What is a Pleated filter bag?

Pleated filter bag is also known as the “star filter bag”. It is a new type of filter bag that can be applied to pulse bag housings. The filter cage used with pleated filter bags requires special design, while other support components are of the common design. Pleated filter bags can be made with different filter materials such as Polyester, Aramid cloth, PPS cloth, FMS material, P84 cloth, acrylic material. It receives different surface treatments according to the characteristics of flue gas and dust and emission requirements.

The common type of filter bag is generally cylindrical. The cylindrical filter bag has stable structure and good dust particles removal effect, but the filtering surface area is limited. Compared with the traditional cylindrical bag, the folded filter bag has an increased filtration surface area under the same size and dimensions thereby significantly reducing the system’s differential pressure, ash removal frequency and energy consumption. Achieving the goal of energy conservation and emission reduction.

It is based on the basic principle of bag dust removal. The filter surface area of the system can be greatly increased without the carry out structural downtime transformation. It can directly replace the traditional products.

Pleated filter bag meets the emission standards required by environmental protection.

The pleated filter bag has a service life of three times of a traditional filter bag .It does not require any change of structure of the dust remover box / filter housing . It solves the problems of large differential pressure, high filtering wind speed and difficult dust particles removal of the original filtration system. It also reduces the working condition requirements for designing the floor area of the new dust remover / filter housing .It can also increase the occasions for the dust remover to handle flue gas.

How to check what kinds of filter bag is suitable for the bag house?

When old filter bag requires replacement:

Once you remove the filter bag from the filter housing, you can just take some measurements and pictures to send them to us. We would be able know your filter bag specifications using this method.

If you are able send us the samples, we can analyse the sample bag material and treatment.

We can make a sample for you to test its fitment with your bag house within a few days.

What are the special production processes for Pleated filter bags?

The Pleated filter bag is made of needle punched felt. The most traditional needle punched cloth on the market only requires acupuncture, singeing, heat setting, and rolling before use. However, in complex working conditions with special and high filtration requirements. Special production procedures are used to improve the performance of filter bags.

Filter bags can be treated with singeing, calendaring, water and oil repellent coating, PTFE impregnation and lamination as per customer’s demand and specifications.

When you want to install a new filtration system and need some advice:

1. We will send you a configuration to fill it according to your specifications and conditions like temperature, chemical content and others. After you send it back to us .We will inform you about what kind filter bag is suitable for you.

2. Our engineers can arrange online meeting with your engineer or provide you with the configuration based on your demand.

What are the advantages of Pleated filter bags?

Advantages of Pleated filter bags:

1. It can directly replace the existing filter bag of the bag type dust remover/filter housing, without the need to modify the main structure of the dust collector equipment, and the filtering area can be increased by 50-150% after replacement.

2. It can significantly reduce the system pressure difference, thereby improving the overall performance of the system and the service life of the filter bag itself.

3. The frequency of ash removal can be greatly reduced and the interval of ash removal can be extended.

4. Compared with the traditional filter bag, the pulse efficiency is significantly improved due to the special structure of the folded filter bag.

5. The effective use area of the dust removal filter bag is increased, reducing the air flow speed between the dust removal filter bags. Which greatly optimizes the online ash removal effect;

6. The special design of the filter bag and dust removal framework of the folded filter bag greatly reduces the fatigue damage and intermittent emission caused by pulse blowing.

7. The framework has no transverse support ring, and the effective contact area is large, completely avoiding direct impact on the filter bag.

8. As required, the length of the pleated filter bag can be shortened while increasing the filtering area and the system operation can be optimized.

9. Greatly reduces the consumption of compressed air, the load of air compressor and pulse valve.

10. The fan load is greatly reduced. Thereby reducing system energy consumption significantly.

11. The system maintenance cost is significantly reduced, including energy consumption, auxiliary equipment, parts and labor.

12. Any existing filter bag material suitable for the system requirements can be used.

13. The traditional filter bag can still be used as the emergency spare part of the pleated filter bag. But the corresponding framework shall be used.

What are the physical and mechanical properties of Pleated filter bags?

As the folding filter bag only changes the shape of the filter bag, it does not change the material. The performance parameters of the folding filter bag correspond one-to-one with the needle felt used.
