    • A thin film evaporator having a plurality of effects arranged in a vertical array and connected in a series relationship. A portion of the liquid fed over heat exchange tubes as a thin film is vaporized to condense vapor passed therethrough. The unevaporated feed liquid is passed through successive effects and the vapor generated in each effect is employed as the heating vapor for the next effect. The heat exchange tubes of at least one of the initial effects is arranged generally vertically and those in the balance of the effects are arranged generally horizontally and extend radially with their outlet ends facing condensate collecting chambers disposed within a central core. Feed water preheaters extend vertically through a plurality of collecting chambers with a feed liquid take-off for each phase.
    • 一种薄膜蒸发器,其具有以垂直阵列排列并以串联方式连接的多种效应。 通过热交换管作为薄膜供给的液体的一部分被蒸发以冷凝通过其中的蒸气。 未蒸发的进料液体通过连续的作用,并且在每个效应中产生的蒸汽用作加热蒸气用于下一个效果。 初始效应中的至少一个的热交换管大致垂直布置,并且效果平衡的热交换管大致水平地布置并且径向延伸,其出口端面对设置在中心芯内的冷凝物收集室。 给水预热器通过多个收集室垂直延伸,每个相的进料液体起飞。
