Abstract

Una cartuccia filtro (23) comprende una parete (24) formata di un materiale poroso ed elettricamente conduttivo. Due elettrodi di opposta polarità (29, 31) sono collegati con due porzioni (32, 33) della parete (24), le quali sono disposte in posizione reciproca tale che, fornendo energia elettrica ai due elettrodi (29, 31), si provoca un passaggio di corrente lungo una zona oblunga (36) della parete (24) stessa, determinando la combustione dei prodotti residui della combustione dei gas presenti in tale zona (36), ed innescando così la rigenerazione della cartuccia (23). Il materiale poroso è preferibilmente formato da fibre o polveri metalliche parzialmente sinterizzate e/o catalizzate.(Figure 2 e 3)A filter cartridge (23) comprises a wall (24) formed of a porous and electrically conductive material. Two electrodes of opposite polarity (29, 31) are connected with two portions (32, 33) of the wall (24), which are arranged in a reciprocal position such that, by supplying electrical energy to the two electrodes (29, 31), it causes a passage of current along an oblong area (36) of the wall (24) itself, causing the combustion of the residual products of the combustion of the gases present in that area (36), and thus triggering the regeneration of the cartridge (23). The porous material is preferably formed of partially sintered and / or catalyzed metal fibers or powders (Figures 2 and 3)
