Abstract
PURPOSE: To suppress a rise of running cost due to chemical fluids and to prevent occurrence of the secondary environmental pollution to drainage systems by making multistage treating in the order of a cooling tower, an absorption tower of chemical fluids and an adsorption tower of activated carbon in the titled device using the liquid-liquid absorption method.
CONSTITUTION: Offensive odor gas 1 is sucked by a fan 13 and brought into contact countercurrently with NaOH solution spouted from a nozzle 26 in a packed layer 22 in a cooling tower 10 where it is cooled and absorbs HCl and HF. The NaOH solution is supplied into the tower from a storage tank 15 by a pump 34 while maintaining its concentration with a pH meter. The gas that passed through a mist separator 24 and a duct 41 is supplied from a storage tank 4 by a pump 33 in the packed layer 21 of an absorption tower 11 of chemical fluids and brought into contact countercurrently with chlorine dioxide solution spouted from a nozzle 25 to absorb and oxidize the odorous component. The gas that passed through a mist separator 23 and a duct 42 is further introduced into an adsorption tower 12 of activated carbon where unabsorbed odorous component is adsorbed and removed. The perfectly deodorized gas is discharged to the open air.
