FIELD: gas industry.
SUBSTANCE: invention relates to device (10) for mixing of a waste gas flow with an additive, in particular with a reducing agent. Device (10) includes mixing pipe (14) for mixing of a waste gas flow with an additive. Device (10) includes first guiding pipe (12) for changing a direction of the waste gas flow, in particular, by 180°. First guiding pipe (12) is made with the possibility of supply of the waste gas flow to mixing pipe (14). First guiding pipe (12) includes fastening area (28) for installation of additive injector (30) on first guiding pipe (12). First guiding pipe (12) includes vortex-creating area (26) of a wall, located at an end of mixing pipe (14) and made for impart of vortex to the waste gas flow.
EFFECT: device (10) provides compact arrangement as first guiding pipe (12) is used for both creation of vortex at the end and accommodation of additive injector (30).
