Definitions

  • the disclosure relates to a device for cooling an exhaust gas stream emerging from a soot particle filter.
  • soot particle discharge is restricted by using soot particle filters, as a rule with “wall-flow filters,” in which the engine exhaust gas passes through a porous filter wall of a ceramic or metallic material.
  • soot particle filters as a rule with “wall-flow filters,” in which the engine exhaust gas passes through a porous filter wall of a ceramic or metallic material.
  • the soot particles contained in the engine exhaust gas become deposited both on the surface and also inside the filter wall, such that the exhaust gas back-pressure increases as the degree of clogging of the filter wall increases.
  • the deposited soot particles are therefore burned at regular intervals, for which purpose the temperature of the engine exhaust gas is increased from time to time to temperatures of over 500° C., for example using an oxidation catalytic converter connected upstream of the soot particle filter.
  • the temperature of the engine exhaust gas is increased from time to time to temperatures of over 500° C., for example using an oxidation catalytic converter connected upstream of the soot particle filter.
  • correspondingly high exhaust gas temperatures may occur at the tail pipe of the exhaust gas system (exhaust), which may lead to the formation of undesirable nitrogen oxides.
  • DE 10 2008 051 958 A1 discloses a device for reducing the temperature of an exhaust gas stream emerging from a diesel particle filter, wherein cooler ambient air is admixed with the waste gas stream by means of an air pump during regeneration of the diesel particle filter. Because the air pump is electrically controlled, the known device is of comparatively complex construction.
  • a device for cooling an exhaust gas stream emerging from a soot particle filter comprises an outlet connector provided on the soot particle filter for conveying out the exhaust gas stream, the outlet connector comprising a mouth region tapering in the direction of the exhaust gas stream, which region projects into an open end of an adjacent exhaust gas pipe in such a way that a reduced pressure relative to the surrounding environment may be produced in a suction region between the outlet connector and the exhaust gas pipe on passage of the exhaust gas stream. More precisely, the reduced pressure is produced according to the Venturi principle, wherein the mouth region of the outlet connector extends in the manner of a nozzle into the open end of the exhaust gas pipe.
  • the ambient air drawn into the exhaust gas pipe due to the reduced pressure leads in the process, depending on the temperature thereof, to corresponding cooling of the exhaust gas stream.
  • the device is distinguished not only by a particularly simple, but simultaneously also by an extremely compact structure, it is possible to accommodate said device together with the soot particle filter inside an engine compartment of a motor vehicle operated by a diesel engine, in particular, of an agricultural utility vehicle.
  • Cooling of the diesel engine is conventionally achieved by a high temperature heat exchanger arranged in the engine compartment of the motor vehicle, which heat exchanger is a component of a liquid cooling circuit connected with the diesel engine, the high temperature heat exchanger being exposed to cooling air by means of a fan unit, which cooling air is drawn from the surrounding environment by way of a radiator grille and downstream filter inserts. Since the air conveyed in this way into the engine compartment is largely free of contaminants, undesired clogging of the suction region formed between the outlet connector and the exhaust gas pipe is largely avoided. In addition, the compression of the air located in the engine compartment, brought about on the part of the fan unit, leads to an increased volumetric flow rate in the suction region and thus to more efficient cooling of the exhaust gas stream.
  • the outlet connector is connected detachably to a fastening flange of a filter housing surrounded by the soot particle filter.
  • the fastening flange is a fixed component of the filter housing and, as such, is welded or otherwise firmly connected thereto.
  • the outlet connector may comprise a fastening portion, which may be plugged onto the fastening flange and which may be brought into airtight engagement with the fastening flange.
  • the detachable connection between the outlet connector and the fastening flange of the filter housing may be produced in particular by means of a removable spring clip.
  • the spring clip here consists of a stainless steel or otherwise appropriately surface-treated steel alloy.
  • the spring clip grips around the outlet connector in the region of the fastening portion in such a way that, by reducing the circumference of the spring clip by means of a clamping screw or the like, a clamp connection may be produced between the outlet connector and the fastening flange of the filter housing.
  • the outlet connector may comprise a plurality of fastening tabs extending transversely of the spring clip in the region of the fastening portion.
  • the outlet connector may also be a fixed component of the filter housing surrounded by the soot particle filter. The outlet connector is then welded or otherwise firmly connected to the filter housing.
  • the suction region takes the form of an annular gap extending radially between the outlet connector and the exhaust gas pipe.
  • both the outlet connector and the exhaust gas pipe have a substantially circular cross section at least in the suction region.
  • exhaust gas stream cooling efficiency may be optimized if the ratio between an outer radius and an inner radius of the annular gap has a value in the range from 1.90 to 2.10.
  • the exhaust gas stream temperature may be reduced by more than 200° C. It should be noted, however, that the above details are given merely by way of example and may differ to a greater or lesser degree as a function of the particular operating conditions.
  • the mouth region of the outlet connector preferably extends throughout over its entire circumference at a distance from the open end of the exhaust gas pipe.
  • the mouth region of the outlet connector is self-supporting relative to the open end of the exhaust gas pipe. The distance is selected such that, in the event of vibrations occurring between the outlet connector and the exhaust gas pipe as a result of operation, the mouth region of the outlet connector may move inside the open end of the exhaust gas pipe without touching it. This ensures extensive mechanical decoupling of the two components.
  • the filter element prefferably taper in the direction of the outlet connector.
  • the filter element tapers only insofar as to rule out mutual contact between the outlet connector and the exhaust gas pipe in the event of vibrations occurring between them as a result of operation.
  • the suction region may be surrounded by a filter element, in particular by a perforated mesh.
  • the openings in the perforated mesh are dimensioned such that above all relatively coarse contaminants, which would lead rapidly to clogging or blocking of the suction region, are reliably retained.
  • the perforated mesh is made from an aluminium-coated steel alloy or the like.
  • the filter element may be arranged at the open end of the exhaust gas pipe and extend in the direction of the outlet connector. More precisely, the filter element forms an extension arranged on the exhaust gas pipe, which beyond the suction region surrounds the outlet connector over its entire circumference in the manner of a collar.
  • the filter element prefferably taper in the direction of the outlet connector.
  • the filter element here tapers only insofar as to rule out mutual contact between filter element and outlet connector in the event of vibrations occurring between the outlet connector and the exhaust gas pipe as a result of operation.
  • the exhaust gas pipe may be surrounded by a touch guard.
  • the touch guard takes the form in particular of a tubular cover, which is fitted along the outside of the exhaust gas pipe by means of a plurality of spacers.
  • the tubular cover may comprise a plurality of openings at least in the region of an exhaust, which allow circulation of the air present between the exhaust gas pipe and the tubular cover.
