Definitions

  • the invention relates to a soot filter for cleaning the exhaust gas flow of an internal combustion engine according to the preamble of claim 1.
  • soot filters are known from DE-A-30 07 642. A possibility for cleaning such filters by burning off the soot accumulated on the filter candles is not specified there.
  • the present invention is concerned with the last-mentioned type of cleaning of the filter cartridges by means of electrical energy and has set itself the task of improving the cleaning by saving energy with little design effort.
  • the clear distance of all adjacent filter cartridges from one another is 2 to 4% of the mean outer diameter of the filter cartridges and in each cavity formed from at least three filter cartridges an elongated interruption of the exhaust gas flow generated by the internal combustion engine being at a standstill or by separating filter cartridge groups switchable electric radiator is arranged.
  • the burning off of the deposited soot is advantageously supported in that a device for supplying a small amount of air into the inflow chamber is provided for burning off the soot when the exhaust gas flow is interrupted, which is 2 to 6%, preferably 4%, of the full-load exhaust gas amount.
  • the structure is simple in that the device consists of a blower.
  • the burning off of the soot also at the locations distant from the radiators is advantageously supported in that the ceramic yarn is coated with a catalytic material which promotes the oxidation of the deposited soot, for example copper oxide or iron oxide.
  • a soot filter 10 has a cylindrical filter housing 11 with a housing jacket 12, with a base 13 and with a cover 14.
  • a feed connector 15 for the exhaust gases of the internal combustion engine opens into the base 13.
  • a discharge pipe 16 opens out, through which the cleaned exhaust gases are released.
  • a transverse wall 20 divides the interior of the filter housing 11 into an inflow chamber 21 and a clean gas collection chamber 22.
  • Filter candles 30 fixed on the transverse wall 20 consist of heat-resistant, wound in a coil-like manner into hollow cylinders Ceramic yarn with a roughened surface.
  • the filter candles 30 are combined in groups so that three (FIG. 2) or four (FIG. 3) or five (FIG. 4) come to rest with their axes on a circular ring 31, 32, 33. Otherwise, the filter candles 30 are each arranged parallel to one another and are closed by end disks 34 on the one end with which they protrude into the inflow chamber 21.
  • the filter candles 30 On the opposite end, which is fixed on the transverse wall 20, the filter candles 30 have clean gas outflow openings 35 which open into the clean gas collection chamber 22.
  • the filter cartridges 30 are arranged in such a way that the clear distance A of all adjacent filter cartridges from one another is 3% of the average filter cartridge outer diameter D.
  • an elongate electric heating element 37 is arranged in each cavity 36 formed from three filter candles 30.
  • the radiators 37 are fixed to a grating 39 and attached to the transverse wall 20 at the end facing the discharge nozzle 16.
  • An electrical line 40 leads to a control unit, not shown.
  • the cavity 42 is formed by four filter candles and in the exemplary embodiment in FIG. 4 the cavity 43 is formed by five filter candles.
  • the spacing of the adjacent filter cartridges 30 from one another is 3% of the average filter cartridge outer diameter.
  • An elongated electric heating element 37 is also arranged in the cavities 42, 43.
  • a device 50 consisting of a fan is provided, which has a communication with the inflow chamber 21 via an inflow channel 51.
  • a shut-off valve 52 is arranged in the inflow channel 51 in order to be able to open or close the inflow channel.
  • the blower is designed such that it can supply an amount of air which is 4% of the full-load exhaust gas amount of the internal combustion engine when the shut-off valve 52 is open.
  • the ceramic yarn is coated with copper oxide to promote the oxidation of the deposited soot.
  • the exhaust gases flow through the supply connection 15 into the inflow chamber 21 of the soot filter 10, cross the filter candles radially from the outside inwards and leave the soot filter 10 after flowing through the clean gas outflow openings 35 and the clean gas collection chamber 22 through the discharge connection 16.
  • the butterfly valve 52 is closed.
  • soot particles settle on their surface. If the deposited soot layer has reached a predetermined thickness and the flow resistance has thereby increased to a predetermined value, current is supplied to the radiators 37 when the internal combustion engine is stopped by a suitable control device through the electrical line 40.
  • the radiators 37 heat up and, via the air surrounding them, the soot filter layer on the filter candles 30, which have already been heated up by the previous operation of the internal combustion engine. Finally, the soot layer begins to burn off from the locations closest to the radiators 37.
  • the blower device 50 is switched on with the radiators 37, which is 4% of the full-load exhaust gas quantity of the internal combustion engine when it is open Butterfly valve 52 is conveyed as air through the inflow chamber 21 through the filter candles 30.
  • shutting down the internal combustion engine it can also be provided to separate groups of filter candles by means of appropriately arranged butterfly valves.
  • two of the soot filters 10 shown in FIGS. 1 and 2 can be provided, one of which is separated from the exhaust gas flow of the internal combustion engine via a valve device in order to burn off the soot that has been deposited.
