Evaporation Process Of Materials In Vertical Mechanical Stirring Film Evaporator

- Oct 17, 2017 -

Because the conventional evaporation heat exchanger equipment can not adapt to the evaporation and reaction of certain materials, especially heat-sensitive materials, viscous materials and the trend of foaming materials. In this case, it is suggested that the use of thin film evaporator to replace, it is possible to obtain a good evaporation effect.

The film evaporator has been introduced at home and abroad, but there are some differences between them, but in any case, the products are in the direction of large-scale, serialization and generalization. Not only that, but also in distillation, separation, concentration, extraction, deodorization, degassing, reaction and other processes to play a role, making the film evaporator is widely used in petrochemical, food, biochemistry, medicine and other industries.

It is understood that the basic structure of the thin film evaporator is composed of two parts, driven and evaporated, to the more commonly used vertical mechanical stirring film evaporator, for example, when the material from the feed into the evaporator, through the central axis of the cloth plate through centrifugal force are all cloth on the cylinder wall.

And then through the scraper to stir, drive, dispersing a series of functions, so that the material can be in the film evaporator evaporation cylinder heating the inner wall to form a uniform liquid film; As the liquid film will continue to absorb the heating medium in the jacket to supply evaporation surface, the rapid evaporation of material on its surface, so that the film layer after evaporation will be diluted.
