Product Overview
Ceramic fibre catalytic filter tubes constitute an integrated dust removal and denitrification composite filtration material. They are manufactured by uniformly bonding nano-scale SCR catalysts to the inner surface of ceramic fibre filter tube walls, with the ceramic fibre tubes serving as the base substrate.
During operation, this product achieves highly efficient dust removal on its outer surface while simultaneously performing denitrification within the tube walls. It can concurrently remove:
Particulate Matter (PM)
Nitrogen oxides (NOx)
Dioxins
SOx (auxiliary removal)
Certain VOCs (volatile organic compounds)
It enables synergistic multi-pollutant control without compromising the filter tube's original dust removal performance, making it particularly suitable for medium-to-low temperature flue gas treatment scenarios.

Working Principle
Operates identically to standard ceramic filter tubes:
Dust-laden flue gas, under system negative pressure, causes particulates to adsorb onto the outer surface of the filter tube
Particulate matter is effectively retained, achieving high-efficiency dust removal
As flue gas passes through the filter tube walls, it comes into full contact with the internal SCR catalyst
NOx and other pollutants are reduced and decomposed under catalytic action
When dust accumulates to a certain level, reverse airflow (pulse jet cleaning) is applied within the tubes
Dust on the outer walls is dislodged and collected, allowing the filter tubes to be reused repeatedly
