Description

Bei der Herstellung von; Chlordioxyd ist man bisfer davon ausgegangen, Natriumc'hlorat mit Schwefelsäure oder Oxalsäure zu 'behandeln und durch ein inertes Gas das Chlordioxyd aus diesem Gemisch auszutreiben. Bei'-diesem Verfahren entsteht jedoch explosives Chlordioxyd und die damit ' verbundenen Nachteile haben dazu geführt, daß man in folgender Weise .gearbeitet hat: Natriumchlorit (NaC10Q) wird mit einer Mischung behandelt, die aus Natriumhypochlorit und Schwefelsäure hergestellt ist. Wenn man dieses Verfahren zugrunde legt, so ist man jedoch an drei Komponenten gebunden.In the production of; Chlorine dioxide has until now been assumed Sodium chlorate to be treated with sulfuric acid or oxalic acid and replaced by an inert Gas to expel the chlorine dioxide from this mixture. In this process arises however, explosive chlorine dioxide and the disadvantages associated with it have led to that one has worked in the following way: Sodium chlorite (NaC10Q) is mixed with a Treated mixture made from sodium hypochlorite and sulfuric acid. Using this procedure as a basis, however, is tied to three components.

Der Herstellung der Chlordioxydlösung@ aus Natriumchlorit und Chlorwasser hat nach den bisherigen Ergebnissen eine komplizierte Apparatur erfordert, einen Reaktionsturm mit Füllringen und zeitlich genaue Einhaltung von Temperatur und Konzentrationsbedingungen.The production of the chlorine dioxide solution @ from sodium chlorite and chlorine water has required a complicated apparatus according to the results so far, a Reaction tower with filling rings and precise adherence to temperature and concentration conditions.

>Überraschenderweise ist festgestellt worden, daß bei der Vermischung von Natriumchlorit und Chlorwasser die Herstellung des Ohlordioxyds in einfachster Weise dadurch gelingt, daß man die beiden Stoffe in wäßriger Lösung mittels einer besonderen Mischeinrichtung direkt in Berührung bringt.- Diese Mischeinrichtung besteht in einem Mischglas mit Injektor, in welches im Gegenstrom zum Chlor die Natriumchloritlösung eingepumpt wird (siehe-hierzu Beispiel i in der Zeichnung).> Surprisingly, it has been found that when mixed From sodium chlorite and chlorinated water, the production of carbon dioxide in the simplest possible way Way succeeds in that one of the two substances in aqueous solution by means of a brings special mixing device into direct contact - this mixing device consists of a mixing glass with an injector in which the Sodium chlorite solution is pumped in (see example i in the drawing).

Der Verfahren geht davon aus, daß man Chlor aus einer Flasche a durch eine Meßvorrichtung b zum Mischglas c strömen läßt. Im Mischglas c befindet sich die Mischvorrichtung d, die durch die Wasserarmatur e mit Wasser versorgt wird. Per Mischvorrichtung strömt weiter über die Dosierpumpe g das im Vorratsbehälter aufgespeicherte Natriumchlorit als-Lösung zu.The method assumes that you get chlorine from a bottle a through allows a measuring device b to flow to the mixing glass c. In the mixing glass c is located the mixing device d, which is supplied with water by the water fitting e. The mixing device continues to flow through the metering pump g in the storage container stored sodium chlorite as a solution too.

Auch läBt sich die Vermischung beider Stoffe in einem Injektor durchführen, den man mit Chlorwasser zu betreiben hat (siehe hierzu Beispiel 2 a und 2b in der Zeichnung).The two substances can also be mixed in one injector, which one has to operate with chlorinated water (see example 2 a and 2b in the Drawing).

Diese Ausführungsform benutzt einen Vorratsbehälter f für das N atriumchlorit, das einem Behälter h mit Schwimmer zuläuft, um ein konstantes Niveau zu erreichen. Die Einstellung erfolgt mit einem Ventil und ist ablesbar an der Meßvorrichtung i. Die abgemessene Natriumchloritlösung läuft direkt dem Injektor k zu, der mit Chlorwasser von bestimmter Konzentration versorgt wird.This embodiment uses a storage container f for the sodium chlorite, which runs towards a container h with a float in order to achieve a constant level. The setting is made with a valve and can be read on the measuring device i. The measured sodium chlorite solution runs directly to the injector k, which is with Chlorinated water of a certain concentration is supplied.
