Introduction
The Dust and NOx Integrated Filter Tube is designed with dual functions and high efficiency in removing dust and NOx.
The filter tube is equipped with a NOx catalyst, allowing it to have integrated dust and NOx removal functions.
The NOx removal process works at a temperature of 250-400°C, with ammonium sulfate ≥280°C.
The filter tube has high NOx removal efficiency, achieving ultra-low emissions in one go.
The filter tube has a long service life and a surface filtering design, reducing the risk of alkali metal poisoning.
Working principle
It is used in combination with dry-process technology to remove sulfur, acid, and regulate smoke quality.
Smoke particles are trapped on the surface of the filter tube, and the filter cake layer on the surface of the filter tube can perform secondary NOx removal.
Clean smoke passes through the filter tube wall and undergoes chemical reactions with NOx and NH3 under the catalytic action of the catalyst, converting them into N2.
The purified gas enters the clean air chamber and is discharged by the fan.
When the dust deposited on the surface of the filter tube reaches a certain value, compressed air is used to pulse-clean the filter tube.
