Exhaust mixing assembly

摘要

An exhaust treatment component including a mixing assembly located within a housing. The mixing assembly includes a decomposition tube having a first end and a second end, the first end being configured to receive the exhaust from the inlet and being configured to receive a reagent exhaust treatment fluid; a flow reversing device disposed proximate the second end, the flow reversing device configured to direct a mixture of the exhaust and reagent exhaust treatment fluid as the mixture exits the second end of the decomposition tube in a direction back toward the first end, the flow reversing device including a plurality of deflecting members for swirling and intermixing the exhaust and reagent exhaust treatment fluid; and a swirl arrester device configured to eliminate the swirling of the exhaust and reagent exhaust treatment fluid after exiting the flow reversing device.
