Evaporator System:
Falling film tube evaporation system is to add the feed liquid from the upper tube box of the heating chamber of the falling film evaporator, and distribute it evenly into each heat exchange tube through the liquid distribution and film forming device, and form a uniform film under the action of gravity and vacuum induction and airflow. Flow from top to bottom. During the flow, it is heated and vaporized by the heating medium on the shell side, and the generated steam and the liquid phase enter the separation chamber of the evaporator together. 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. During the operation of the falling film evaporator, the residence time of the material is very short, so the heat transfer efficiency is very high.
The type of plate evaporator is a thin-film evaporator, and the material residence time is short, so it is especially suitable for the evaporation and concentration of heat-sensitive materials. The plate evaporator system has a compact structure and a small footprint. In particular, its height is lower than that of general evaporators, so it does not require a high workshop and can be installed in ordinary single-story buildings. In addition, the evaporator equipment is easy to disassemble and assemble, easy to clean, and suitable for the evaporation of high-viscosity materials. Under the same evaporation conditions, the equipment investment cost is lower than other evaporators of the same type.
MVR evaporator is an advanced energy-saving technology that utilizes the latent heat of condensation of the secondary steam generated in the process of evaporation and concentration, thereby reducing the demand for external energy in the process of evaporation and concentration. The basic principle of MVR evaporation technology is to make the evaporator generate secondary steam through external raw steam, and then through the compression and heating effect of the compressor, the pressure and saturation of the secondary steam are increased, and the secondary steam with increased enthalpy is sent to the evaporation system. , used to supplement or completely replace raw steam, and the operating cost is mainly the consumption of the compressor.
