AI Technical Summary
During operation, denitrification SCR catalysts are easily clogged by impurities such as dust and fly ash, leading to increased flow resistance, reduced denitrification efficiency, and frequent catalyst replacements increase equipment maintenance costs.
A purging device was designed, which uses compressed air generated by an air pump to enter the catalyst voids through a branch pipe to clean up the accumulated dust, and collects the dust through a dust collection box. The magnetic connection facilitates cleaning and ensures stable operation of the device.
It effectively prevents catalyst clogging, improves flow efficiency, reduces equipment maintenance costs, and ensures denitrification efficiency and environmental cleanliness.
