Catalyst Fabric Filter
Regulations on hazardous substances contained in exhaust gas from incinerators for municipal waste, etc. have been strengthened in recent years. In particular, emission regulations for dioxins have been tightened, and dioxins must be reduced to 0.1 ng-TEQ/m³N or lower for newly established incinerators.
The catalyst fabric filter incorporates a filter cloth equipped with a catalyst which decomposes and removes gaseous dioxins, and has removal performance that sufficiently clears the emission regulations.
Compared to the conventional methods (catalyst tower, activated carbon adsorption tower, and activated carbon blowing), the catalyst fabric filter does not require the installation of processing towers, silos, or blowing devices, and therefore occupies a smaller installation space.
