Second hand material 316 dual effect 5-ton falling film evaporatorFalling film evaporation is the process of adding material liquid from the heating chamber of the falling film evaporator into the tube box, and evenly distributing it into each heat exchange tube through the liquid distribution and film formation device. Under the influence of gravity, vacuum induction, and airflow, it flows in a uniform film shape from top to bottom. During the flow process, the steam generated by the shell side heating medium vaporizes and enters the separation chamber of the evaporator together with the liquid phase. The steam and liquid are fully separated, and the steam enters the condenser for condensation (single effect operation) or enters the next effect evaporator as the heating medium, thus achieving multi effect operation. The liquid phase is discharged from the separation chamber. Evaporation is a unit operation for concentrating solutions, usually solvents can evaporate, while most solutes have vapor pressures approaching zero and cannot evaporate. Under boiling conditions, the solution is vaporized to remove some of the solvent and make it concentratedThe process of shrinking is called evaporation. In most cases, the evaporator uses water vapor as the heating medium (usually referred to as heating steam, primary steam, or fresh steam), and indirectly transfers heat to the solution through the metal wall. After the solution is heated, the solvent boils and vaporizes, and the resulting steam (mostly also water vapor) is called secondary steam.
