Filter Bags Manufacturers


Filter bag is an efficient dust removal filter material, which has good ventilation performance, high dust removal efficiency, and has certain acid resistance, alkali resistance and heat resistance. Multi-sided brushing is used in the weaving process, which increases the thickness of the fabric and is flexible , The dust removal effect is very good, the dust removal rate can reach 99.999%. The dust removal filter bag is made of polyester staple fiber or long fiber. The service life is generally 4-6 times that of glass fiber fabric. It has good air permeability, high dust collection rate, dust removal capacity, and dust removal efficiency can reach 98.99%.

The filter bag is the heart during the operation of the bag filter. Usually, a cylindrical pulse filter bag is suspended vertically in the dust collector. The dust-containing gas enters the dust collector from the air inlet, passes through the deflector of the ash bucket, Some large particles of dust are separated by inertia and fall directly into the ash hopper. Dust-containing gas enters the filter bag filter area of the box. Most of the dust is trapped on the outer surface of the filter bag, and clean gas passes through the filter material and enters the inside of the filter bag. , And then discharged from the air outlet. The cage inside the filter bag is used to support the filter bag and prevent the filter bag from collapsing. At the same time, it helps to remove and redistribute the dust cake.

The filter bags are the key elements which determine the dust collecting efficiency and working temperature. Renewal of bags creates major cost in maintaining bag-house. So, the lifetime of qualified bag can last from two years to six years underthe condition of reasonable usage.

We believe that high-quality filter bags must have the following properties:

1. Selecting suitable filter material can stabilize low pressure loss operation: it can filter at high speed and high dust collection efficiency:
2. The result of reasonable design should meet the requirements of filtering and dust removal of the matching dust collector, which requires easy installation, reliable sealing, easy dust removal and avoiding wear as much as possible;
3. Advanced sewing technology meets the design requirements and reserves heat shrinkable dimensions according to the characteristics of the filter material.
4. Correct installation can ensure the reliability of the filter bag dust removal and prevent sudden abnormal conditions:
5. Use the filter bag reasonably and correctly, the life should be 2-5 years:
