器とを備えたことを特徴とする排気後処理装置。 The particulate matter in the exhaust gas discharged through the exhaust passage of the internal combustion engine is captured by a particulate matter trap, and the particulate matter is incinerated by supplying high-temperature gas from the upstream side of the particulate matter trap. The exhaust gas after-treatment device performs a regeneration process of the particulate trap, the exhaust gas passage being formed by dividing the exhaust passage upstream of the particulate trap into two parts, a trapping exhaust passage and a regeneration exhaust passage; a switching valve that selects one of the regeneration exhaust passage and the regeneration exhaust passage to communicate with the particulate trap; a radiator for discharging the heat of the exhaust gas flowing into the trap and making the temperature lower than that of the exhaust gas flowing through the regeneration exhaust path to the particulate trap; and a radiator for recovering the thermal energy radiated by the radiator. An exhaust aftertreatment device characterized by comprising an exchanger.
