How to prevent scaling in the evaporation chamber or delay its formation
Thread Content
Our factory is equipped with single-effect evaporation units that use forced circulation, but we have been facing the problem of scaling in the evaporation chamber. Salt accumulates on the walls of this chamber and is difficult to remove. The problem worsens when, after a while, these salt deposits break off and block the heating chamber, forcing us to stop the operation in order to clean the chamber. Is there any way to prevent scaling in the evaporation chamber? It may help to slow down scaling.

Another option is that, if it has no impact on your product, you can consider using EDI, ion exchange, or mixed-bed processes to treat the product first.
I don’t know what substance is evaporating; add some polymerization inhibitors, or use vacuum to lower the temperature through negative pressure.
I’m not sure what the purpose of your evaporation process is? If it’s just a concentration issue, then some way needs to be found to find a cleaning agent or a solution. If it is an evaporation crystallization process aimed at producing a solid product, then adjustments should be made to the evaporation crystallization process in order to extend the tank cycling time
I wonder if you’ve solved that problem?
What are the components causing scaling in your evaporation chamber?
