Problems solved by technology

[0004] In my country, urban living garbage is mostly treated by landfill, incineration, composting, etc. These traditional treatment methods have brought us secondary pollution and wasted a lot of renewable resources.
These simple treatment processes are also an important reason for the inability to reduce waste

Embodiment Construction

[0015] Embodiments of the invention:

[0016] 1. Squeeze the garbage, concentrate the leaching solution in the storage tank, and then meet the secondary discharge standard after treatment, and carbonize the sludge.

[0017] 2. The garbage is crushed, squeezed, dried, and subjected to primary and secondary crushing, and the metals are classified and recycled after magnetic separation.

[0018] 3. After the crushed garbage is selected by wind and screened, the organic matter and plastic are separated from the inorganic solid waste; the organic matter and plastic enter the kiln for dry distillation, and the inorganic matter enters the brick workshop.

[0019] 4. Dry distillation, dehydration, and deoxygenation of the dried garbage and shale bricks made of additives in the yin kiln; the temperature of the yang kiln is at 400-1000 ℃, and the garbage bricks are rapidly thermally decomposed and carbonized due to the action of additives ; The organic matter in the garbage is decompos...

Abstract

The invention discloses a low-temperature dry distillation and high-temperature quick thermal decomposition treatment process method for municipal domestic garbage, and belongs to the technical field of treatment and utilization of the municipal domestic garbage. The method uses flammable gas generated in the high-temperature decomposition process to pretreat and dry the garbage and to heat a thermal decomposition furnace, gets rid of the garbage and changes waste material into things of value without exterior energy consumption, and achieves cyclic utilization of the garbage regeneration energy. The successful research and development of the yin and yang cyclic high-temperature thermal decomposition furnace solves key technology problem of garbage high temperature thermal decomposition technology and device. An organic garbage pressing molding technology effectively guarantees garbage batch treatment and heat value of regeneration carbon. The high-temperature thermal decomposition in a close anoxia condition in the garbage treatment process and use of additive restrain and eliminate the generation of the dioxin, and no dust or exhaust gas is directly discharged, so that a secondary pollution problem is solved. A garbage volume reduction rate and a resource use ratio are maximized.

Description

technical field [0001] The invention belongs to the technical field of municipal solid waste treatment, and is an advanced comprehensive system process for solid waste treatment, especially a low-temperature dry distillation high-temperature rapid thermal decomposition treatment process for municipal solid waste. And high-temperature rapid thermal decomposition technology, to achieve no incineration, no secondary pollution, energy regeneration and utilization process. Background technique [0002] With the rapid development of my country's economic construction and urban construction, the urban framework is getting bigger and bigger, the urban population is increasing, and the amount of domestic garbage is also increasing. Domestic garbage has become one of the environmental problems we are facing that need to be solved urgently. The annual growth rate of garbage in the world is 8.42%, while the growth rate of garbage in China reaches more than 10%. China alone produces near...
