Abstract
The invention discloses a composite anti-corrosion structure and a coating process for an annular titanium plate chimney in a thermal power plant. The support rod of the support assembly is installed on one side of the support ring, the reinforcement screws are arranged on the support ring, and the sealing layer is arranged on the support ring. On the outside of the ring, the annular titanium plate of the anticorrosion component is fixedly connected to the support ring, the first hybrid polymer layer and the resin layer are arranged on both sides of the annular titanium plate, and the sandblasting layer and the second hybrid polymer layer are arranged on the first hybrid side of the aggregated layer. The first hybrid polymer layer and the second hybrid polymer layer can prevent the alternating corrosion of the chimney by high-temperature sulfuric acid liquid and flue gas, and the sandblasting layer in the middle can further strengthen the heat insulation effect, and at the same time can prevent the infiltrated corrosion liquid Adsorption, to further enhance the anti-corrosion ability; set up support rods for installation, place support rings and pre-fix them with reinforcement screws, and put ring-shaped titanium plates to quickly carry out the transformation of old chimneys, improve transformation efficiency, and reduce production costs.
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...
