Description

Technical Field

[0001] The utility model relates to the technical field of garbage treatment, in particular to a combustion device for garbage treatment residues. Background Art

[0002] Waste incineration is an environmentally friendly treatment method. Through high-temperature oxidation reactions, waste is converted into residues or molten solid substances to achieve the purpose of volume reduction and harmlessness. At the same time, waste incineration can also recover heat and realize waste resource utilization. It has significant effects in reducing volume, saving land, eliminating pathogens, and converting toxic and harmful substances. Therefore, waste incineration has become one of the main methods of urban waste treatment.

[0003] After searching, a utility model patent with Chinese patent publication number CN218033150U discloses a garbage treatment incineration device. The garbage treatment incineration device in the utility model patent is provided with an enclosure on the top of the incinerator body, and a treatment liquid is injected into the liquid tank enclosed by the enclosure, and the smoke gas generated by the combustion is discharged into the treatment liquid for treatment. However, on the one hand, the smoke gas generated by the combustion also has high temperature characteristics. If it is directly introduced into the liquid tank in the incineration device without pre-cooling treatment, it may cause the liquid tank structure to suddenly alternate between hot and cold and there is a risk of boiling and bursting. On the other hand, the substances produced by the combustion of garbage not only contain a large amount of particulate dust, but also include some sulfur oxides and nitrogen oxides in the gas products. Gas components, wherein sulfur oxides and nitrogen oxides will produce sulfuric acid and nitric acid substances after being directly introduced into the treatment liquid, which are extremely corrosive and will also affect the stability of the liquid tank and the incinerator structure. Therefore, the garbage treatment incineration device needs to be further improved in the purification treatment structure of the combustion products, and therefore a combustion device for garbage treatment residues is proposed.
