Product Description

Description

MVR Evaporation plant delivers substantial operational cost savings in areas with an ample supply of low-cost electrical energy.

Once an MVR evaporation plant is running, little or no additional steam is required. In the MVR evaporation plant, a centrifugal fan is used to recompress the vapour to a higher pressure, resulting in a temperature rise. This means that the recompressed vapour can be used as the evaporation plant heating medium, while the condensate is ideal for preheating of the feed product.

For low boiling point increases, a single-stage compressor can be used to fulfill the requirements of the design.

For high boiling point increases, we will provide two designs: multiple-stage compressors, single stage compressors combined with multiple-effect.

The MVR evaporation plant almost doesn't use steam, but electric energy is required as the main energy source.

The power consumption of the main motor of MVR is due to the heat exchange area and the evaporating temperature of the evaporation plant. The Heat exchange area is bigger, and as a result, power consumption is lower, but the investment in equipment is increased.

Evaporating temperature is higher and as a result, power consumption is lower, but fouling in the calandria is therefore increased; Evaporating temperature is lower and as a result, power consumption is higher.

MVR can be powered by an electric motor, the rotary speed of an MVR can be controlled by a frequency converter, and the rotary speed of an MVR may control the evaporation rate and final concentration of the MVR evaporation plant.

❓ Frequently Asked Questions
Q What is an MVR evaporation plant and how does it work?
An MVR (Mechanical Vapour Recompression) evaporation plant uses a centrifugal fan to recompress vapour to a higher pressure, causing a temperature rise. The recompressed vapour is then reused as the heating medium for the evaporation process, significantly reducing the need for external steam and lowering overall energy costs.
Q What are the main energy advantages of an MVR evaporation plant compared to a multiple-effect evaporation plant?
MVR evaporation plants use electric power as the primary energy source instead of steam. Based on a 50 T/h evaporation rate example, an MVR plant can save approximately 7,680,000 RMB per year compared to a 4-effect evaporation plant, consuming only 1,000 Kw/h versus 11 T/h of steam.
Q Which industries are best suited for MVR evaporation technology?
MVR evaporation plants are particularly well-suited for the food and beverages industry (milk, whey, sugar solutions), the chemical industry (aqueous solutions), the salt works industry (saline solutions), and environmental protection technology (concentration of wastewater).
Q How does the heat exchange area affect the power consumption of an MVR plant?
A larger heat exchange area results in lower power consumption for the MVR main motor, but it also increases the overall equipment investment cost. Conversely, a smaller heat exchange area reduces upfront costs but leads to higher ongoing power consumption. The optimal balance depends on energy pricing and operational requirements.
Q Can the evaporation rate of an MVR plant be controlled, and how?
Yes. The MVR is powered by an electric motor whose rotary speed can be precisely controlled by a frequency converter. By adjusting the rotary speed, operators can effectively control both the evaporation rate and the final concentration of the product in the MVR evaporation plant.
Q What key parameters are needed to select the right type of evaporation plant?
Selecting the right evaporation plant requires evaluating multiple factors including: capacity and operation data (evaporation rate, feed/final concentration), product properties (viscosity, foaming tendency, boiling point), utility requirements (steam pressure, cooling water temperature, energy unit prices), waste heat parameters, material selection criteria, and the preferred energy efficiency technology (MVR, TVR, multiple-effect, or waste heat evaporation).
