出ガス後処理装置。 Particulate matter is captured by a particulate trap provided in the exhaust passage, an incineration means for incinerating the particulate matter is provided opposite to the particulate matter trap, and exhaust flow velocity information in the exhaust passage is detected by a hot wire anemometer. In the exhaust gas after-treatment device, the controller calculates the amount of particulate accumulated on the particulate trap in accordance with the exhaust gas flow velocity information in the exhaust path and drives the incineration means. 1. An exhaust gas post-treatment device, wherein a temperature sensor that outputs information is attached, and the controller corrects the particulate accumulation amount information according to the exhaust gas temperature information.
