Product Description

Product Description

With the increasingly stringent environmental protection policies and the continuous improvement of industrial waste gas emission standards, traditional flue gas purification technology has been unable to meet the needs of coordinated control of multiple pollutants. As a new type of flue gas purification material, ceramic fiber filter tubes have gradually become a popular choice in flue gas purification integrated technology with their multifunctional integrated characteristics such as efficient dust removal, denitrification, and dioxin removal.

Product Name	Ceramic fiber filter tube
Core Components	Ceramic Candle Filter
Use	Industrial dust removal filter tube

Principle

Ceramic fiber filter tubes are wound with high porosity and low density ceramic fibers (diameter 2~3 μm), and their basic materials are composed of aluminum silicate fibers and inorganic adhesives. The filter tube is loaded with a denitrification catalyst (such as V2O5-WO3/TiO2, etc.), and the catalyst is evenly distributed between the ceramic fibers through processes such as impregnation, sol-gel coating or vacuum centrifugal coating. Ceramic fiber filter tubes not only have efficient dust removal function, but also can remove NOx and dioxins through the action of catalysts at high temperatures (200~450℃).

 

The dust removal mechanism of ceramic fiber filter tubes includes inertial collision, direct interception, diffusion and gravity sedimentation, which can efficiently remove dust from flue gas. At the same time, the nanocatalyst loaded in the multidimensional pores inside the filter tube reacts with the injected NH3, which can efficiently catalytically reduce NO. Since the flue gas flow rate of the filter tube is low (0.8~1.2 m/min), the flue gas stays in the filter tube for a long time, and the catalyst utilization rate can reach 100%.

Application Areas

Ceramic fiber filter tubes have the following significant characteristics, which make them have broad application prospects in flue gas purification integrated technology:

 

1. High porosity: The porosity of ceramic fiber filter tubes is as high as 85%, which is not easily affected by thermal expansion and contraction and has good mechanical strength and stability.

 

2. Multifunctional integration: Ceramic fiber filter tubes integrate denitrification, deacidification, dust removal and dioxin removal, and can treat multiple pollutants at the same time, reducing the equipment footprint and operating costs.

 

3. High temperature resistance and corrosion resistance: Ceramic fiber filter tubes can operate stably in high temperature (200~450℃) and corrosive environments, and are suitable for high temperature flue gas treatment scenarios such as waste incineration and biomass power generation.

 

4. Long service life: Compared with traditional bag filter, ceramic fiber filter tubes have a longer service life, usually up to 5 years or more, reducing replacement frequency and maintenance costs.

The integrated purification technology of ceramic fiber filter tubes has been applied in many industries, especially in the fields of waste incineration and biomass power generation. Taking the pilot demonstration project of a waste incineration power plant in Jiangsu as an example, the project adopts the "dry deacidification + catalyst ceramic fiber filter tube integrated system + heat exchange + activated carbon + bag filter" process, and the flue gas treatment effect is remarkable. After third-party testing, the removal efficiencies of NOx, SO2, HCl, particulate matter and dioxins reached 97.6%, 84.1%, 74.8%, >99.9% and 99.9% respectively, which fully complies with the requirements of the "Standards for Air Pollution Control of Domestic Waste Incineration" (DB13/5325-2021).

 

With the increasingly stringent environmental protection policies and the continuous advancement of flue gas purification technology, ceramic fiber filter tubes, as a high-efficiency, multifunctional integrated flue gas purification material, have broad market prospects and application potential. Its efficient dust removal, denitrification, and dioxin removal capabilities, as well as its high temperature resistance, corrosion resistance, and long service life, make it perform well in flue gas purification in the fields of waste incineration, biomass power generation, and hazardous waste treatment. In the future, with the further optimization of technology and the reduction of costs, ceramic fiber filter tubes are expected to be widely used in more industries, helping to achieve my country's air pollution control goals.
