Application:
It is suitable for evaporation, concentration andcrystallization of industries such as chemical, food, pharmaceutical, printingand dyeing, environmental protection engineering, sewage waste liquidevaporation and recovery.It is especially fit for materials of highcrystallization, high concentration and high viscosity. Such asevaporation,crystallization,and recovery of materials such as sodium chloride,sodium sulfate, ammonium chloride and ammonium sulfate, calcium chloride andlithium hydroxide.
And the concentration of high viscosity, high concentrationand easy fouling materials, such as tomato sauce, jam, pulp type juice and highconcentration sugar solution processing and concentration production. It iswidely used in China.
System structure:
Heater, separator (vapor-liquid separation, crystallizer),condenser, condensate water storage tank, preheater, forced circulation pump,liquid transfer pump, vacuum pump, condensate water pump, crystallization(thick) kettle, centrifuge, work platform, electrical control cabinet,automatic control system and valves pipelines etc.
Features:
1. It has the advantages of high heat transfer coefficient,big evaporation capacity, prevention of wall fouling and pipe blocking, etc. Itis especially suitable for materials which are easy to fouling in theevaporation process and materials which have crystal precipitation duringevaporation.
2. The separator is equipped with a special defoaming deviceto avoid running materials, punching materials and liquid entrainment.
3. Compact structure, small floor space, smooth layout,convenient operation and stable performance.
4. The structure such as DTB or OSLO separation forms anoptimal fit with the forced circulation pump, so that the crystal and the clearliquid are quickly and effectively separated, and the crystal particles arecompletely prevented from entering the heat exchange tube.
5. It is equipped with automation system, automatic feedingcontrol, automatic heating temperature control, automatic setted concentrationdischarge control.It can also be equipped with protection measures forcrystalline materials in case of sudden power failure and fault. And otherautomatic operation control such as safety and alarm.
