Falling film evaporator material

The falling film evaporator system consists of various effect evaporators, various effect separators, condensers, hot press pumps, vacuum and drainage systems, various utility liquid transfer pumps, operating systems, electrical instrument control cabinets, valves, pipelines and other systems. Because falling film evaporator is widely used in industrial, chemical, biochemical and other fields, the materials of the whole equipment should be heat-resisting, pressure-resisting, corrosion-resisting and high-quality. There are several required materials : SUS3045; 3166L; titanium alloy; Q2335B and so on.

 Falling film evaporator characteristics

The characteristics of falling film evaporator are as follows:

1. Since the solution flows in a single-pass type evaporator, the heat transfer coefficient is high, the residence time is short, and the material is not easily deteriorated. It is suitable for processing heat sensitive materials.

2. The liquid of the falling film evaporator is added from the top of the evaporator, and descends along the wall of the tube under the action of gravity. Sample will be evaporated and concentrated during this process, and a concentrated liquid is obtained at the bottom. The falling film evaporator can evaporate materials with higher concentration and higher viscosity.

3. Falling film evaporator is suitable for evaporation and concentration of foaming materials.
