Design and application of climbing film evaporator 升膜蒸发器的设计与应用
Application situation of plate-type climbing film evaporator in ionic membrane caustic soda evaporation system and the characteristics of evaporation units were introduced in particular. 重点介绍了板式升膜蒸发器在离子膜烧碱蒸发系统中的应用情况及蒸发装置的特点。
The technical process design parameters and structure design scheme of climbing film evaporator which was adopted in the industry of producing caustic alkali from urao for the first time were introduced. 首次将升膜蒸发器应用于天然碱制烧碱行业。介绍了该设备的工艺设计参数及结构设计方案。
The result indicated that the heat exchange area of preheater and Compressor power increases, and the heat exchange area of climbing film evaporator, forced circulation ( type) evaporator and COP reduced as the evaporation temperature raised. 结果表明:随蒸发温度升高,预热器换热面积、压缩机功率增大,升膜蒸发器换热面积、强制循环蒸发器换热面积、制热能效比COP减小。
