Abstract
|
|
|
Foundry has an important economic value in the industry. However, the generation of air pollutants like particulate
and odor are serious. Due to the unavoidable usage of molding sand, particulate occurs in almost all the processes. That
accounts for the majority of respirable dust in the size less than 10 . As well as particulate, over 22 species of
odor-causing gases and VOCs including hydrogen sulfide and ammonia are occurred. Therefore, the development of
equipment that can simultaneously remove TVOC and particulate is regarded as an essential research. In this study, the
spraying absorbent system was connected with the shear bag filter for the purpose to remove TVOC and particulate
simultaneously. Maximization of process efficiency for the affective factors like the powder combination and injection
method is conducted. The experiment was performed at the de-molding process of one foundry plant. Through these
devices, the removal efficiency of more than 95% for TVOC was achieved with the absorbent that composed by 800
mesh Activated carbon (80%) and 300 mesh zeolite (20%). Also, the durability and economic evaluation were
assessed. In the result of Durability assessment, the available recovery to maintain the deodorizing effect at 90% was
counted to 350 degree.
