Background
The circulating cooling water system is an important component of a thermal power plant, and the cooling tower rows of most domestic power plants are manually controlled. Chlorine radicals are generally measured by a chemical method, and when the concentration ratio of circulating water is higher than a control value, personnel in a main control room are informed to open a blow-down valve of a cooling tower to blow down. Due to the long period of manual sampling and measuring, the delay of the opening and closing of the pollution discharge valve and the like, the concentration ratio fluctuation of the circulating water is large, and the control value cannot be stably controlled. The concentration ratio of the circulating water is too low, the make-up water amount and the discharge capacity of the circulating water are too large, and water and chemicals are wasted. The concentration ratio of the circulating water is too high, so that the hardness and alkalinity of the circulating cooling water are too high, the scaling tendency of the water is increased, and the safe operation of a power plant is seriously threatened.
