ABSTRACT:
The present disclosure relates to a pulse cleaner for cleaning a diesel exhaust treatment device. The pulse cleaner includes a cabinet, a diesel exhaust treatment device mount positioned within the cabinet for mounting the diesel exhaust treatment device during pulse cleaning, and a collection filter positioned within the cabinet for collecting material displaced from the diesel exhaust treatment device during cleaning. The pulse cleaner also includes a pulse generator for generating pulses that are each directed at a majority of a face of the diesel exhaust treatment device when the diesel exhaust treatment device is mounted at the diesel exhaust treatment device mount. The pulse generator includes a pressure tank for accumulating pressurized air, and a valve arrangement that flushes the pressurized air from the tank. A pulse of air for cleaning the diesel exhaust treatment device is generated each time the tank is flushed.
