The principle of MVR evaporator is to use a high-efficiency steam compressor to compress and evaporate the secondary steam generated by evaporation, convert electrical energy into heat energy, increase the enthalpy of the secondary steam, and heat the secondary steam by injecting it into the evaporation chamber for heating, in order to achieve the purpose of recycling the existing heat energy of the secondary steam without the need for external steam generation, relying on the self circulation of the evaporator to achieve evaporation and concentration. Control system temperature, pressure, motor speed, and maintain system evaporation balance through PLC microcontroller configuration and other forms. In theory, using an MVR evaporator saves over 80% of energy, over 90% of condensate water, and reduces footprint by over 50% compared to traditional evaporators.
Main principle: Mechanical vapor recompression (MVR) evaporator utilizes the secondary steam generated in the evaporator, which is compressed by a compressor to increase pressure, temperature, and enthalpy, and then sent to the heating chamber of the evaporator as heating steam to maintain the boiling state of the feed liquid. The heating steam itself condenses into water. In this way, the steam that was originally intended to be discarded is fully utilized, latent heat is recovered, and thermal efficiency is improved. The economy of steam production is equivalent to 30 effects of multi effect evaporation, reducing the demand for external heating and cooling resources, energy consumption, and pollution.
Scope of application: Mechanical vapor recompression (MVR) evaporator, suitable for low-temperature concentration in industries such as milk, glucose, organic acids, VC, xylose, pharmaceuticals, chemical engineering, biotechnology, environmental engineering, waste liquid recovery, papermaking, salt production, etc.
System composition: It consists of a heater, separator, compressor, vacuum pump, circulation pump, operating platform, electrical instrument control cabinet, valves, pipelines and other systems, with a very simple structure.
Main features:
1. MVR energy-saving evaporation technology is currently the most advanced evaporation technology internationally, requiring only a very small amount of steam (a small amount of steam is needed when starting up, and almost no steam is needed during normal operation), greatly reducing the operating costs of enterprises and minimizing environmental pollution.
2. Due to the use of a compressor as a heat source, the temperature difference is much smaller compared to traditional evaporators, which can achieve mild evaporation, greatly improving product quality and reducing scaling.
3. No need for a condenser or only a very small area of condenser, 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. This evaporator is used to evaporate materials at low temperatures (evaporation temperature of 40 ℃ -100 ℃), with uniform material distribution, no material leakage, and low coking. The material undergoes minimal heating deformation.
MVR evaporators are applied in milk, glucose, starch, monosodium glutamate, xylose, pharmaceuticals, chemical engineering, biotechnology, environmental engineering, waste liquid recovery, papermaking, salt production, food, seawater desalination, and sewage treatment.
