I would appreciate your advice: Is the material choice for our wet electrostatic precipitators appropriate?

I think the material is good; when you have money, you can be indulgent.

Lead-plastic electrostatic dust removal can be considered, as well as duplex steel

The poster mentioned that the flue gas from the power plant is treated using wet flue gas desulfurization, which is the most common method for desulfurizing power plant flue gas both domestically and internationally. But precisely because this method is the most common, and environmental regulations were merely nominal in previous years, neither the designers of wet flue gas desulfurization systems in power plants nor the equipment suppliers invested much effort in researching this technology. The works of genuine FGD designers for flue gas desulfurization technologies in power plants both domestically and internationally result in treated gas exiting the FGD unit with very low levels of sulfur, dust, and liquid droplets. The basic components of a real power plant flue gas FGD tower should include a slurry spraying zone, a high-efficiency dynamic blade demisting zone, and a high-efficiency dynamic blade washing zone. On the other hand, in many domestic power plants over the past few years, the flue gas desulfurization systems have been deceiving the plant owners: the slurry spraying systems were manufactured with shoddy materials, resulting not only in low desulfurization efficiency but also in the airflow carrying acidic droplets and dust downstream ； The demisting system should have utilized a patented, proprietary dynamic design platform to develop an efficient dynamic demisting blade system; however, neither the designers nor the manufacturers possessed such a design platform. As a result, the demisting system was created by imitating the appearance of others’ patented, efficient dynamic blade assemblies, using the common \"louver\" design, without realizing that the internal dynamic flow channel structure of efficient dynamic demisting blades is completely different from that of louver designs! The internal structure determines performance! Regarding the determination of the gas-phase net flow area, since there is no patented, proprietary kinetic precision shooting system platform, the values are determined based on experience and personal understanding ； What is not known is that dynamic separation technology requires precise control of the gas flow velocity; if the velocity is too low, quantitative coalescence separation cannot be achieved, while if it is too high, the separated liquid will be carried back into the gas phase, resulting in suboptimal demisting separation effects. Furthermore, some desulfurization units do not have a washing area for the blade assembly; as a result, scale accumulates on the surface of the blades over time, leading to an increase in pressure drop and a reduction in the efficiency of separation. If the separation efficiency of the existing FGD unit in the power plant is not satisfactory, the designer, the original equipment supplier, or the owner needs to carry out technical modifications by installing electrostatic demisting and dust removal equipment after the existing FGD unit. But is static dust and foam removal equipment sufficient on its own? Many power plants also have electrostatic dust and foam removal equipment; during trial operations, it has been found that this type of equipment is not adaptable to changes in operating conditions, resulting in poor separation efficiency. Those familiar with electrostatic dust and foam removal technologies know that such equipment has strict requirements regarding the types of particles carried by the airflow, as well as stringent constraints on the size distribution of the dust and liquid droplets present in that airflow ； Otherwise, the separation efficiency is not satisfactory. Regarding the use of electrostatic dust removal technology, if it can be combined with dynamic and efficient gas-liquid separation techniques such as the vane-type high-efficiency dynamic gas-liquid separation method, as well as dynamic and efficient gas-solid separation techniques like multi-factor swirl separator systems, then high-efficiency dynamic separators with low operating costs can be used to remove the majority of the liquid droplets and particulates contained in the airflow in advance ； Let the electrostatic dust removal equipment capture the remaining, very small droplets and particulates. This dust removal technology, which combines a \"high-efficiency kinetic separator\" with electrostatic dust removal, ensures smoother system operation, lower operational and maintenance costs, and better exhaust gas parameters.
