Description

Verfahren zum Entstauben der Abgase bei Trocknern. Die Erfindung bezieht sich auf ein Verfahren zum Entstauben der Abgase bei Trocknern, bei dem das zu trocknende Gut selbst als Filtermasse benutzt wird.Process for dedusting exhaust gases from dryers. The invention relates on a process for dedusting the exhaust gases in dryers, in which the to be dried Good itself is used as a filter mass.

Die bisher vorgeschlagenen Verfahren dieser Art haben zu einem Erfolg meistens nicht führen können, weil bei ihnen eine ausreichende Filterwirkung nicht möglich ist.The previously proposed methods of this type have been successful mostly not able to lead, because they do not have a sufficient filter effect is possible.

Diesem Mangel soll gemäß der Erfindung dadurch abgeholfen werden, daß das als Filtermasse dienende Gut, z. B. stark wasserhaltige Braunkohle, durch einen von zwei luftdurchlässigen Wänden gebildeten Zwischenraum bewegt wird, den die Trocknerabgase durchqueren. In der Zeichnung ist eine dem neuen Verfahren dienende Vorrichtung beispielsweise dargestellt.According to the invention, this deficiency is to be remedied by that that as a filter mass serving good, e.g. B. highly hydrous Brown coal, formed by a space formed by two air-permeable walls is moved through which the dryer exhaust gases traverse. In the drawing, one is the new one Process serving device shown for example.

Über dem Trocknerraum ist auf einem ringförmigen Bodenblech J eine senkrecht stehende Trommel A aus Siebblech oder sonstigem luftdurchlässigen Stoff fest eingebaut. Gleichachsig zu dieser Trommel A bewegt sich eine um eine senkrechte Welle C drehbar angeordnete Trommel B aus ebenfalls luftdurchlässigem Stoff. Der Abstand zwischen der äußeren Trommel A und der inneren Trommel B ist so gewählt, daß er der erforderlichen Stärke der Filterschicht entspricht. Über der ringförmigen Filterschicht ist in der Decke K eine Zubringöffnung mit anschließendem Behälter H für die Einbringung des zu trocknenden Gutes angebracht. Die Verbindung der inneren Trommel B mit der Welle C erfolgt durch die Arme D. An einem der unteren Arme D ist ein über dem Boden J sich bewegendes Kratzerblech E angeordnet, welches bei Drehung der Trommel B eine genau regelbare Menge des zu trocknenden Gutes von dem Bodenblech J abstreicht und in den Trocknerraum befördert. Die Drehung der Trommel B soll bewirken, daß sich die Filterfläche nicht versetzt und das Gut in dem ringförmigen Filterraum stets in Bewegung bleibt und damit eine Stockung in der Zuführung frischen Gutes verhütet wird.Above the dryer room there is one on an annular floor panel J Vertical drum A made of sieve plate or other air-permeable material permanently installed. Coaxially to this drum A moves a vertical one Shaft C rotatably arranged drum B also made of air-permeable fabric. Of the The distance between the outer drum A and the inner drum B is chosen so that it corresponds to the required thickness of the filter layer. Above the annular The filter layer is a feed opening in the ceiling K with a subsequent container H attached for the introduction of the goods to be dried. The connection of the inner Drum B with shaft C takes place through arms D. On one of the lower arms D a scraper plate E moving above the floor J is arranged, which at Rotation of the drum B a precisely controllable amount of the goods to be dried by the Wipes off floor pan J and transports it to the dryer room. The rotation of the drum B is intended to ensure that the filter surface does not shift and the material in the annular The filter chamber always remains in motion and thus a blockage in the supply is fresh Good is prevented.

Die entstaubten Abgase sammeln sich in dem zwischen der Trommel A und dem äußeren Mantel G gebildeten Raum L und entweichen von letzterem durch die Rohrleitung F.The dust-free exhaust gases collect in the between drum A and the outer jacket G formed space L and escape from the latter through the Pipe F.

PATENTANSPRUCH: Verfahren zum Entstauben der Abgase bei Trocknern, bei dem das zu trocknende Gut selbst als Filtermasse benutzt wird, dadurch gekennzeichnet, daß das als Filtermasse dienende Gut, z. B. stark wasserhaltige Braunkohle, durch einen von zwei luftdurchlässigen Wänden gebildeten Zwischenraum bewegt wird, den die Trocknerabgase durchqueren. PATENT CLAIM: A method for dedusting the exhaust gases from dryers, in which the material to be dried is used itself as a filter material, characterized in that the material used as a filter material, e.g. B. highly water-containing lignite, is moved through a space formed by two air-permeable walls, which the dryer exhaust gases traverse.
