1. A dust collecting filter for the filtering of gas containing solid particles, comprising:
a first and a second inlet plenum for receiving said gas containing solid particles;
a plurality of collateral inlet channels each having opposite first and second input extremities respectively connected to
the first and second inlet plenums to receive said gas therefrom;
a plurality of outlet channels each having a shared filtering boundary with at least one of said inlet channels, said filtering
boundaries allowing said gas to flow from said inlet channels to corresponding outlet channels while substantially retaining
the solid particles from said gas in the inlet channels, each of said outlet channels having a first output extremity;
a first outlet plenum connected to the first output extremity of all of said outlet channels for outputting said gas therefrom;
and
cleaning means for cleaning the solid particles out of said inlet channels, said cleaning means comprising a reverse flow
apparatus for circulating pressurized gas backwards through said dust collecting filter, said cleaning means further comprising
first and second inlet valve means for sequentially blocking gas circulation through said first and second inlet plenums during
operation of the reverse flow apparatus.
