Embodiment 1

[0026] Raw garbage enters the factory and is weighed and measured, then unloaded into the garbage sieve hopper, roughed by garbage sieve, and the oversize masonry and long organic matter with a particle size greater than 300mm are sorted out, and the undersize is pre-separated Choose trash.

[0027] The long organic matter with a particle size greater than 300mm is sheared and crushed until the particle size is not greater than 100mm, and then returns to the conveyor belt with permanent magnet rollers, and enters the trommel screen together with the pre-sorted waste under the screen for screening.

[0028] The undersize material with a particle size less than 20mm obtained from the drum sieve is collected for use, and the oversize material over 20mm is loaded by a tunnel car, and enters the inner cavity 6 of the tunnel oven from the feed port 1, and the temperature is controlled at 250-300 The material is dried at ℃, discharged from the discharge port 7, and then enters the wi...

Abstract

The invention discloses a processing method of municipal solid wastes and a device thereof, the method comprises the following steps: presorting native incoming wastes by a waste screen, presorting large-piece masonry and too large organic matter to obtain presorted wastes; smashing the presorted large-piece masonry into brick making raw material, mixing the smashed too large organic matter and the presorted wastes, feeding the mixture into a drum screen to screen, with the undersized waste used for composting or is disinfected at high temperature into brick making raw material, feeding the dried oversized material into a garbage winnowing device, winnowing heavy material, humified organic matter, non-recyclable combustible material and light plastic. Metal is recovered from the heavy material and the heavy material is disinfected at high temperature after being picked out of the battery, smashed into brick making raw material; the humified organic matter is used for composting and is burned directly in an incinerator; non-recyclable combustible material is smashed to prepare refuse derived fuel; light plastic is used for preparing regeneration particles. The invention has the advantages of small investment, small floor area, low operation cost, no secondary pollution and thorough reduction.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and relates to a treatment method and a treatment device for municipal domestic garbage. Background technique [0002] At present, the country and governments at all levels have listed the comprehensive treatment of urban domestic waste as a key project for social sustainable development, but the treatment technology of urban solid waste is correspondingly lagging behind. Garbage disposal is an emerging industry. Since there is no authoritative organization and unified standards to judge and certify, the existing technologies and equipment used by factories in various places have different defects due to the complex characteristics of municipal solid waste and the differences in geographical and climatic conditions in various places. The extrusion dehydration described in the Chinese patent application 200610040458.5 domestic waste comprehensive treatment process will cause pulping of p...
