Description

Einrichtung zur selbsttätigen Konstanthaltung der Strömungsgeschwindigkeit bei Entnahme von Chlorgas aus einerü mit Flüssigchlor gefüllten Behälter Es ist bekannt, daß bei Entnahme von Chlorgas aus einem mit Flüssigchlor gefüllten Behälter, z. B. Stahlflasche, die Strömungsgeschwindigkeit bei unveränderter Ventilstellung abnimmt, so daß man zur Erzielung zeitlich konstanter -Entnahmen das Regelventil häufig . nachstellen muß. Der Grund hierfür liegt in dem Druckabfall innerhalb des Chlorbehälters, der seinerseits durch die Abkühlung bedingt ist, die das flüssige Chlor zufolge Entzuges der Verdampfungswärrne erleidet. Man hat sich in solchen Fällen auch dadurch geholfen, daß man entweder einen Chlorvorratsbehälter wählte, dessen Inhalt an Flüssigchlor sehr groß ist im Vergleich zu den entnommenen :Mengen, oder indem.man den Behälter erwärmte, z. B. durch Berieseln mit warmem Wasser oder Einstellen in ein Warmwasserbad. Diese Maßnahmen haben aber keine regelnde Wirkung. Dagegen erwies sich die Verwendung eines ' Recluzierventils üblicher Bauart als unbefriedigend, weil die bekannten Ventile dieser Ar[ dem Angriff durch das Chlor auf die Dauer nicht standhalten.Device for automatically keeping the flow rate constant when removing chlorine gas from a container filled with liquid chlorine It is known that when chlorine gas is withdrawn from a container filled with liquid chlorine, z. B. steel bottle, the flow rate with unchanged valve position decreases, so that the control valve is used to achieve constant withdrawals over time frequently . must readjust. The reason for this lies in the pressure drop within the Chlorine tank, which in turn is conditioned by the cooling that the liquid Due to chlorine, the heat of evaporation is withdrawn. One has oneself in such Cases also helped by choosing either a chlorine storage tank, whose content of liquid chlorine is very large compared to the extracted: amounts, or by heating the container, e.g. B. by sprinkling with warm water or Setting in a warm water bath. However, these measures have no regulating effect. In contrast, the use of a 'Recluzierventils conventional design proved to be unsatisfactory, because the known valves of this ar [attack by the chlorine not withstand in the long run.

Die Einrichtung gemäß der vorliegenden Erfindung löst nun die Aufgabe der selbsttätigen Konstanthaltung der Strömungsgeschwindigkeit bei Entnahme von Chlorgas aus dein Chlordruckbehälter in der Weise, daß in die unter Behälterdruck stehende Abzugsleitung ein Kontaktthermometer eingebaut ist, das gegebenenfalls über einen Kraftschalter den Heizstromkreis für einen das Flüssigchlor erwärmenden Heizkörper steuert. Es genügt hierbei, daß lediglich jener Teil des Druckbehälters vom Heizkörper entweder unmittelbar oder mittelbar, z. B. durch ein Wasserbad, erwärmt wird, in dein sich das Flüssigchlor befindet.The device according to the present invention now solves the problem the automatic maintenance of the flow velocity when removing Chlorine gas from your chlorine pressure tank in such a way that in the under tank pressure a contact thermometer is installed, which can be used if necessary The heating circuit for one that heats the liquid chlorine via a power switch Radiator controls. It is sufficient here that only that part of the pressure vessel from the radiator either directly or indirectly, e.g. B. heated by a water bath which contains the liquid chlorine.

Gewünschtenfalls kann in diesem Wasserbad ein Kontaktthermometer angeordnet sein, das den Heizstromkreis unterbricht, wenn c eine vorbestimmte Höchsttemperatur im Wasserbad überschritten wird. Dein gleichen Zweck kann auch ein Sperrschalter dienen, der den Heizstromkreis dann unterbricht, wenn das Feinregelventil in der Chlorabzugsleitung geschlossen ist.If desired, a contact thermometer can be arranged in this water bath be that interrupts the heating circuit when c a predetermined maximum temperature is exceeded in the water bath. A lock switch can serve the same purpose serve, which then interrupts the heating circuit when the precision control valve in the Chlorine discharge line is closed.

Die Einrichtung gemäß der Erfindung ist auch für Druckbehälter mit anderen aggressiven Gasen geeignet. Durch Beobachtung der Wasserbadtempexatur ist ferner in einfacher Weise eine Schätzung des Inhalts des Behälters an Flüssigchlor möglich. In der Zeichnung ist die Einrichtung gemäß der Erfindung schematisch dargestellt. cr bezeichnet eine Chlorflasche üblicl Bauart, b das Absperrventil, C ein Feinre ventil, das gegebenenfalls auch durch wechselbare Drosselscheiben ersetzbar d ein in die Verbindungsleitung zwischen Ab-Sperrventil und Feinregelventil eingebautes Kontaktthermometer üblicher Bauart, dessen einer Kontakt vorzugsweise einstellbar ist und dessen Quecksilberkugel zweckmäßig in einem mit Paraffinöl gefüllten Metallbehälter angeordnet ist. e bezeichnet einen vom Kontaktthermometer gesteuerten elektrischen aftschalter, f den vom Kraftschalter ge- erten Heizkörper, z. B. elektrischen Heiz- t, der in einen mit Wasser gefüllten Bad- iälter g hineinragt, Der Badbehälter g umgibt lediglich den unteren Teil der Chlorflasche a.The device according to the invention is also suitable for pressure vessels with other aggressive gases. By observing the water bath temperature, it is also possible to estimate the liquid chlorine content of the container in a simple manner. In the drawing, the device according to the invention is shown schematically. cr usually denotes a chlorine bottle Type, b the shut-off valve, C a Feinre valve, which may also be through exchangeable orifice plates can be replaced d a contact thermometer of conventional design built into the connecting line between the shut-off valve and precision control valve, one contact of which is preferably adjustable and the mercury ball of which is expediently arranged in a metal container filled with paraffin oil. e denotes an electrical switch controlled by the contact thermometer, f the switch controlled by the erten radiators, e.g. B. electric heating t, which is in a bath filled with water Older g protrudes, the bath tank g surrounds only the lower part of the chlorine bottle a.
