GAS/LIQUID MIXING DEVICE FOR EXHAUST AFTERTREATMENT |
| 摘要 |
A mixing device for an exhaust gas conduit comprises a first, inner sleeve having an upstream end, a downstream end and an inner passage extending therethrough having a diameter “D”. A deflector fin is formed in the first, inner sleeve and extends into the inner passage. A second, outer air-gap shell has an upstream end, a downstream end and a central portion having a diameter “D1” that is larger than the diameter D of the first, inner sleeve. The inner sleeve is disposed in the second, outer air-gap shell and the upstream and downstream ends are sealingly fixed to the first, inner sleeve to define an air-gap about the portion of the first, inner sleeve in which the deflector fin is formed. |

1. A mixing device for an exhaust gas conduit comprising:
a first, inner sleeve having an upstream end, a downstream end and an inner passage extending therethrough having a diameter “D”; a deflector fin formed in the first, inner sleeve and extending into the inner passage; a second, outer air-gap shell having an upstream end, a downstream end and a central portion having a diameter “D1” that is larger than the diameter D of the first, inner sleeve, wherein the inner sleeve is disposed in the second, outer air-gap shell and the upstream and downstream ends are sealingly fixed to the first, inner sleeve to thereby define an air-gap about the portion of the first, inner sleeve in which the deflector fin is formed. |
