A typical bag filter has a dimension of 592 mm x 592 mm and consists of 4 to 12 parallel bags. The length and depth of the bag filter varies from 300 mm up to 900 mm. Bag Filter media efficiency varies from very low (coarse filter) to very high (fine filers). The Bag filter material is made of glass or polymer fibers of different thickness or number of layers, depending on the required filter performance. | |||
A prime example of the ways in which hot gas emitting applications can contain highly risky levels of contaminants and pollutants: cremation. The bacteria and possible infections present in a dead body are many, varied and all basically nasty. You can't just burn a corpse and have the smoke wander around unscrubbed. The use of bag filters benefits a crematorium (and anyone who lives anywhere near one) by operating with 100% efficiency as part of a bespoke system, which can remove all harmful particles from the gas flow (i.e. the smoke) before it exits the smoke stack. | |||
==Benefits== | |||
This benefit is doubled when you start to take known infections into account: any bodies cremated in a hospital or controlled environment are burned purposely to prevent a known infection or substance from transmitting into the general population. At this level of risk, a properly built and completely reliable bespoke filtering system can quite literally be a barrier between life and death, between successful containment and catastrophe. In this case, in tandem with the installation and use of the whole filtration system, the use of bag filters benefits the entire human race: without them, it simply wouldn't be possible to control the effluents that result from burning toxic or bio hazardous materials. There are some other benefits of bag filters as compared to other sorts of filters, too - a bag filter captures the particles it is taking out of a gas stream, which means that the collection mechanism and disposal unit for those particles are one and the same thing. The bag filter, when full, is simply safely removed and replaced with a new one. That's the primary way in which use of bag filters benefits a company over use of, say, wet filters or straight ceramic ones. | |||
