Abstract

To increase the efficiency of exhaust gas scrubbers for internal combustion engines, an additive is added to the conventional water filling which is composed of a surfactant or surfactant hydrogen carbonate, as a result of which soot and other pollutants are considerably more effectively absorbed.

Description

Praktisch werden ca. 0,5 Val Säure gebunden. Der Farbumschlag von Blau nach Gelbgrün zeigt die Erschöpfung der Füllung an. In practice, about 0.5 eq of acid are bound. The color change from Blue to yellow-green indicates the exhaustion of the filling.

Claims (1)

Patentanspruch: Verfahren zur Reinigung der Abgase aus Verbrennungsmotoren mittels Abgaswäsche, d a -durch gekennzeichnet, daßeinAdditiv,bestehend aus folgenden Komponenten, eingesetzt wird: 1. alkalisches, nichtschäumendes Tensid 2. Natriumhydrogencarbonat 3. Bromthymolblau als Farbindikator Die Erfindung betrifft ein Verfahren zu verbesserter Reinigung der Abgase aus Verbrennungsmotoren, wobei den nachgeschalteten Abgaswäschern ein Additiv zugesetzt wird. Claim: Process for cleaning exhaust gases from internal combustion engines by means of exhaust gas scrubbing, d a -characterized in thatanadditive consisting of the following Components used: 1. alkaline, non-foaming surfactant 2. sodium hydrogen carbonate 3. Bromthymol blue as a color indicator The invention relates to a method for improved Purification of exhaust gases from internal combustion engines, with the downstream exhaust gas scrubbers an additive is added. Zur Reduzierung der Schadstoffe in den Abgasen von Verbrennungsmotoren gibt es für Benzinmotoren die Abgasrückführung und die katalytische Reinigung, für Dieselmotoren den Abgaswäscher. Beim Benzinmotor soll die Emission von nitrosen Gasen, Kohlenmonoxid und unverbranten Kohlenwasserstoffen reduziert werden, beim Dieselmotor der Ausstoß von Ruß und höheren Kohlenwasserstoffen. Abgaswäscher arbeiten im Gegensatz zu Katalysatoren und Rückführmethoden sofort beim Starten des Motors sowie bei allen Drehzahlen und in allen Lastbereichen. To reduce the pollutants in the exhaust gases from internal combustion engines there is exhaust gas recirculation and catalytic cleaning for gasoline engines, for Diesel engines the exhaust gas washer. In the case of gasoline engines, nitrous emissions are said to be Gases, carbon monoxide and non-combustible hydrocarbons are reduced when Diesel engine emitting soot and higher hydrocarbons. Waste gas scrubbers work In contrast to catalytic converters and recirculation methods, immediately when the engine is started as well as at all speeds and in all load ranges. Abgaswäscher werden daher beim Betrieb von Fahrzeugen mit Dieselmotor zum Tell vorgeschrieben, speziell bei Gabelstaplern im industriellen Einsatz zum Zwecke des Personen- und Gebäudeschutzes. Die Firma Steinbock beispielsweise installiert an Staplern großdimensionierte Wäscher, die laut Bedienungsanweisung (Anlage 1) mit reinem Wasser gefüllt werden sollen. Exhaust gas scrubbers are therefore used in the operation of vehicles with diesel engines prescribed for Tell, especially for forklifts in industrial use for Purposes of personal and building protection. The Steinbock company installed, for example Large-scale washers on forklifts, which according to the operating instructions (Appendix 1) should be filled with pure water. Mit dieser Füllung läßt sich nahezu kein Ruß zurückhalten! Aus dem Wasser kann nach einem Arbeitstag nur max. 1 Gramm Ru isoliert werden. Das Auspuffrohr ist verrußt, ebenso der Schleuderraum, was bei längerem Betreiben des Fahrzeugs zur Verstopfung des Schleuderraums und damit zum Ausfall des Motors führt. With this filling, almost no soot can be held back! From the Water can only be isolated a maximum of 1 gram of Ru after one working day. The exhaust pipe is sooty, as is the centrifugal chamber, which occurs when the vehicle is operated for a long time leads to clogging of the centrifugal chamber and thus to failure of the motor. Der Erfindung liegt die Aufgabe zugrunde, die Wirksamkeit der Abgaswäscher zu erhöhen. The invention is based on the object of improving the effectiveness of the exhaust gas scrubber to increase. Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß zur Reinigung der Abgase eine Tensid- resp. Tensid-Hydrogencarbonat-Füllung anstelle der Wasserfüllung eingesetzt wird. The object is achieved according to the invention in that for cleaning the exhaust gases a surfactant respectively. Surfactant-hydrogen carbonate filling instead of the water filling is used. Die erfindungsgemäßen Tensidfüllungen können den öligen Ruß weit besser benetzen und zurckhalten. Als Tenside eignen sich naturgemäß alle Seifen. Bevorzugt werden alkalische, nichtschäumende Tenside wie z. B. The surfactant fillings according to the invention can remove oily soot better wet and hold back. Naturally, all soaps are suitable as surfactants. Alkaline, non-foaming surfactants such as. B. RBS 50 von Roth oder AP 15 von Merck (Extran). Nach einem Arbeitstag lassen sich aus der Tensidfüllung ca.RBS 50 from Roth or AP 15 from Merck (Extran). After a day of work approx. 100 Gramm Ruß isolieren. Das Auspuffrohr bleibt rußfrei; somit dürfte die Tensidfüllung 100%ig arbeiten.Isolate 100 grams of soot. The exhaust pipe remains free of soot; thus should the surfactant filling work 100%. Neben Ruß können Dieselmotoren das Umweltgift Schwefeldioxid emittieren, für dessen Entfernung nicht Natronlauge oder Soda, sondern aus zwei Gründen Natriumhydrogencarbonat vorgeschlagen wird. Natronlauge oder Soda sind physiologisch nicht unbedenklich (Augenkontakt), während Natriumhydrogencarbonat unschädlich ist. Natronlauge oder Soda würden außerdem Kohlendioxid, die Hauptkomponente aller Abgase (neben Luftstickstoff) binden, was keineswegs erforderlich ist. Natriumhydrogencarbonat wandelt Schwefeldioxid in unschädliches Kohlendioxid um. Alkalische Tenside alleine würden auch Schwefeldioxid binden, jedoch wäre ihre Kapazität rasch erschöpft und die Wirksamkeit würde nachlassen. In addition to soot, diesel engines can emit the environmental toxin sulfur dioxide, for its removal not caustic soda or soda, but sodium hydrogen carbonate for two reasons is suggested. Sodium hydroxide or soda are not physiologically harmless (Eye contact), while sodium hydrogen carbonate is harmless. Caustic soda or Soda would also add carbon dioxide, the main component of all exhaust gases (besides atmospheric nitrogen) bind what is by no means necessary. Sodium hydrogen carbonate converts sulfur dioxide into harmless carbon dioxide. Alkaline surfactants alone would also produce sulfur dioxide bind, but their capacity would quickly be exhausted and the effectiveness would decrease. Abgaswäscher sind für Dieselmotoren nahezu unentbehrlich; auch für Benzinmotoren sind Vorteile erkennbar. Bei Verwendung von schwefelhaltigem Treibstoff vermag kein Reinigungskonzept das Umweltgift Schwefeldioxid zu entfernen, mit Ausnahme des Abgaswäschers. Nitrose Gase werden ebenfalls resorbiert und in Kohlendioxid umgewandelt. Nochmals sei auf die volle Funktionsfähigkeit des Wäschers hingewiesen, sofort beim Starten, bei allen Drehzahlen, in allen Lastbereichen. Exhaust gas washers are almost indispensable for diesel engines; also for Gasoline engines have obvious advantages. When using sulphurous fuel No cleaning concept can remove the environmental toxin sulfur dioxide, with one exception of the exhaust gas scrubber. Nitrous gases are also reabsorbed and converted into carbon dioxide converted. Again, the full functionality of the scrubber should be pointed out, immediately when starting, at all speeds, in all load ranges. Die Erschöpfung der Tensidfüllung kann z. B. durch den Farbindikator Bromthymolblau sichtbar gemacht oder über die Abnahme des pH-Wertes physikalisch gemessen werden. Frostschutzmittel beeinträchtigen die Wirksamkeit der Füllung nicht. The exhaustion of the surfactant filling can, for. B. by the color indicator Bromthymol blue made visible or physically via the decrease in the pH value be measured. Antifreeze does not affect the effectiveness of the filling. Die mit der Erfindung erzielten Vorteile bestehen in einer wesentlich besseren Resorption der emittierten Schadstoffe aus Verbrennungsmotoren, speziell aus Dieselmotoren, zum Zwecke des Personen-, Geräte-, Gebäude- und Umweltschutzes. Zudem dürfte sich die erhöhte Permeabilität der Tensidfüllung für die nichtresorbierten Restgase vorteilhaft auf den Kraftstoffverbrauch des Motors auswirken. The advantages achieved by the invention consist in one essential better absorption of the pollutants emitted from internal combustion engines, especially from diesel engines, for the purpose of protecting people, equipment, buildings and the environment. In addition, the increased permeability of the surfactant filling for the non-resorbed Residual gases have a beneficial effect on the fuel consumption of the engine.
