Description
Verfahren zur vollkommenen Entstaubung von Luft und Gasen.Process for the complete dedusting of air and gases.
Bekanntlich werden bei der Entstaubung von Luft oder Gasen bei deren Durchleitung durch viskos benetzte Filter die feinsten Teilchen der schwebenden Stoffe vom Filter nicht immer vollständig zurückgehalten. It is known that in the dedusting of air or gases in their Passing through viscous wetted filters the finest particles of the floating Substances not always completely retained by the filter.
Nach vorliegender Erfindung läßt sich eine restlose Reinigung von mit Staub beladener Luft oder Gasen durch eine Vorbehandlung des Gases in mit Öl oder ähnlich viskosem Material benetzten Oberflächenfiltern ermöglichen. According to the present invention, a complete purification of dust-laden air or gases by pretreating the gas with oil or similar viscous material allow surface filters wetted.
Diese Vorbehandlung besteht in der Zumischung von Gasen, Dämpfen oder auch von Staub verschiedener Art allein oder gemischt in feinster Form zum Rohgas, bevor es durch das Filter tritt. Je nach den Verhältnissen oder der Eigenart des zu bindenden Staubes richtet sich Art und Anwendungsweise (gleichzeitig oder nacheinander) der Zumischstoffe. So kann z. B. zementstaubhaltige Luft mit Öldämpfen oder Kupferoxydstaubluft mit Schwefeldioxyd vorbehandelt werden. Die beste Einwirliung wird dadurch erzielt, daß die Beimischung kurz nach der Entstehung des betreffenden Stoffes oder der betreffenden Aggregatform erfolgt. This pretreatment consists of adding gases and vapors or also from dust of different kinds alone or mixed in the finest form for Raw gas before it passes through the filter. Depending on the circumstances or the peculiarities of the dust to be bound depends on the type and application (at the same time or one after the other) of the admixtures. So z. B. air containing cement dust with oil vapors or copper oxide dust air can be pretreated with sulfur dioxide. The best induction is achieved that the admixture shortly after the emergence of the relevant Substance or the relevant aggregate form takes place.
Durch solche Zuführung zweiter oder dritter Stoffe in feinster Verteilung zu Staub von ebenfalls hohem Dispersionsgrad wird erreicht, daß durch Zusammenlagerung von Staubteilchen verschiedener spezifischer Wärme oder durch chemische Oberflächeneinwirkung oder beides zusammen die physikalischen Eigenschaften (Volumen, Masse, Benetzbarkeit) so weit verändert werden, daß die Staubteilchen beim nachherigen Durchgang durch ein viskos benetztes Filter festgehalten werden. Außerdem ballen sich durch die Oberflächenbeeinflussung die Teilchen leichter zusammen und unterstützen dadurch die Wirksamkeit des Verfahrens. Such a supply of second or third substances in the finest distribution to dust of likewise high degree of dispersion is achieved that by storage together from dust particles of different specific heat or from chemical surface effects or both together the physical properties (volume, mass, wettability) can be changed so far that the dust particles through the subsequent passage a viscous wetted filter can be held. In addition, the Surface influencing the particles together more easily and thereby support the effectiveness of the procedure.
Durch dasselbe wird somit der Anwendungsbereich viskos benetzter Filter auch"auf Staub von allergeringster Teilchengröße und geringer Affinität zu Ö1 ausgedehnt. The area of application is thus more viscously wetted by the same Filters also "apply to extremely small particle size and low affinity dust Ö1 extended.
Durch aufeinanderfolgende Mischung mit verschiedenen Stoffen läßt sich auch eine Trennung eines Staubgemisches vornehmen. By successive mixing with different substances leaves also undertake a separation of a dust mixture.
Ein besonderer Vorteil bei dem Verfahren ist auch, daß bei Verwendung von Öldampf eine außerordentlich geringe Menge zur Bindung der Staubteilchen genügt, da trotz sicht-Ear stärkeren Zusammenhanges derselben die Ölmenge quantitativ kaum feststellbar ist. A particular advantage of the method is that when it is used an extremely small amount of oil vapor is sufficient to bind the dust particles, since in spite of the stronger connection between them, the quantity of oil hardly quantitatively is detectable.
Die chemische Einwirkung auf die Staubteilchen erstreckt sich nur auf deren Oberfläche, und die Art des Zumischstaubes läßt sich auch dem besonderen Zweck entsprechend wählen, so daß das Verfahren in keinem Falle die Verwendbarkeit des abgeschiedenen Gutes beeinträchtigt. The chemical action on the dust particles only extends on their surface, and the type of dust added can also be determined by the special Choose the purpose accordingly, so that the process in no case the usability of the separated material impaired.
