Detailed Product Description: | Desulfurization equipment used more often on early foreign chimney has applications are now less used. No domestic chimney applications. 2.3.6 anti-corrosion coating layer material pouring acid + 1) anti-corrosion coating layer, acid pouring steel inner cylinder surface material before brushing anticorrosive coating layer plus pour pouring acid material, within the general configuration pouring acid material layer and the inner cylinder with steel link steel mesh. Anticorrosive coating layer is OM Ⅰ type anti-corrosion coatings. Pouring acid resistant materials generally have acid resistant concrete, mortar acid potassium silicate layer 2) anti-corrosion coating layer, acid corrosion material pouring this scenario, construction conditions corrosion lining of poor quality control difficult. And high anti-corrosion lining design requirements, can not produce fine cracks penetrate chimney flue to prevent steel corrosion within the cylinder. Multi-tubular steel inner cylinder chimneys, steel corrosion within the cylinder liner pouring investment scheme lowest multi-tubular steel inner cylinder chimney program. Due to the inevitable anti-corrosion lining smoke corrosion, such steel chimney need regular repair and maintenance of the inner cylinder. According to Japan's experience, generally more than ten years on the need for re-corrosion lining repair and construction. 3) anti-corrosion coating layer, acid pouring steel construction material lining the inner cylinder by 10 ~ 18mm thickness of steel plate welded into a curved back. Outside steel inner tube around 6m intervals along the height of each set up a steel ring (T-beam or stiffening angle). Has a steel inner tube stabilization device in maintenance platform and lifting platform at elevation, in order to ensure the overall stability of the transverse steel inner cylinder. Steel inner cylinder * corrosion resistant steel sulfuric acid, in the design of the steel structure of the inner cylinder is calculated, reserved corrosion affluence 2mm thickness. Pouring steel inner cylinder surface to a thickness of 60mm corrosion-resistant coating of concrete. Cement concrete coating of silicon material for potassium mortar, concrete coating with a steel mesh, and the inner cylinder with steel anchor bar links. Steel inner tube diagram below. 4) domestic Beilun Port plant engineering applications # 1, # 2 (600MW) units (not desulfurization) using acid-resistant material, the new power plant in Hancheng second 600MW unit (FGD) within the ceramic paste using a mortar layer of acid potassium silicate acid board. This chimney decay practices in Japan there is no tower tower and rack-steel chimney more often. According to the "Eleventh Five-Year Plan" requirements, the 2010 national emissions of major pollutants than the "fifth" period by 10%, corresponding to the total SO2 emissions need to be cut by more than 10%. To achieve this goal, China's coal-fired units to be supporting the installation of flue gas desulphurization facilities. Currently in China coal-fired units desulfurization basically using limestone, gypsum desulfurization technology, because the technology of its carrier is water and limestone flue gas desulfurization temperature drops about 45 degrees Celsius, and contains a lot of water vapor and SO2, flue and internal chimney condensate, the main component of the ice condensation is H2SO4, HC1, and other corrosive gas liquids, the formation of corrosion on the chimney and flue, so coal-fired units in the desulfurization chimney and chimney corrosion is the most important issues to be addressed formation . |
