EXHAUST GAS MIXING DEVICE

WIPO Patent Application WO/2016/186193

A1

[Problem] To provide an exhaust gas mixing device that can facilitate exhaust gas mixing with little increase in pressure loss. [Solution] The exhaust gas mixing device that is provided with gas mixers 1 into which combustion exhaust gas G, to which a reducing agent for reducing nitrogen oxides in the combustion exhaust gas has been added, is introduced is characterized in that: the gas mixers each have a gas flow path through which the combustion exhaust gas G flows with one of two parallel surfaces for a cuboid space 3 as a gas inflow surface and the other as a gas outflow surface; and the gas flow path has the gas inflow surface and the gas outflow surface divided into at least four symmetrical regions of identical surface area by lines (9a, 10a), (9b, 10b) passing through centers 7, 8 of the respective surfaces, and is provided with gas flow path dividing plates 6 (a - d) that guide the combustion exhaust gas G flowing into each region of the gas inflow surface to the various regions of the gas outflow surface in positions where the regions are each offset by one around a line segment L3 joining the centers of the gas inflow surface and the gas outflow surface.
