Definitions

  • the invention relates to a device for cleaning exhaust gases from internal combustion engines, in particular diesel soot filters, according to the preamble of patent claim 1.
  • the object of the invention is to prevent these disadvantages by constructive measures.
  • the hollow interior of the ceramic body is also closed at the rear by an insulator, preferably by a ceramic stopper, which preferably has a passage of 1-2 mm in diameter through which the internal electrode is subjected to high voltage is supplied.
  • the supply of the high voltage at the rear has the advantage that very small soot deposits are already present in this area and, moreover, the field strength at the bushing is so high due to the small diameter of the feed line that there is an immediate burning off of the deposits there Soot comes, which in turn prevents the formation of conductive soot bridges.
  • the discharge electrode can be carried by the ceramic body and have the same high-voltage potential as the inner electrode.
  • the tendency towards spark formation in the area of the discharge electrode due to the deposited soot is countered according to the invention in that the counter electrode opposite the discharge electrode has a ceramic coating with high electrical resistance.

This prevents the formation of conductive soot bridges in the inlet and outlet areas of the channels of the ceramic body.
  • a PTC thermistor is arranged between the inner electrode which is at high voltage and the inner cylinder surface of the ceramic body.
  • the PTC thermistor preferably increases its volume resistance from values below 10 megohm.cm 2 to at least 100 megohm.cm 2 , preferably 300 megohm.cm 2 , with a temperature increase from 100 ° C. to 500 ° C.
  • the resistance of the ceramic body decreases too much at higher temperatures, the high voltage at the inner electrode must be reduced, since only a limited power can be drawn from the vehicle electrical system from the power supply unit supplying the high voltage.
  • the discharge electrode or counter electrode which is electrically connected in parallel with the inner electrode, would cease to function.
  • the PTC thermistor compensates for the resistance of the ceramic body, which decreases at higher temperatures, so that the function of the discharge electrode or the counterelectrode is not impaired. If an inhomogeneous current distribution occurs in the ceramic body, local heating of the ceramic body also results, which can lead to thermal damage to the ceramic body. The local heating regulates the local power supply back via the increasing resistance of the PTC thermistor, which leads to a uniform distribution of the power supplied.

  • the tube 7 tapers on the outlet side to a connection end 12 which engages in a receiving opening 13 of a cylindrical ceramic holder 10 and is supplied with high voltage via a conductor 11 guided in the holder 10.

  • the exhaust gas loaded with diesel soot particles flowing in at the inlet side A flows into the annular channel 26 formed by the discharge electrode 8 and the counterelectrode 28 against the inlet openings of the channels 20 of the ceramic body 1.
  • the exhaust gas components are ionized in the annular channel 26 and penetrate into the channels 20 of the ceramic body 1. Because of the electrical field built up transversely to the channels 20, the soot particles contained in the exhaust gas and charged by the discharge electrode 8 are deposited on the wall surfaces of the channels 20 and electrochemically by a gas plasma formed from emitted electrons due to the high electrical field strength oxidized. Soot particles of the exhaust gas leaving the annular space 26 cannot reach the interior 22 of the ceramic body 1 and thus the inner electrode 5 due to the stopper 4.

  • the small diameter of the pipe 7 or the connection end 12 leads to the occurrence of high field strengths, by means of which the soot deposited there burns through sparking.
  • the inner electrode 5 and the outer electrode 6 do not extend over the entire length of the ceramic body 1, so that an almost field-free flow area is retained in the inlet and outlet area of the ceramic body 1. This precludes short-circuiting of the inner electrode 5 with the outer electrode 6 via any soot bridges occurring at the inlet or outlet openings of the channels.

Abstract

L'invention concerne un dispositif de purification des gaz d'échappement d'un moteur à combustion interne, en particulier un filtre à suie de diesel. Ledit dispositif comporte une électrode de décharge (8) une contre-électrode (28) opposée à celle-ci et servant à charger électriquement les composants des gaz d'échappement, un corps céramique (1) de section circulaire et des canaux (20) traversant ledit corps dans le sens d'écoulement, et une électrode interne (5) à haute tension. Cette électrode est placée sur la paroi de cylindre intérieure (21) du corps céramique (1) et crée un champ électrique perpendiculaire aux canaux (20) qui traversent ledit corps. Les particules de suie sont déposées et oxydées sur les parois des canaux (20), et une séparation sert à empêcher le passage d'un écoulement à travers l'espace (22) intérieur vide du corps céramique (1). Pour empêcher la formation de ponts de suie conducteurs entre les composants conducteurs à haute tension et la terre, la séparation de l'espace (22) intérieur vide du corps céramique (1) est un isolant électrique, de préférence un bouchon céramique (4), placé du côté de l'entrée du courant de gaz.
