Pretreatment for Baghouse Filters

In today’s post we will be breaking down different fabric treatments for baghouse filters and how these pretreatment processes effect your filter medium.

 

  • Calendering: High pressure pressing of the fabric by rollers to flatten or smooth the material.
  • Napping: This is the scraping of the filter surface across metal points or burrs on a revolving cylinder.
  • Singeing: This is done by passing the filter material over an open flame, removing any straggly surface fibers.
  • Glazing: High pressure pressing of the fiber at elevated temperatures.  The fibers are fused to the body of the filter medium.
  • Coating: Involves immersing the filter material in natural or synthetic resin such as polyvinyl chloride, cellulose acetate, or urea-phenol.

 

Some of the results and reasons to use these pretreatments are:

 

  • Calendering: Result is that it flattens, smooths or decorated the filter medium.  This can increase surface life, dimensional stability, and provides a more uniform fabric surface.
  • Napping: The result is that it raises surface fibers, which can provide extra areas for interception and diffusion.
  • Singeing: Removes straggly fibers and provides a uniform surface area.
  • Glazing: Fibers are fused to the filter medium as a result.  This improves mechanical stability.
  • Coating: This helps to lubricate woven fibers.  Coating helps provide high temperature durability as well as chemical resistance for various fabric material.

 

 

 

Filter Bag Construction

In today’s post we’ll be going back to the basics of the dust collector industry and filter bags. We’ll be diving into filter construction to help us build a foundation of better understanding, or for those who have been in this industry for a while, a refresher course on the basics!

 

Filter Construction:

 

Filter bags used in the industrial dust collection industry can be made of woven or nonwoven materials.  Nonwoven materials can further be divided as felted or membrane.  Most bags are either completely or partially made by weaving since nonwoven fabrics are generally attached to a woven base called a scrim.  Woven filters are made of yarn with a definite repeated pattern.  Felted filters are composed of randomly placed fibers compressed into a mat and attached to loosely woven backing material.

 

A membrane filter is a special treatment where a thin, porous membrane is bonded to the scrim or support fabric.

 

  • Woven Filters: Generally used with low energy cleaning systems such as shaker or reverse air baghouses.
  • Felted Filters: Usually used with higher energy cleaning systems such as pulse jet dust collectors.
  • Membrane Filters: Developed in an effort to achieve high efficiency particle capture and to handle flue gas conditions where high moisture resulting high pressure drop problems frequently occur.
