したことを特徴とする排気ガス処理装置。[Scope of Claim for Utility Model Registration] A particulate trap for collecting particulates in exhaust gas is disposed in a cylindrical container, and on the upstream side of the particulate trap in the cylindrical container. A regeneration heater that burns and regenerates the particulate matter collected in the particulate matter trap is disposed opposite to the particulate matter trap, and a heat reflector provided with ventilation to reflect the radiant heat from the heater is provided on the upstream side of the particulate matter trap. The exhaust gas treatment device is provided with a regeneration air supply mechanism that supplies regeneration air to the particulate trap through the heat reflector and the heater in sequence, and the cylindrical container The regeneration air is guided from the upstream side of the heat reflector to the downstream side through the heat reflector. An exhaust gas treatment device characterized in that a portion of the heat reflector is guided to the heater and the particulate trap through the opening of the heat reflector.
