International Classification:

B01J 19/00
B23P 6/00

US Classification:

422600, 29888011, 422129

Abstract:

An after-treatment system includes a Selective Catalytic Reduction (SCR) catalyst or a similar aftertreatment unit or brick that may be inserted into the opened end of a sleeve. The aftertreatment brick includes a substrate matrix with catalytic material that extends between a first face and a second face. A mantle is disposed around the substrate matrix and extends between a first rim proximate the first face and a second rim proximate the second face. The mantel may include a overhang extension that extends the first rim of the mantle beyond the first face of the substrate matrix. To enable retrieval of the SCR catalyst from the sleeve, a retrieval feature is disposed on a readily accessible, inner surface of the overhang extension.

International Classification:

F01N 3/18

US Classification:

60274, 60301

Abstract:

An exhaust aftertreatment module is provided. The exhaust aftertreatment module includes a housing having a first end and a second end. The at least one inlet is disposed between the first end and the second end and is configured to introduce an exhaust into the housing. A mixing tube is disposed downstream of the at least one inlet. The mixing tube is configured to direct the exhaust towards the second end of the housing. The exhaust aftertreatment module further includes a single bank of Selective Catalytic Reduction (SCR) catalysts disposed at an oblique angle to a longitudinal axis of the mixing tube. The single bank of SCR catalysts is configured to receive the exhaust redirected from the second end of the housing.

US Classification:

422168, 2952501

Abstract:

An aftertreatment system and method treats exhaust gasses produced by an internal combustion process or a similar process. The aftertreatment system includes an aftertreatment module having a sleeve extending between a first end and a second end. One or more aftertreatment bricks are axially inserted into a sleeve opening disposed in the first end of the sleeve. To prevent the aftertreatment bricks from unintentionally exiting the sleeve, a captive ring is disposed around the first end of the sleeve as a loose fitting collar. The captive ring is restrained on the sleeve by a circumferential bead protruding about the first end. The captive ring can couple with a retention ring placed adjacent the first end. When coupled to the captive ring, a portion of the retention ring extends partially across and blocks the sleeve opening, preventing the aftertreatment brick from exiting the sleeve.
