Abstract
The present disclosure is directed to an after-treatment device. The after-treatment device may have a center plenum configured to be fluidly connected to an engine. The after-treatment device may also have a filter bank having a plurality of filter assemblies. Each filter assembly may have an inlet fluidly connected to the center plenum. The inlet may be oriented orthogonal to the center plenum. Each filter assembly may also have an outlet. Further, the after-treatment device may have an exhaust plenum fluidly connected to the outlet. The exhaust plenum may be oriented orthogonal to the outlet. The exhaust plenum may also have an outer wall disposed parallel to and located at a predetermined distance from the outlet.
Claims20
An after-treatment device, comprising:
- a center plenum configured to be fluidly connected to an engine;
- a filter bank having a plurality of filter assemblies, each filter assembly including:
- an inlet fluidly connected to the center plenum, the inlet being oriented orthogonal to the center plenum;
- and
- an outlet;
- and
- an exhaust plenum fluidly connected to the outlet, the exhaust plenum being oriented orthogonal to the outlet and having an outer wall disposed parallel to and located at a predetermined distance from the outlet.
A machine, comprising:
- an engine having a plurality of cylinders;
- a center plenum configured to receive exhaust from the plurality of cylinders;
- a first filter bank oriented orthogonal to the center plenum and configured to receive a first portion of exhaust from the center plenum;
- a second filter bank oriented orthogonal to the center plenum and configured to receive a second portion of exhaust from the center plenum;
- a first exhaust plenum oriented orthogonal to the first filter bank and configured to receive the first portion of exhaust from the first filter bank, wherein the first exhaust plenum has a first outer wall disposed parallel to and located at a predetermined distance from an outlet of first filter bank;
- and
- a second exhaust plenum oriented orthogonal to the second filter bank and configured to receive the second portion of exhaust from the second filter bank, wherein the second exhaust plenum has a second outer wall disposed parallel to and located at the predetermined distance from an outlet of second filter bank.
