Self-cleaning bag filters for high temperature dust, fumes and soot
DUSTdown® High Temperature is an extremely high-efficiency, self-cleaning filter with an online automatic cleaning system, which uses compressed air jets in Reverse Jet mode. This bag filter has been designed by Tecnosida® to face the specific problems related to the treatment of emissions deriving from:
The inlet of the air to be treated is located in the lower part of the dust collector. The flow passes through a pre-abatement chamber to allow the coarser dust to precipitate, thus protecting the filter from excessive dust loads. After this first phase, the flow passes through the filtering elements; the result is the particulate separation. Dust is retained on the outside of the bags and it is then precipitated into the lower part of the filter where the hopper conveys it to the collection or transport systems. These systems can be of different types depending on the needs of the production sector: collector, star valve, clapet valve or channel/ducted screw, or a pneumatic conveying system.
The filtering fabric is kept perfectly efficient thanks to automatic cleaning cycles, managed on the basis of the pressure drop reading. This manufacturing solution ensures a limited consumption of compressed air and a longer lifetime of the bags.
Extremely important: emissions deriving from the combustion of solid biomass are characterised by a high level of acidity which, over time, leads to the corrosion of the metal parts of the filter. For this reason, our DUSTdown® High Temperature filters are equipped with an automated injection system of basic substances (lime, bicarbonate or other substances) that abate the acidic component of the fumes, thus preserving the internal structure of the bag filter and its operation.
The presence of acidic substances and water vapour implies the possible development of acidic condensation, which must be avoided even during start-ups and shutdowns by means of appropriate technologies.
