Definitions

  • the present invention relates to an exhaust gas filtration device using a tube-type heater, and more particularly, to maximize the exhaust gas inflow area, to facilitate back pressure control, to minimize heat loss, and to react and regenerate by using a metal foam heater. It relates to an exhaust gas filtration device using a tube-type heater that can improve the performance.
  • a metal foam heater is disposed to form a hollow cylindrical shape, and generates heat of resistance when electricity is applied to heat the exhaust gas discharged through the exhaust pipe to generate heat;
  • connection terminal coupled to one end of the first and second metal foams and electrically connecting the first metal foam and the second metal foam to each other;
  • FIG. 2 is a partial perspective view of the exhaust gas filtration apparatus using the tube-type heater according to the first embodiment of the present invention, in which the external filter body is omitted.
  • connection terminal 130 coupled to one end of the first and second metal foams 110 and 120 and electrically connecting the first metal foam 110 and the second metal foam 120 to each other.
  • the first metal foam 110 and the second metal foam 120 may be formed in different sizes and shapes, but are preferably formed in the same size and shape so as to effectively heat the exhaust gas.
  • the isolation member 400 may be formed of a material such as, for example, stainless steel.
  • the exhaust gas passes through the internal filter body 300, for example, a diesel particulate filter (DPF) or a diesel oxidation catalyst (DOC), or a nitrogen oxide removal device.
  • a diesel particulate filter DPF
  • DOC diesel oxidation catalyst
  • NO x nitrogen oxides
  • CO carbon monoxide
  • HC hydrocarbons
  • PM particulate matter
