Working principle and features:
MVR forced circulation evaporation system consists of evaporator, separator, forced circulation pump and steam compressor. The material in the evaporator tube and the steam outside the tube heat exchange, temperature rise; After the temperature rises, the solution is divided into steam and solution two phases. The steam rises to the separator, and the defoamer separates the droplets entrained in the steam, and then transmits them to the compressor after purification. The compressor transmits the compressed steam to the shell side of the evaporator for heating steam, so as to realize the secondary steam recycling and continuous evaporation. Evaporation produces secondary steam overflow from the material, the material is concentrated into supersaturated material, crystallization, crystal slurry from the circulation pipeline with the discharge pump output; Mother liquor into the forced circulation pump, under the action of the circulation pump into the evaporator and then evaporate, so the cycle continues to evaporate concentration, crystallization. Its advantages are: 1. Suitable for large viscosity materials, 2. 3. High concentration ratio; 4. High pipeline flow rate, not easy to dry wall or scale.
