Patent ID: 7625433

Claim:
A method for cleaning a particle filter comprising: feeding in a direction of filtration a gaseous stream laden with at least one of pollutants and particles to a particle filter that operates by at least one of a catalytic process and a filtration process and that comprises a filter medium; chemically converting or storing at least one of pollutants or particles in the particle filter such that a dust cake is deposited on the particle filter; wherein once the particle filter has been used for a specific period of time, applying a layer for increasing the through-flow resistance to the dust cake upstream of the filter medium in the direction of filtration; supplying energy in the form of at least one of convection, radiation or contact heat so as to make the layer for increasing the through-flow resistance virtually impenetrable to flow or impermeable; and carrying out a flushing process in a direction counter to the direction of filtration to detach filtrate or ash particles of the dust cake.
