Description

Technical Field

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

[0002] Landfill leachate is a highly concentrated organic wastewater formed by the water contained in the landfill's garbage, rainwater, snow, and other water that enters the landfill, minus the saturated water holding capacity of the garbage and overburden layers. Leachate also includes water that leaks from accumulated garbage destined for incineration. Because leachate contains numerous heavy pollutants, incineration is the current method of treatment for its purification.

[0003] A back-spray device is required in the process of collecting and incinerating landfill leachate. However, the existing back-spray device simply collects and stores the landfill leachate, and lacks the function of purifying the harmful gases generated by the landfill leachate. At the same time, since the landfill leachate is prone to solidification when it is left to accumulate, the existing back-spray device lacks measures to stir the landfill leachate and prevent it from solidifying.

[0004] Therefore, we propose a back-spray device for the combustion treatment of landfill leachate. Utility Model Content
