MVR-DTB Continuous Crystallization Evaporator

MVR-DTB Continuous Crystallization Evaporator:
A MVR-DTB Continuous Crystallization Evaporator comprises MVR system and DTB crystallization system. DTB crystallizer is highly efficient and years of observation of the operating performance demonstrates that this crystallizer is good at performance, able to form larger size crystals (size 600-1200um), highly productive, and not easy to encrust, and therefore has become a main form of continuous crystallizers. It can be used for vacuum cooling, evaporation, and reaction-method crystallization.
In the middle part f the DTB crystalizer there is a draft tube guarded by a circular baffle at its perimeter. Driven by the screw propeller, the fluid rises inside the tube to the edge, then turns back to the bottom along the annular channel formed by the draft tube and the baffle, and is re-sucked into the draft tube on the bottom. The cycle repeats endlessly, creating a good condition for crystallization.
This kind of crystallizer is capable of clearing mother liquor overflow and eliminating fine grains. When coupled with the MVR, the crystallizer will not only get crystals of better granularity but also be more power efficient.

Technical Characteristics:
1. Low energy consumption, low operating costs.
2. Small space occupation.
3. Require fewer public utilities and less total investment.
4. Stable operation and high degree of automation.
5. Require no primary steam.
6. Short retention time due to frequently used single effect.
7. Simple process, high practicability and excellent service performance at some loads.
8. Low operation costs.
9. Capable of evaporating at and below 40 degree without refrigerating plant and particularly suitable for heat sensitive materials.
