Product Details

Main features:

The feed liquid enters through the bottom of the evaporator after preheating, enters the heating tube and quickly vaporizes after boiling, and the generated steam rises at a high speed in the heating tube. The solution is driven by the rising steam, rises along the tube wall into a film, and continues to evaporate in the process, and the mixture of steam and liquid is separated in the separator, and the liquid is discharged at the bottom of the separator. The secondary steam enters the MVR compressor, and after being compressed by the compressor, the pressure rises and the temperature rises, and the material that needs to be evaporated is heated as a new heat source. MVR falling film evaporator is mainly composed of preheater, separator, vacuum system, MVR compressor, control system and cleaning system.

Advantages of MVR rising film evaporator:

1. The residence time of the material liquid in the tube is only a few seconds to several seconds. The time is short, and the amount of liquid is small, especially suitable for the concentration of heat sensitive liquid.
2. The heat transfer coefficient of the rising film evaporator is higher than that of the ordinary falling film evaporator, and the heat transfer effect is good.
3. the concentration ratio can not be too high, such as the concentration ratio is too high, because the material liquid is less, the pipe wall wetting is poor, the formation of solid solute adhesion on the pipe wall "dry pipe" phenomenon, not only increases the thermal resistance, but also blocks the heating pipe.
4. simple structure, easy maintenance, can be operated under pressure, normal pressure and pressure.

Main application of MVR rising film evaporator:

It is widely used for evaporation and concentration of water or organic solvent solution in pharmaceutical, food, chemical, light industry and other industries, and can be widely used for waste liquid treatment in the above industries, especially for heat-sensitive materials. The equipment is continuously operated under vacuum and low temperature conditions, with high evaporation capacity, energy saving, low operating costs, and can ensure the material invariance during evaporation.
