The flowing medium of this project is the saturated wet flue gas after the alkaline washing tower (wet air and acid or alkaline water vapor), including the flue gas from yellow phosphorus tail gas combustion and phosphorus distillation flue gas. The normal flue gas temperature ranges from 40 to 55℃, and the pH value is between 4 and 10. The flue gas contains acidic substances and dust such as fluorides, sulfur and phosphorus, or excess alkaline washing liquid, presenting strong corrosiveness. The treatment capacity of the wet electrostatic precipitator is 185,000 m³/h, with the normal inlet flue gas temperature of 40–55℃. When the inlet dust content is ≤ 60 mg/m³, the outlet dust concentration is required to be ≤ 15 mg/m³.
