Outline
Chloride ion is the key operating index in desulfurization system of power plants. Rapid and accurate monitoring of chloride ion content in desulfurization slurry is of great significance for anti-corrosion of desulfurization equipment, optimization and adjustment of operation process, as well as desulfurization waste water discharge and water saving. By studying the pretreatment method of sample, a high-efficiency composite medium filter is developed, and the method suitable for the desulfurization system sample pretreatment is studied, and the laboratory test is carried out. At the same time, by studying the principle of online measurement method of chloride ion in desulfurization system, a solid polymer membrane chloride selective electrode is developed, and on-line monitoring technology of chloride ion in desulfurization system of power plant is developed, and the accuracy test in laboratory and field industrial application test are carried out. The results show that, the technology can realize continuous and accurate online monitoring of chloride ion content in desulfurization slurry, reduce the workload of laboratory personnel greatly, and improve the accuracy of chloride ion measurement. It is of great significance to realize the economic and intelligent operation of desulfurization system equipment.
