Exhaust gas particles e.g. pollutant component, filtering and eliminating device for motor vehicle, has module collecting particles accumulated by particle filter, where potential difference between electrodes produces ionization of gas

The device has a collection module (12) that collects particles accumulated by a particle filter which is constituted by an electrostatic accumulation module that traps and accumulates the particles in the exhaust gas of an internal combustion engine. A potential difference created between the inner...

Beschreibung
Zusammenfassung:	The device has a collection module (12) that collects particles accumulated by a particle filter which is constituted by an electrostatic accumulation module that traps and accumulates the particles in the exhaust gas of an internal combustion engine. A potential difference created between the inner and outer electrodes induces the presence of an electric field in an axial passage so as to produce a partial or total ionization of the gas existing between the electrodes. A cathode (30) has a cover (33) and a bottom (32) for the collection of accumulated particles. Ce dispositif de filtrage et d'élimination de particules contenues dans un gaz d'échappement d'un moteur à combustion interne de véhicule automobile comprend un module d'agglomération électrostatique et un module (12) de récupération d'amas de particules agglomérées lors du passage des gaz d'échappement à travers le module d'agglomération.Le module de récupération comporte au moins une première électrode (31) formant anode et au moins une deuxième électrode (30) formant cathode s'étendant dans un champ électrique transversal, l'électrode formant cathode comprenant une surface (32) de réception de particules agglomérées déviée sous l'action du champ électrique formé entre les première et les deuxième électrodes qui débouche dans un volume de réception des particules.
