introduction
The solution in the natural circulation evaporator relies on the density difference of the material and liquid to circulate. In order to prevent scaling and crystallization, the heating tube should be operated in a fully immersed state. This kind of evaporator is suitable for the concentration of less corrosive and non-scaling solutions.
Application field
1. In order to evaporate products that are not sensitive to high temperatures, a large evaporation ratio is required.
2. For products that are prone to fouling, the apparent viscosity may decrease due to high speed.
3. The circulating evaporator with a divided boiling chamber and a top-mounted separator can be used as a high concentrator.
