Reverse-jet de-dusting filters for high temperature and biomass combustion emissions
DUSTdown® High Temperature is a very high efficiency self-cleaning mechanical filter, equipped with an automatic on-line cleaning system with a Reverse Jet of compressed air. It was designed by Tecnosida® to address the specific problems associated with treating emissions from solid biomass combustion (woodchips, wood, pellets, twigs, agricultural waste, rice husks, sunflower hulls and many others).
The air to be treated enters the lower part of the dust remover, passes through a pre-filtering chamber that allows the courser dust to precipitate, protecting the filter from excessive dust loads. The flow then reaches the filtering surface and passes through it with consequent realization of the separation of the particulate. The dust collected by the numerous sleeves precipitates to the bottom of the filter where the hoppers direct it to the collection system (cochlea, rotary star valve, clapet valve or screw with conduit/pipe) or automatic discharge.
The filtering surface is kept in perfect condition thanks to automatic cleaning cycles. These are managed on the basis of the filter pressure loss readings to limit the compressed air consumption and increase the lifetime of the sleeves.
Very important: Emissions from the solid biomass combustion are characterized by a high level of acidity which can lead to corrosion of the metal parts of the filter. For this reason, our DUSTdown® High Temperature is equipped with an automatic injection system of basic substances (lime, bicarbonate or other) that reduce the acid component of the fumes, preserving the internal structure of the filter and its functioning.
