The Benefits of Fabric Bag Filters
Bag filters are among the best ways of filtering dust and particulate matter from gas streams produced from the exhaust of industrial processes. It is a simple yet effective technology that only needs fabric bags to take care of the filtering work. The parts of this filtration system are cheap to obtain, which makes it the most cost-effective option for most industrial installations. It is commonly used for hot gas filtrating.
There are different types and forms of these filtration bags. There are also different ways on which the bags are arranged and utilized, to sure that at each turn, there is continued filtration, and that even when the bags get dirty, the filtration system still performs as expected. It also has a way of capturing all the particles while still working, with no need for a separate bag for storing all that material.
A simple bag filter shall have hanging bags through which the gas shall pass. The nags will thus choke out the dust particles while allowing the gas to pass through its fibers. As the material traps more particles in its fibers, it becomes more efficient in doing the filtration work. As the collected dust rubs against the fabric of the bags, it shall create an electrostatic charge. This charge shall thus attract more duct to the collection, which makes for an even more efficient filtration system. This process shall continue until the point when it is only trapping the dust without allowing most of the gas to pass through. This shall thus call for a change of the bags as the used ones get cleaned.
There are more complex systems in which there are dust collector bags in use. This ensures that at any point in the filtering cycle, there shall be parts of the bags that are not in use. The unused parts will be getting cleaned, and ready for their rotation into the filtration path. The collected dust is usually blasted off it using compressed air into waste bags.
If you can get such as a system that has the self-cleaning mechanisms in place, you shall realize greater efficiency. Such systems are especially needed where there is a large volume of gas being provided at all times, which makes it difficult for the system to be shut off for cleaning. There shall need to be a way for the cleanup to continue at the same time the hot gas is flowing and getting cleaned. The only time the system can be shut down is when the bags have gotten too worn out.
