BACK WASH RECONDITIONING DEVICE FOR DIESEL PARTICULATE FILTER

摘要

PROBLEM TO BE SOLVED: To reliably effectively and instantaneously back-wash and recondition the whole part of a particulate filter and not a part of it. SOLUTION: An impact air valve 10 is disposed in the downstream of a particulate filter 3 and shock wave from the impact air valve 10 blows down particles deposited on the particulate filter 3 in a particulate burning part 9 to burn them by the heat of a heater 8 in the particulate burning part 9.
