Catalytic converter and catalyst element therefor
View Patent ↗An industrial catalytic converter and a removable catalyst element therefor wherein a solid extension is secured on the catalyst element such that, when the catalyst element is positioned in the converter housing, the solid extension will project into the element insertion channel of the housing in a manner effective to at least partially block the flow of exhaust gas around the catalyst element.
1. A catalytic converter comprising: a housing having a longitudinal flow passage; at least one catalyst element removably positionable in said housing across said longitudinal flow passage; an insertion channel projecting outwardly from said housing for insertion of said catalyst element, said insertion channel having an outer end spaced outwardly from said housing; and a cover removably positionable on said outer end, the improvement comprising a solid extension which is impervious to gas flow and is secured on and extends from said catalyst element such that, when said catalyst element is positioned in said housing, said solid extension will project into said insertion channel in a manner effective to at least partially block flow around said catalyst element through said insertion channel.
2. The catalytic converter of claim 1 wherein the improvement further comprises a sealing element attached to at least an outer portion of said solid extension for sealing against said cover.
3. The catalytic converter of claim 1 wherein:
said catalyst element has an outer periphery and
said solid extension is secured on and projects radially outward from a portion of said outer periphery.
4. The catalytic converter of claim 3 wherein the improvement further comprises a peripheral sealing element attached to and extending around said catalyst element and said solid extension.
5. The catalytic converter of claim 4 wherein said peripheral sealing element is a tape gasket attached peripherally around said catalyst element and said solid extension.
6. The catalytic converter of claim 3 wherein said catalyst element is substantially octagonal in shape.
7. The catalytic converter of claim 3 wherein said catalyst element is substantially circular in shape.
8. The catalytic converter of claim 1 wherein the improvement further comprises a plurality of said catalyst elements removably positionable in said housing across said longitudinal flow passage, each of said catalyst elements having a solid extension which is impervious to gas flow and is secured on and extends from said catalyst element for projecting into said insertion channel.
