High-temperature flue gas at the outlet of the boiler enters a reactor to be mixed with a denitration reducing agent, the mixed high-temperature flue gas enters a denitration dust removal equipment purification shell, and a plurality of ceramic fiber filter tubes are installed in the shell. The dust in the flue gas is intercepted on the outer surface of the ceramic fiber filter tube to form a filter cake, so that the dust filtering effect is ensured. The denitration catalyst is implanted in the wall of the ceramic fiber filter tube, so that the selective catalytic reduction reaction of NOx can be realized, and the problem of catalyst poisoning caused by alkali metal is solved because dust is intercepted on the outer wall of the ceramic filter tube.

Therefore, after the resistance of the denitration dust removal equipment reaches a certain value, the dust of the ceramic fiber filter tube needs to be removed in time through the compressed air blowing dust removal system. The dust is separated from the outer surface of the ceramic fiber filter tube and falls into the dust storage hopper, and the dust is collected through the dust conveying device.
In the purification shell of the existing denitration dust removal equipment, the gas after purification and the boiler flue gas are separated by the flower plate and the ceramic fiber filter tube. When the ceramic fiber filter tube is installed, the ceramic fiber filter tube is inserted into holes uniformly arranged on the pattern plate from top to bottom. And then the ceramic fiber filter tube flange is turned and pressed tightly through a pressing plate so as to be fixed. The ceramic fiber filter tube is a core device in the denitration dust removal equipment, and the boiler flue gas is subjected to dust removal, denitration and purification treatment to reach the emission standard. The flue gas treatment capacity of the ceramic fiber filter tube is determined by the length and the diameter of the ceramic fiber filter tube, and the longer the length is, the higher the flue gas treatment capacity is.
