Problems solved by technology

[0002] At present, the treatment of municipal solid waste is facing serious social problems. Landfill treatment is unsustainable due to the lack of land resources and secondary pollution caused by landfill; the secondary pollution of the atmosphere caused by incineration is also unacceptable to the public; conventional gasification recycling Secondary high-temperature combustion restrains dioxins but increases the hazards of nitrogen oxides; plasma oxygen-free pyrolysis can be truly harmless, but the power consumption and garbage classification of plasma make it unacceptable in China and cannot be used

Abstract

The invention relates to a domestic garbage treatment method, a device and a mobile machinery shop, and aims to provide the domestic garbage treatment method to prevent generation of harmful substances to reduce environmental pollution. The domestic garbage treatment method comprises the garbage treatment steps of: drying-internal combustion cracking under a high-concentration oxygen environment-deacidification-filtration-secondary cracking-combustion; (a) drying: garbage is dried in a rotary drying kiln; (b) internal combustion cracking under high-concentration oxygen environment: the internal combustion cracking is performed for the garbage, dried by the rotary drying kiln, in an oxygen control cracking furnace under the high-concentration oxygen environment; (c) deacidification: cracking gas generated by the oxygen control cracking furnace is deacidified by a cracking gas purifier; (d) filtration: the deacidified cracking gas is filtered by a high-temperature membrane filter; (e) secondary cracking: the deacidified and filtered cracking gas is secondarily cracked in a high-temperature cracking tube; and (f) combustion: the secondarily cracked cracking gas is fed in a cracking gas combustion chamber for total combustion.

Description

technical field [0001] The invention relates to a domestic garbage treatment method, device and engineering vehicle. It is suitable for the field of green treatment of domestic waste. Background technique [0002] At present, the treatment of municipal solid waste is facing serious social problems. Landfill treatment is unsustainable due to the lack of land resources and secondary pollution caused by landfill; the secondary pollution of the atmosphere caused by incineration is also unacceptable to the public; conventional gasification recycling Secondary high-temperature combustion restrains dioxins but increases the hazards of nitrogen oxides; plasma oxygen-free pyrolysis can be truly harmless, but the power consumption and garbage classification of plasma make it unacceptable in China and cannot be used. Innovating and developing a new domestic waste treatment process with high reduction, high resource utilization, truly harmless, appropriate investment, and payback perio...
