Ceramic Fiber Filter Tube Denitrification and Dust Removal Integrated Equipment Product Introduction

Ceramic fiber filter tube denitrification and dust removal integrated equipment is an efficient and environmentally friendly flue gas treatment technology, particularly suitable for your focus on desulfurization, denitrification, and dust removal fields. It achieves the synergistic removal of multiple pollutants through catalysts on the ceramic fiber filter tubes, featuring high temperature resistance, corrosion resistance, and long lifespan, ensuring stable ultra-low emission standards.

      I. Technical Principle

• ‌Dust removalCeramic fiber filter tubes have a high porosity (over 80%), high filtration accuracy, and dust emission concentration can be as low as 1mg/Nm³.

• ‌De-NOxThe vanadium-titanium or rare earth precious metal oxide catalysts loaded on the filter tube reduce NOx to N₂ and H₂O through SCR reactions, achieving a denitrification efficiency over 90%.

  ‌DesulfurizationThe equipment achieves auxiliary desulfurization through the formation of a layer cake of lime particles on the surface of the filter tubes, boosting desulfurization efficiency by 5% to 15%.

Section Two: Core Advantages

• ‌Efficient coordinationIntegrated design for dust removal, denitrification, and desulfurization to be conducted simultaneously, with a short process and minimal land requirement.

• ‌High-temperature and corrosion-resistantWithstanding temperatures up to 250~400°C, short-term up to 450°C, and strong resistance to acids, alkalis, and oxidation.

• ‌Long lifespan, low maintenanceFilter tube lifespan: 3-5 years, catalyst effective lifespan: 3 years, low differential pressure, significantly reduced operating energy consumption.

Section 3: Application Cases

• ‌Glass IndustryLongjing Environmental Protection has upgraded a 900t/d float glass production line for Taiwan Glass Group. Post-implementation of this technology, SO₂, NOx, and dust emissions have consistently remained ultra-low, and zero wastewater discharge has been achieved.

• ‌Coking industryHunan Lianggang Coking Project utilizes an integrated ceramic catalytic filter tube technology, featuring high desulfurization efficiency, compatibility with dry/semi-dry processes, and reduced catalyst poisoning.

Section 4: Applicable Fields
