There are several very small holes on the outer wall of one of the company’s absorption towers, and water occasionally leaks out from these holes (it is initially suspected that rainwater gets into these holes and then flows out; since the pH level is close to 7 and the medium inside the tower is a strong acid, it is unlikely that the leaking fluid comes from inside the tower). This results in corrosion marks on the wall of the tower. The interior of this tower is lined with fluoropolymer material. I would like to ask what purpose these holes serve
Some lining equipment is equipped with exhaust vents due to structural reasons. It’s best to find the drawings and take a look; as long as the lining isn’t damaged, that’s fine.
Oh, it seems that the exhaust vent is the more likely option, since it’s been over 10 years and the drawings can no longer be found
It should be a signal hole, used for detecting leaks; if liquid flows out, it means the lining is damaged
