Description
Vorrichtung zum Ablassen des. hohen Salzgehalt besitzenden Wassers aus Elektrodendampfkesseln Die Erfindung betrifft eine Vorrichtung zum Ablassen des hohen Salzgehalt besitzenden Wassers aus Elektrodendampfkesseln, bei denen die Leistungsaufnahme durch Verändern des Wasserstandes geregelt wird.Device for draining the high salinity water from electrode steam boilers The invention relates to a device for draining of the high salt content of water from electrode boilers, where the Power consumption is regulated by changing the water level.
Die Leitfähigkeit des Wassers im Elektrodendampfkessel hängt bekanntlich von der relativen Menge der im Kesselwasser gelösten Salze ab. Um die Leitfähigkeit des Kesselwassers auf einem konstanten Wert zu halten, ist es -erforderlich, daß derjenige Teil des eingedampften Kesselwassers, der die höchste Salzkonzentration besitzt, abgelassen wird.As is well known, the conductivity of the water in the electrode steam boiler depends on the relative amount of the salts dissolved in the boiler water. To the conductivity To keep the boiler water at a constant value, it is necessary that that part of the evaporated boiler water that has the highest salt concentration owns, is drained.
Nun ist die Salzkonzentration in den obersten Wasserschichten, in denen die größte Dampferzeugung stattfindet, am größten. Es ist daher bereits vorgeschlagen worden, die abzuführende Kesselwassermenge den Wasserschichten zu ientnehmen, in denen die Verdampfung stattfindet, und zwar durch Rohre, die bis zum höchsten Wasserstand reichen und in der Verdampfungszone mit Durchbrechungen versehen sind.Now the salt concentration is in the uppermost water layers, in those with the greatest steam generation, the greatest. It is therefore already proposed have been to take the amount of boiler water to be discharged from the water layers, in where the evaporation takes place, through pipes that lead up to the highest water level and are provided with perforations in the evaporation zone.
Bei solchen Elektrodendampfkesseln, deren Leistungsaufnahme durch Verändern des Wasserstandes geregelt wird, müßten diese Öffnungen vom höchsten Wasserstand bis unter den tiefsten Wasserstand reichen, damit auch beim Arbeiten mit kleinster Leistung und niedrigstem Wasserstand die nötige Menge Kesselwasser abgelassen werden kann. Hierbei würde aber nicht zu vermeiden sein, daß bei höheren Wasserständen durch das Rohr zuviel Wasser, das noch gar nicht eine unzulässig hohe Salzkonzentration aufweist, aus den dem niedrigsten Wasserstand benachbarten Wasserschichten entnommen wird. Es würde auch nicht viel helfen, die Größe der Durchbrechungen des Ablaufrohres von oben nach unten hin abzustufen, weil dann immer noch zuviel Wasser geringer Salzkonzentration mit ablaufen würde. Durch das Ablassen von zu großen Wassermengen .ergeben sich aber unnötige Wärmeverluste und daher eine Verschlechterung des Wirkungsgrades des Kessels.In such electrode boilers, their power consumption is reduced by Changing the water level is regulated, these openings should be from the highest water level reach below the lowest water level, so even when working with the smallest Power and lowest water level, the required amount of boiler water can be drained can. Here, however, it would not be possible to avoid that at higher water levels Too much water through the pipe, which does not have an inadmissibly high salt concentration has, taken from the water layers adjacent to the lowest water level will. It wouldn't help much either, the size of the openings in the drainpipe to graduate from top to bottom, because then there is still too much water less Salt concentration would expire with. By draining too much water .but there are unnecessary heat losses and therefore a deterioration in efficiency of the boiler.
Die Erfindung bezweckt, alle diese Nachbeile zu vermeiden. Dieser Zweck wird gemäß der Erfindung bei einer Vorrichtung zum Ablassen .des hohen Salzgehalt besitzenden Wassers aus Elektrodendampfkesseln, deren Leistung durch Verändern des Wasserstandes geregelt wird, 4ttels eines in den Wasserraum des Kessels hineinragenden und mit Durchbrechungen in verschiedener Höhenlage versehenen Ablaufrohres dadurch erreicht, daß -ein das öffnen und Schließen der Durchbrechungen überwachender Schieber angeordnet ist, dessen. Stellung sich in Abhängigkeit vom Wasserstande so ändert, daß die zum Ablauf bestimmte Kesselwassermenge immer nur den jeweils obersten Wasserschichten entnommen wird. Dies kann beispielsweise dadurch bewirkt werden, daß ein in den Wasserraum des Elektrodendampfkessels hin-. einragendes, mit Durchbrechungen versghenes Ablaufrohr mit einem beispielsweise rohrförmigen Schieber zusammenwirkt, der von Schwimmern getragen wird, die den rohrförmigen Schieber mit ansteigendem Wasserstand in seine Höhenlage schieben. Die Größe der Durchbrechungen des Ablaufrohres nimmt zweckmäßig von oben nach unten ab. Bei jedem Wasserstand kann demzufolge das Kesselwasser nur aus den dem jeweiligen Wasserstand benachbarten Wasserschichten ,entnommen werden.The invention aims to avoid all of these disadvantages. This The purpose is according to the invention in a device for draining .the high salt content owning water from electrode boilers, whose output can be changed by changing the Water level is regulated, 4ttels a protruding into the water space of the boiler and drainage pipe provided with openings at different heights through it achieves that -a slide monitoring the opening and closing of the openings is arranged, whose. The position changes depending on the water level, that the amount of boiler water determined for the drain is always only for the uppermost water layers taken will. This can be achieved, for example, by inserting into the water space of the electrode steam boiler. protruding drain pipe with perforations cooperates with, for example, a tubular slide that is used by floats is carried, which the tubular slide with rising water level in his Push high altitude. The size of the openings in the drain pipe increases appropriately from top to bottom. At every water level, the boiler water can only can be taken from the water layers adjacent to the respective water level.
