Definitions

  • the present invention relates to a particulate retention and cleaning system which is used in the retention and storage of particulate matters in the exhaust gases that are discharged as waste in all devices such as vehicles, and in the retention of all particulates contained in exhaust gases occurring as a result of combustion and cleaning of them before being discharged into the environment.
  • the purpose of the catalytic converter or emission control system is to make harmful pollutants discharged from the exhaust harmless. Due to their poor mixture compared to gasoline -powered vehicles, diesel engine vehicles produce less carbon monoxide (CO), hydrocarbon (HC) and carbon dioxide (C02) exhaust emissions, while producing more particulate (PM) and nitrous oxide (NOX) emissions. Diesel Particulate Filters (DPF) are used in diesel engines to retain particulates present in the exhaust gas.
  • the filter member is usually formed by coating a porous ceramic or SiC based material on a stainless steel carrier with a plurality of holes on it. The particulates are retained on the surface while exhaust gases pass through the ceramic surface filter. It has been observed in studies conducted so far that particulate filters work with an efficiency of around 80%. The meaning of this is that 80% of the particulates visible in the exhaust gas can be retained in the filter.
  • the accumulation of particulates retained in the exhaust filter reduces the efficiency of the filter. For this reason, it is required to clean the particulates accumulated in the filter regularly.
  • the toxic gases are retained as described above, while the particulate matter, PM, which is among the combustion byproducts fill up the pores in the ceramic structure, and the material accumulated over time narrows the passage volume and causes a decrease in power by increasing the engine back pressure.
  • the regeneration process that is activated in this case that is, increasing the filter temperature bums these particulate matters that are accumulated, and the ashes, which are the byproducts of burning, are discharged to the air we breathe as ashes this time, not as particulate matter.
  • some particulates comprising components such as sulfur, potassium, etc. generated as a result of combustion cannot be burned by the regeneration process.
  • These particulates which comprise approximately 5% by mass of the particulates in the exhaust gases, accumulate in the filter pores and shorten the filter life very quickly.
  • Korean patent document no KR100670939 an application in the state of the art, discloses process of spraying compressed air to separate the burnt particulates from the filter in the diesel particulate filter. There is an air nozzle in the said application, and compressed air transferred onto the filter through the said air nozzle. In the aforementioned application, since the particulates removed from the filter do not will remain around the filter, this is not a definitive solution.
  • European patent document no EP0682174 an application known in the state of the art, discloses a diesel particulate filter comprising electric resistance thereon in order to burn the particulates accumulated thereon.
  • ashes which are byproducts of burning are formed after the burning process and these ash products are discharged into the air we breathe.
  • the objective of the present invention is to provide a particulate retention system which is used in all applicable devices such as vehicles to retain the particulate matters in the exhaust gases discharged as waste without any burning process and to store them without being discharged to the outside and being released to the environment in any way.
  • the objective of the present invention is to provide a particulate retention system which enables to capture and store not only certain particulates, but all particulates with different components in the exhaust gas.
  • the objective of the present invention is to provide a particulate retention system which enables to clean particulate matters by means of a mechanical action without performing a chemical process and to be discharged as waste without being released into the nature (without harming the environment).
