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 th...

Abstract

A municipal household waste treating method and a device thereof are disclosed. Raw waste conveyed to a plant is subjected to pre-sorting through a screen for waste to sort out large bricks and stones and large and long organic matters, thus obtaining presorted waste. The sorted large bricks and stones are smashed and adopted as raw materials for manufacturing bricks. The large and long organic matters are smashed, then mixed with the presorted waste, conveyed to a rotary screen, and screened. Screen underflow materials are used for compost or adopted as raw materials for manufacturing bricks after the screen underflow materials are disinfected at high temperatures. Oversize products are dried, fed into a waste air classification apparatus, and subjected to air classification to obtain heavy materials, humified organic matters, unrecyclable combustible materials and light plastic. Metals are recovered from the heavy materials, batteries are sorted out from the heavy materials, and then the heavy materials are disinfected at high temperatures and smashed as raw materials for manufacturing bricks. The humified organic matters are used for compost or are directly incinerated in an incinerator. The unrecyclable combustible materials are smashed and are used for preparing waste-derivative fuels. The light plastic is used for preparing plastic reclaimed particles. The method and the device are advantaged by low investment, saved occupied space, a low running cost, no secondary pollution, thorough reduction, and the like.

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...
