Definitions
- the invention relates to a plasma soot filter according to the preamble of claim 1.
- a soot filter is the subject of DE 100 57 862 Cl.
- an electrode is attached to each of its edges in a filter channel in order to generate surface sliding discharges.
- the electrodes required for plasma generation can either be embedded in the filter material or applied to the filter material in such a way that in any case between an electrode connected to high voltage. trode and the ground electrode is connected to a layer of high dielectric strength. Due to the embedding of the electrodes described there, such surface sliding discharges can only be generated on both sides of the cell walls, while the soot is only deposited on one side. This means that the specific energy consumption for regeneration is twice as high as is actually required.
- Electrodes exposed to the exhaust gas are exposed to erosion processes due to the contact with the exhaust gas, which can be intensified by gas discharge processes. These erosion processes can not only affect the service life of the electrodes in particular, but also the service life of the ceramic due to the formation of metal oxides.
- Another disadvantage is that the large number of electrodes - four per inlet channel - significantly increases the size and weight of the plasma soot filter compared to a conventional filter.
- a wall flow filter consisting of mutually closed elongate channels with any cross section is created, the walls of which are covered with soot are regenerated by surface sliding discharges.
- the surface sliding discharges now burn due to the arrangement of the electrodes embedded in the filter material and thus protected against erosion, preferably on the inlet side of the filter covered with soot.
- only two electrodes are required for generating the surface sliding discharges in the given geometry with double-beam symmetry per inlet channel.
- the starting point of the invention is a wall flow filter consisting of elongated channels with a square cross section arranged in a matrix.
- the channels are mutually closed along a row or a column, so that inlet and outlet channels alternate.
- the electrode arrangement according to the invention ensures that the distribution of the electric field in the individual cells of the plasma soot filter enables the ignition of non-thermal surface sliding discharges in individual cells.
- the dielectric properties of the wall material of the ceramic soot filter which concentrates the field in cavities between the electrodes, are used.
- a reduction in the number of electrodes per inlet channel from 4 to 2 does not result in a deterioration in the electrical field distribution with regard to the generation of surface sliding discharges.
- What is essential for this is the arrangement of the electrodes on diagonally opposite edges of the square channel cross section, it being necessary that adjacent inlet channels must be connected in the same polarity via their edges not provided with electrodes.
- FIG. 1 and FIG. 3 cross sections of plasma filter elements with inlet and outlet channels and associated electrodes
- FIGS. 1 to 5 and 7 to 12 described in detail in DE 100 57 862 C1 wall-flow filters made of ceramic material made of mutually closed elongate channels with a special square cross-section, in the corner points of which electrodes are installed, are shown.
- FIG. 1 shows in cross section such an electrode arrangement in a plasma filter element of a conventional type with four electrodes per channel embedded in filter material.
- an inlet channel is designated 10 and an outlet channel 20.
- Inlet duct 10 and outlet duct 20 are separated by porous walls 30 made of specific ceramic material. Electrodes are installed in the walls 30 at the edges of the channels, each serving in pairs next to one another as a high-voltage electrode 41 and an earthed electrode 42.
- the electrodes 41 and 42 made of electrically conductive material are each surrounded by an electrically insulating barrier layer 43 which, in contrast to the filter material of the walls 30, has low porosity for reasons of high voltage resistance.
- FIG. 2 shows the distribution of the electric field strength, which is important for the formation of surface sliding discharges, for a voltage of 10 kV applied to the high-voltage electrodes with a square channel cross section of 2 2 mm 2 in the cross section of the arrangement according to FIG. 1.
- the field minima calculated in FIG Designated arrangement according to Figure 1. These minima are due to the quadrupole arrangement of the electrodes on the axes of symmetry of both the inlet and outlet channels. Areas of increased electric field strength 51, in which electric gas discharges will ignite preferentially, can be found in the vicinity of the channel walls of both the inlet and outlet channels.
- Figure 3 shows an electrode arrangement for the selective generation of gas discharges in the inlet channels in cross section.
- the main difference from Figure 1 is the diamond-shaped Order of the inlet channels 10 and the outlet channels 20, which results from a rotation of the structure according to FIG. 1 by 45 °.
- Another difference from the prior art is that on the inlet channels, which are now diamond-shaped, there are electrodes 40 in the vertical direction at opposite corners of the diamond, each of which is designed in pairs as a high-voltage electrode 41 and as a ground electrode 42. Again, a barrier layer 43 is provided for a porous filter material.
- FIG. 4 shows the advantageous distribution of the electric field of the arrangement according to FIG. 3, which preferably enables the ignition of gas discharges within the inlet channels.
- This calculated representation shows that, compared to FIG. 2, the inlet channels 10 have an increased electric field strength over almost the entire cross section, which is sufficient for the ignition of gas discharges, while in the outlet channels 20 only in the vicinity of the electrodes due to slightly increased electric fields ignition of gas discharges can be expected. Otherwise, field minima 50 according to FIG. 2 are again present.
- Preferred starting points for gas discharges in the inlet channels 10 are due to the particularly strong increase in the electric field strength there, first in the vicinity of the electrodes. However, since electrical charge carriers are stored there during operation of the gas discharge and thus the electric fields are reduced there, the preferred starting points of the gas discharges slide successively along the walls of the inlet channels 10 in the direction of the central region until the walls are so far covered with surface charges are that no more gas discharges can be ignited.
- the arrangement according to FIG. 3 not only results in an electrical field distribution that is advantageous for the efficient use of electrical energy, but also in a reduction in material and cost due to a reduced number of electrodes per filter volume and area and at the same time a reduced electrical capacity has a cost-reducing effect due to the simplified design of high-voltage power supplies for the electrical excitation of the plasma soot filter.
- What is essential for this is the arrangement of the electrodes on diagonally opposite edges of the square channel cross-section, with adjacent inlet channels necessarily having to be connected in the same polarity via their edges not provided with electrodes.
- FIG. 5 shows, as a detail from FIG. 3, the diamond-like cross section of an individual inlet duct with electrode 41, counterelectrode 42 and two axes 60 and 60 ⁇ , which define a double-beam symmetry. These elements are important for the functionality of the filter, the electrodes 41 and 42 being connected by the axis 60 as a line of symmetry.
- outlet channels are deformed in a complementary manner, so that the cross-section is completely covered again with inlet and outlet channels.
- any conversion of a square into an nx square with n> 2 is possible.
