Abstract

The adsorption process for cleansing air from container washing units, comprises using a hydrophobic zeolite as the adsorber and further treating the concentrated impurities following desorption. The desorption preferably takes place at 50-500 deg C over 10 minutes to 8 hours. The washing unit is preferably used for steel and plastic barrels, paint containers, transport containers, etc..

Description

Die Erfindung bezieht sich auf ein Verfahren zur Reinigung des Abluftstroms aus Behälterwaschanlagen. Es ist uns bisher noch kein Verfahren bekannt, welches die Abluft aus Behälterwaschanlagen reinigt. Diese Aussage stützt sich auf einen gestellten Förderantrag bei der Deutschen Bundesstiftung Umwelt, in Osnabrück, mit dem Titel "Abluftreinigung für automatische Faßreinigungsanlagen", indem bei einer durchgeführten Untersuchung kein Stand der Technik für diese Problemstellung nachgewiesen werden konnte. Zusätzlich ist nach Aussagen der AG Behälterreinigung keine derzeitige Anlage in Deutschland mit einer Abgasreinigung ausgerüstet. Der bei Behälterwaschanlagen vorkommende Abluftstrom kann sich aus bis zu 100 verschiedenen organischen Verbindungen zusammensetzen, die sich in ihren physikalischen, chemischen und biologischen Eigenschaften voneinander unterscheiden, je nach ehemaligem Behälterinhalt und der Häufigkeit dieser. Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Reinigung dieses Abluftstroms zu entwickeln um den Bestimmungen des Bundesimmissionsgesetzes gerecht werden zu können. Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Weitere, vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen. In Weiterbildung der Erfindung hat es sich als besonders vorteilhaft erwiesen als Adsorbermaterial Wessalith Day von der Fa. Degussa einzusetzen.The invention relates to a method for cleaning the exhaust air stream Container washing systems. So far we are not aware of any process that would Exhaust air from tank washers cleans. This statement is based on a statement Funding application to the German Federal Environmental Foundation, in Osnabrück, entitled "Exhaust air purification for automatic drum cleaning systems" by performing one No state of the art investigation for this problem can be proven could. In addition, according to the AG Container Cleaning, there is no current facility in Germany equipped with an exhaust gas cleaning system. The one with container washing systems Existing exhaust air flow can consist of up to 100 different organic Compound compounds that are in their physical, chemical and distinguish biological properties from each other, depending on the former container content and the frequency of this. The invention has for its object a method for Purification of this exhaust air flow to develop the provisions of To be able to comply with the Federal Immission Act. This task is accomplished by the Features of claim 1 solved. Further advantageous embodiments of the invention can be found in the subclaims. In a further development of the invention, it has proven to be Wessalith Day from Degussa has proven particularly advantageous as adsorbent material to use.

Weitere Einzelheiten der Erfindung werden anhand der nachfolgenden Beschreibung und der Abb. 1 erläutert:Further details of the invention are explained on the basis of the following description and FIG. 1:

Der Abluftstrom von einer Behälterwaschanlage aus einem Faßrekonditionierungsbetrieb wird durch einen Adsorberbehälter geleitet. In dem Adsorberbehälter werden die Schadstoffe von dem erfindungsgemäßen Verfahren, hydrophobe Zeolithe, adsorbiert. Die Adsorption wird so lange durchgeführt bis die Adsorptionskapazität der Zeolithe erschöpft ist, z. B. tagsüber. Nachts werden dann die Schadstoffe desorbiert, indem Frischluft auf 500°C erhitzt und in entgegengesetzter Richtung den Adsorber durchströmt. Die aufkonzentrierten Schadstoffe können anschließend in einer regenerativen, rekuperativen oder katalytischen Nachverbrennung chemisch umgesetzt werden. Am Tage beginnt der Kreislauf von neuem.The exhaust air flow from a container washing system from a barrel reconditioning company is passed through an adsorber tank. In the adsorber tank Pollutants adsorbed by the process according to the invention, hydrophobic zeolites. The Adsorption is carried out until the adsorption capacity of the zeolites is exhausted is, e.g. B. during the day. The pollutants are then desorbed at night by adding fresh air 500 ° C heated and flows through the adsorber in the opposite direction. The Concentrated pollutants can then be used in a regenerative, recuperative or catalytic afterburning can be implemented chemically. The day begins Cycle again.
