TREATMENT DEVICE OF ACIDIC DEW CONDENSATE

摘要

PURPOSE:To make neutralization reaction sure and to prevent water leakage by providing plural staircase-like treatment tanks formed of a partition plate between both walls of a box body, disposing a cylindrical basic material in the bottom of each treatment tank and forming the box body and the partition plate into one body. CONSTITUTION:The acidic dew condensate of 4.0pH and 30 deg.C formed on the surface of a latent heat type exchanger is conducted at 120ml/h rate through an inflow port 4 into a body of the treatment device 1. The product of corrosion and dirt and removed in a settling tank 7, and the water drops through the guide groove 12 of a tongue part 11a into the cylinder of a neutralizer 10a. As a result, the acidic dew condensate flows from the bottom of the neutralizer 10a to the outside of the cylinder and is dropped through the guide groove 12 of the tongue part 11b provided on the partition plate 6b of a treatment tank 8a into the neutralizer 10b in the next stage until finally the water is discharged through an outflow port 5 to the outside of the body 1. The initial pH of the discharged acidic dew condensate is 7.3 and the pH after 3,000hr is 6.9. The neutral state is thus maintained.
