The installation further comprises: a first shutter in each inlet; and dust-removal manifold connected to the bottom of each cell via a dust-removal passage in which a second shutter is provided; and means for establishing a backflow of gas through each cell. For filtering, the first shutter is open and the second shutter is closed. For unclogging the first shutter is closed and the second shutter is open, and the backflow means unclog particles and remove them.
