MVR Evaporator
Working Principle
Mechanical Vapor Recompression (MVR) evaporators utilize the secondary steam generated within the evaporator. This steam is compressed by a compressor, which increases its pressure, temperature, and enthalpy. The compressed steam is then directed to the heating section of the evaporator to serve as the heating medium, maintaining the feed liquid in a boiling state, while the heating steam itself condenses into water. This process allows for the full utilization of steam that would otherwise be wasted, recovering its latent heat and enhancing thermal efficiency. The economy of the primary steam is equivalent to that of a 30-effect multi-effect evaporation system, significantly reducing the demand for external heating/cooling resources, lowering energy consumption, and minimizing pollution.
Special Characteristics
MVR energy-saving evaporation technology represents the current international standard for advanced evaporator systems. It requires only a minimal amount of primary steam (a small quantity is needed for start-up, with almost none required during normal operation), drastically reducing operational costs and environmental impact for enterprises.
As the heat source is provided by a compressor, the temperature difference is much smaller compared to traditional evaporators. This enables gentle evaporation, greatly improving product quality and reducing scaling.
It requires no condenser or only a very small condenser, featuring a simple structure and process flow. The system offers fully automated operation, capable of continuous and safe, reliable running.
The implementation of this equipment relies on extensive experience, precise design techniques, and cutting-edge automation technology.
