[0002] In the garbage incineration process, the temperature of the smoke will gradually decrease with the flow and the processing process. When the temperature of the smoke decreases to a certain extent, part of the harmful substances in it may combine with the condensed water or the moisture in the air to form acidic corrosive liquid. These acidic corrosive liquids have a strong corrosive effect on the internal structure and materials of the dust remover.

[0003] In order to reduce the impact of the acidic corrosive liquid on the dust remover, an anticorrosive coating or surface treatment is often applied to the inner surface of the dust remover.
