Embodiment 1

[0028] S10: Squeeze and dehydrate domestic waste: Squeeze domestic waste with extrusion equipment to reduce its water content to about 40%, and the extruded leachate will be treated and discharged after reaching the standard;

[0029] S11: Coarsely crush the domestic waste after the leachate is removed by squeezing, for example, into fragments with a particle size of less than 120mm;

[0030] S12: Carry out wind force coarse sorting (primary winnowing) to the coarsely crushed domestic waste, and divide it into light film material (i.e. the first light object) and heavy material (i.e. the first heaviest object); Fragments with a particle size of less than 20mm;

[0031] S13: Carry out fine crushing after a magnetic separation of heavy materials, and crush them into fragments with a particle size of less than 20mm;

[0032] S14: Dry the finely crushed heavy materials, and control the moisture content to less than 20%;

[0033] S15: performing secondary winnowing on the dried h...

Embodiment 2

[0041] S10: Squeeze and dehydrate domestic waste: Squeeze domestic waste with extrusion equipment to reduce its water content to about 40%, and the extruded leachate will be treated and discharged after reaching the standard;

[0042] S11: Coarsely crush the domestic waste after the leachate is removed by squeezing, for example, into fragments with a particle size of less than 120mm;

[0043] S12: Carry out rough wind separation (primary winnowing) to the coarsely crushed domestic waste, and divide it into light film materials and heavy materials; finely crush the light film materials into fragments with a particle size of less than 20mm;

[0044] S13: Carry out fine crushing after a magnetic separation of heavy materials, and crush them into fragments with a particle size of less than 20mm;

[0045] S14: Dry the finely crushed heavy materials, and control the moisture content to less than 20%;

[0046] S15: Perform secondary winnowing on the dried heavy materials to obtain f...

Abstract

The invention discloses a recycling method of combustible solid waste. The recycling method comprises the steps of preprocessing household garbage to obtain a first fine crushing material, preprocessing other combustible solid waste to obtain a second fine crushing material, mixing the first fine crushing material and the second fine crushing material with an auxiliary agent in a certain ratio to obtain a mixed material, and shaping the mixed material on a forming machine to produce a garbage deriving fuel in a preset shape. The recycling method of the combustible solid waste provided by the invention solves the problems that the cost is high, the investment of incineration equipment is large and the environmental pollution is serious when household garbage and other combustible solid waste are processed.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to a method for reusing combustible solid waste. Background technique [0002] At present, with the rapid development of the world economy, domestic garbage and other combustible solid waste (such as combustible hazardous waste, sludge from sewage treatment plants, industrial waste, etc.) have become obstacles to the stable and sustainable development of human society. Recycling and reducing the amount of these wastes is a difficult problem for all human beings. [0003] Among the solid wastes represented by domestic waste, most of them are combustible. Incineration and recovery of heat are recognized as the best method for reduction and resource disposal. At present, people have adopted a new type of waste disposal method The method is to make domestic waste into a sustainable renewable new energy product--refuse-derived fuel (RDF) after a series of pretreatments. The processed wa...
