Falling Film Evaporator Plate Type Mvr Evaporator for Ethanol Evaporation
Falling film evaporation is to add the material liquid from the upper tube box of the heating chamber of the falling film evaporator, and distribute it evenly into the heat exchange tubes through the liquid distribution and film forming device. Under the action of gravity, vacuum induction and air flow, it becomes a uniform film. Flow from top to bottom. During the flow process, it is heated and vaporized by the heating medium in the shell side. The generated steam and liquid phase enter the separation chamber of the evaporator. After the vapor and liquid are fully separated, the steam enters the condenser for condensation (single-effect operation) or enters the next-effect evaporator as The medium is heated to achieve multi-effect operation, and the liquid phase is discharged from the separation chamber.

The MVR evaporator energy saving technology is the most advanced international technology of evaporator, only need few live steam (When start evaporator need few live steam, during normal running almost no need live steam), which greatly reduce business operating costs, reduce environmental pollution.
Due to adopt compressor supply heat source, there is little temperature difference which compared with traditional evaporator, and can achieve moderate evaporation,greatly improved product quality and reduce fouling.
No need condenser or only need small size condenser, the structure and process are quite simple, it can be full automatic operation, continuous running, safety and reliable.
This evaporator internal system equipped with CIP clean pipeline, which can achieve clean in place, easy to operate and without dead angle.
Liquid material can be evaporated under low temperature (50-100℃) in this evaporator, the liquid material is uniform and without running material, not easy coking, material heating denaturation is minimal.
Due to use of 100% recycling secondary steam latent heat, completely avoid the use of live steam, so greatly reduced steam consumption.
For heat-sensitive materials can be used with vacuum pump, which can be done in close to absolute pressure under vacuum, so as to realize low temperature evaporation, the minimum evaporation temperature can be 50 ℃.
Simple process control and automation——Because of the small amount of fluid retention, the falling film evaporator can be change according to different vacuum degree/feeding capacity/ concentration/ temperature , which is the basic conditions for stable quality of products.
The handling capacity can be up to 100T/h, with advantages such as small floor space, compact structure, stable operation and so on.
