ス後処理装置。[Scope of Claim for Utility Model Registration] A particulate filter that collects particulate matter in exhaust gas emitted from a diesel engine, a heater that heats this particulate filter,
In an exhaust gas after-treatment device equipped with a blower that supplies air to a filter, when the temperature of the particulate filter is detected and the temperature of the filter is below a predetermined value,
Operate the blower and turn on the heater to supply heated air to the filter to preheat the filter, and after the preheating of the filter is completed, the supply of air is interrupted and the heater is preheated. The exhaust gas after-treatment device is further provided with a controller that operates the blower again after the completion of preheating of the heater to supply air and burn particulate adhering to the filter.
