Description
Verfahren und Vorrichtung zur Abgasreinigung in kraftfahrzeugen (Zusatz zum Patent (Patentanmeldung P 21 39 775.1)) Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Abgasreinigung in Kraftfahrzeugen. Process and device for exhaust gas purification in motor vehicles (addendum for patent (patent application P 21 39 775.1)) The invention relates to a method and a device for exhaust gas purification in motor vehicles.
Das Patent (Patentanmeldung P 21 39 775.1) hat ein Verfahren zur Abgasreinigung von Krnftfahrzeugen zum Gegenstand, bei dem das heisse Abgas einem elektrostatischen Filter zur Entfernung der Schwebeteilchen zugeführt und danach durch einen katalytischen Abgasreaktor geleitet wird.The patent (patent application P 21 39 775.1) has a method for exhaust gas cleaning from motor vehicles to the subject, in which the hot exhaust gas is an electrostatic Filter to remove the suspended particles and then fed through a catalytic Exhaust gas reactor is passed.
Sin weiterer Gegenstand dieses Patentes ist eine Vorrichtung zur Abgasreinigung in Kraftfahrzeugen nach diesem Verfahren, die ein hinter dem Auslassventil angeordnetes elektrostatisches Filter hat, dessen feldliniendurchsetztes Dielektrikum einen Teil des Abgaskanals bildet und den gesamten Querschnitt des Abgaskanals ausfüllt.Sin further the subject of this patent is a device for exhaust gas purification in motor vehicles using this method, which have a has an electrostatic filter, part of which has dielectric penetrated by field lines of the exhaust duct and fills the entire cross-section of the exhaust duct.
Das Entferllen von Schwebstoffen aus strömenden Gasen im elektrischen Feld eines Ring-, Zvlinder- oder Plattenkondensators ist hesonders daten erfolgreich, wenn die Schwebeteilchen hinreichend grosse elektrische ladungen tragen. Diese Ladungen sind nicht immer notwendigerweise durch die thermi--ctlen Vorgänge oder auftretende Eteibungsprozesse vorhanden.The removal of suspended solids from flowing gases in the electric Field of a ring, cylinder or plate capacitor is particularly data successful, when the suspended particles carry sufficiently large electrical charges. These charges are not always necessarily due to the thermal processes or occurring Registration processes exist.
Deshalb ist es zweckmässig, die Abgase, die aus dem Auslassventil ausgeströmt sind, vor ihrem Eintritt in den Ring-, Zylinder- oder Plattenkondensator durch das Haumladungsfeld einer Koronaentladung zu führen.It is therefore advisable to remove the exhaust gases from the exhaust valve have escaped before they enter the ring, cylinder or plate capacitor through the skin charge field of a corona discharge.
Aufgabe der vorliegenden Erfindung war es, dieses Verfahren wirksamer und wirtschaftlicher zu machen und eine Vorrichtung zu seiner Ausübung zu schaffen, die bei raumsparender Bauart eine hohe Leistungsfähigkeit besitzt.The object of the present invention was to make this process more effective and to make it more economical and to create a device for its exercise, which has a high efficiency with a space-saving design.
Die erste Aufgabe wird dadurch gelöst, dass die abzuscheidenden Schwebeteilchen im Raumladungsfeld einer Koronaentladung aufgeladen werden.The first object is achieved in that the suspended particles to be deposited be charged in the space charge field of a corona discharge.
Die zur Durchführung des Verfahrens geeignete Vorrichtung soll zur Erzeugung der Koronaentladung einen oder mehrere Spitzen oder einen oder mehrere Sprühdrähte haben. Dazu werden in das die Abgase fiihrende Auspuffsystem isolierende Durchführungen (ähnlich den Zündkerzendurchführungen) eingesetzt. Diese Durchführungen können mit Spitzen versehen sein, sie können aber auch zum Einhängen der Sprühdrähte ausgebildet werden.The device suitable for performing the method is intended to Generation of the corona discharge one or more peaks or one or more Have spray wires. For this purpose, isolating pipes are installed in the exhaust system carrying the exhaust gases Bushings (similar to the spark plug bushings) are used. These implementations can be provided with tips, but they can also be used to hang the spray wires be formed.
Besonders vorteilhaft ist es, wenn die Vorrichtung zur Erzeugung des Raumladungsfeldes gleichzeitig den Elektroabscheider darstellt. Die Sprühelektrode übernimmt dann sowohl die Aufgabe, mit ihrer Koronaentladung die notwendige Raumladung zu erzeugen, als auch das zur Abscheidung der aufgeladenen Schwebeteilchen notwendige elektrische Feld zu liefern.It when the device for generating the Space charge field simultaneously represents the electrostatic precipitator. The spray electrode then takes on both the task of providing the necessary space charge with its corona discharge to generate, as well as the necessary for the separation of the charged suspended particles supply electric field.
Besonders raumsparend wird diese Anlage, wenn das Auspuffrohr des Kraftfahrzeugs die Gegenelektrode darstellt.This system is particularly space-saving if the exhaust pipe of the Motor vehicle represents the counter electrode.
