CE Multiple Effect Evaporation System , Multiple Effect Evaporator Wastewater Treatment

Multi Effect evaporation Treatment for Lithium Battery Industry Wastewater Sodium Chloride + Lithium Chloride

Multiple Effect Evaporation

Multiple Effect Evaporation remains one of the popular methods used for the concentration of aqueous solutions.

The chief factor influencing the economy of an evaporator system is the number of effects.

By increasing the number of effects we can increase the economy of an evaporator system.

The first effect of a multiple effect evaporator is the effect to which the raw steam is fed.

Vapors obtained from first effect act as a heating medium for another effect.

TVR or MVR is used in Multiple Effect Evaporators to use the dead vapors.

For an evaporator maximum boiling temp is 80℃ in first stage and 40℃ in the last.

Advantages

- Utilize the secondary steam reasonably, to save more energy and be more economical.

- Multiple process designs, suitable for different materials.

- Less investment compared with MVR evaporation system.

Applications

Food & beverage

Chemical

Pharmaceutical

Pesticide

Printing & dyeing

Metallurgy

Fermentation

Tobacco

What are the of Features and Advantages of the MEE system to be used in for the wastewater treatment plant?

According to the characteristics of the material and the size of the evaporation capacity, it can be designed as a single-effect or multi-effect evaporation unit, with flexible equipment combination and large operating space;

The heat transfer coefficient of the multi-effect evaporation system is relatively high, the heating time of the material is short, and the evaporation temperature is low, which can effectively reduce equipment corrosion.

The multi-effect steaming system makes full use of the latent heat of the secondary steam of the material to minimize heat emission and reduce the consumption of raw steam.

The heat exchange tube of the multi-effect evaporation system is not easy to foul, with high heat transfer efficiency, large operating flexibility, reliable operation and long operating cycle.

Characteristics

Reduction of the use of live steam by using vapour steams from the previous stage as heating medium for the following stage.

Flexible partial load operation is possible.

Suitable for various applications.
