Separation chamber of falling film evaporator is under the heat exchanger.
The black liquor enters preheating pipeline in the center of the heat exchanger through circulation pump, where black liquor recirculates, slightly being over-heated and evaporated a bit in upper area.
Distributing plate guarantees that the black liquor is uniformly distributed in the black liquor heating pipes.
The black liquor enters the inner wall of the heating pipe through the distributing plate with the liquid film being formed on the pipe wall and the second vapor being generated inside the pipe that accelerates the downward flowing of the liquid film and achieve uniform distribution.
The liquid-vapor mixture flows into the separation chamber at the bottom of the evaporator.
The vapor and black liquor are separated from each other before the vapor enters next effect evaporation through mist separator.
The liquid returns to the preheating zone of heating elements by recirculation pump to start next circle.
High heat transfer coefficient.
Relatively high pressure bearing capacity.
Advanced design of the distributing plate.
Vertical efficient mist separator.
The system has good operational flexibility; evaporator station can still run normally if the process condition changes significantly.
Low maintenance cost.
Self-stripping design for the effect evaporator.
