Under every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig.1, Fig. 1 is the structural schematic diagram that the utility model copper sulphate mother liquor purification recrystallizes system, the present embodiment
A kind of copper sulphate mother liquor purification proposed recrystallizes system, including purification system, vapo(u)rization system and crystal system, the purification system
System includes purification reaction kettle 1 and filter press 2, the discharge port of the purification reaction kettle 1 by a pump 10 and the filter press 2 into
Material mouth connection.The vapo(u)rization system includes separator 3, heat exchanger 4, surge tank 5 and vacuum pump assembly 6, and the of the separator 3
One feed inlet is connect by a pump 10 with the discharge port of the filter press 2, the first discharge port of the separator 3 and the heat exchange
The feed inlet of device 4 connects, and the discharge port of the heat exchanger 4 is connect with the second charging aperture of the separator 3, the separator 3
The second discharge port connect with the feed inlet of the surge tank 5, the pumping of 10 groups of the discharge port of the surge tank 5 and the vacuum pump
Port connection.The third discharge port of the separator 3 is connect by a pump 10 with the feed inlet of the crystal system, the crystallization
System is set as a crystallization kettle 7, and the separator 3 is set as an evaporation and concentration separator.
In the present embodiment, when carrying out purification recrystallization operation to copper sulphate mother liquor, copper sulphate mother liquor is put into institute first
It states in purification reaction kettle 1, adds drug and carry out purification reaction.It should be noted that containing metal in the copper sulphate mother liquor
Impurity and organic matter, therefore, the drug of investment include hydrogen peroxide and sodium hydroxide, and hydrogen peroxide can be with having in copper sulphate mother liquor
Machine object is reacted, and organic matter is decomposed into carbon dioxide, sodium hydroxide can be carried out with the metal impurities in copper sulphate mother liquor
Reaction generates precipitating and separates with copper sulphate mother liquor.After purification reaction, purified copper sulphate mother liquor is sent to filter press 2
Inside be separated by solid-liquid separation, by copper sulphate mother liquor impurity and precipitating further separate with copper sulphate mother liquor, then mistake be filtered out
Copper sulphate mother liquor after miscellaneous introduces in separator 3.It should be noted that the sediment stayed in the filter press 2 can take out
Landfill and burning disposal are done in drying, prevent from polluting the environment.After copper sulphate mother liquor enters separator 3, first gone out by it
Material mouth enters the heat exchanger 4, and heat exchanger 4 heats copper sulphate mother liquor by high-temperature steam, by the temperature of copper sulphate mother liquor
Degree increases rapidly.Copper sulphate mother liquor after heating is introduced again into separator 3.It should be noted that separator 3 passes through buffering
