What issues should be considered for multi effect evaporators

  What issues should be considered for a multi effect evaporator? 1. Corrosive solutions. When evaporating corrosive solutions, the heating tube should be made of special materials or lined with corrosion-resistant materials on the inner wall. If the solution is not afraid of contamination, a direct heating evaporator can also be used. 2. The viscosity of the solution and the range of viscosity changes during evaporation are the primary factors to consider when selecting a solution. 3. For solutions with crystal precipitation during evaporation, external heat evaporators or forced circulation evaporators should be used. 4. For the thermal stability of solutions that are prone to polymerization and scaling due to prolonged heating, evaporators with low material retention and short residence time should be used. 5. The processing capacity of the solution is also a factor
