Embodiment 1

[0071] In this embodiment, the composition and weight percentage ratio of a derived fuel based on the combustible components of domestic waste is: 65% of combustible components of domestic waste, 30% of bituminous coal, 2.5% of calcium oxide, 1.5% of industrial cornstarch, Sodium Humate 1.0%. The preparation steps are as follows:

[0072] (1) Separating municipal solid waste into long strips of plastics and textiles through two-stage trommel bag breaking and hanging, and then separating plastics, waste paper and For textile fragments, the double air chamber multi-functional air separator separates plastics, waste paper and textile fragments, and after further air separation, the combustible components of domestic waste composed of waste paper and textiles are separated;

[0073] (2) Use a rotary dryer to dry the combustible components of domestic garbage at a drying temperature of 200°C to reduce the moisture content to 25%;

[0074] (3) Use a shear crusher to crush the comb...

Embodiment 2

[0087] In this embodiment, the components and proportions of the garbage-derived fuel are: 70.0% (weight %) of domestic waste combustible components, 25.0% (weight %) of bituminous coal, 2.0% (weight %) of calcium oxide, industrial cornstarch 2.0% (weight %), sodium humate 1.0% (weight %). The drying temperature of the preparation step (2) is 250° C., the preparation step (4) is stored for 12 minutes, and the other steps are the same as in Example 1.

Embodiment 3

[0089] In this embodiment, the components and proportions of the refuse-derived fuel are: 74% (weight %) of domestic waste combustible components, 21.5% (weight %) of bituminous coal, 1.0% (weight %) of calcium oxide, industrial cornstarch 2.5% (weight %), sodium humate 1.0% (weight %). The drying temperature of the preparation step (2) is 300° C., the preparation step (4) is stored for 15 minutes, and the other steps are the same as in Example 1.

Abstract

The invention discloses a refuse-derived fuel based on combustible components of domestic refuse and a preparation method thereof, which are suitable for resource treatment of the domestic refuse. The refuse-derived fuel comprises the following components in percentage by weight: 65.0%-74.0% of the combustible components of the domestic refuse, 21.5%-30% of bituminous coal, 1.0%-2.5% of calcium oxide and 2.5%-3.5% of binding agent. The preparation method comprises the following steps of: firstly sorting the urban domestic refuse to obtain the combustible components; then drying and crushing the combustible components; then mixing various materials according to the mixture ratio and uniformly stirring; and finally performing extrusion forming. The refuse-derived fuel has the advantages of high calorific value, stable combustion, very low emission of dioxin, no pollution of heavy metals, and easiness in storage and transportation, and can realize reduction, harmlessness and resource utilization of the domestic refuse.

Description

technical field [0001] The invention relates to the technical fields of environmental protection and energy, in particular to a derived fuel based on combustible components of household garbage and a preparation method thereof, which is suitable for resource treatment of household garbage. technical background [0002] With the acceleration of my country's urbanization process and the improvement of people's living standards, the generation of urban domestic waste has increased sharply, and its impact on the environment has become greater and greater. Domestic waste disposal has become the focus of attention of the whole society. It is an urgent requirement from many aspects such as environment, economy and society to deal with municipal solid waste to make it reduce, harmless and recycle. [0003] The disposal methods of municipal solid waste in my country are mainly landfill, composting and incineration. The landfill method is to pile up domestic waste or directly bury it...
