烧碱蒸发系统的技术改造

The technical innovation of caustic soda evaporation system

分析了烧碱蒸发系统运行中存在的各种问题:生蒸汽压力不稳定,蒸发料液预热温度偏低,末效真空度偏低,蒸发系统结盐严重,成品碱冷却能力不足。技术改造后,运行稳定。

Each kind of problems existing in the operation of caustic soda evaporation system was analyzed, such as unstable raw steam pressure,low preheating temperature of evaporation stream,low vaccum in the end - effect evaporator, serious salt scale formation in the evaporation system, insufficient cooling capacity for final caustic soda. After technical innovation, the system keeps running stably.
