The smoke includes fuel ash, coal particles, oil droplets, and products of high-temperature cracking. Flue gas needs to be denitrified before discharge. The current mainstream denitrification processes are SCR and SNCR.

[0003] In order to prevent the influence of dust on denitrification, a dust removal structure is usually set at the smoke inlet of the denitrification device for dust removal. In the relevant dust removal structure technology, the filter for filtering smoke is arranged inside the dust removal box. In order to ensure the sealing effect of the dust removal box, the door of the dust removal box is usually fixed and sealed by the cooperation of bolts and seals.
