| 摘要 |
<p>The invention relates to a method and the corresponding apparatus (1) for at least partially regenerating a used particulate filter (F), in particular a filter (F) for use in automobiles of the type commonly identified by the acronym FAP or DPF. A jet of a washing liquid, for example water, and a flow of a washing gas, for example air, are continuously fed to the particulate filter for the entire duration of the washing of the filter and simultaneously pass through the filter (F) in the opposite direction with respect to the direction in which the exhaust gases of the relative vehicle pass through the filter (F) when the filter (F) is in use. The water-air fluid is preferably bi-phase and the temperature of the air is comprised in the range 70÷90°C. The method allows used particulate filters to be completely or almost completely regenerated in about 20-30 minutes.
