[0002] The composite anti-corrosion structure of the chimney inner wall usually refers to an anti-corrosion system that combines a variety of anti-corrosion materials and technologies on the inner wall of the chimney. It is used to cope with complex working conditions such as high temperature, high pressure, and corrosive media, so as to extend the service life of the chimney and ensure its safe and stable operation.

[0003] The composite anti-corrosion structure currently used on the inner wall of the chimney has not yet achieved ideal results in terms of corrosion resistance and high temperature resistance. This structure may experience problems such as decreased material performance and shortened service life under long-term exposure to high temperature and corrosive gases.

[0004] Therefore, it is necessary to develop a composite anti-corrosion structure for the inner wall of a chimney containing a fluorine rubber surface layer, which can improve the corrosion resistance and high temperature resistance and extend the service life of the chimney. Utility Model Content

[0011] 1. The utility model can improve the protective performance of the composite anti-corrosion structure of the inner wall of the chimney with the fluorine-containing rubber surface layer installed. The fluorine-containing rubber surface layer is the outermost layer of the composite anti-corrosion structure and is made of fluorine-containing rubber material. The fluorine-containing rubber has excellent chemical resistance, especially in terms of acid resistance, alkali resistance, heat resistance, etc., and can effectively resist the erosion of the acid gas, corrosive steam and other media discharged from the chimney. The topcoat layer is used to protect the fluorine-containing rubber surface layer, increase the aesthetics and weather resistance. The topcoat is usually a high-performance coating that is resistant to ultraviolet rays and aging, thereby making the composite anti-corrosion structure of the inner wall of the chimney with the fluorine-containing rubber surface layer have the characteristics of aging resistance, high temperature resistance and corrosion resistance, thereby extending the service life of the chimney;

[0012] 2. The utility model has a water spray head installed, and the input end of the water trough is connected with the external delivery pipeline. The external cleaning agent can flow into the inside of the water trough through the pipeline.
