Description

Herstellung von Chlorkalk in Etagenapparaten. Es ist bekannt, Chlorkalk in mit Rührwerk ausgestatteten Etagenapparaten herzustellen, denen gelöschter Kalk oben zugeführt wird, während das Chlorgas unten eingeleitet wird und sich im Gegenstrom zu dem von Etage zu Etage abwärts wandernden Kalk be-tvegt.Production of chlorinated lime in floor units. It is known to be chlorinated lime produce in multi-storey units equipped with agitators, which slaked lime is fed in at the top, while the chlorine gas is fed in at the bottom and is in countercurrent to the lime moving down from floor to floor.

Zweck derartiger Apparate ist, J eine bessere Regulierung der Reaktionstemperatur zu erreichen, und zwar insbesondere derart, daß die letzte Stufe der Reaktion, bei der das Chlorgas auf Stoffe einwirkt, die bereits bedeutende :Mengen an bleichendem Chlor enthalten, langsam verläuft, so daß die mit der Bindung des Chlorgases verknüpfte Wärmeentwicklung eine erhebliche Temperaturerhöhung im Produkt nicht bewirkt.The purpose of such apparatus is to better regulate the reaction temperature to achieve, in particular in such a way that the last stage of the reaction, at the chlorine gas acts on substances that are already significant: amounts of bleaching Contain chlorine, proceeds slowly, so that the linked with the binding of the chlorine gas The development of heat does not cause a significant increase in temperature in the product.

Um die Temperatur auf den verschiedenen Etagen des Apparates auf der zweckmäßigsten Höhe zu erhalten ist vorgeschlagen worden, die Etagenböden doppelwandig auszuführen und sie durch Wasser zu kühlen.To keep the temperature on the different floors of the apparatus on the To obtain the most appropriate height has been proposed to double-walled the floors and to cool them with water.

Es hat sich indessen herausgestellt, daß selbst bei Anwendung gekühlter Etagenböden die vollständige Beherrschung der Temperatur mit recht großen Schwierigkeiten verknüpft ist, so daß der Fall leicht eintritt, daß die Reaktion mit zu großer Geschwindigkeit verläuft und infolgedessen eine derartige Temperaturerhöhung eintritt, daß der fertige Chlorkalk nicht den Höchstgehalt an bleichendem Chlor enthält, weil bei der zu hohen Temperatur Nebenreaktionen eintreten. Besonders ungünstig kommen diese Verhältnisse zur Geltung, wenn man die Etagenapparate in großen Einheiten, also mit einer großen Produktionskapazität auf den Apparat anwenden will, was natürlich an sich technisch das vorteilhafteste wäre.It has been found, however, that even when using cooled Floor floors the complete control of the temperature with quite a lot of difficulty is linked, so that it is easy to occur that the reaction is too rapid runs and as a result such a temperature increase occurs that the finished Chlorinated lime does not contain the maximum level of bleaching chlorine because it is too high Temperature side reactions occur. These conditions are particularly unfavorable comes into its own when you use the floor units in large units, i.e. with a large one I want to apply production capacity to the apparatus, which of course is technical in itself would be the most beneficial.

Die Erfindmig bezweckt, eine Regelung der Temperatur insbesondere auch bei großen Einheiten der Etagenapparate zu - erreichen und besteht darin, daß das Chlorgas bzw. das chlorhaltige Gasgemisch zur Kühlung der Reaktionsmasse benutzt wird, und zwar in der Weise, daß das Gas in Umlauf geleitet und dabei gekühlt wird. Das Chlorgas wird dem Apparate entnommen, und zwar vorzugsweise auf denjenigen Etagen, wo die Absorption am lebhaftesten ist, und die Temperatur deshalb am leichtesten zu hoch steigt, wird durch eine an oder neben dem Apparat angeordnete geeignete Kühlvorrichtung geführt und darauf in gekühltem Zustande in den Apparat zurückgeleitet, wobei das Einleiten entweder auf derselben oder auf einer höher oder niedriger gelegenen Etage stattfinden kann. Zur Bewegung des Gases in der Umlaufsleitung ist zwischen dem Apparat und der Kühlvorrichtung ein Zentrifugalventilator o. dgl. angeordnet.The aim of the invention is to regulate the temperature in particular even with large units of the floor units - to achieve and consists in that the chlorine gas or the chlorine-containing gas mixture is used to cool the reaction mass in such a way that the gas is circulated and thereby cooled. The chlorine gas is taken from the apparatus, preferably on those floors where the absorption is most vivacious, and therefore the temperature easiest rises too high is indicated by a suitable one placed on or next to the apparatus Cooling device guided and then fed back into the apparatus in a cooled state, the initiation either on the same or on a higher or lower level Floor can take place. To move the gas in the circulation line is between A centrifugal fan or the like is arranged in the apparatus and the cooling device.

Der Umlauf des Gases kann gegebenenfalls mit seiner Trocknung verbunden werden. Es ist wohl bekannt, daß, um ein hochwertiges Chlorkalkproduktzu erzeugen, es von Bedeutung ist, daß das Chlorgas und der Kalk den richtigen Feuchtigkeitsgrad besitzen. Gemäß der Erfindung erreicht man eine Regelung der Feuchtigkeit dadurch, daß das umlaufende Chlorgas mehr oder weniger getrocknet wird.The circulation of the gas can optionally be combined with its drying will. It is well known that in order to produce a high quality chlorinated lime product, it is important that the chlorine gas and lime have the correct degree of humidity own. According to the invention one achieves a regulation of the humidity in that the circulating chlorine gas is more or less dried.
