Description

Regelung des Kalkgehalts von Sulfitlaugen In dem Hauptpatent wird ein Verfahren zur Regelung des Kalkgehalts der Sulfitlauge unter Schutz gestellt, bei dem die erforderliche tiefe Temperatur dadurch erreicht wird, daß das Berieselungswasser für den Laugenturm mit Hilfe eines besonderen Kälteerzeugers herabgekühlt wird. Eine gleiche Wirkung läßt sich nun in der Weise erreichen, daß man die Kocherabgase, die in den Turm eingeleitet werden, vorher mit Hilfe einer Kälteerzaugungsanlage so weit herabkühlt, daß die gewünschte Temperatur in dem Laugenturm erreicht wird. Praktisch arbeitet man in der Weise, daß man die Gase zunächst durch verschiedene mit Fluß- oder Grundwasser betriebene Kühler leitet und anschließend daran durch einen Soleküh.ler schickt. Die Sole wird mit Hilfe einer besonderen Kältemaschine dauernd auf hinreichend niedriger Temperatur gehalten. Die gekühlten Abgase werden in den Laugenturm eingeleitet, der mit Wasser berieselt wird und dessen Temperatur der normalen Außentemperatur entspricht.Regulation of the lime content of sulphite liquors In the main patent a process for regulating the lime content of the sulphite liquor has been placed under protection, at which the required low temperature is achieved by the sprinkling water for the liquor tower is cooled down with the help of a special cold generator. The same effect can now be achieved in such a way that the stove exhaust gases, which are introduced into the tower, beforehand with the help of a refrigeration ventilation system cools down so far that the desired temperature is reached in the liquor tower. In practice one works in such a way that the gases are first passed through different with river or groundwater operated cooler passes and then through it sends a brine heater. The brine is made with the help of a special cooling machine kept at a sufficiently low temperature at all times. The exhaust gases are cooled introduced into the liquor tower, which is sprinkled with water and its temperature corresponds to the normal outside temperature.
