ABSTRACT:
A system for filtering stack gases and the like comprising an in-feed exhaust duct and a pair of filter vat cleaners disposed on opposite sides of the in-feed exhaust duct and horizontally spaced therefrom. A track assembly extends horizontally above the in-feed exhaust duct and filter vat cleaners, and a carriage car carrying two horizontally spaced filter containers is mounted rollably on the track assembly for reciprocating movement therealong to alternately position one of the filter containers over the exhaust duct, and then the other over one of the two filter vat cleaners, in alternating sequence. Coupling means is provided for coupling the filter containers with the respective filter vat cleaners and the exhaust duct. An out-feed exhaust duct is positioned over the track assembly and carriage and is vertically aligned with the in-feed exhaust duct. Coupling means is provided for coupling the discharge exhaust duct to whichever of the filter containers is located therebelow, and in alignment with the in-feed exhaust duct. Means is provided for bypassing exhaust gases from the in-feed exhaust duct to the discharge exhaust duct when no filter container is positioned therebetween.
