The issue of excessive fluoride content in smelting flue gas
Thread Content
The excessive fluoride content in the smelting flue gas from our plant has caused two serious accidents involving the collapse of the ceramic ring fillers in the drying towers. We are at a loss for solutions; we use water glass to remove fluoride, but I wonder if there is a better method that can completely resolve this problem
That amazing? Is it a rounded arch or a straight arch? It is possible to consider replacing part of the plastic packing in the purified gas cooling tower with ceramic packing to absorb fluorine from the flue gas. This post was last edited by in the blink of an eye on 2007-12-28 08:20]
The filler has been corroded, so wouldn’t the cooling effect deteriorate? Besides, the corroded packing is also difficult to handle once it reaches the dilute acid circulation tank! What do spherical arches and ribbed arches refer to? This post was last edited by lanneretcp on 2007-12-28 10:21]
Ceramic fillers are evenly mixed into the plastic fillers without affecting mass and heat transfer. Spherical arches and strip arches refer to the filler support devices of towers.
What equipment is installed in your factory’s flue gas purification section?
I think the fluoride content should be reduced before entering the drying tower, so purification equipment is very important.
What is the acid temperature at the upper tower of the purified gas cooling tower? Control fluoride levels by minimizing the acid temperature and concentration in the upper tower of the final washing unit in the purification process.
