摘  要:
The fouling and blocking of split-phase groove and process pipe in wet-process phosphoric acid purification is very frequent, affecting the production running smoothly. The key point and scaling mechanism of cleaning technics of wet-process purification phosphoric acid plant is introduced. The technology plan and process for cleaning fouling are put forward. After new program is implemented, the system operating rate is increased to more than 90%, the cleaning cost is saved about 2.5 million RMB Yuan per year.
