Description

Technical Field

[0001] The utility model relates to the technical field of garbage treatment, in particular to an environmentally friendly garbage incineration tail gas treatment device. Background Art

[0002] Domestic waste treatment refers specifically to the treatment of solid waste generated by daily life or activities that provide services for daily life, as well as solid waste that is deemed to be domestic waste by laws and regulations. It includes source reduction, cleaning, classified collection, storage, transportation, treatment, disposal and related management activities of domestic waste. When treating waste, it is usually incinerated.

[0003] At present, when garbage is incinerated, the sorted domestic garbage is generally placed in an incinerator for incineration. A large amount of exhaust gas will be generated during the incineration of garbage. The incinerator cannot treat the exhaust gas generated by the incineration when it is working.
