摘要： PROBLEM TO BE SOLVED: To perform the combustion regeneration of a filter at an optimum power consumption by grasping a state of particulates adhered to a filter in advance and to prevent melt down of two filter through automatic suspension of the combustion regeneration when an accumulated amount is too high to effect regeneration. SOLUTION: This purifying device is provided with pressure sensors 1a and 1b arranged at least at one of the regions between an air blower 7 to feed a constant flow rate of regenerating air and an electric heater 4 or between the electric heater 4 and a filter 3. Based on a value of at least one spot of the pressure sensors 1a and 1b, a collected amount of particulates adhered to the filter 3 is estimated. According to the estimated value, the time for continuity to the electric heater 4 and a blowing time of an air blower 7 are controlled. When particulates are judged excessively adhered to the interior of the filter 3, regeneration is suspended and cracking and melt down of the filter 3 due to abnormal combustion are prevented from occurring.

摘要： PROBLEM TO BE SOLVED: To suppress occurrence of a crack to a filter and dissolve melting loss so as to improve durability, by making air to serve as a heating medium, and blowing this heated air to the filter under the condition of a turbulent flow agitated. SOLUTION: To shut off an engine exhaust gas flow (y), and a channel is secured is for a secondary air flow (x) for refreshing combustion, and exhausts gas of the secondary air flow (x). After that, the refreshment of a filter 60 in which particulates are collected, is started. Firstly, the secondary air flow (x) for refreshing combustion, is introduced from a channel piping 62 on the downstream side of the secondary air flow (x) for refreshing combustion. The secondary air flow (x) is heated by a heating part 61 such as an electric heater so as to be hot air. This hot air is turned into a slewing flow when passed through an agitating part 4 so as to be agitated and mixed to have equal heat, and blown to the filter 60. The filter 60 is equally heated however, the hot air is supplied to the filter 60 so as to be equally heated under a condition that dispersion of temperature is corrected and controlled by passing the hot air through the agitating part 4.
