Description

Technical Field

[0001] The utility model relates to the technical field of leachate treatment, in particular to a leachate concentrated liquid back-spray furnace equipment. Background Art

[0002] Garbage leachate refers to a high-concentration organic wastewater formed by the water contained in the garbage itself in the landfill, the rain and snow water entering the landfill, and other water, minus the saturated water holding capacity of the garbage and the covering soil layer, and passing through the garbage layer and the covering soil layer. In order to ensure the stability of garbage treatment, the leachate needs to be sprayed back into the boiler through the back-spraying equipment. Since the leachate contains solid particles, most of the time, the permeate is filtered through the filter device before back-spraying. However, after the filter device is used for a long time, it is easy to cause the filter device to be blocked, which is inconvenient to clean, affecting the filtering effect of the leachate. Therefore, we have launched a new leachate concentrate back-spray furnace equipment. Utility Model Content
