Ten Meter Long Ferrosilicon Fiberglass Blowback Pocket Filter

Fortune Cat^® Pocket Filter Characteristics：

1. Outstanding temperature resistance

Fortune Cat^® uses domestic alkali free glass fiber raw materials, which have a temperature resistance of over 260 ℃ and medium alkali glass fiber is only 220 ℃. The fiberglass filter material made from this can operate continuously between the acid dew point and 260 ℃. Bake it in a 280 ℃ oven for 2 hours without changing its physical and chemical properties or color, which other filter media do not possess.

2. High strength and resistance to bending

Its longitudinal and latitudinal strength has not been damaged by needling, and is several times more than that of ordinary felt filter materials. Due to its high strength, it can be processed into filter bags that are 10 meters or even 12 meters long for use; The filter bag will not shrink under high temperature, almost maintaining its original size, and will not affect the gap between the filter bag and the skeleton, ensuring the cleaning effect. The elongation rate of fiberglass filter bags is less than 8%. During filtration operation, the weight of the filter material plus the weight of the dust layer will not cause the filter bags to elongate, and it also greatly reduces the periodic damage caused by air pressure cleaning to the filter bags.

It adopts a single wire diameter of 3.8-5.0 μ Using ultra-fine glass fiber as raw material, the finer the diameter of a single fiber of glass fiber, the better its bending resistance, and the longer the service life of the filter material produced.

We have concluded through experiments that 5.0 μ M’s fiberglass is better than 9 μ The bending resistance of m’s fiberglass is 2.5 times higher (as shown in the figure below); And 3.8 μ The bending resistance of m’s fiberglass is 9 μ More than 5 times the size of fiberglass. That is to say, from the perspective of bending resistance, the diameter of a single filament is 3.8 μ With a single wire diameter of 9 μ The service life of filter bags made of m fiberglass will differ by 15-20 times.

3. Resistance to oxidation and corrosion

At room temperature, it is resistant to the erosion of organic and inorganic acids, and maintains good performance stability in weak alkalis. After experimental testing and analysis, its acid resistance performance is several times higher than that of ordinary fiberglass filter materials;

It will not be oxidized by oxygen or nitrides, so there is no need to consider the issue of high or low oxygen content in the dust collector. Therefore, the glass fiber has outstanding oxidation resistance and corrosion resistance, and the filter material has been impregnated with PTFE lotion as a whole. PTFE lotion impregnation will form a dense protective film on the surface of the glass fiber, so it will suffer little erosion during the operation of the dust removal equipment.

4. Excellent waterproof performance

It adopts a unique process in post-processing, and the finished product exhibits excellent waterproof performance at room temperature and high temperature, which is more conducive to its application in cement working conditions. The waterproof performance of the filter material is very good, with a waterproof level of up to 3.5 at room temperature and up to 4 at high temperatures.

The thickness of the filter material is about 0.9mm, which is only one-third of that of felt filter materials, and the texture is soft. When cleaning, the filter material shakes in a serpentine shape, making the dust easy to peel off; Low cleaning pressure, fewer cleaning cycles, and longer cleaning cycles can effectively reduce compressed air consumption, reduce maintenance, and save operating costs. Its substrate is a two-dimensional FN215 filter cloth, and due to its structural characteristics, the system operates with smoother resistance compared to three-dimensional filter materials.

5. Easy to clean dust and low resistance

Due to the special self-cleaning and hydrophobic properties of PTFE (polytetrafluoroethylene), the filter material is easy to clean, and the dust does not penetrate into the interior of the filter material. Therefore, it can ensure the airflow flux without increasing operating resistance, making it an ideal high-temperature flue gas filtration material.

The micropores on its surface are small and uniform (0.10-2.0 μ m) It can separate all the dust larger than the micropore diameter, which is different from the deep filtering mechanism of ordinary filtering materials filtering through the powder layer. The filtering material is mainly surface filtering through micropore membrane. The surface of the filter material can almost intercept all the dust in the dusty airflow, so the filter material has a very high filtration efficiency.

6. High filtering accuracy

It shakes the filter material in a serpentine shape during ash cleaning, making the dust easy to peel off; Low cleaning pressure and fewer cleaning times effectively reduce the consumption of compressed air and save operating costs. As long as it has an ideal airflow distribution and a reasonably designed ash cleaning system, its pressure difference during operation is very stable, and the system resistance increases very slowly after long-term operation.

Fortune Cat^® filter bag can:

Improve the capture rate of fine dust and reduce dust emissions;

Improve the dust cleaning ability of filter bags, with low resistance and low pressure difference;

Durable and long-lasting, extending the service life of filter bags;

Reduce fan energy consumption;

Increase ventilation volume;

Having the ability to overcome accidents and be able to regenerate;

Reduce the accumulation of dust in the filter material, causing blockage of the filter material.

The key element for achieving high filtering accuracy is weft yarn puffing：

The weft yarn is processed by special bulking process, which makes the fiber structure more fluffy, the fabric structure thicker, the fiber gap more compact, increases the surface area, prolongs the dust collection time, and is beneficial for fine dust agglomeration. The powder layer has a fluffy structure, large void ratio, more uniform holes, better dust removal effect, and less resistance. Compared with ordinary fiberglass filter materials, the weft yarn adopts puffing technology and has the following characteristics:

At the same weight, the thickness of the expanded yarn filter cloth is thicker;

The breathability of bulked yarn filter cloth is better than that of ordinary filter cloth, with good uniformity;

Good filtration performance, loose yarn, large surface area, conducive to interception, diffusion, static electricity, gravity, inertia and other effects, capturing dust;

After post-treatment, the sizing agent is easy to wrap and form a protective film on the surface of a single fiber in the buled yarn filter cloth;

Bulked yarn filter cloth is beneficial for the composite of substrate and film, improving the fastness.

The key element for achieving high filtration accuracy is PTFE microporous film:

The ePTFE membrane produced using polytetrafluoroethylene resin imported from DuPont or Japan has a smooth surface, chemical resistance, uniform and small pore size, high porosity, and uniform air permeability. At the same air permeability, the membrane has a large thickness value, good wear resistance, long service life, high filtration efficiency, and good fastness. It can withstand a blowing pressure of 8kg without detachment. After practical application, the detachment rate of the microporous membrane is less than 5%.

According to electron microscopy, the surface of the microporous film has a spider web like microporous structure, and the pore size of the microporous film ranges from 0.1 to 2 μ Between m, with a thickness of 15 μ Approximately m, with a porosity of over 85%, reaching 1 × 109/cm2. The later FN215 woven filter material has high filtration accuracy, further ensuring the achievement of ultra-low emission standards for flue gas.

The key element to achieve ultra-low emissions is the sewing of filter bags：

The sewing of filter bags complies with industry standards such as HJ/T326-2006 and GB/T 12625. Adopting CNC slitting machine for cutting, with stable and no deviation in size; Continuous production lines are used for sewing control, resulting in better and more stable product quality; The upper and lower pieces of the seam on the bag body are flat, and the interface between the bag mouth and bottom is folded evenly. The bag body is sewn with high-strength PTFE thread or fiberglass thread to prevent opening caused by corrosion; Strictly follow the standards of ISO9001:2008 quality management system to guide each production and management process.
