Definitions

  • Particulate filter of the aforementioned type are known from WO 02/102493 A2 known.
  • the burning off of the soot particles with heating coils is also known.
  • These burn-off systems all have the disadvantage that the heat impinges on the particles, so as to cause the soot particles to burn.
  • These systems require a lot of energy because the exhaust gas flow, a significant proportion of hot air, which is urgently needed to burn off the soot particles, enters the environment without reaction. Forcibly, the energy consumption is increased unnecessarily.
  • a continuous particle cleaning is provided in this new particulate filter, but it can be the heating element and or heating elements, without the housing to be opened, replaced, wherein the heating elements are designed so that they are partially used as a particulate filter. Furthermore, it is advantageous that the structural requirements in the arrangement and flexibility throughout the design and shape of the Soot particle filters are given. Another advantage of the innovation is that the particles act on the filter element are burned directly from the inside out. This has the consequence that compared to non-contact heat sources a significant amount of energy is saved.
  • Another recommended feature is to provide the housing with a thermal jacket from the inside to the outside, or to encase it from the outside with a thermal trouser. This in turn has the advantage of saving energy, since the exhaust heat is stored over a longer period of time and the housing can not be cooled by the wind. In addition, the risk of fire is reduced by heating the housing to the environment.
  • stabilization heating elements 8 For burning off and regenerating the soot particles, depending on the nature and structuring of the monolith and / or particulate filter element, appropriately fitted and shaped stabilization heating elements 8 are screwed from the outside onto the threaded openings 6, 7 located on the filter housing.
  • Fig.2 shows a heating element 8 in corkscrew mold 16, Figure 3 a heating element 8 with heating rods 17.
  • the stabilization heating elements can be inserted by means of a quick release.
