<p>PURPOSE:To prevent melting loss of a reactivated filter in the side of later starting side by differentiating conditions for reactivating a duel filter between the early starting side and the later starting side in a dual filter type exhaust particulates remover for carrying out simultaneous collection and alternate reactivation. CONSTITUTION:After bifurcated into bifurcated tubes 2A, 2B at a bifurcating part (a), the exhaust tube 2 of an internal combustion engine 1 is connected to a muffler 6 through a confluent part (b). Filters 5A, 5B are stored in the casings 3A, 3B provided in the middle of the bifurcated tubes 2A, 2B. The reactivation timing of the filters 5A, 5B is judged by a control circuit 100 based on the upper and lower pressure of the filter 5A, 5B as detected by a differential pressure sensor 10, while particulates electrified to electric heaters HA, HB and are thus collected thereby are incinerated. The reactivation conditions of the filters 5A, 5B are differentiated between the early starting side and the later starting side. Melting loss is thus prevented from being generated in the reactivated filters 5A, 5B in the later starting side.</p> |
