Introduction to technology
Natural circulation mechanical vapor compression vacuum evaporators work with electrical energy and are easy to use and maintain.
The distillate production capacity of this product line ranges from 10-120 L/h. These systems are an excellent investment due to their combination of distillate quality, high technology and robustness.
Forced circulation mechanical vapor compression vacuum evaporators obtain high quality water by separating it from the effluent with a high concentration of contaminants by the application of thermal energy. Forced circulation evaporators work under vacuum conditions, reduce the boiling temperature and so reduce energy consumption.
Vacuum evaporators concentrate a waste effluent as many times as desired, resulting in zero discharge if necessary. This technology can treat complex wastewater when other more conventional techniques are not effective or viable.
Functioning/operation of technology
The operation of the mechanical vapor compression vacuum evaporators is based on the recovery of the condensation heat from the distillate as a source of heat to evaporate the feed.
In these systems, the process starts with the external energy supply to the evaporator to start the evaporation process. The operation of the mechanical vapor compression vacuum evaporators is based on the recovery of the condensation heat from the distillate as a source of heat to evaporate the feed. The steam produced is extracted and compressed by a volumetric compressor with the intention of increasing its temperature. This superheated steam is then returned to the evaporator as a heating fluid. Once the cycle has begun, no more external heat input is required, as the mechanical compression of the steam provides enough heat to maintain the evaporation of the liquid. Upon passing through the exchanger of the evaporator itself, this compressed, and therefore superheated, vapor has two effects: (1) it heats the liquid to be evaporated and (2) it condenses, thereby reducing the need for a refrigeration fluid.
The main advantage of mechanical vapor compression vacuum evaporators lies in the fact that the energy consumption of the volumetric compressor is lower than the cost of producing steam for multi-effect evaporation systems. However, the volume to be evaporated must be high enough so that the saving generated compensates for the investment in the volumetric compressor.
Natural circulation mechanical vapor compression vacuum compressors are an excellent investment due to their combination of distillate quality, high technology and robustness. The distillate production capacity of this product line ranges from 10 to 120 L/h.
Natural circulation evaporators can be of two types, with horizontal or vertical tubes, which in turn can be upstream or downstream.
