Selection of Ceramic Valves in Power Plant Desulphurization Process

With the development of electricity, the air pollution in our country has been serious in recent years. As an important pollutant of sulfur dioxide, more than 60% comes from the emission of industrial fumes. According to relevant information, excessive sulfur dioxide 600 million people. With the perfection and strengthening of environmental protection standards in our country and the continual improvement of national environmental protection awareness, our country formulates relevant policies, and desulfurization must be carried out for some industrial flue gas emissions. The power station desulfurization system, one of the most important parts, I am afraid that the number of valves. The desulfurization station requirements are generally higher. Not only to meet the harsh conditions of high wear and corrosion, but also be able to withstand chloride, oxide, acid and alkali. How to choose the correct type of ceramic valve, power station flue gas desulfurization process is the key. General ceramic valves in the power plant desulfurization system is mainly used for absorption tower (PH value, level, discharge, gypsum slurry flow), limestone slurry supply (limestone slurry tank level, limestone slurry concentration), gypsum dehydration (filtrate tank water level) Process water and rinse (demister rinse, absorber slurry pipe flushing, process tank level) system control. And for this condition of the ceramic valve to a few ceramic ball valve.
