Abstract

Nowadays the exhaust gases of internal combustion engines are often treated by catalytic processes or filtered. Neither process is ideal. In the process according to the present patent application the exhaust gases are made to flow through a vessel, in which they come in contact with a neutralising and filtering substance. The vessel gives rise to counter-pressure. In order to compensate for the said counter-pressure, a turbo compressor, which functions so that the exhaust gases first flow through the turbine and then through the compressor, is incorporated into the exhaust pipe system downstream of the engine. For the present patent application an axial flow turbo compressor is shown, but in practice it is possible to use a radial flow turbo compressor. When controlling exhaust emissions by this method turbocharging must be dispensed with or a double system fitted. A portion of the exhaust gas energy is then used to supercharge the engine, the other portion for the exhaust emission control.

Description

Stand der TechnikState of the art

In den Abgasen von Kraftmaschinen, die mit fossilen Brennstoffen betrieben werden, sind umweltschädliche Substanzen - SO2, NO und Ruß - enthalten.The exhaust fumes of motor vehicles that run on fossil fuels contain environmentally harmful substances - SO 2 , NO and soot.

Der Ruß kann in Elektrofiltern, durch katalytisches Verfahren und auch durch Verbrennen von der Druck­ wellenmaschine (Offenlegungsschrift EP 00 72 059) be­ seitigt werden.The soot can be found in electrostatic filters, through catalytic Process and also by burning the pressure wave machine (laid-open specification EP 00 72 059) be be sided.

SO2 und NO, die in Verbindung mit Wasser Säure bilden, können nur durch Neutralisation unschädlich gemacht werden. Die Neutralisation findet dadurch statt, daß das Abgas durch mehrere Schichten von neutralisieren­ dem Material, z. B. Kalcium Pellets strömt. Dieses Ver­ fahren ist in mittleren und großen Feuerungsanlagen in Gebrauch.SO 2 and NO, which form acid in combination with water, can only be neutralized by neutralization. The neutralization takes place in that the exhaust gas through several layers of neutralize the material, e.g. B. Calcium pellets are flowing. This method is used in medium and large combustion plants.

Wenn das Abgas durch die Neutralisationsanlage fließt, entsteht Druckwiderstand. Versucht man, eine solche Neutralisationseinheit direkt mit der Verbrennungsma­ schine zu koppeln, sinkt deren Wirkungsgrad erheblich.If the exhaust gas flows through the neutralization system, pressure resistance arises. If you try one Neutralization unit directly with the combustion measure coupling the machine reduces its efficiency considerably.

Dieses Problem wird durch die Erfindung dadurch gelöst, daß man im Abgasrohr einen Turbokompressor baut, der die Abgase durch die Neutralisationseinheit treibt. Durch dieses Verfahren werden die aus dem Motor kommen­ den Abgase beschleunigt. Dadurch wird auch der Wirkungs­ grad des Motors verbessert.This problem is solved by the invention in that that one builds a turbo compressor in the exhaust pipe drives the exhaust gases through the neutralization unit. This will get them out of the engine accelerates the exhaust gases. This also makes the effect degree of engine improved.

Wenn die Abgase durch den Neutralisationsbehälter strö­ men, sinken ihre Geschwindigkeit und ihre Turbulenz. Der Behälter wirkt daher gleichzeitig auch als Schall­ dämpfer.When the exhaust gases flow through the neutralization tank their speed and turbulence decrease. The container therefore also acts as sound damper.

Der Ruß setzt sich auf der Oberfläche des neutralisie­ renden Materials ab. Dadurch fungiert der Neutralisa­ tionsbehälter auch als Rußfilter. Durch den Neutrali­ sationsprozeß bildet sich ständig eine neue reine Oberfläche.The soot settles on the surface of the neutralisie materials. This is how the Neutralisa works tion container also as a soot filter. Through the neutral process is constantly developing a new pure one Surface.

Der Inhalt des Behälters muß bei Bedarf ausgetauscht werden. Das Material ist nicht teuer.The contents of the container must be replaced if necessary will. The material is not expensive.

Fig. 1 zeigt die thermodynamischen Verhältnisse des Abgasturbokompressors. Fig. 1 shows the thermodynamic conditions of the exhaust gas turbo compressor.

In Punkt 1. kommen die Abgase vom Motor in die Turbine. Sie entspannen sich durch die Turbine bis Punkt 2. Zwischen Punkt 2. und Punkt 3. ist Zwischenkühlung vor­ gesehen. Nach dem Kompressor, Punkt 4., fließen die Abgase zu dem Reinigungsbehälter.In point 1, the exhaust gases come from the engine into the turbine. You relax through the turbine up to point 2. There is intermediate cooling between points 2 and 3 seen. After the compressor, point 4., the flow Exhaust gases to the cleaning tank.

  • b) Kompressor undb) compressor and
  • c) Reinigungsbehälter.c) cleaning container.

Ein Axial-Typ-Turbokompressor wäre für diesen Zweck am besten geeignet, weilAn axial-type turbocompressor would be best for this purpose best suited because

  • 1. der Durchmesser der Anlage klein bleibt und die durch die hohe Drehzahl verursachten Zentrifugal­ kräfte gering bleiben und1. the diameter of the system remains small and the centrifugal caused by the high speed forces remain low and
  • 2. die Gasströmungslinie gerade ist.2. the gas flow line is straight.

Es wäre auch möglich, diese Anlage mit zwei Kompresso­ ren zu konstruieren. Einen Kompressor als Teil der hier beschriebenen Abgasreinigungsvorrichtung, den anderen für Frischluft, d. h., zum Laden des Verbrennungsmotors. In diesem Falle wäre eine Turbine vom Radial-Typ zweck­ mäßiger. Eine solche Anlage wäre in der Herstellung sehr teuer.It would also be possible to use this system with two compressors to construct. A compressor as part of this described emission control device, the other for fresh air, d. that is, for charging the internal combustion engine. In this case, a radial type turbine would be useful more moderate. Such a system would be in production very expensive.

Die Welle zwischen Turbine und Kompressor wird zweck­ mäßigerweise druckluftgeschmiert. Der Kompressor muß aus wärmebeständigem Material hergestellt werden.The shaft between the turbine and compressor is used moderately compressed air lubricated. The compressor must be made of heat-resistant material.

Fig. 3 und 3a zeigen den Axial-Typ-Turbokompressor im Prinzip. Die Turbine und der Kompressor könnten mehrstufig sein. FIGS. 3 and 3a show the axial type turbo compressor in principle. The turbine and the compressor could be multi-stage.

Der Reinigungsbehälter ist so geformt, daß die Abgase vorn eintreten und gezwungen werden, durch den Behäl­ ter zu strömen. The cleaning tank is shaped so that the exhaust gases Enter the front and be forced through the container to stream.  

Der Reinigungsbehälter ist mit Kalciumsplittern oder mit besonders für diesen Zweck hergestellten Pellets gefüllt.The cleaning container is with calcium chips or with specially made for this purpose Pellets filled.

Der Mantel des Behälters ist entweder mit Wasserküh­ lung oder mit Kühlungslamellen ausgerüstet.The jacket of the container is either with water cooling tion or equipped with cooling fins.

Vor dem Reinigungsbehälter sind ein Druckmesseran­ schluß, ein Unterdruckventil und ein Überdruckventil montiert. There is a pressure gauge in front of the cleaning tank circuit, a vacuum valve and a pressure relief valve assembled.
