Definitions

  • the present invention relates to a counterflow device for recuperation in particulate filter systems. Furthermore, the invention relates to a particulate filter system comprising the countercurrent device according to the invention.
  • Particulate filter systems or particulate filter arrangements serve for filtering exhaust gases of an internal combustion engine, for example a diesel engine, and have an inlet and an outlet with at least one particle filter arranged in the flow path.
  • the particulate filter has the task of removing the soot particles present in the exhaust gases. Especially at low temperatures, it tends to clog up quickly. Therefore, it is endeavored to operate the particle filter at the highest possible temperatures to a regeneration of the soot particles stored in the filter
  • Ignition temperature of the soot particles is as high as possible, even if the diesel engine is operated with only low load proportions. If the diesel engine is operated only at low load, the exhaust gas temperature remains correspondingly low in this operating state, so that the filter can not regenerate and the soot particles remain in the filter.
  • the heavy loading of the filter and the gas-carrying ducts with soot leads to malfunction of the system and the engine (for example, loss of power, increased fuel consumption) and also increases the risk of fire. After some time, the motor vehicle is no longer ready for use and the filter must be replaced or cleaned consuming.
  • Incorporate combustion process in the supply air for combustion for example, to preheat the intake air of an engine.
  • the passive system described is a particle filter arrangement in which the ignition temperature required for the regeneration is reduced by means of heat exchange.
  • use is made of a temperature gradient between the exhaust gas streams, for which purpose three sections are provided in the device described therein, through which the exhaust gases flow. Initially, the exhaust gases are directed essentially towards the outlet, later towards the inlet and thus into Returned the opposite direction, and finally led back towards the outlet.
  • the exhaust system therefore takes place essentially in the manner of a degenerate "Z".
  • the diesel particulate filter is arranged in one of the sections and is flowed around.
  • a distribution and deflection element is provided in EP 1 801 372 A1, which leads a first exhaust gas flow coming from the inlet to the first section of the line, and deflects a second exhaust gas flow arriving from the second section of the line to the third section of the line. It is preferred to realize a star-shaped deflection, in which the various exhaust gas streams cross over without them mixing.
  • Exhaust gas routing causes the distribution and diverting element to heat up and deliver heat to the colder exhaust gas.
  • the inventive countercurrent device for recuperation in diesel particulate filters comprises a housing with an inner jacket and a front and a rear end face.
  • the jacket can preferably be formed by a pipe or a piece of pipe (eg support tube).

Furthermore, the device has an outlet opening for the cold exhaust gas and at least one outlet opening for the warm exhaust gas at the housing.
  • the countercurrent chambers are arranged axially around the housing. This results in several countercurrent chambers, which have contact surfaces for the heat exchange of the exhaust gas streams passing one another, whereby a maximum heat exchange can take place in a space that is less available.
