DEVICE FOR EXHAUST GASES CLEANING Russian patent published in 2017 - IPC F01N3/20 

FIELD: machine engineering.

SUBSTANCE: device (1) to feed liquid additives in exhaust gas flow (4) having a pipeline section (2) for exhaust gas flow (4) with an inlet end (3), an output end (5), a direct section (30) and a protrusion (17) with a hole (31) for mounting liquid additives feeder (7) on a straight section (30), with a protrusion (17) having a height (32) and length (33), and length (33) at least twice than height (32), at input end (3) and on output end (5) there is respectively at least one disk-shaped honeycomb body (6), central axis (34) of hole (31) is directed at one of honeycomb bodies (6), at least one of two honeycomb bodies (6) at input end (3) or on output end (5) are made cone-shaped, pipeline section (2) between disc-shaped honeycomb body (6) located at outlet end (5) and outlet end (5) has a flow alignment section (47), at which cross-section (53) of pipeline section (2) is at least partially offset. and disc-shaped honeycomb body (6) to which central axis (34) is directed, is disposed at an angle (36) to axis (26) of pipeline section (2).

EFFECT: invention improves the of input injected additive in the honeycomb body by optimizing the incidence angle.
