蒸发器是制冷四大件中很重要的一个部件,低温的冷凝“液”体通过蒸发器,与外界的空气进行热交换,“气”化吸热,达到制冷的效果。   蒸发就是用加热的方法,将含有不挥发性溶质的溶液加热至沸腾状况,使部分溶剂汽化并被移除,从而提高溶剂中溶质浓度的单元操作。工业生产中应用蒸发操作有以下几种场合: 1.浓缩稀溶液直接制取产品或将浓溶液再处理(如冷却结晶)制取固体产品,例如电解烧碱液的浓缩,食糖水溶液的浓缩及各种果汁的浓缩等 2.同时浓缩溶液和回收溶剂,例如有机磷农药苯溶液的浓缩脱苯,中药生产中酒精浸出液的蒸发等 3.为了获得纯净的溶剂,例如海水淡化等。 总之,在化学工业、食品工业、制药等工业中,蒸发操作被广泛应用。   1.按蒸发方式分: 自然蒸发:即溶液在低于沸点温度下蒸发,如海水晒盐,这种情况下,因溶剂仅在溶液表面汽化,溶剂汽化速率低。 沸腾蒸发:将溶液加热至沸点,使之在沸腾状态下蒸发。工业上的蒸发操作基本上皆是此类。 2.按加热方式分: 直接热源加热它是将燃料与空气混合,使其燃烧产生的高温火焰和烟气经喷嘴直接喷入被蒸发的溶液中来加热溶液、使溶剂汽化的蒸发过程。 间接热源加热 容器间壁传给被蒸发的溶液。即在间壁式换热器中进行的传热过程。 3.按操作压力分: 可分为常压、加压和减压(真空)蒸发操作。很显然,对于热敏性物料,如抗生素溶液、果汁等应在减压下进行。而高粘度物料就应采用加压高温热源加热(如导热油、熔盐等)进行蒸发 4.按效数分: 可分为单效与多效蒸发。若蒸发产生的二次蒸汽直接冷凝不再利用,称为单效蒸发。若将二次蒸汽作为下一效加热蒸汽,并将多个蒸发器串联,此蒸发过程即为多效蒸发。
