Severe scaling in the reaction vessel used for producing nickel sulfate in the electrolytic copper purification system
Thread Content
The reaction kettle used in the nickel sulfate production process of the electrolytic copper purification system is severely scaled up; I would like to know how to remove this scale! !
Is it internal scaling or scaling in the cooling water jacket interlayer?
Severe scaling inside the reactor affects heat exchange efficiency
Scale formed inside the reactor, and it reappeared soon after cleaning
It must be some kind of gelatinous substance; it can’t be calcium-based, because the environment inside your tank isn’t acidic with copper sulfate, so calcium deposits won’t form. So first, determine what kind of thing it is.
Freeze crystallization or vacuum evaporation?
It is negative-pressure evaporation, not vacuum
Inside the reactor is the liquid resulting from two-stage electrowinning; it’s acidic. I’m not sure if it’s scale formed by additives added during electrolysis
Manual removal can only be done by knocking, and there’s a risk of damaging the enamel inside
You can give it a try, but it doesn’t seem like it will have much effect, as every cleaning process relies on professional personnel using high-pressure water guns
