Abstract

Destruction of harmful materials (I) and recovery of wash liquor cpds. in gas scrubbers is effected by passing the liquor (continuously) into a vessel and burning off (I) without environmental pollution, leaving the residue, e.g. Na2O Na2CO3 if NaOH soln. is used, in the vessel, for the prodn. of a fresh NaOH and/or Na2CO3 soln. The equipment used has an oil- or gas-fired furnace with inlet for the liquor, (movable) tanks and guide rails and refractory combustion chambers. Process, which is used in associated with refuse incinerators, allows the waste liquor components to be recycled without the liquor itself, Steam is expelled and (I), such as phenol and/or HCHO, burnt off.

Description

Beschreibung und @rläuterung zur PatentanmeldungDescription and explanation of the patent application

Vriahren und Vorrichtung zur Vernichtung von Schadstoffen in Gas-Waschlaugen und Gewinnung der Waschlaugen-Substanz".Tube and device for the destruction of pollutants in gas washing liquors and recovery of the wash liquor substance ".

Zur Auswaschung von Schadstoffen wie Phenol, Formaldehyd und dergleichen in Abgasanlagen vewendet man vielfach Waschlaugen.For washing out pollutants such as phenol, formaldehyde and the like Washing lye is often used in exhaust systems.

Uberwiegend wird Natronlauge benutzt.Sodium hydroxide is predominantly used.

Das Vernichten dieser waschlaugen wird fast ausschließlich in Müllverbrennungsanlagen vorgenommen.The destruction of this wash liquor is almost exclusively in waste incineration plants performed.

Hier bewirkt die Waschlaugen-Verbrennung vielfach in Verbindung mit anderen sublimierten Stoffen eine Inkrustation an den Wärmetauschflächen, verursacht Schäden am Mauerwerk der Brennkammer und ermöglicht keine Rückführung der Grundsubstanzen, die wieder zu einer Laugenherstellung verwendet werden könnten.Here, the washing liquor incineration works in conjunction with other sublimated substances cause incrustation on the heat exchange surfaces Damage to the brickwork of the combustion chamber and does not allow the basic substances to be returned, which could be used again for a lye production.

Um aiesen Nachteil zu beseitigen und gleichzeitig anlagentechnisch integriert ohne Abwasser im Recycling fahren zu können, wird erfindungsgemäß vorgeschlagen, ein Verfahren zu verwenden, das entsprechend beiliegender Skizze durchgeführt wird.In order to eliminate this disadvantage and at the same time in terms of plant engineering integrated without being able to run wastewater in recycling, it is proposed according to the invention, to use a procedure that is carried out according to the attached sketch.

In der beiliegenden Skizze ist dargestellt mit 1 ein Verbrennungsofen, mit 2 die Gas- oder Ölbrenner, mit 3 die Zuführung der Waschlauge illit den Schadstoffen, z. B. Phenol una Formaldehyd, mit 4 ein fahrbarer Wagen, der in den Ofen herein- und herausgetahren erden kann, mit 5 eine Schienenführung, mit 6 ein feuerfester Brennkasten, der mit dem Einlaufrohr 3 in Verbindung steht.In the attached sketch is shown with 1 an incinerator, with 2 the gas or oil burner, with 3 the supply of the washing liquor with the pollutants, z. B. phenol and formaldehyde, with 4 a mobile cart that enters the furnace and can be moved out, with 5 a rail guide, with 6 a fireproof Burning box, which is connected to the inlet pipe 3.

Verfahrensablauf.Process flow.

Die mit Schadstoffen angereicherte Waschlauge wird bei 3 in dem feuerfesten Brennkasten oder auch Rinne oder Rohr kontinuierlich zugeführt Im Ofen wird über die Brenner eine Temperatur erzeugt, die zur Wasserverdampfung und Verbrennung der Schadstoffe wie Phenol und/oder Formaldehyd ausreicht.The washing liquor enriched with pollutants is at 3 in the refractory Burning box or gutter or pipe is fed continuously the burner creates a temperature that is conducive to water evaporation and combustion of the Pollutants such as phenol and / or formaldehyde are sufficient.

Nach der Anreicherung des feuerfesten Brennkastens mit deli Rückstand der Waschlauge, bei Natronlauge z. B. Natriumoxyd/ Natriumcarbonat (Na2O/Na2CO3>, wird der gesamte Brennkasten 6 aus dem Ofen herausgezogen und durch einen neuen eingeschobenen ersetzt oder wird im Olen nach Abstellen der Feuerung oder außerhalb des Ofens erkaltet. Der gesamte Brennkasten wird als Na2O/Na2CO3-Salzträger in die Waschflüssigkeit der daneben aufgestellten Rauchgaswaschanlage eingetaucht, das Natriutnoxyd bzw. Na2CO3löst sich in Wasser, bildet Natronlauge bzw. Natriumcarbonatlauge und kann somit wieder für den viaschprozeß der Gase eingesetzt werden Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellte und beschriebene Ausbildungsform beschränkt sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, Waschlauge, die mit Schadstoffen belastet ist, vorzugsweise Natronlauge, in einen unter entsprechender Temperatur stehenden Behälter einfließen zu lassen, so daß die Schadstoffe verbrennen, die Flüssigkeit verdunstet und das zurückgebliebene Natriumoxyd bzw. Natriumcarbonat als Bildner von Natronlauge bzw.After enriching the refractory burning box with deli residue the washing liquor, for caustic soda z. B. Sodium Oxide / Sodium Carbonate (Na2O / Na2CO3>, the entire combustion box 6 is pulled out of the furnace and replaced with a new one inserted or replaced in the oil after the furnace has been switched off or outside the stove has cooled down. The entire burning box is put into the as Na2O / Na2CO3 salt carrier The washing liquid of the flue gas washing system installed next to it is immersed, the Sodium oxide or Na2CO3 dissolves in water, forms caustic soda or sodium carbonate lye and can thus be used again for the gas wash process. Of course the invention is not limited to that illustrated and described in detail above Form of training limited but numerous changes are possible without However, to deviate from the basic idea, washing liquor, which is loaded with pollutants is, preferably sodium hydroxide, in a standing at the appropriate temperature To let the container flow in so that the pollutants burn the liquid evaporates and the remaining sodium oxide or sodium carbonate as a generator of caustic soda or

Natriumcarbonatlauge Anwendung finden kann.Sodium carbonate can be used.
