90年代初,从法国KESTNER公司首次引进的5效管式降膜蒸发器在平果铝业公司拜尔法种分母液蒸发工艺中得到成功的应用。这种型式的蒸发器传热性能好,蒸发效率高,蒸发强度大、运行平稳、可靠,结构坚牢,使用寿命长(在平果铝已无故障运行7年)。但这种性能优越的蒸发器能否在国内开发、研制,以改变我国氧化铝生产蒸发工艺和设备长期落后的面貌;能否应用于国内联合法、烧结法氧
In the early 90s, the first 5-effect tubular falling film evaporator introduced from KESTNER in France was successfully applied in the Pingguo Aluminum Company Bayer process liquor evaporation. This type of evaporator heat transfer performance, high evaporation efficiency, evaporation intensity, smooth operation, reliable, solid structure, long service life (Pingguo aluminum has been trouble-free operation 7 years). However, this superior performance of the evaporator can be developed in China, development, in order to change the evaporation of alumina production technology and equipment in the face of long-term backwardness; can be applied to domestic joint law, sintering oxygen
