<p>PURPOSE:To regenerate a particle capturing device satisfactorily in the stage of regenerating the same by allowing electric heaters to evolve heat and decreasing the flow rate of waste gases. CONSTITUTION:If two electric heaters 28, 29 in the end face part on the upper stream of the particle capturing bed 27 of a particle capturing device 23 in a regenerating method for the particle capturing device in a recirculator for waste gases of diesel engines are allowed evolve heat, captured particles burn, and at this time the flow rate of the gases flowing through the recirculating flow passage for the waste gases is decreased by controlling a control valve for recirculation of the waste gases so that only the oxygen required for combustion is supplied. Thus the particle capturing device is regenerated satisfactorily.</p> |
