Motor vehicle exhaust purifier has cylindrical openable container with rolled up length of absorbent coated thin metal sheet

Description

  

  
 



   Die Erfindung betrifft einen Gasentgiftungsapparat, insbesondere für Kraftfahrzeuge, mit einem einen Filter umschliessenden Behälter mit Anschlussrohr und Deckel.



   Es stellte sich das Problem, den Abgasen von Verbrennungsmotoren, insbesondere von Kraftfahrzeugmotoren, die schädlichen Stoffe, wie Kohlenmonoxyd, Schwefel, Blei usw.



  zu entziehen mit Hilfe einer einfachen, leicht anzubringenden und zu betätigenden Apparatur von möglichst gedrängter, unauffälliger Bauweise.



   Der erfindungsgemässe Gasentgiftungsapparat stellt eine kostengünstige Lösung dieses Problems dar. Dieser ist dadurch gekennzeichnet, dass der Filter ein spiralförmig gerolltes Feinblech aufweist, das beidseitig mit Adsorptionsstoffen beschichtet ist, und dass der Behälter einen kreisähnlichen Querschnitt besitzt, Mittel zur lösbaren Befestigung aufweist und der Deckel mit Schnellverschlüssen gehalten und mit einer Auspuffpfeife versehen ist.



   In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Es zeigen:
Fig. 1 einen teilweisen Querschnitt durch den halbaufgerollten Filtereinsatz;
Fig. 2 einen Grundriss des Filterbehälters mit Anschlussrohr und Deckel mit Auspuffpfeife in verkleinertem Massstab.



   Der dargestellte Abgasentgiftungsapparat ist insbesondere für Kraftfahrzeuge vorgesehen. Er weist einen Blechbehälter 1 mit einem kreisähnlichen Querschnitt auf. Dieser kann rund oder oval sein. Zur Befestigung an der Karosserie ist ein Aufhängelappen 2 angeschweisst.



   Auf der Gaseintrittseite ist der Behälter 1 mit einem Anschlussrohr 3 versehen, an welchem eine Rohrschelle 4 angebracht ist (Fig. 2). Diese dient zur Verbindung mit dem Rohrstutzen 5 des Schalldämpfers 6.



   Auf der   Gasaustrittseite    weist der Behälter 1 einen Dekkel 7 mit einer Auspuffpfeife 8 auf. Der Deckel 7 ist mittels Schnellverschlüssen 9 am Behälter 1 festgehalten. Als solche sind Haken-Hebel-Verschlüsse vorgesehen.



   Der Behälter 1 umschliesst einen Filter 10 (Fig. 1). Dieser Einsatzfilter weist ein spiralförmig gerolltes Feinblech von 0,04 bis 0,07 mm Dicke auf, das beidseitig mit Adsorptionsstoffen: Kieselgur, Quarz und Aktivkohlenschrot beschichtet ist. Die Korngrösse beträgt 3 bis 6 mm.   DieseAd-    sorptionsstoffe sind durch einen handelsüblichen, hitzebeständigen Leim am Feinblech festgehalten.



   Dem spiralförmig gerollten Filter 10 kann in der Strömungsrichtung ein Stahlwattefilter 11 vorgelagert sein, der als Russfänger dient, insbesondere für Diesel- und Petrolmotoren.



   Der Behälter 1 ist den Platzverhältnissen quer zum Schalldämpfer 6 vorgesehen und kann nach unbedeutenden Änderungen am Fahrzeug montiert werden.



   Weisen Fahrzeuge mehrere Auspuffanlagen auf, so können diese von den Filtern 10, 11 zusammengeleitet werden.



   Nach ca. 3000 km Fahrt mit Benzin müssen die Filter 10, 11 ausgewechselt werden, wenn eine optimale Wirksamkeit des Gasentgiftungsapparates erzielt werden soll. Bei Verwendung von Dieselöl oder Petrol ist die Wirkung der Filter 10, 11 nach 2000 km Fahrt ungenügend. Dann muss der Deckel 7 samt Auspuffpfeife 8 zur Herausnahme der Filter 10, 11 aus dem Behälter 1 gelöst werden.



   Gemäss den Testversuchen beim TCS-Luzern kann ein wesentlicher Beitrag zum Umweltschutz mit dem beschriebenen Gasentgiftungsapparat geleistet werden. 



  
 



   The invention relates to a gas detoxification apparatus, in particular for motor vehicles, with a container enclosing a filter with a connection pipe and cover.



   The problem arose of the exhaust gases from internal combustion engines, in particular from motor vehicle engines, the harmful substances such as carbon monoxide, sulfur, lead, etc.



  to be withdrawn with the help of a simple, easy-to-install and operate device of compact, inconspicuous design.



   The gas detoxification apparatus according to the invention represents a cost-effective solution to this problem. This is characterized in that the filter has a spiral-shaped rolled thin sheet that is coated on both sides with adsorbents, and that the container has a circular cross-section, has means for detachable fastening and the lid with Quick release fasteners and is provided with an exhaust pipe.



   An exemplary embodiment of the subject matter of the invention is shown in the drawing. Show it:
Fig. 1 is a partial cross-section through the half-rolled filter insert;
2 shows a plan view of the filter container with connection pipe and cover with exhaust pipe on a reduced scale.



   The exhaust gas detoxification apparatus shown is intended in particular for motor vehicles. It has a sheet metal container 1 with a circular cross-section. This can be round or oval. A hanging tab 2 is welded on for attachment to the body.



   On the gas inlet side, the container 1 is provided with a connection pipe 3 to which a pipe clamp 4 is attached (FIG. 2). This serves for the connection with the pipe socket 5 of the silencer 6.



   On the gas outlet side, the container 1 has a lid 7 with an exhaust pipe 8. The lid 7 is held on the container 1 by means of quick-release fasteners 9. Hook-and-lever closures are provided as such.



   The container 1 encloses a filter 10 (FIG. 1). This insert filter has a spiral-shaped rolled thin sheet of 0.04 to 0.07 mm thick, which is coated on both sides with adsorbents: kieselguhr, quartz and activated carbon shot. The grain size is 3 to 6 mm. These adsorbents are attached to the thin sheet with a commercially available, heat-resistant glue.



   A steel wadding filter 11, which serves as a soot trap, in particular for diesel and petrol engines, can be upstream of the spiral-shaped rolled filter 10 in the direction of flow.



   The container 1 is provided transversely to the muffler 6 and can be mounted on the vehicle after minor changes.



   If vehicles have several exhaust systems, these can be brought together by the filters 10, 11.



   After driving about 3000 km on petrol, the filters 10, 11 must be replaced if the gas detoxification apparatus is to be optimally effective. When using diesel oil or petrol, the effect of the filters 10, 11 is insufficient after a journey of 2000 km. Then the cover 7 together with the exhaust pipe 8 must be loosened in order to remove the filters 10, 11 from the container 1.



   According to the tests at the TCS-Lucerne, a significant contribution to environmental protection can be made with the described gas detoxification apparatus.
