Evaporators play an important role in industry. The two main types are MVR evaporator and multi-effect evaporator. What is the difference between MVR evaporator and multi-effect evaporator? Let me introduce the difference between the two evaporators.
For MVR evaporator and multi-effect evaporator, this is the most frequently asked question at present. Owners often compare MVR evaporator and multi-effect evaporator when purchasing evaporator. They need to understand the difference between MVR evaporator and multi-effect evaporator. difference.
Today we will discuss with you the difference between MVR evaporator and multi-effect evaporator. Before understanding the difference between them, let's first understand MVR evaporator and multi-effect evaporator.
MVR evaporator is a mechanical compression evaporator for secondary steam. It uses a steam compressor to recompress the evaporated secondary steam to increase its temperature, and then sends it to the evaporation heater for reuse. MVR evaporator basically does not need to consume raw steam, but only consumes a part of electric energy. Electric energy consumption mainly depends on the temperature rise required for the secondary steam and the efficiency of the steam compressor.
Multi-effect evaporator is an evaporator that uses the temperature difference from the first effect to the last effect to design the secondary steam for repeated use. Generally, the evaporation temperature of the first effect evaporation is controlled by the thermal sensitive temperature of the material, while the temperature of the final effect auxiliary steam is determined by the local height and the selection of the vacuum device. The consumption of raw steam is inversely proportional to the number of effectors.
The difference between MVR evaporator and multi-effect evaporator is mainly the difference in heating steam consumption, cooling water treatment capacity, heat input, floor area, operating system and comprehensive energy. The energy-saving effect of MVR evaporator is better than that of multi-effect evaporator, but the price of MVR evaporator with the same processing capacity is higher than that of multi-effect evaporator.
