COMBUSTION DEVICE IN LIQUID

摘要

PROBLEM TO BE SOLVED: To provide a combustion device in a liquid capable of preventing its corrosion caused by a concentrated liquid received from a pure liquid electrolysis process for copper electrolysis and having excellent productivity and workability.

SOLUTION: This combustion device in the liquid has a first vessel 1 which receives the liquid 10 supplied from the pure liquid electrolysis process for copper electrolysis and heats and evaporates it by a combustion flame 3A in the liquid to concentrate it and a second vessel 2 from which the liquid is discharged from a bottom part under liquid circulation with the first vessel. An outer shell 20 of the vessel is lined by fluororesin lining 23. Furthermore, the device has a fluororesin-made tube 30 which is wound around the first vessel and/or the second vessel, whose liquid inlet 30A is connected to a liquid supply outlet in the pure liquid electrolysis process, and whose liquid outlet 30B is connected to a liquid receive port 1A of the first vessel.
