浄化装置。 A honeycomb-shaped filter that collects exhaust particulate matter from a diesel engine; a plurality of heaters that are divided near one end surface of the filter and ignite the particulate matter that has been collected on opposing filter parts; and a plurality of heaters that are arranged between the heaters. and a plurality of insulators that support the heater and enable split arrangement near the filter end face of the heater, the exhaust gas flows from the filter to the heater when collecting particulate matter, and the exhaust gas flows from the heater to the filter when regenerating the filter for particulate matter incineration. In the diesel particulate waste purification device of the reverse flow regeneration method, a heat transfer plate having a large number of pores is inserted between the heater and the filter, and the heat transfer plate is located near the insulator. A diesel particulate purification device characterized in that the pores are formed at an angle so that their axes point toward the filter portion facing the insulator.
