China Suppliers Factory for External Heating Two Effect Vacuum Evaporator - Efficient Solution Evaporation Technology
Main principles
The mechanical steam re compression MVR evaporator utilizes the secondary steam generated in the evaporator. After being compressed by the compressor, the pressure and temperature increase, and the enthalpy increases. It is then sent to the heating chamber of the evaporator as heating steam to maintain the boiling state of the feed liquid, while the heating steam itself condenses into water. In this way, the steam that was originally to be discarded is fully utilized, recovering moisture and improving thermal efficiency. The economic efficiency of steam generation is equivalent to 30 times that of multi effect evaporation, reducing the demand for external heating and cooling resources, energy consumption, and pollution.
Main features
1. MVR energy-saving evaporator technology is currently one of the most advanced evaporator technologies internationally, which only requires a very small amount of steam (a small amount of steam is needed during startup, and steam is almost no longer needed during normal operation), greatly reducing enterprise operating costs and reducing environmental pollution.
2. Due to the use of a compressor to provide heat source, the temperature difference is much smaller compared to traditional evaporators, which can achieve mild evaporation, greatly improve product quality, and reduce scaling.
3. No condenser or only a small area of condenser is required, the structure and process are very simple, fully automatic operation, continuous operation, safe and reliable.
4. The equipment is equipped with CIP cleaning pipelines, which can achieve on-site cleaning. The entire equipment is easy to operate and has no dead corners.
5. The MVR evaporator is used to evaporate materials at low temperatures (evaporation temperature of 40 ℃ -100 ℃). The material liquid is uniform, does not run, is not prone to coking, and the heating denaturation of the material is small.
Frequently Asked Questions (FAQ)
What is the core working principle of an MVR evaporator? ▼
The MVR (Mechanical Vapor Recompression) evaporator reuses the secondary steam it generates. By compressing this steam with a compressor, its pressure, temperature, and enthalpy are increased. It is then redirected back to the heating chamber to maintain the boiling state of the feed liquid, significantly enhancing thermal efficiency.
How energy-efficient is MVR compared to traditional multi-effect evaporation? ▼
MVR technology is highly cost-effective. Its steam generation economic efficiency is approximately 30 times that of traditional multi-effect evaporation. It only requires a small amount of steam during the initial startup process and almost none during normal continuous operation.
Does the MVR system require a condenser? ▼
Generally, no condenser is required, or only a very small condenser area is needed. This makes the system structure and process design exceptionally simple, reliable, and capable of fully automatic continuous operation.
Can the MVR evaporator handle heat-sensitive materials? ▼
Yes, the MVR evaporator is excellent for heat-sensitive materials. It operates at low temperatures (ranging from 40 ℃ to 100 ℃), which ensures the material remains uniform, prevents running or coking, and minimizes any thermal denaturation.
How is the MVR evaporator cleaned and maintained? ▼
The system is integrated with CIP (Clean-in-Place) cleaning pipelines, enabling convenient on-site cleaning. The design ensures there are no dead corners, making operation and maintenance highly straightforward and hygienic.
