MVR falling film vacuum evaporator for wastewater treatment , chemicals treatment
MVR tubular falling film evaporator
Working principle and characteristics:
After preheating by the preheater, the material is added from the upper tube box of the heat exchanger. The material is distributed into each heat exchange tube through the liquid distributor, and a uniform liquid film is formed along the inner wall of the heat exchange tube. The liquid film in the tube is heated by the heating steam on the shell side during the downward flow process, boiling and evaporating while flowing downward. At the bottom of the heat exchange tube, the material becomes concentrated liquid and secondary steam. The concentrated liquid falls into the lower pipe box, and the secondary steam enters the gas-liquid separator. In the gas-liquid separator, the liquid droplets entrained by the secondary steam are removed, and the pure secondary evaporation is transported from the separator to the compressor. The compressor compresses the secondary steam and sends it to the shell side of the heat exchanger as heating steam for the heat source of the evaporator. The continuous evaporation process is realized.
The characteristics of MVR falling film evaporator are as follows
1. The solution flows in a film shape in a one-way evaporator with high heat transfer coefficient;
2. It covers a small area;
3. For heat sensitive material, it can be made into one pass material, the material retention time is short, and it is not easy to cause material deterioration;
4. Low energy consumption;
5. Small liquid retention, easy to realize automatic cleaning.
MVR falling film evaporation system is suitable for the concentration of materials and pre concentration of salt crystallization. It is suitable for evaporating materials without particles, not easy to scale and with low viscosity, especially for heat sensitive materials.
Benefits
