Technical field
The utility model relates to a kind of continuous crystallizing systems of ferrous sulfate.
Background technique
During industrial production titanium dioxide, need to remove by-product ferrous sulfate, and the solubility of ferrous sulfate by
Temperature is affected, therefore mostly uses vacuum evaporation mode and freezing and crystallizing mode that ferrous sulfate is precipitated in industrial production.Vacuum
Evaporation mode is to extract steam with water circulation vavuum pump out, makes to form vacuum environment in vacuum crystallization tank, while ferrous sulfate is molten
Moisture constantly absorbs heat evaporation in liquid, and causing ferrous sulfate solution is supersaturated solution to which errous sulfate crystal be precipitated；Using true
Empty evaporation mode is generally required to be vacuumized by recycling twice, can consume great lot of water resources in the process, and steam using vacuum
Operation controls more complex and is difficult to be found when vacuum tank leaks when originating party formula；Being using freezing and crystallizing mode will be cold
But it is passed through refrigerant in disk, the solution in container is cooled down indirectly, is analysed after so that ferrous sulfate solution is reduced to assigned temperature
Errous sulfate crystal out, because freezing and crystallizing mode keeps the cooling efficiency of sulfate liquid solution lower using cooling solution indirectly, and
The time that freezing and crystallizing mode is smaller to the treating capacity of sulfuric acid solution, precipitates crystal is long, while the crystal being precipitated outside can be adsorbed on
On the outside of cooler pan, hot transmitting is influenced, cannot continuously be precipitated crystal for a long time.
