I would like to ask how to increase the secondary current of a sulfuric acid electrodesuperheater
Thread Content
For an electrostatic demister used in the production of acid from 60,000 tons of pyrite, after it is shut down and cleaned, the secondary voltage is 65 KV; only then can the secondary current reach 40 MA. The electrostatic demister in question is a 144-tube conductive fiberglass type. According to the specifications in the books, the current should be 0.2 MA/m, which means the current should be 144*4*0.2 = 115.2 MA in order to meet the production requirements. I’m not sure if my calculation is correct. If it is correct, then how can the current be increased? Could it be that the settings or design of the constant current supply control cabinet are inadequate? How can this be fixed? Thank you!
It may be due to changes in the composition of the smoke, which leads to a lower conductivity and thus a reduced current.
The secondary current should be set at 80~100mA
I sent over a few keys; I suspect that there’s sulfur sublimation in your electrostatic demister, so make sure to keep an eye on the parameters near the furnace. The electric demisting design should be fine; after shutting down the system for cleaning, give it a try under no-load conditions to see what performance can be achieved
