In the gas treatment system, the working principle of which is to wash the waste gases under raschig rings, the principle of absorption of gases by liquids is applied.
The gas aimed to be purified is taken from the environment with the suction fan and forced to go up through the raschig rings.
Thanks to the gravity force and the sprinkler system, the water that goes down and the gas that encounters in these rings breaks up and encounters as much surface as possible in the liquid phase. Thus, the gases coming out of the "scrubber" chimney are free of harmful contents. However, the remaining liquid has turned into acid and is highly corrosive.
In this case, the pH value of the liquid phase, which is acidic, is increased to be basic or neutral with the dosing system during the cycle. Thus, it is aimed to increase the durability of the system and to decrease the saturation of the liquid phase in the gas absorption process.
