Abstract
The invention discloses a composite anti-corrosion structure for an annular titanium plate chimney of a thermal power plant and a coating process. A supporting rod of a supporting assembly is installed on one side of a supporting ring, a reinforcing screw is arranged on the supporting ring, a sealing layer is arranged on the outer side of the supporting ring, an annular titanium plate of the anti-corrosion assembly is fixedly connected to the supporting ring, a first hybrid polymerization layer and a resin layer are arranged on the two sides of the annular titanium plate, a sand blasting layer and a second hybrid polymerization layer are arranged on one side of the first hybrid polymerization layer, the first hybrid polymerization layer and the second hybrid polymerization layer can prevent high-temperature sulfuric acid liquid and smoke from alternately corroding the chimney, the sand blasting layer is arranged between the first hybrid polymerization layer and the second hybrid polymerization layer, the heat insulation effect can be further enhanced, meanwhile, infiltrated corrosive liquid can be adsorbed, the corrosion resistance is further enhanced, the supporting rod is arranged for mounting, the supporting ring is placed and pre-fixed through the reinforcing screw, and the annular titanium plate is placed, so that an old chimney is rapidly remade, and the remade efficiency is improved so as to reduce the production cost.
Description
technical field [0001] The invention relates to the field of anti-corrosion structures, in particular to a composite anti-corrosion structure and coating process for annular titanium plate chimneys of thermal power plants. Background technique [0002] my country's early thermal power plants did not add desulfurization devices, and a large number of reinforced concrete lining brick masonry were used. With the implementation of relevant domestic laws and regulations on environmental protection and the widespread application of wet desulfurization technology, it is imperative to carry out desulfurization transformation of these chimneys. However, wet desulfurization has brought serious corrosion problems in the chimney and flue. After desulfurization, no matter whether the flue gas heat exchanger (GGH) is installed or not, the flue gas temperature is lower than the acid dew point temperature. Although the content of sulfur dioxide and sulfur trioxide in the flue gas decreases...
