Description

Trocknungsverfahren Der Wirkungsgrad eines Trocknungsverfahrens gemäß Patent 644635, bei dem das gegen Erde isolierte -zu trocknende Gut mit einem elektrisch einpolig aufgeladenen gasförmigen Stoff in Berührung gebracht wird, läßt sich erfindungsgemäß dadurch erheblich steigern, daß alle im Wirkungsbereich der Aufladung befindlichen Flächen der Trocknungsanlage geerdet werden. Ganz besonders wirkungsvoll wird diese Maßnahme, wenn gemäß dem Zusatzpatent 676481 nur das Trocknungsgut, und zwar his zu einer Spannung von mindestens 5oo V, einpolig aufgeladen wird.Drying process The efficiency of a drying process according to Patent 644635, in which the material to be dried is insulated from earth with an electrically unipolar charged gaseous substance is brought into contact, according to the invention thereby increase considerably that all are located in the area of action of the charge Surfaces of the drying system must be earthed. This is particularly effective Measure if, according to the additional patent 676481, only the material to be dried, namely his is charged to a voltage of at least 5oo V, single-pole.

Einige Ausführungsformen des neuen Verfahrens seien an Hand der schematischen Zeichnung erläutert.Some embodiments of the new method are based on the schematic Drawing explained.

In Abb. i ist mit a das gegen Erde isolierte Trocknungsgut bezeichnet, durch das mittels eines Gebläses b Luft (oder ein anderes gasförmiges Mittel) hindurchgesaugt wird. Gemäß dem Zusatzpatent wird nur das zu trocknende Gut einpolig aufgeladen. Dieses befindet sich in einem Kasten c aus Isolierstoff, der in dem Raum d aufgestellt ist. Die Innenflächen dieses Raumes haben einen metallischen Belag e, der an Erde gelegt ist. Die Zuleitungs- und Ableitungsrohre für die Luft bestehen aus Metall und sind ebenfalls an Erde gelegt; ebenso haben die Außenflächen des Kastens c einen metallischen Belag f, der in die Erdung einbezogen ist.In Fig. I, the item to be dried, isolated from the ground, is designated with through which air (or some other gaseous medium) is sucked through by means of a fan b will. According to the additional patent, only the goods to be dried are charged unipolar. This is located in a box c made of insulating material, which is placed in the room d is. The inner surfaces of this room have a metallic covering that is attached to the earth is laid. The supply and discharge pipes for the air are made of metal and are also laid on earth; likewise, the outer surfaces of the box c have one metallic covering f, which is included in the grounding.

Die Ausführungsform nach Abb.2 unterscheidet sich von der vorigen dadurch, daß auch die zur Trocknung benutzte Luft elektrisch einpolig aufgeladen wird, und zwar mittels der elektrisch aufgeladenen Hohlkugel ä, die in die Zuleitung der Luft eingebaut ist. Derjenige Teil der Luftzuleitung, der mit dem die Hohlkugel g enthaltenden Teil beginnt, besteht aus Isolierstoff, der aber außen metallisch umkleidet ist, so daß auch die Außenflächen dieser Zuleitung in die Erdung einbezogen sind.The embodiment according to Fig.2 differs from the previous one in that the air used for drying is also electrically charged with one pole is, by means of the electrically charged hollow ball ä, which is in the supply line built into the air. That part of the air supply line with which the hollow sphere g begins, consists of insulating material, but the outside is metallic is encased so that the outer surfaces of this supply line are also included in the grounding are.

Bei der Ausführungsform nach Abb. 3, die im übrigen wieder der Abb. i entspricht, wird durch eine hier hohlkugelförmige Düse h der Luft noch Wasser in zerstäubtem Zustand beigemischt, wie es bei einer Ausführungsform des Hauptpatents ebenfalls geschieht.In the embodiment according to Fig. 3, the rest of the Fig. i, the air is still water through a hollow spherical nozzle h here admixed in the atomized state, as in one embodiment of the main patent also happens.
