Uses of Fabric Filter

 

The fabric filter is also known as the bag houses and is being commonly used in a lot of the industrial applications. They can operate the same with that of the vacuum cleaner. Those dust-laden gases can pass into the fabric bags where the particulates can be trapped into that of the fabric surface.

 

After the dust layer is being built up onto the filters, it is then being removed by simply blowing some high pressure air right back to the fabric, then reversing the flow of the gas or shaking that of the fabric.

 

The dust from that of the American Fabric Filter will then fall to the collection hopper from where it is removed. The layer of the dust that is accumulating into the bag is referred to as the dust cake. The fabric filters, then collect particles with the sizes that will range from that of the submicron to the several hundred microns in diameter at the efficiencies that will generally range from 99 or around 99.9 percent.

 

The particle laden flue gas will actually leave the boiler and that of the heat recovery unit and then enter the filter inlet plenum that in turn can distribute the gas to every fabric compartment for the needed cleaning. The outlet plenum can collect the cleaned flue gas from every compartment and then it directs to the induced draft fan and then to directly to stack. The inlet and also the outlet dampers are being provided which will allow the isolation of every compartment for the bag maintenance and cleaning.

 

The dustcake is being formed by the accumulation of that of the particulate into the bags all over the operating period. Once being formed, the dust collector socks provides most of the filtration, but impingement collection is actually the very effective on all of the larger particles and that of the sieving process collects all of the sizes of the particle and a dustcake to maximize that of the overall collection. As the dustcake will build the flue gas pressure drops will increase right across the fabric filter, so at this very point the bag are needed to be cleaned.

 

Lastly, the fabrics that are used in the bag houses can be readily made of the number of the different materials like for instance the paper, polyester, and the cotton. The filter bag selection will then depend in corrosive properties of those gases, particle size, and the temperature dust laden gas. The area of the filter bag is being decided by that of the air to cloth ratio that will determine the pressure drop and also the efficiency in the collection.
