Description
Flüssigkeit zur Aufnahme, Übertragung und Aufspeicherung von Wärme. Die Hauptschwierigkeit für die Fernüber tragung .von Wärme, von einem Generator nach einer Verbrauchsstelle, bestand bis jetzt :darin, Wärmeträger zu finden, welche imstande sind, ohne Dampfbildung und ohne Zersetzung, * grosse Wärmemengen aufzu nehmen.
Eine bekannte Art der Wärmeaufspeiche- rung und der Wärmeübertragung besteht darin, dass ein ganz- oder teilweise mit Was ser .gefülltes Rohrsystem mit Kohle oder irgend einem andern Heizmittel geheizt wird.
Für niedrige Temperaturen und kleinere Wärmemengen hat die vorbeschriebene Art der Wärmeaufspeicherung und W-irmeüber- tragung mittelst Wasser befriedigende Re sultate ergeben.
Handelt es sich jedoch darum, grosse Wärmemengen bei hohen Temperaturen .auf zuspeichern, so eignet sich Wasserfüllung nicht mehr, da Wasser sclhon bei verhältnis mässig niedriger Temperatur siedet und ge fährlich hohe Drucke auftreten, welche die Betriebssicherheit der Anlage in hohem Masse gefährden. Der Zweck vorliegender Erfindung ist, die geschilderten Nachteile der Wasserfül lung zu -vermeiden.
Zur Aufnahme, Über tragung und Aufspeicherung von Wärme dient ;gemäss der Erfindung eine Flüssigkeit, die aliphatische, gesättigte Kohlenwasser stoffe, die frei von. bei 0 C nicht mehr flüs sigen Paraffinen sind und deren Siedepunkt nicht unter<B>170'</B> C liegt, enthält. Ungesät tigte Verbindungen, sowie andere Begleit- stoffe des Ausgangsmaterials werden zweck mässig durch eine Schwefelsäure-Laugen- rein,igung entfernt.
Eisen und Metalle werden von dieser Niederdruckfüllung in keiner Weise ange griffen.
Ein; Hauptvorzug des Erfindungsgegen standes besteht darin, dass bei einer Erliit- zung in geschlossenem Gefäss bis .auf zirka 2.00 bis 220' C sich bei Anwendung von zum Beispiel Erdöl, noch keinerlei Druck ergibt, bei einer Dauererhitzung his auf<B>350'</B> C be trägt derselbe nur zirka 5 bis 6 Atmosphären.
Liquid for absorbing, transferring and storing heat. The main difficulty for the remote transmission of heat, from a generator to a point of consumption, has until now been: to find heat carriers which are capable of absorbing large amounts of heat without the formation of steam and without decomposition.
A known type of heat storage and heat transfer consists in heating a pipe system, which is completely or partially filled with water, with coal or some other heating medium.
For low temperatures and smaller amounts of heat, the type of heat storage and heat transfer described above using water has given satisfactory results.
However, if it is a question of storing large amounts of heat at high temperatures, water filling is no longer suitable, since water boils at a relatively low temperature and dangerously high pressures occur, which endanger the operational safety of the system to a great extent. The purpose of the present invention is to avoid the disadvantages of water filling described above.
Serves to absorb, transfer and store heat; according to the invention, a liquid that contains aliphatic, saturated hydrocarbons that are free from. at 0 C are no longer liquid paraffins and whose boiling point is not below <B> 170 '</B> C. Unsaturated compounds and other accompanying substances in the starting material are expediently removed by cleaning with sulfuric acid and lye.
Iron and metals are in no way attacked by this low-pressure filling.
One; The main advantage of the subject matter of the invention is that if it is heated in a closed vessel to about 2.00 to 220 ° C when using, for example, petroleum, there is still no pressure whatsoever. B> C it is only about 5 to 6 atmospheres.
