Fabric filters are very important separation facilities in any industrial set up since they help in the separation of dust from the dusty gases. They normally make this separation through filtration. Introduction of the dust-laden gases into the bag houses usually takes place, and the fabric filters will trap the dust particles present in the gas. Very fine particles of dust are easily filtered out, and hence the separation has a high degree of efficiency of about ninety-nine percent. At times woven cotton or felted cotton is used in making the fabric filters. Some industries use synthetic or glass-fiber material which is enclosed in a glass tube. The characterization of the baghouses is based on the cleaning methods used. Such methods include shaking, reverse air, pulse jet, and sonic methods.
You need to use the most suitable fabric filter in your industry and for you to enhance this, always buy a well designed one. It is at times advisable to buy from reactor designers who have a wide experience in making such fabric filters by making the best optimization according to your industrial rate of dusty gas separations. In this article, I will equip you with informative tips which will aid you in arriving at the most suitable fabric filter. To begin with, select that American fabric filter which has the design which will handle the number of dusty gases you are dealing with. A good reactor designer will, first of all, assess the approximate amount of gases you normally subject to separation and make the best baghouse and fabric filters which suits you best.
Secondly, buy a fabric filter which can overcome corrosion. Some gases going to the filter are chemically acidic and therefore if you should go for that fabric filter which is resistant to such corrosion by chemicals. A fabric made of glass filters will be the most suitable for you in as far as corrosion is concerned. Polyester and Teflon are at times the most appropriate materials in making the fabric filters. This will translate into longer service to your industry and hence save you more money.
Lastly, go for that fabric filter which is not affected by the extreme temperatures which the dusty gas may have. Sometimes the removal of gases may take place after the stream have been subjected to my high temperatures and therefore in such a case, consider using that a robust fabric filter even at an extremely high temperature. Therefore select a fabric filter which will not reduce its performance at varying temperature of the dusty gases.
