Titanium falling film evaporator is an efficient single-pass non-circulating membrane evaporation equipment, which has the characteristics of high heat transfer efficiency, small temperature difference loss, short heating time, not easy to deteriorate, easy multi-effect operation, low energy consumption and small equipment size.
The main characteristic of this evaporator is that the solution is added from the top, falls film-like along the wall of the tube under the action of gravity, and in the process evaporates and thickens, obtaining a concentrate at the bottom of it. Since the film-forming mechanism is different from that of the rising film evaporator, the falling film evaporator can evaporate with a higher concentration and a higher viscosity (e.g., at 0.).05～0.45ns m2), heat-sensitive materials. However, because the liquid film is not easy to be evenly distributed in the tube, and the heat transfer coefficient is smaller than that of the rising film evaporator, it is still not suitable for materials that are easy to crystallize or scale.
In addition, the titanium falling film evaporator has the following advantages:
Strong adaptability: It can adapt to the evaporation and concentration of different materials, and is widely used in chemical, pharmaceutical, light industry, food and other fields.
High evaporation efficiency: due to the principle of falling film evaporation, the heat transfer and evaporation efficiency of the material can be improved.
High energy utilization: made of titanium, it has excellent corrosion resistance and high temperature performance, which can improve energy utilization.
Small size: Compared with other types of evaporators, titanium falling film evaporators are smaller in size and can save space.
Easy maintenance: The structure of the titanium falling film evaporator is simple, easy to maintain, and the operating cost is reduced.
In general, titanium falling film evaporator is a kind of efficient, energy-saving and environmentally friendly evaporation equipment, which has been widely used in chemical, pharmaceutical, light industry, food and other fields.
