Description
Einrichtung zum Ablassen des Druckes aus Behältern, die mit siedender Flüssigkeit gefüllt sind. öffnet man das Ventil in der Dampfleitung eines mit siedender Flüssigkeit nahezu gefüllten Kessels, so beobachtet man ein Abfallen der Dampfspannung. Gleichzeitig wird im Innern des Kessels in der ersten Zeit nach der Ventilöffnung der Wasserinhalt lebhaft aufschäumen; es wird unter Umständen Wasser mit in die Leitung gerissen. Nach einiger Zeit beruhigt sich der Wasserspiegel, und -es bedarf von diesem Zeitpunkt ab einer verhältnismäßig sehr langen Zeit, bis der Dampfdruck der Außenluft bzw; bis die Temperatur des Wassers auf loo° herabgesunken ist. Diese Verhältnisse werden. um so ungünstiger, je länger und enger die Rohrleitung ist, die den Abdampf an seine Verwendungsrstelle z. B. zur Anwärmung von Kesselspelsewasser leitet. Der Abdampfvorgang kann sich nur dann unter kürzestem Zeitaufwand vollziehen, wenn dafür gesorgt wird, daß die Geschwindigkeit, mit der sich der Dampf aus dem Wasserspiegel erhebt, während des ganzen Verdampfungsvorganges gleichmäßig hoch bleibt.Device for releasing the pressure from containers with boiling Liquid are filled. you open the valve in the steam line of one with boiling When the vessel is almost full of liquid, a drop in vapor tension is observed. At the same time, it is inside the boiler for the first time after the valve has been opened the water content foams vigorously; there may be water in the Line torn. After a while the water level calms down, and it needs to be from this point onwards from one for a relatively long time, until the vapor pressure of the outside air or; until the temperature of the water dropped to 100 degrees is. These ratios will. the more unfavorable, the longer and narrower the pipeline is that the exhaust steam to its user site z. B. for heating boiler flush water directs. The evaporation process can only take place in the shortest possible time, if care is taken that the speed at which the steam leaves the Water level rises, evenly high during the entire evaporation process remain.
Es wurde nun gefunden, daß diese Nachteile auf einfache Weise vermieden werden können, wenn man das Dampfabgangsrohr so bemißt, daß in demselben kein beträchtlicher Druckabfall während der Strömung des Dampfes auftritt. Dies wird mit Vorteil dadurch erreicht, daß man am Ende der Abdampfleitmg kurz vor der Verbrauchsstelle eine Abdrosselung der Rohrleitung zweckmäßig in Form einer Drosselscheibe vorsieht, die so bemessen wird, d.aß die Dampfgeschwin'-digkeit auf dem Wasserspiegel und in der Abdampfrohrleitung die gewollte Größe nicht überschreitet.It has now been found that these disadvantages can be avoided in a simple manner if the steam outlet pipe is dimensioned in such a way that there is no considerable amount in it Pressure drop occurs during the flow of steam. This is beneficial because of this achieves that at the end of the Abdampfleitmg shortly before the point of consumption a throttling the pipeline is expediently provided in the form of a throttle disc which is dimensioned in this way is, i.e. the steam speed on the water level and in the exhaust pipe does not exceed the desired size.
Die Erfindung ist auf der Zeichnung näher veranschaulicht.The invention is illustrated in more detail in the drawing.
In die Dampfleitung a des mit siedender Flüssigkeit gefüllt-en Kessels b ist eine. Drosselsch-eibe c nahe an der Verbrauchsstelle des Dampfes, z. B. eines Speisewasserbehälters, eingebaut. Das Ventile kann bei richtiger Bemessung von c vollkommen geöffnet werden, ohne daß Gefahr für Überschäumen des Kesselinhalts besteht.In the steam line a of the boiler filled with boiling liquid b is a. Throttle disc c close to the point of consumption of the steam, e.g. B. one Feed water tank, built-in. With the correct dimensioning of c can be opened completely without the risk of the contents of the kettle foaming over.
