<p>PURPOSE:To automatically repeat capture and combustion-removal of fine particles by a method wherein a heater for heating filter medium which are operated by a pressure difference between an inlet and an outlet is installed in the exhaust gas filter in which filter medium for Diesel engine are filled up. CONSTITUTION:The filter medium 24 is filled up and the heater 26 for heating the filter medium in the exhaust gas filter. The heater 26 is operated by the pressure difference between the inlet 20 and the outlet 22. When fine particles are accumulated in the filter medium 24 and stopped up with meshes, contact points 40, 42 are closed by the pressure difference in a pressure switch 32 through a diaphragm 34. For this reason, the heater 26 is heated and the fine particles are burnt. Thus, the fine particles are automatically be captured and combustion-removed.</p> |
