Description

Verfahren zur Beseitigung gasförmiger Kontaktgifte aus Röstgasen Gegenstand der Erfindung ist ein Verfahren zur Beseitigung gasförmiger Kontaktgifte aus Röstgasen, insbesondere Blenderöstgasen, die nach vorangehender Berieselung mit Schwefelsäure einem Elektrofilter zur Abscheidung von Arsen, Selen o. dgl. zugeführt werden. Die Erfindung wird darin gesehen, daß die schädlichen Gasbestandteile, wie z. B. Fluor, Chlor u. dgl., nach der elektrischen Arsen- oder Selenabscheidung oder, wenn die Entarsenierung stufenweise durchgeführt wird, im Verlaufe derselben, beispielsweise nach der ersten Stufe, in einem mit Füllkörpern versehenen Rieselturm an dessen Füllmaterial gebunden werden.Process for the elimination of gaseous contact poisons from roasting gases Subject the invention is a method for removing gaseous contact poisons from roasting gases, in particular blender roast gases, which after previous sprinkling with sulfuric acid an electrostatic precipitator for separating arsenic, selenium or the like. the Invention is seen in the fact that the harmful gas components such. B. fluorine, Chlorine and the like, after the electrical arsenic or selenium separation or, if the Dearsenation is carried out in stages, in the course of the same, for example after the first stage, in a trickle tower provided with random packings Fill material to be bound.

Infolge der weitgehenden Arsenniederschlagung in der ersten elektrischen Reinigerstufe fallen im nachgeschalteten Berieselungsturm nur noch so verschwindend geringe Mengen von Arsen o. dgl. an, daß die Turmpackung, die aus Glas, Quarz, Koks oder ähnlichem Material besteht, durch Ablagerungen in ihrer mechanischen oder chemischen Wirksamkeit nicht beeinträchtigt werden können.As a result of extensive arsenic precipitation in the first electrical The detergent level only disappears in the downstream sprinkler tower small amounts of arsenic o. the like. That the tower packing, which is made of glass, quartz, coke or similar material, by deposits in their mechanical or chemical Effectiveness cannot be impaired.

Da ferner die dem nachgeschalteten Berieselungsturm vorangehende elektrische Reinigerstufe eine starke Abscheidung von Säurenebeln zur Folge hat und auch für die Entfernung von SO, sorgt, so kann man den nachgeschalteten Turm mit Wasser berieseln, das sich nicht oder kaum mit Säure anreichert. Die Temperatur bleibt also imTurm so niedrig, daß die chemische Reaktion zwischen Fluor und der Turmpackung nichts von ihrer Wirksamkeit verliert und die Aufnahme schädlicher Gasbestandteile durch die Berieselungsflüssigkeit möglich ist.Furthermore, since the electrical upstream of the downstream sprinkler tower Cleaning stage has a strong separation of acid mist and also for the consequence the removal of SO, ensures, so you can sprinkle the downstream tower with water, which is not or hardly enriched with acid. So the temperature stays in the tower so low that the chemical reaction between the fluorine and the tower packing is nothing loses its effectiveness and the absorption of harmful gas components the sprinkling liquid is possible.

Die wiederholte Berieselung von Röstgasen mit Wasser oder Schwefelsäure im Verlaufe ihrer elektrischen Feinreinigung ist bekannt. Diese Berieselung-allein genügt aber nicht, um die im Gas vorhandenen Kontaktgifte zu beseitigen, vielmehr muß die Berieselung gemäß der Erfindung in einem mit Füllkörpern ausgerüsteten Turm vorgenommen werden, um die ausgewaschenen schädlichen Bestandteile des Gases mechanisch oder chemisch an das Füllmaterial zu binden.The repeated sprinkling of roasting gases with water or sulfuric acid in the course of their electrical fine cleaning is known. This sprinkling-alone but is not enough to eliminate the contact poisons present in the gas, rather the sprinkler system according to the invention must be in a tower equipped with random packings be made to the washed out harmful constituents of the gas mechanically or to bond chemically to the filler material.
