EXHAUST EMISSION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress the invasion of a liquid-phase water generated in an exhaust gas route into a high-tension treatment part.

SOLUTION: This exhaust emission control device comprises the high-tension treatment part 40 in the exhaust gas route of an internal combustion engine. The device comprises a water drain pipeline 4 connecting a recovery port 2 disposed in the exhaust gas route on the outside of the high-tension treatment part 40 to an exhaust port 3 disposed in the exhaust gas route on the downstream side of the high-tension treatment part 40. A liquid-phase moisture recovered through the recovery port 2 is discharged from the exhaust port 3 into the exhaust gas route through the water drain pipeline 4.
