Introduction to the Features of MVR Steam Compressors
Release date:
2021-01-20
MVR stands for Mechanical Vapor Recompression. MVR is an energy-saving technology that reuses the secondary steam generated during the evaporation process to reduce the demand for external energy sources. The principle behind the MVR vapor compressor is that it compresses the secondary steam produced by the evaporator using a compressor, thereby increasing its pressure and temperature. As a result, the enthalpy of the steam also rises. This steam with increased enthalpy is then sent to the heating chamber of the evaporator, where it heats and evaporates the feed liquid. The MVR vapor compressor’s chamber itself serves as a source of heating steam, keeping the material in a boiling state, while the heating steam itself condenses into water. In this way, the latent heat contained in the secondary steam can be fully utilized, achieving the goal of energy conservation.

The principle behind the MVR vapor compressor is that the compressor compresses the secondary steam produced by the evaporator, thereby increasing its pressure and temperature. As a result, the enthalpy of the steam also rises, and this steam—now carrying increased enthalpy—is sent to the heating chamber of the evaporator to heat and evaporate the feed liquid. The MVR vapor compressor’s chamber itself serves as a source of heating steam, keeping the material in a boiling state, while the heating steam itself condenses into water. In this way, the latent heat contained in the secondary steam can be fully utilized, achieving the goal of energy conservation. The following section will provide further details. MVR steam compressor The characteristic.
1. The MVR steam compressor is constructed with a heavy-duty frame and an integral cast iron body, precision-machined by CNC, and features precise mounting and positioning links.
2. All components are machined in-house. They are processed and integrated using machining centers, ensuring more precise time tolerances. The positions of the bearings and the wall panels are treated as a whole to guarantee accurate bearing alignment.
3. The impeller of the MVR steam compressor is made of high-grade cast iron (or duplex stainless steel, titanium) and is manufactured using high-precision four-axis machining. It features accurate shape and dimensions and is permanently fixed to a steel shaft.
4. The bearings are imported. Under continuous operation of the MVR steam compressor, their service life is approximately 26,000 hours. Proper maintenance can further extend their service life.
5. The precision timing synchronous gears, made of alloy steel, are permanently fixed to the shaft and are lubricated by splashing gear oil from the oil tank onto the synchronous gears.
6. The steam compressor employs a special dual-mechanical seal system, enabling completely leak-free operation of the steam compressor.
7. Lubrication is provided by a dual-head lubricating oil tank, which significantly improves the service life of the steam compressor’s bearings and gears and avoids the drawbacks of conventional models that rely on grease lubrication.
8. This material is made of either solid cast iron (duplex stainless steel or titanium). The internal cavity of the cast-iron compressor is coated with a special layer. While the corrosion resistance of this special coating is slightly lower than that of the original titanium material, its resistance to cavitation, water erosion, and corrosion is higher than that of titanium.
9. MVR steam compressor Temperature control is achieved by using spray water from the inlet nozzle to regulate the temperature required at the outlet.
10. All steam compressor motors are equipped with variable-frequency motors, allowing the processing capacity to be adjusted according to actual needs.
