How to prevent fouling in falling film evaporators

Pre treatment: Proper pre-treatment of raw materials to remove suspended solids and large particle impurities.

Choose appropriate materials: Use anti pollution and anti-corrosion materials to reduce the possibility of dirt adhesion.

Control operating conditions: Optimize evaporation temperature and pressure to avoid the generation of dirt in high temperature and high concentration environments.

Regular cleaning: Develop a regular cleaning plan, use chemical cleaning agents to remove dirt, and keep the equipment clean.

Reasonable flow rate design: Ensure moderate liquid flow rate to avoid retention and sedimentation.

Use additives: Add anti fouling agents as needed to reduce the formation of dirt.

Through these measures, the accumulation of dirt in the falling film evaporator can be effectively reduced, and the service life of the equipment can be extended.
