MVR evaporator is a special evaporator equipment. At present, it has been widely used in many fields. When using it, you should not only understand its operation method, but also understand its performance. MVR evaporator technology can reuse the secondary steam energy generated by the system itself, thus reducing the demand for external energy. Its principle is to compress the cooled secondary steam in the traditional evaporator, and the steam temperature will rise accordingly to realize the transformation from low temperature and low pressure steam to high temperature and high pressure steam, which can be used as a heat source for heating the raw liquid to realize steam recovery. The purpose of volume compression is achieved by mechanical compressor, so it is called mechanical steam recompression technology. Now let's introduce the performance characteristics of MVR evaporator in detail.
1. The MVR evaporator vaporizes materials at a lower temperature, and the evaporation temperature is between 35 ℃ and 100 ℃, without bubbles. The feed liquid is very uniform. In addition, the material will not be used up or coking. In addition, the heating deformation of the material is also very small.
2. The price of MVR evaporator is generally high, especially the mechanical compression type MVR evaporator, which is about twice the price of multi-effect evaporator, but for new projects, it is more suitable to use MVR evaporator. And the cost can be recovered in a short time. For example, when the running time exceeds 300 days, the cost can be recovered. Compared with its purchase price, this aspect is relatively affordable. For the mechanical compression MVR evaporator, it can replace the original multi-effect evaporator, and has a strong energy-saving and environmental protection advantage. The cost can be recovered if it is used for more than 500 days.
3. The energy consumption of MVR evaporator is electrical energy. Every ton of water evaporated consumes 15 to 27 degrees of water. If it is a material with low boiling point, the electric energy used may be less than 20 degrees. Compared with the traditional multi-effect evaporator, this is a huge advantage, which can save more than 60% energy.
It can be seen from the above that MVR evaporator is an energy-saving and environment-friendly equipment. MVR evaporator will not produce pollution when used, and it is more energy-saving, which is much better than using traditional gas-consuming products; It can also run continuously without fault. In addition, choose the right product type when purchasing.
