  • 蒸发器是制冷四大件中很重要的一个部

    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。工业应用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...

  • 升膜蒸发器的特点以及产品的构成

          升膜式蒸发器特点: 这种蒸发器需要精心设计与操作,即加热管内的二次蒸汽应具有较高速度,并获较高的传热系数,使料液一次通过加热管即达到预定的浓缩要求。通常,常压下,管上端出口处速度以保持20~50m/s为宜,减压操作时,速度可达100~160m/s。升膜蒸发器适宜处理蒸发量较大、热敏性、粘度不大及易起沫的溶液,但不适于高粘度、有晶体析出和易结垢的溶液。相对于降膜蒸发器装机功率比较小。      升膜蒸发器的构成是液体根据虹吸泵的原理进入加热管加热,流入到分离器后液体与蒸汽分离开来,通过循环管...
