Other Features
Working Principle
Two stages take the feed from liquid inlet to separated concentrate and vapor, in a single continuous pass.
-
Under differential pressure, the liquid feed is drawn into the tubular evaporator and evenly distributed into the tube bundle through an integrated liquid distributor.
-
The liquid flows downward along the heated tube walls under gravity, forming a thin and continuously renewed film that maximizes heat transfer surface contact.
-
Heat is transferred through the tube wall from the heating medium, rapidly vaporizing the volatile componentsduring the short residence time while minimizing thermal exposure.
-
The concentrated liquid is collected in the buffer tank, while entrained droplets are separated by the cyclone gas-liquid separator through gravity and centrifugal separation before the vapor enters the condenser.
