Introduction
The integrated device of ceramic fiber filter tube for dust removal and denitration is a new type of ceramic membrane material that combines efficient dust removal and denitration functions. By loading high-efficiency denitration catalyst on the internal pore structure of high-temperature ceramic membrane material, the dust in the flue gas is efficiently removed at high temperature (200-420℃). Then, the catalyst loaded in the multi-dimensional pore structure inside the ceramic membrane support and NH3 added are used to decompose NOX in the flue gas, achieving efficient dust removal and denitration at the same time. The denitration efficiency can reach more than 80%, and the smoke and dust emission is ≤10mg/m³, achieving ultra-low emission.
Working principle
Cooperate with dry process technology for desulfurization and acid removal, and flue gas conditioning.
The flue gas dust is blocked on the surface of the filter tube, and the filter cake layer on the surface of the filter tube can perform secondary desulfurization.
The clean flue gas passes through the filter tube wall, and NOx reacts with NH3 under the action of catalyst, and is converted into N₂.
The purified gas enters the clean air chamber and is discharged by a fan.
When the dust deposits on the surface of the filter tube to a certain value, compressed air is used to pulse clean the filter tube.
