Apparatus and process for filtration of particles contained in exhaust gas

摘要

The device has an electrostatic filtering cell (1) with a filtering unit (3) having an external electrode (5) made of porous material. The electrode permits an exhaust gas and pile of agglomerated particles to pass to a mechanical collector (29). The collector has a cylindrical portion (30) extended by a conical portion (31) opened into a recuperator container (33) having a heater cable (34) for eliminating the pile. Independent claims are also included for the following: (A) an assembly for filtering particles of the exhaust gas comprises several filtering and agglomeration devices (B) a method for filtering particles of exhaust gas of the motor vehicle.
