Why is there so much acidic sludge in the outlet pipeline of the main fan?
Thread Content
I think it is due to poor purification and dust removal performance, as well as severe acid foam in the drying tower
Please introduce the purification configuration and the dust emission standards at the purification outlet.
Please explain in detail, do not answer questions to yourself, and avoid providing content that is imaginary and has no practical meaning.
The link below is for the same issue. It seems that both the electrostatic precipitator and the mist eliminator are not very efficient. http://bbs.hcbbs.com/thread-121347-1-1.html
Excessive moisture remains after drying, the conversion temperature is not well controlled, and sulfur trioxide condenses.
The moisture content after drying is too high; this seems to have nothing to do with poor control of the conversion temperature or the condensation of sulfur trioxide. Check the purification parameters
Thank you, brother on the sixth floor, for the excellent correction. What I mean is that there is a lot of acidic sludge at the fan outlet; the reason for this is that when the moisture level is too high, the drying tower produces excessive acidic foam, and when the purification standards are not met, this acidic foam combines with impurities such as mineral dust and carbon to form acidic sludge. As for the statement in the original post that \"poor control of the conversion temperature leads to the condensation of sulfur trioxide,\" I was indeed wrong; the acidic substance that condenses here should be present in the heat exchanger and the first and second smoke exhaust pipes. Brother on the sixth floor, am I expressing this correctly?
