The present invention pertains to a drying system and drying method for organic waste selected from municipal solid waste, which improve functionality and usability and reduce drying time by drying organic waste efficiently, wherein the drying system comprises: a sun-drying bay (10) in which organic waste selected from municipal solid waste is fermented and dried; a supply unit (20) for selectively supplying a predetermined amount of organic waste to the sun-drying bay (10); a stirring unit (30) for stirring the organic waste disposed in the sun-drying bay (10); a blowing unit (40) for providing air to the organic waste disposed in the sun-drying bay (10); a transfer unit (50) for transferring the organic waste fermented and dried in the sun-drying bay (10); and a drying unit (60) for drying, once more, the organic waste transferred by the transfer unit (50).
F26B 17/02 - Machines or apparatus for drying materials in loose, plastic, or fluidised form, e.g. granules, staple fibres, with progressive movement with movement performed by belts carrying the materialsMachines or apparatus for drying materials in loose, plastic, or fluidised form, e.g. granules, staple fibres, with progressive movement with movement performed by belts propelling the materials over stationary surfaces
F26B 23/10 - Heating arrangements using tubes or passages containing heated fluids

The present invention is a technique that relates to a compressing, cutting/crushing, and sorting method and sorting system for turning combustible waste into fuel, the method comprising: collecting household waste discharged from homes and combustible waste (waste vinyl, waste synthetic resin, etc.) which is generated from housing land development businesses, main SOC businesses, or the like and is buried in a large-scale unsanitary landfill or is buried in an unsanitary landfill and has been illegally buried in the past, and naturally drying the collected waste in a drying place; primarily, in a reduction and sorting step which is a pre-treatment step, sorting foreign substances, such as soil, stone, wood, scrap metal, or the like, attached to and mixed with the combustible waste, and transporting same to a combustible-to-fuel sorting device; compressing bulky waste which is harmful into small shapes, and then cutting and crushing same by using a compressing and cutting/crushing device which reduces the waste by precisely sorting and separating metals as well as foreign substances; crushing the waste into a size suitable for use as a fuel, sorting high-quality combustible waste that meets specifications of Fluff SRF (non-formed solid fuel), and at the same time, wrapping the combustible waste by means of a wrapping device so as to allow the combustible waste to be used finally as a fuel.
B03C 1/02 - Magnetic separation acting directly on the substance being separated
B07B 13/08 - Grading or sorting solid materials by dry methods, not otherwise provided forSorting articles otherwise than by indirectly controlled devices according to weight
F26B 15/18 - Machines or apparatus for drying objects with progressive movementMachines or apparatus with progressive movement for drying batches of material in compact form with movement in a path composed of one or more straight lines, e.g. compound the lines being all horizontal or slightly inclined the objects or batches of materials being carried by endless belts
F26B 3/04 - Drying solid materials or objects by processes involving the application of heat by convection, i.e. heat being conveyed from a heat source to the materials or objects to be dried by a gas or vapour, e.g. air the gas or vapour circulating over, or surrounding, the materials or objects to be dried
F26B 21/00 - Arrangements for supplying or controlling air or gases for drying solid materials or objects
F26B 21/02 - Circulating air or gases in closed cycles, e.g. wholly within the drying enclosure
B65B 11/02 - Wrapping articles or quantities of material, without changing their position during the wrapping operation, e.g. in moulds with hinged folders
B65B 13/02 - Applying and securing binding material around articles or groups of articles, e.g. using strings, wires, strips, bands or tapes
The present invention relates to a system for treating combustible waste and, specifically, the purpose of the present invention is to provide a combustible waste treatment system, which collects a gas to be generated by pyrolyzing solid refuse fuel (SRF) made from combustible waste, so as to finally produce dimethyl ether (DME). The combustible waste treatment system of the present invention can comprise: a solid fuelization unit for making SRF from combustible waste; a gas production unit for producing a synthesis gas by pyrolyzing the SRF; a methanol production unit for producing methanol from the synthesis gas; and a DME production unit for producing DME from the methanol.
