Detailed Product Description: | Wet flue gas desulfurization characteristics and corrosion 1, wet flue gas desulphurization wet flue gas desulfurization characteristics of humidity, low temperature, prone to condensation. After the condensation of water vapor in the flue gas, mainly dependent on the chimney wall flow to the discharge port desulfurization system specifically set discharged waste pool. The flue gas desulfurization process also contains fluoride and chloride and other corrosive materials, to form a high corrosion strength, permeability, low humidity and difficult to guard against acid corrosion. High sulfur dioxide removal efficiency of wet FGD technology, but the main component of the corrosion caused by flue gas sulfur trioxide, low removal efficiency. Fired, about 0.5% to 2% of the sulfur produced during combustion of sulfur trioxide, in wet desulfurization unit is 20% of the sulfur trioxide prolapse, remaining sulfur trioxide smoke aerosol is brought out, he chimney corrosion is enormous. Therefore, after the flue gas desulfurization, chimney corrosion risks have not been eliminated. On the contrary, after the flue gas desulfurization environment (low temperature, high humidity) so that corrosion situation further. 2, wet desulfurization of flue gas desulfurization corrosion corrosion due to my short history of the country, a special survey research data less corrosion, less experience, GB 50051--2002 "chimney design" is not based on the dry flue gas desulfurization division corrosion grade of chimney corrosion treatment is based is based on the dry flue gas corrosion levels, while the wet desulfurization chimney corrosion treatment after the design is no clear explanation. Therefore, after the corrosive flue gas desulfurization chimney structure analysis, the main information and practices from abroad. |
