What is the function of bag filter?

The Bag Filter is a dust control device whose purpose is removing the dust contained in the exhaust gases from industrial process. It is applied to the various applications with different temperature and type of gasses by selecting the filter media accordingly.

Where is bag filter used?

A bag filter, also known as baghouse filter, fabric filter, is used in industries as air pollution controlling device and Dust Collector.

What is bag type filter?

A baghouse, also known as a baghouse filter, bag filter, or fabric filter is an air pollution control device and dust collector that removes particulates or gas released from commercial processes out of the air.

How do you calculate bag filter capacity?

First calculate the total cloth area of your collector by calculating the total filter area of each filter (bag diameter x 3.14 x length ÷ 144 [for number of inches in a square foot] = filter cloth area) and then multiply that figure by the total number of bags in the bag type dust collector.

How do I choose a bag filter?

Criteria to consider when choosing bag filtration technology (…

  1. Characteristics and size of particles or solids to be removed (absolute versus nominal)
  2. Process conditions (flow rate, pressure, temperature)
  3. Filter media types.
  4. Considerations for filter housing choice.

What is the minimum air-to-cloth ratio for bag filter?

For most laser cutting applications, manufacturers should look for an air-to-cloth ratio between 1:1 and 1.6:1. Processes that produce heavier particulate loads—thicker materials, continuous production or higher velocity—may need even lower ratios, between 0.5:1 and 0.75:1.

What is pulse jet bag filter?

A pulse jet bag filter, also called a pulse jet baghouse or pulse jet dust collector, is a self-cleaning dry filtration system. The pulse jet dust collector cleaning system removes particulate matter and dust from the surface of internal filter media with bursts of compressed air.
