDF) shaping dopant: namely the raw material Homogeneous phase mixing of above-mentioned weight part is obtained shaping dopant.
The action principle that the present invention is raw materials used:
White lime: remove the acidic substance such as sulfide, increases bounding force;
Sawdust stalk: promote material moisture homogenize, favourable shaping, increase calorific value;
Flyash cinder powder: increase plasticity, increases calorific value;
Water-soluble silicate: increase bounding force, reduces fly ash content when gasifying (burning);
Clay: make rubbish fragment (sheet) adhesion-molded.
The beneficial effect of domestic garbage derived fuel of the present invention (RDF) shaping dopant is used to be make domestic garbage derived fuel (RDF) be easy to making shaping; The obtained solid-fuelled intensity of RDF and toughness high, good forming effect, is easy to burning; Combustion heat value is high, and dioxin is few.

Clay 7 parts
embodiment three: the preparation method of above-mentioned domestic garbage derived fuel (RDF) shaping dopant: namely the raw material Homogeneous phase mixing of above-mentioned weight part is obtained shaping dopant.
One way of life garbage derivatived fuel (RDF) shaping dopant, be made up of the raw material of following weight part:
White lime 3 parts
Sawdust or stalk 10 parts
Flyash or 10 parts, cinder powder
Water-soluble silicate 3 parts
Clay 5 parts
The preparation method of above-mentioned domestic garbage derived fuel (RDF) shaping dopant: namely the raw material Homogeneous phase mixing of above-mentioned weight part is obtained shaping dopant.
Practical application through in June, 2013-2014 year April finds: domestic garbage derived fuel (RDF) the bar net effect made according to the proportioning in embodiment three is best.
The foregoing is only the preferred embodiments of the present invention, be not limited to invention, although with reference to previous embodiment to invention has been detailed description, for the technician in wooden field, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within all spirit in invention and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in invention.
