Verfahren zur chemischen h1ntgiftunj der Abgase von hraf tf ahrz eug-Verbrennungsnas chinen und stationären veizanlagen sowie Filtereinrichtungen zur Burchführung der Verfahren.Process for the chemical anti-poisoning of the exhaust gases from hraf tf ahrz eug -burnnas chines and stationary heating systems as well as filter devices for carrying out the Procedure.
Die erfindung bezieht sich auf neuartige Verfahren zur chemischen entgiftung der Abgase von Kraftfahrzeug-Verbrennungsmaschinen und stationären Heizanlagen sowie Filtereinrichtungen zur Durchführung der Verfahren.The invention relates to novel processes for chemical detoxification of exhaust gases from vehicle internal combustion engines and stationary heating systems as well as filter devices for carrying out the process.
Die Probleme und Gefahren, die für Hensoh, einer und Pflanzenwelt durch die giftige Verschmutzung der Atemluft bestehen, sind hinreichend bekannt. Insbesondere Kraftfahrzeug-Verbrennungsmaschinen und Öl- bzw. Gasfeuerungsanlagen verseuchen täglich mit unkontrollierten Mengen Kohlenwasserstoff, Kohlenmonoxyd, Kohlendioxyd und Schwefelabgasen unsere Atemluft.The problems and dangers for Hensoh, an and flora through the toxic pollution of the air we breathe are well known. In particular, motor vehicle internal combustion engines and oil or gas firing systems contaminate daily with uncontrolled amounts of hydrocarbons, carbon monoxide, Carbon dioxide and sulfur fumes the air we breathe.
Bisher bekannte Industrie-Filteranlagen beschreiten den Weg, Schadstoffe abzusondern, um sie dann Vernichtungsanlagen oder Deponien zuzuführen. Solche Anlagen sind einmal für die erfindungsgemäßen Anwendungen nicht einzusetzen und sind weiterhin unbefriedigend, weil nach diesen Verfahren die aufgefangenen Schadstoffe noch nicht vernichtet sind und beispielsweise Verbrennungsanlagen zugeführt werden müssen.Previously known industrial filter systems are treading the path of pollutants to separate them in order to then send them to destruction facilities or landfills. Such plants are once not to be used for the applications according to the invention and continue to be unsatisfactory, because after this process the pollutants are not yet collected destroyed and have to be supplied to incineration plants, for example.
Die weiterführenden Überlegungen auf diesem Gebiet müssen dahin gehen, eine Entgiftungsamlage zu finden, die schon während des Betriebes vor dem Austritt der Abgase die fachaclstoffe durch chemischen Reaktionen fest zu binden und/oder durch das Entstehen anderer chemischer Verbindungen unschädlich zu machen.The further considerations in this area must go as follows: to find a detoxification system that already exists during the operation before the exit of the exhaust gases to bind and / or firmly bind the specialist substances through chemical reactions to render them harmless by the formation of other chemical compounds.
bberrasenend hat sich gezeigt, daß durch den Einsatz von Oxyden oder Hydroxyde eines oder mehrerer Erdalkaleide oder anderer grenzflächenaktiven Substanzen in Verbindung mit Wasser oder Wasserdampf un/oder Substanzen mit Redoxpotential unter wahlweiser Beimischung von chemischen Substanzen zur Steuerung und Ergänzung der auszulösenden Reaktionen den durchlaufenden Abgasen aus Verbrennungsmotoren oder stationären @eizanlagen die lebensfeindlichen Bestandteile derselben, wie Kohlenmonoxyd, Eohlendioxyd, unverbrannte Kohlenwasserstoffe, Schwefel und andere durch chemische und/oder physikalische Bindungen derselben an den genannten Substanzen oder Oxydationen entzogen werden, so daß diese entgifteten Abgase nach dem Passieren eines beweglichen Bandfilters gereinigt ins Freie ausströmen können. Hierbei können diese Reaktionsmittel gemeinsam und gleichzeitig oder zeitlich und räumlich getrennt zum Einsatz kommen.It has been shown that the use of oxides or Hydroxides of one or more alkaline earths or other surface-active substances in connection with water or steam and / or substances with redox potential with optional admixture of chemical substances for control and supplementation the reactions to be triggered the exhaust gases passing through from internal combustion engines or stationary heating systems, the life-threatening components of the same, such as carbon monoxide, Carbon dioxide, unburned hydrocarbons, sulfur and others by chemical and / or physical bonds of the same to said substances or oxidations be withdrawn, so that these detoxified exhaust gases after passing a moving Cleaned belt filter can flow out into the open air. Here, these reactants can be used together and at the same time or at different times and locations.
Beispiel 1 Calciumoxyd ( Weißfeinkalk ) reagiert mit Wasser oder Wasserdampf zu Calciumhydroxyd und bindet gasförmige Kohlenwasserstoffe, wobei das mit Kchlcnwasserstoff beladene Hydroxyd seine Fähigkeit zu carbonisieren nicht einbüßt und mit den in den Abgasen befindlichen Kchlenmonoxyd und Kchlendioxyd eine feste Verbindung zu Calciumkarbonat eingeht.Example 1 Calcium oxide (white fine lime) reacts with water or water vapor to calcium hydroxide and binds gaseous hydrocarbons, whereby the hydroxide loaded with hydrogen chloride does not show its ability to carbonize forfeited and one with the chloride monoxide and chloride in the exhaust gases forms a firm bond with calcium carbonate.
Beispiel 2 Bubstanzen mit Redoxpotential, wie kaliumperm,anganat und/oder Kethylen blau und/oder Ozon und/oder Wasserstoffsuperoxyd kommen zum Einsatz, die eine Oxydation von Kohlenmonoxyd, Schwefel und Blei bewirken.Example 2 Substances with redox potential, such as potassium perm, anganat and / or Kethylene blue and / or ozone and / or hydrogen peroxide are used cause an oxidation of carbon monoxide, sulfur and lead.
Wie schon erwähntm,können diein den Beispielen 1 und 2 beschriebenen Verfahren auch gemeinsam zum Einsatz kommen.As already mentioned, those described in Examples 1 and 2 can be used Process can also be used together.
In der Zeichnung sind zur Durchführung der Verfahren drei Bntgiftungs und Filteranlagen für Abgase beispielsweise dargestellt. Es zeigt Fig. 1 eine Entgiftungs- und Filteranlage für die Abgase von Kraftfahrzeugen, Fig. ia eine dem gleichen Zweck dienende Entgiftungs und Filteranlage und Fig. 2 eine Entgiftungs- und Filteranlage für stationçre Heizungen.In the drawing there are three detoxification measures for carrying out the procedures and filter systems for exhaust gases are shown for example. It shows Fig. 1 a detoxification and filter system for the exhaust gases from motor vehicles, Fig. ia one for the same purpose serving detoxification and filter system and Fig. 2 a detoxification and filter system for stationary heating.
