How to extend the life of dust filter bag?

March 15, 2024
  1. Selecting the Appropriate Filter Material: Choice the high quality Qingdao Star Machine’s filter bag material should be based on factors such as gas temperature, chemical properties, particle size, weight, shape, filtration speed, cleaning method, emission concentration, and the operating system of the dust collector. For example, needle felt is commonly used in pulse jet bag filters, while woven fabric is suitable for compartment reverse blow bag filters or mechanical shaking bag filters.

  3. Designing with Rational Structure: The structure of the filter bag should be compatible with the dust collector, meeting the requirements of filtration and cleaning while ensuring ease of installation and reliable sealing. For instance, the outer filter-type synthetic fiber filter bag should have a loose fit with the frame, while the outer filter-type glass fiber filter bag should fit tightly with a small-spacing vertical ribbed frame.

  4. Utilizing Sophisticated Sewing Techniques: Qingdao Star Machine’s durable filter bags should be technically advanced, with dimensions that meet design requirements, allowance for thermal shrinkage, and proper stitch spacing to avoid issues such as skipped stitches or broken threads. Additionally, the filter bags should be free from defects such as holes, yarn skips, and stains, and should be protected from damage or moisture during storage and transportation.

  5. Employing Correct Usage Methods: During installation, the mouth of the filter bag should be securely sealed and fixed to the perforated plate, ensuring that the bag hangs vertically below the plate and that adjacent bags do not collide with each other. Regular cleaning and maintenance of the dust collector, as well as timely removal and replacement of bags, are also crucial to prevent excessive wear and tear.

  6. Controlling Filtration Airflow Velocity: Excessive filtration airflow velocity can increase the load on the dust filter bags, resulting in higher filtration resistance and shortened lifespan. Therefore, it is essential to adjust the airflow velocity to an appropriate range based on actual conditions.

  7. Adjusting Appropriate Blowing Pressure and Pulse Width: For newly replaced filter bags, the injection pressure should be controlled within an appropriate range and adjusted accordingly as the bags operate over time.
