Method and apparatus for regenerating a filter

摘要

The present disclosure refers to a method for regenerating a filter (30; 300) adapted to remove particulate material (120) from a gas (40). The disclosed method comprises at least producing at least one electric arc discharge pulse (130; 135; 140), the at least one electric arc discharge pulse (130; 135; 140) being adapted to generate at least one pressure wave so that the particulate material (120) is being dislodged from the filter (30; 300). In addition, the disclosure refers to a filter regenerating arrangement and a diesel particulate filter (30, 300).
