摘要（英）：

The invention discloses a composite anti-corrosion structure for the inner wall of a desulfurization tower and application thereof, belonging to the technical field of corrosion prevention for desulfurization towers. The composite anti-corrosion structure for the inner wall of the desulfurization tower sequentially comprises a polyurethane modified fluorosilicone resin sprayed layer, a polyurethane modified fluorosilicone resin glass flake sprayed layer and a polyurethane modified fluorosilicone resin carbon fiber sprayed layer from the steel inner wall of the desulfurization tower to the outside. The composite anti-corrosion structure is of a three-layer overlapped structure composed of the polyurethane modified fluorosilicone resin sprayed layer, the polyurethane modified fluorosiliconeresin glass flake sprayed layer and the polyurethane modified fluorosilicone resin carbon fiber sprayed layer. A unique construction structure is adopted in the invention, and different corrosion prevention methods are adopted according to the abrasion and corrosion resistance degrees of all parts of the desulfurization tower, so the corrosion prevention and service life of the desulfurization tower are improved; and the anti-corrosion structure is simple in construction method and low in construction cost, and has great economic benefits and social benefits.
