Description

Technical Field

[0001] The utility model relates to a garbage treatment device, in particular to a small garbage incineration device. Background Art

[0002] The common garbage treatment method is to simply classify and then pile and bury for treatment. Although the burying cost is relatively low, it will occupy more land and may cause secondary environmental pollution such as leachate. The choice of this treatment method will be affected by factors such as geographical environment, garbage composition, and economic development level, which is not conducive to environmental governance, the development of environmental protection work, and wastes financial and material resources. Large garbage incineration treatment production lines are not applicable to small-scale treatment. Based on this, it is necessary to design a more practical and smaller garbage incineration treatment device. Summary of the Utility Model
