Description
Vorrichtung zum reduzieren von Feinstaub/RußpartikelDevice for reducing fine dust / soot particles
Ruß tritt auch bei Verbrennungsvorgängen als unerwünschtes Produkt auf und enthält auch ölige Produkte aus unvollständiger Verbrennung. Solcher Ruß hat im Tierversuch das Potential, Krebs auszulösen. Bei der unvollständigen Verbrennung entstehen polycyclische aromatische Kohlenwasserstoffe die die Krebsgefährdung bedingen. In alten Heizungsanlagen setzte sich Ruß beim Abkühlen als Produkt der unvollständigen Verbrennung ab und verursachte das Versotten von Schornsteinen. Die Schadwirkung von Ruß geriet wiederholt in den Blickpunkt der Medien; ein Beispiel dafür ist die Diskussion um den Dieselruß in Fahrzeug AbgasenCarbon black also appears as an undesirable product during combustion processes and also contains oily products from incomplete combustion. Such soot has the potential to cause cancer in animal studies. Incomplete combustion produces polycyclic aromatic hydrocarbons that cause cancer. In old heating systems, soot deposited on cooling as a product of incomplete combustion and caused the mucking of chimneys. The harmful effects of soot have repeatedly been the focus of the media; an example of this is the discussion about the diesel soot in vehicle exhaust gases
Trotz moderner Technik ist der Ruß aus Dieselmotoren noch nicht wie gewünscht reduziert. Dafür legt die
Moderne Dieselfahrzeuge erzeugen kaum Schadstoffe und stellen für die Gesundheit auch praktisch keine Gefahr dar. So haben es die Hersteller immer wieder betont – und so sollte es laut
Neu zugelassene Autos mit Dieselmotor dürfen nicht mehr als 80 Milligramm Stickoxide pro Kilometer ausstoßen. Um das zu erreichen, sind alle neu zugelassenen Dieselfahrzeuge mit einem Katalysator bestückt. Bei größeren Motoren nutzen diese Katalysatoren eine Harnstofflösung, die Stickstoffoxide bindet (Selective Catalytic Reduction, SCR). Dieses System arbeitet sehr effektiv, hat aber einen Nachteil: Die Harnstofflösung muss regelmäßig nachgefüllt werden.Newly registered cars with a diesel engine may not emit more than 80 milligrams of nitrogen oxides per kilometer. To achieve this, all newly approved diesel vehicles are equipped with a catalytic converter. For larger engines, these catalysts use a urea solution that binds nitrogen oxides (Selective Catalytic Reduction, SCR). This system works very effectively, but has one drawback: The urea solution needs to be topped up regularly.
Mit diesen Katalysatoren wird das Abgas teilweise von Schadstoffen befreit aber ein Rest bleibt.With these catalysts, the exhaust gas is partially released from pollutants but a remainder remains.
Der Stickoxidausstoß bei Dieselfahrzeugen wird derzeit nach einem Verfahren namens Neuer Europäischer Fahrzyklus (NEFZ) ermittelt. Der Test steht aber in der Kritik, weil er kaum etwas mit der realen Fahrpraxis zu tun hat. Bei einer Messung unter praxisnahen Bedingungen fielen kürzlich 22 von 32 untersuchten Fahrzeugen durch – obwohl alle gemäß NEFZ die Zulassung erhalten hatten. Ein ernstes Problem für die Luft in Deutschland, wo fast jeder zweite Neuwagen ein Diesel ist.Nitrogen oxide emissions from diesel vehicles are currently being determined using a process called the New European Driving Cycle (NEDC). The test is in the criticism, because he has little to do with the real driving experience. In a test under practical conditions, 22 out of 32 vehicles were recently tested - even though all had been approved according to NEDC. A serious problem for the air in Germany, where almost every second new car is a diesel.
Kontinuierlich Regenerierende Partikelfilter (CRPF) für Dieselmotoren Sind weit verbreitet. Sie bestehen aus einem Partikelfilter zur Abscheidung der Rußpartikel (PM) und einem diesem vorgeschalteten Oxidationskatalysator. Das Roh Abgas überströmt zunächst den Oxidationskatalysator, wo das im Roh Abgas enthaltene NO (Stickstoffmonoxid) mit überschüssigem Sauerstoff zu NO2 (Stickstoffdioxid) oxidiert. Dieses NO2 dient im nachgeschalteten Partikelfilter als Oxidationsmittel zur Verbrennung der Dort angesammelten PM (”Regeneration”).Continuous Regenerative Particulate Filters (CRPF) for diesel engines are widely used. They consist of a particle filter for the separation of the soot particles (PM) and an oxidation catalyst upstream of this. The raw exhaust gas first flows over the oxidation catalyst, where the NO (nitrogen monoxide) contained in the raw exhaust gas is oxidized with excess oxygen to form NO 2 (nitrogen dioxide). This NO 2 is used in the downstream particulate filter as the oxidant for combustion of PM accumulated there ("regeneration").

Die am Markt befindlichen Katalysatoren schaffen es nicht Ruß Partikel vollständig aus Abgasen zu entfernen.The catalysts on the market do not manage to completely remove soot particles from exhaust gases.
Aufgabe der Erfindung ist es ein Abgasreinigendes Filtersystem zu schaffen zur Reduzierung fester Partikel in Abgasen, insbesondere von Dieselmotoren. Sie betrifft ein Verfahren und eine Vorrichtung nach den Oberbegriffen der entsprechenden Unabhängigen Patentansprüche. Ein Verfahren und Vorrichtung zur Verringerung der Ruß Partikel von kontinuierlich regenerierenden Partikelfiltern.The object of the invention is to provide an exhaust gas cleaning filter system for reducing solid particles in exhaust gases, in particular of diesel engines. It relates to a method and a device according to the preambles of the corresponding independent claims. A method and apparatus for reducing soot particles from continuously regenerating particulate filters.
Die Aufgabe der Erfindung wurde dadurch gelöst das ein durch den Abgasstrom angetriebenes Schaufelrad das Abgas so umleitet das die festen Bestandteile durch Fliehgraft radial nach außen schleudert werden und sich an gewünschter stelle ansetzen. Mit Hilfe der erzeugten Rotations Energie kann die mechanische Strömungsenergie in Elektrische Energie umgewandelt werden. Diese Energie kann genutzt werden um ein eklektisches Feld zu erzeugen das die Fest Stoffe Positiv auflädt und diese sich an entsprechender negativ geladenen Stelle absetzen.The object of the invention has been achieved by a driven by the exhaust flow paddle wheel bypasses the exhaust gas so that the solid components are thrown by centrifugal force radially outward and start at the desired location. Using the generated rotational energy, the mechanical flow energy can be converted into electrical energy. This energy can be used to create an eclectic field that positively charges the solid matter and deposits it at the corresponding negatively charged site.
