China Suppliers MVR Evaporation Plant - Energy-Efficient Factory Solution for Food, Chemicals, and Wastewater
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.
✅ Low specific energy consumption.
✅ Gentle evaporation of the product due to low temperature differences largely increases product quality, decreases fouling.
✅ Short residence times of the product, as a single-effect system is most often used.
✅ Only a small area condenser, requiring little cooling water.
✅ High availability of the plants due to the simplicity of the process.
✅ Excellent partial load behaviour.
✅ Low specific operating costs.
