Static gas mixer

摘要

The present invention is directed to an apparatus for mixing gaseous mixture components. The present invention likewise relates to a correspondingly applied method and to the use of an apparatus according to the invention for mixing components of the exhaust gas of internal combustion engines with a reducing agent and to a correspondingly designed reactor.

主权项

1. An exhaust system for treating an exhaust gas, comprising
a static mixer for mixing components in a gas flow, and a catalytic converter for subjecting the gas flow to a catalytic reaction, wherein the static mixer comprises:
a housing in which there is situated at least two baffle plates arranged one behind the other in a gas flow direction, both baffle plates having at least two eccentrically arranged holes,wherein the holes of the upstream baffle plate and the holes of the downstream baffle plate are offset from one another,wherein the holes of the upstream baffle plate are situated on one half of the upstream baffle plate, whereas the holes of the downstream baffle plate are situated on one half of the downstream baffle plate, with the one half of the downstream baffle plate having the holes situated thereon being an opposite half from the one half of the upstream baffle plate having the holes situated thereon, and the static mixer is positioned upstream of the catalytic converter in a flow path for the gas flow through the exhaust system.
