<p>PURPOSE:To improve durability and maintainability by jetting high pressure gas from a backwash nozzle to perform regeneration of a filter and partly receiving exhaust gas by a fine grain receiving part through a particulate incineration pipe and a discharge pipe so as to discharge an incombustible material to the outside of a system. CONSTITUTION:A particulate in exhaust gas, discharged from an engine 101, is captured and removed in each filter 104a, 104b. The particulate is accumulated in each filter 104a, 104b, when a circulation pressure drop is increased with a condition necessary for regeneration of the filters, these regeneration is performed alternately with the time shifted. That is, first an open-close valve 109a is closed, thereafter an electric drive valve 107a is opened for a predetermined time to inject high pressure air from a backwash nozzle 108a with the filter 104a backwashed. The wiped-off particulate is received by a receiving part 112a and incineration-processed in an incineration part 120a in which an igniting heater 121a is provided, and exhaust is discharged to an exhaust passage 102a via a solenoid valve 125a.</p> |
