Catalytic exhaust gas treatment apparatus
Abstract
Abstract A CATALYTIC APPARATUS FOR PURIFYING GASES, E.G. THE EXHAUST GAS OF AN INTERNAL COMBUSTION ENGINE, IN WHICH A UNITARY, CATALYTIC ELEMENT HAVING GAS FLOW PATHS THERETHROUGH, IS SECURED WITHIN A SURROUNDING CASING BY AT LEAST ONE END FLANGE, PREFERABLY TWO END FLANGES, A RESILIENT, FLEXIBLE MEMBER SURROUNDING SAID CATALYTIC ELEMENT, AND AT LEAST ONE SURFACE PROJECTING INWARDLY FROM THE INTERIOR WALL OF THE CASING AND IN CONTACT WITH THE RESILIENT, FLEXIBLE MEMBER. ROTATION OF THE CATALYST IS PREVENTED BY ONE OR A PLURALITY OF SUCH SURFACES, PREFERABLY AT LEAST THREE. WHEN USING A PLURALITY OF THESE SURFACES IT IS PREFERRED THAT AT LEAST TWO OR AT LEAST THREE BE SPACED-APART FROM EACH OTHER BY A LEAST ABOUT 90* WITH RESPECT TO THE CENTER OF THE CASING. LONGITUDINAL MOVEMENT OF THE CATALYST IS PREVENTED BY THE FLANGES AND FURTHER MOVEMENT OF THIS TYPE CAN ALSO BE COUNTERACTED BY PROVIDING A RECESS IN THE EXTERIOR SURFACE OF THE CATALYTC ELEMENT OR AN INWARDLY PROJECTING SURFACE ON THE INTERIOR WALL OF THE CASING, AND IN CONTACT WITH THE RESILIENT, FLEXIBLE MEMBER.
