Sleeve filtration systems are used to separate particles from the air or flue gas stream. There are
usually hundreds of filters that are arranged in rows. When the filters become clogged, the increase
in differential pressure between the inlet and outlet streams initiates sequential cleaning of the
individual filter rows.
The analytical system at the outlet of the filtration system monitors the increase in dust
concentration due to the holes created on the worn filters, which appear just after the cleaning cycle
of the respective filter series, and getting soon covered by the dust deposit. In this way, it is possible
to significantly extend the service life of the bag filters.
Due to the capture of the emerging problem in an embryonal stage, it is possible to replace the
filters during the planned service shut down – chance of a filter break is practically completely ruled
out. In addition to the quality of the filter material disintegration, the system also warns of problems
with the activation of cleaning of some series of filters.
Special function is monitoring of blow-back valve leakages. Leaking air costs are in magnitude of
ten thousands euros yearly.
