Forced Circulation MVR Evaporator System for thermal and vacuum evaporation and crystallization
The MVR evaporator uses the secondary steam generated in the evaporator to be mechanically compressed by the compressor, the pressure is increased, the heat is increased, and then the heat exchanger is condensed to fully utilize the latent heat of the steam, except for the start-up operation, the entire evaporation process, the theory There is no need for a single steam, so that the steam that was originally discarded is fully utilized, the latent heat is recovered and the thermal efficiency is improved, and the economy is equivalent to the 30 effect of multi-effect evaporation.
1)MVR energy-saving evaporator technology is currently the most advanced evaporator technology in the world, only a very small amount of raw steam is needed (a small amount of steam is required when starting up, Steam is almost no longer needed in normal operation, which greatly reduces the operating costs of the company and reduces environmental pollution.
2)because the heat source provided by the compressor is much smaller than the conventional evaporator, the temperature difference can be achieved, the product can be greatly improved, Reduce fouling.
3)no condenser or only a small area of condenser, the structure and process is very simple, fully automatic operation, continuous operation, safe and reliable.
4)The equipment is equipped with CIP cleaning pipeline, which can realize local cleaning. The whole set of equipment is easy to operate, no dead angle, high degree of automation and stable operation.
5)The evaporator is evaporated by the material at a low temperature (evaporation temperature 50 ℃ - 95 ℃) and is not easy to generate foam. The liquid is uniform and does not run material, not easy to coke, the material heat denaturation is minimal.
6)Although the initial investment quota is high, the return on investment of most projects is generally 1.5 to 2 years, and the maximum is no more than three years.
||High energy consumption, about 1.5 tons of steam is required to evaporate one ton of water
||Energy consumption is high. One ton of steam is theoretically required to save one ton of steam.
||Compared with the increase in efficiency, the energy consumption is correspondingly reduced.
||The traditional multi-effect evaporator is based on one more effect, but requires high-pressure steam to drive
||the most energy-efficient evaporator technology; 20kw/h-70kw/h power consumption
|Impact on product quality
||Evaporation products have a long residence time, which seriously affects product quality and color.
||The residence time is short but the temperature difference is high; easy to scale; less impact on product quality.
||Longer residence time, higher temperature difference; easy to scale; Smaller impact on product quality
||Short residence time, less impact on product quality,
||short residence time, low temperature difference evaporation; not easy to scale; minimal impact on product quality
