Description

Kühlturm für Laugen Die Kühlung von Laugen muß so geschehen, daß die Umgebung durch den Austritt mitgerissener Teilchen nicht belästigt wird. Zur Zeit geschieht diese Kühlung durchweg in Rückkühlanlagen, die die Form eines Kaminkühlers haben. Rieseleinbauten fehlen darin, und die Lauge wird dem Luftstrom in feiner Verteilung entgegengeführt. Dabei läßt es sich aber nicht vermeiden, daß sich dem Luftstrom bei der Erwärmung feine Laugentröpfchen aufladen, und man hat, um diese Lauge vor dein Austritt ins Freie abzufangen, Schwadenfänge angeordnet, die jedoch auch nur eine unvollkommene Gewähr für die Zweckerfüllung bieten. Sie lassen Lauge durch, die alsdann die Nachbarschaft belästigt, den Pflanzenwuchs schädigt und dergleichen Schäden mehr verursacht. Dazu kommt, daß die Schwadenfänge Salz ansetzen, also Reinigungsunkosten verursachen, und der Kühlraum muß grob bemessen sein, um das Mitreißen von Laugeteilchen möglichst zu verhindern. Diese großen Abmessungen bedingen hohe Kosten.Cooling tower for caustic solutions The cooling of caustic solutions must be done in such a way that the Environment is not bothered by the escape of entrained particles. For now This cooling takes place consistently in recooling systems that take the form of a chimney cooler to have. There is no trickle installation, and the lye becomes finer in the air flow Distribution countered. But it cannot be avoided that the The air flow charges fine lye droplets when it is heated, and you have to do this To catch the lye before it escapes into the open air, swath catchers arranged, however also only offer an imperfect guarantee for the fulfillment of the purpose. You leave lye which then annoys the neighborhood, damages the vegetation and the like Damage caused more. In addition, the steam traps add salt, so cleaning costs cause, and the cooling space must be large to prevent the entrainment of lye particles to prevent as much as possible. These large dimensions result in high costs.

Die erwähnten Nachteile werden durch die Erfindung vermieden, und zwar dadurch, daß die aus dem Kühlraum kommende Kühlluft (der Schwaden) nach Abkühlung der Lauge unmittelbar einem Rieselwerk zugeführt wird, wo sie durch Auswaschen vom Laugegehalt befreit wird. Erst. dann wird sie ins Freie gelassen.The disadvantages mentioned are avoided by the invention, and by the fact that the cooling air (the steam) coming from the cold room has cooled down the liquor is fed directly to a trickling plant, where it is washed out by the Lye content is freed. First. then it is let out.

Es ist zwar bereits bekannt, einem Rieselwerk ein zweites Rieselwerk nachzuschalten, das von der im ersten gekühlten Luft durchströmt wird; jedoch geschach das zu dem Zweck der Wärmerückgewinnung, und zwar in der Weise" daß auch dem zweiten Rieselwerk Lauge zugeführt wurde. Es war also durch die vorbekannte Einrichtung nicht möglich, die Luft von feinen Laugeteilchen zu reinigen, da sie sich im zweiten Rieselwerk mit solchen wieder anreichern mußte. Demgegenüber wird das zweite Rieselwerk bei der Erfindung nur mit Wasser beschickt.It is already known that a sewage plant has a second sewage plant downstream through which the air cooled in the first flows; however schach that for the purpose of heat recovery, in such a way "that also the second Rieselwerk lye was added. So it was through the previously known facility not possible to purify the air of fine lye particles, as they are in the second Rieselwerk had to enrich it with such again. In contrast, the second trickling plant charged only with water in the invention.

Es ist vorteilhaft, Laugenkühler und Rieselwerk zu einem einzigen Aggregat baulich zu vereinigen, das dadurch möglich gemacht wird, daß das neben dem Kühler angeordnete Rieselwerk nach Wendung der Kühlluft um 18o° durchströmt wird und daß die erforderliche abermalige Wendung um z8o° in einem freiem, gleichfalls baulich vereinigten Nebenraum geschieht.It is advantageous to combine the liquor cooler and trickle system into one To unite aggregate structurally, which is made possible by the fact that the next after turning the cooling air through 180 ° and that the necessary repeated turn around z80 ° in a free, likewise structurally united side room happens.

Die Wendung der Kühlluft um 18o° derart, daß sie nunmehr mit dem reinigenden Wasserregen im Gleichstrom abzieht, hat nicht nur den Vorteil, daß die Nebenkammer mit der Hauptkammer unmittelbar zu einem Stück vereinigt werden kann, sondern auch den, daß Wässer und Kühlluft möglichst lange Zeit in Berührung bleiben, daß also der Reinigungszweck aufs beste erreicht wird.The turning of the cooling air by 180 ° so that it is now with the cleaning Water rain draws off in direct current not only has the advantage that the secondary chamber can be combined directly into one piece with the main chamber, but also that water and cooling air stay in contact for as long as possible, that is the cleaning purpose is achieved in the best possible way.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel wiedergegeben. Der freie Raum a des Kühlers wird von der Kühlluft durchströmt, die durch einen oder mehrere Ventilatoren d eingeblasen wird. Die Lauge wird dem Luftstrom aus Brausen e in feiner Verteilung entgegengeführt. Der Luftstrom wird alsdann in Schwadenform dem Rieselwerk b zugeleitet, welches er im Gleichstrom mit der Waschflüssigkeit durchströmt. Alsdann kehrt der Luftstrom im freien Raum c in die aufwärtige Richtung zurück und verläßt den Laugenkühler am Dach durch Ausströmen ins Freie.In the drawing, the invention is shown in one embodiment. The free space a of the cooler is traversed by the cooling air, which by a or several fans d is blown in. The lye is added to the air flow from showers e countered in fine distribution. The air flow is then in the form of a vapor the trickle works b fed, which he in cocurrent with the washing liquid flows through. Then the air flow in free space c turns in the upward direction back and leaves the caustic cooler on the roof by flowing out into the open.

Die Räume a, b und c sind baulich zu einem einzigen geschlossenen Ganzen vereinigt. Die Strömungsgeschwindigkeit der Luft läßt sich durch den Gang der Ventilatoren nach Bedarf einstellen.The rooms a, b and c are structurally closed to a single one Whole united. The flow speed of the air can be adjusted through the passage adjust the fans as required.
