[0002] Sludge refers to the sediment, particulate matter and floating matter produced when wastewater is treated by physical, chemical, physicochemical and biological methods. Sludge must be treated before agricultural use and landfill so that the treated sludge can meet the requirements of stability and harmlessness. When treating sludge, after the sludge is dried by sludge drying equipment, its structure becomes loose and it is easy to become sandy and cause dust problems. The escape of dust causes harmful substances to be distributed in the air, turning part of the air into harmful gases, so the harmful gases need to be treated.

[0003] The patent with the patent authorization announcement number CN219111115U discloses a sludge treatment dust removal device, including a dust removal box, a collection box is fixedly provided on the upper surface of the bottom plate of the dust removal box, and a sewage filter is fixedly provided on one side of the inner end of the collection box.
