Evaporator plays an important role in industry, the two main types of MVR evaporator and multi-effect evaporator, so WHAT is the difference between MVR evaporator and multi-effect evaporator?

This is currently for MVR evaporator and multi-effect evaporator consultation more problems, often owners in the purchase of evaporator will be compared to MVR evaporator and multi-effect evaporator, need to understand the difference between MVR evaporator and multi-effect evaporator.

MVR evaporator is the secondary steam mechanical compression evaporator, is the use of steam compressor will evaporate out of the secondary steam recompression temperature rise, and then sent to the evaporation heater for repeated use. MVR evaporator basically does not need to consume raw steam, but only consumes part of the electric energy, which mainly depends on the temperature rise required by the secondary steam and the efficiency of the steam compressor.

Multi-effect evaporator is designed by using the temperature difference from the first effect to the final effect to design the evaporator for repeated use of secondary steam. Generally, the evaporation temperature of the first effect evaporation is controlled by the thermal sensitivity temperature of the material, and the temperature of the final effect secondary steam is determined by the local altitude and the selection of the vacuum unit. The consumption of raw steam is inversely proportional to the amount of leector.

MVR evaporators and the difference between the multiple effect evaporator is heating steam consumption of the main difference, the difference between the rate of cooling water, heat input, cover an area of an area the size of the difference, the difference between operating system, the difference between the comprehensive energy saving effect MVR evaporators is better than that of multiple effect evaporator, but with the MVR evaporators price is higher than the rate of multiple effect evaporator.
