Usually the cylindrical filter bag is hung vertically in the dust collector. The fabric and design of the dust bag should strive for high-efficiency filtration, easy dust removal and durability.
[0003] At present, incineration of hazardous waste is the most promising method for hazardous waste treatment. It mainly works through preheating and high temperature to degrade hazardous waste to a certain extent. However, it will produce certain exhaust gases during combustion, such as nitrogen oxides, sulfur oxides, dioxins, smoke and exhaust gases containing heavy metal components. Most of these exhaust gases are treated with bag filters.
