[0003] Because some pollutants in flue gas are easy to poison the catalyst and make it invalid, the dust particles cover the surface of the catalyst and reduce its activity, and SO2 in flue gas reacts with some unreacted HN3 in flue gas to generate products, which causes corrosion of the catalyst and blockage of the honeycomb hole, thereby reducing the reaction area of the catalyst and the removal rate of nitrogen oxides, and increasing the system resistance. For the treatment of catalyst blockage, there are two common ways to clean the blockage of the existing honeycomb catalyst, one is to use a steel bar to dry the channel, and the other is to use ultrasonic waves. Although the two treatment methods can treat the blockage to a certain extent, they have no obvious effect on the seriously blocked channels. UTILITY MODEL CONTENT
