COMPACT RADIAL EXTERIOR EXHAUST ASSISTED DECOMPOSITION REACTOR PIPE

摘要

Various embodiments provide for apparatuses and systems involving a reactor pipe configured to receive reductant from an injector into a flow of exhaust exiting an engine. The reactor pipe comprises an inlet portion, a plurality of louvers, an outlet portion, and a radial loop. The inlet portion is structured to receive the flow exiting the engine into the reactor pipe. The louvers are structured to alter a direction of the flow. Further, the radial loop is configured to extend between the inlet portion and the outlet portion and receives the flow of exhaust through the inlet portion. The radial loop also directs the flow of the exhaust toward the outlet portion and reduces the velocity of the flow of the exhaust such that the reductant has an increased amount of time to react with the exhaust.

1. A reactor pipe configured to receive an injection of reductant from an injector into a flow of exhaust exiting an engine, the reactor pipe comprising:
an inlet portion structured to receive the flow of exhaust exiting the engine into the reactor pipe; a plurality of louvers positioned proximate the inlet portion, the plurality of louvers structured to alter a direction of a flow of exhaust; an outlet portion in fluid communication with a selective catalytic reduction catalyst and structured to allow the flow of exhaust to exit the reactor pipe and enter the selective catalytic reduction catalyst; and a radial loop extending between the inlet portion and the outlet portion, the radial loop receiving the flow of exhaust through the inlet portion and directing the flow of exhaust toward the outlet portion, the radial loop configured to reduce the velocity of the flow of exhaust such that the reductant has increased time to react with the exhaust.
