Abstract

It is known to use the heat contents of the mine water for energy purposes. In a further development of this idea, it is proposed according to the invention to use the heat which occurs when the air is cooled in the heat exchangers. It is expedient for this to be done such that the mine heat is cooled decentrally via heat exchangers, and the coolant is conveyed via the liquid as far as the vicinity of the shaft and is exchanged there once more in order to render the carrier medium gaseous so as then to be made available above ground through its own lift (buoyancy) for the purpose as a liquid after being re-exchanged of generating kinetic energy in order to operate a liquid turbine. A considerable saving of energy is achieved due to the fact that the heat of exchange incident in the underground cooling system is re-exchanged in an underground circuit and is brought above ground without additional outlay of energy via an evaporated carrier medium.

Description

Es ist bekannt, daß auch die Wärmeinhalte des Gruben­ wassers im Sinne der Erfindung genutzt werden können.It is known that the heat content of the pits water can be used in the sense of the invention.

Erfindungsgemäß wird nun vorgeschlagen, die Wärme, die beim Kühlen der Wetter in den Wärmetauschern an­ fällt, zu nutzen. Das geschieht zweckmäßigerweise so, daß durch den Verdampfungsprozeß des erfindungsgemäßen Energieträgers Wasser auf eine Temperatur von etwa 3-6°C heruntergekühlt wird, dieses Wasser den einzel­ nen Wärmetauschern zufließt und in diesen auf 24-26°C unter gleichzeitiger Kühlung der Wetter erwärmt wird. According to the invention, the heat, which when cooling the weather in the heat exchangers falls to use. This is conveniently done that by the evaporation process of the invention Energy water to a temperature of about 3-6 ° C is cooled down, this water the single NEN heat exchangers flows and in these to 24-26 ° C. the weather is warmed while cooling.  

Der Wärmeinhalt des rücklaufenden Wassers wird nunmehr erneut dem Verdampfer zugeführt und wieder gekühlt.The heat content of the returning water is now fed back to the evaporator and cooled again.

Ein weiterer erfindungsgemäßer Gedanke besteht darin, daß durch diese Kreislaufprozesse das Kühlwasser zum Kühlen der Grubenbaue in einem untertägigen Kreislauf verbleibt und nicht nach Übertage abgefördert werden muß bzw. ein zweiter Wasserkühlkreislauf im Schacht erübrigt und damit erhebliche Energie gespart wird.Another idea according to the invention is that through these circulatory processes the cooling water to Cooling the mines in an underground circuit remains and cannot be removed after the surface or a second water cooling circuit in the shaft superfluous and thus considerable energy is saved.
