- the invention relates to a device for the treatment of soot particles containing exhaust gas, which can be used in particular with a so-called electrostatic filter or electrostatic precipitator.
- the invention is preferably used in the treatment of exhaust gases of mobile internal combustion engines in the automotive sector.
- regular (multiple) discharge electrodes and collector electrodes are proposed, which are positioned in the exhaust gas line.
- a central spray electrode which extends approximately centrally through the exhaust pipe, and a surrounding jacket surface of the exhaust pipe as a collector electrode used to form a capacitor.
- the spray electrode for example, can be operated with a high voltage which is in the range of about 15 kV.
- corona discharges can be formed by which the particles flowing with the exhaust gas through the electric field are charged in a unipolar manner.
- the particles migrate to the collector electrode due to the electrostatic Coulomb forces.
- the collector electrode for example, is designed as a wire grid.
- the addition of particles takes place on the wire grid for the purpose of possibly combining the particles with other particles, so as to achieve an agglomeration.
- the exhaust gas flowing through the grid then tears the larger particle agglomerates again and leads them to classical filter systems.
- a device for generating an electric field in an exhaust system is to be proposed, which can be provided by simple means and known technologies as part of a series production.
- the device should be easy to integrate into an exhaust pipe, in particular so that a targeted alignment of the electrodes is made possible towards the desired electric field or the associated particle trap.

- the at least one electrode is formed with at least one metal sheet, the at least one electrode extends in the flow direction of the exhaust gas and all electrodes have in the flow direction of the exhaust gas before several jumps.
- This device is in particular a pole of an electrostatic filter. It is preferred that the electric field (possibly a pulsed) DC field is. In particular, voltages in the range of 10 kV to 30 kV [kilo-volts] can be generated.
- the exhaust system is in particular that of a mobile internal combustion engine, in particular that of a diesel engine of a motor vehicle.
- the region of the exhaust pipe, which is performed with a corresponding electric field, may optionally be electrically isolated, which may be realized in the axial direction of the exhaust pipe, as well as radially outward.
- the at least one electrode is positioned in the interior of the exhaust pipe, ie in the space through which the exhaust gas flows.
- the at least one electrode is electrically contacted with a power supply, for example by means of appropriate electrical conductors, connectors, solder joints, etc.
- an electrically encapsulated implementation of the power supply through the exhaust pipe is preferred.
- the electrode is formed with at least one metal sheet.
- a (sheet-like) strip of metallic flat material is understood as meaning a metal sheet which may be essentially smooth or flat, but it is also possible for the metal sheet to be structured, ie, for example. has a corrugation.
- the series production is already very advanced, so that here a precise design of similarly shaped metal sheets has already been implemented. This manufacturing knowledge can now be used to perform such metal sheets as electrodes and to use for generating a corresponding electric field.
- the metal sheet with corresponding contact conductors, electrical conductors, soldering points and the like is executed, so that possibly even with the use of insulating coatings or deposits for the metal sheet, a predetermined current path can be formed by the metal sheet itself.
- a predetermined current path can be formed by the metal sheet itself.
- correspondingly electrically conductive materials come into consideration here.
- a flat side of the metal sheet is arranged parallel to the flow direction of the exhaust gas.
- the metal sheet represents the smallest possible flow resistance for the flowing exhaust gas.
- the metal sheet is in particular of a material with a low ohmic resistance, which cumulatively or alternatively has only a low oxidation capacity.
- the metal sheet should preferably consist of a homogeneous material, so that a uniform field with a good ionizing ability is formed on the projections.
- the metal sheet preferably has a thickness of less than 0.1 mm, more preferably less than 0.065 mm, most preferably less than 0.035 mm.
- the at least one electrode extends in the flow direction of the exhaust gas. In other words, that means that the metal sheet is arranged to the flow direction of the exhaust gas, that it represents the smallest possible flow resistance.
- the flat side of the metal sheet is arranged in particular parallel to the flow direction of the exhaust gas.
- the at least one electrode has a plurality of projections in the flow direction of the exhaust gas.

- the metal sheet or the projections are arranged or aligned with respect to the exhaust pipe so that they have a uniform electric field towards a collector electrode, in particular a downstream particle trap result. It is particularly preferred that only one (single) metal sheet is provided, but which has a plurality of projections, each forming electrode tips. In particular, it is preferred that the at least one projection has a length of 15 mm [millimeter] to 20 mm [millimeter] in the flow direction, so that oscillation of the projections during operation is avoided.
- At least three projections are each formed at a distance from at least two adjacent projections, wherein the distances are substantially equal.
- the distances differ by no more than 10%.
- the distances are at least 10 mm, more preferably at least 30 mm, most preferably at least 50 mm.
- the projections on the metal sheet with a winding corresponding distance must be arranged to each other.
- the relatively large distances also prevent an (undesired) electric field from forming between the projections.

It is obvious that the electrode may need to be electrically insulated from the honeycomb body. If, for example, electrically insulating coatings are provided here, they can also serve as a basis for electrical conductors to the electrode, which are simply applied to this electrical insulating coating.
- the at least one electrode is followed by a particle trap in the flow direction of the exhaust gas.
- the here (directly) downstream particle trap serves as a kind of collector electrode.
- the soot particles which flow through the region between the at least one electrode and the particle trap are charged in the electric field positioned there and are finally deflected towards the filter material of the particle.
- the particulate trap is in particular a so-called open bypass filter in which there are no completely closed flow channels. Rather, the particle trap is formed with a metallic fleece and metallic corrugations in which openings, guide structures, etc. are provided.
- the guide structures form flow bottlenecks in the flow passages, so that the residence time or impact probability for soot particles in the interior of the particle trap is increased.
- the regeneration of such a particle trap is preferably carried out continuously based on the CRT method.
- the device z For example, an oxidation catalyst may be provided upstream in which nitrogen oxide is also oxidized to nitrogen dioxide, which then reacts with the soot in the particulate trap.

- the desired electric field 2 is formed between the electrodes 5 and the particle trap 11 following in the flow direction 8, in which the soot particles can agglomerate or be charged.
- the electrically charged particles then strike the particle trap 11, where they are preferably stored in or on the filter material and converted into gaseous constituents as part of a regeneration process.
- FIG. 2 now illustrates a variant embodiment of the device 1, wherein the electrodes 5 are again integrated in a honeycomb body 10.
- Shown here is a perspective view of a cylindrical housing 13, in which a plurality of at least partially structured (electrically inactive) metal foils (shown in white) and (electrically at least partially active) metal sheets (indicated in black) is arranged. Between the structures of the metal foils or metal sheets, passages are provided which are longitudinally passable and run essentially parallel to one another.
