[0010] 1. The utility model facilitates the protection layer structure to prevent local corrosion of the flue through the installed No. 1 Velcro and No. 2 Velcro, and directly replaces the damaged anti-corrosion structure. When the No. 2 anti-corrosion layer is damaged, pulling the heat insulation layer will drive the No. 2 Velcro to separate from the No. 1 Velcro, and then the heat insulation layer and the No. 2 anti-corrosion layer can be disassembled. After the replaced heat insulation layer is moved and aligned with the support layer, the heat insulation layer is pushed to make the No. 1 Velcro and the No. 2 Velcro adsorbed. At the same time, the heat insulation layer is limited by the limiting component, and then the position of the replaced No. 2 anti-corrosion layer is limited. After the No. 2 anti-corrosion layer is damaged, the anti-corrosion function of the protection layer structure to prevent local corrosion of the flue is affected. The damaged part can be quickly repaired, which improves the protection performance and construction efficiency.

[0011] 2. The utility model effectively improves the anti-corrosion effect by installing the No. 1 anti-corrosion layer and the No. 2 anti-corrosion layer. The No. 2 anti-corrosion layer has nano-ceramic coating, which can withstand high temperatures up to degrees Celsius. It also has good acid and alkali corrosion resistance, high hardness and resistance to dust erosion, as well as excellent adhesion and temperature change resistance.
