Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Wärmeüber tragung zwischen flüssigen Medien einerseits und ebenfalls flüssigen Medien oder festen Körpern andererseits.The invention relates to a method for heat transfer transfer between liquid media on the one hand and also liquid media or solid bodies on the other hand.
Bei Verfahren zur Wärmeübertragung dieser Art ergibt sich häufig die Schwierigkeit, besonders dann wenn die Wärmeüber tragung verhältnismäßig langsam vor sich gehen soll, die Wärmeübertragung mit einer vorgegebenen, sich für den Über tragungsprozeß nicht ändernden Wärmeübertragungszahl durch zuführen, oder auch die Wärmeübertragung unter gesteuerter Änderung der Wärmeübertragungszahl vorzunehmen.In heat transfer processes of this type, this results often the difficulty, especially when the heat is over should proceed relatively slowly, the Heat transfer with a predetermined, for the over Wear process not changing heat transfer through supply, or even the heat transfer under controlled Make a change in the heat transfer number.
Der Erfindung liegt die Aufgabe zugrunde eine solche Möglichkeit mit verhältnismäßig geringem technischen Aufwand zu schaffen.The invention is based on the object of such a possibility to create with relatively little technical effort.
Diese Aufgabe wird dadurch gelöst, daß ein das flüssige Medium aufnehmender Behälter oder eine Leitungsführung für das strö mende flüssige Medium bzw. der feste Körper allseitig von einem strömend geführten flüssigen Medium beaufschlagt werden, dem ständig ein vorgegebener Anteil eines gasförmigen Mediums zu gemischt wird. Wie die Erfindung weiter vorsieht kann als flüssiges Medium Wasser und als zuzumischendes gasförmiges Medium vorteilhaft Luft verwendet werden. Es besteht ferner die Mög lichkeit, den Druck des strömend geführten Mediums veränder- und festlegbar zu machen oder auch, soweit die Wärmeübertragung auf einen festen Körper erfolgen soll, diesen mit veränder barer und festlegbarer Geschwindigkeit zu bewegen. This object is achieved in that the liquid medium receiving container or a conduit for the stream liquid medium or the solid body on all sides of one flowing fluid medium are applied, the constantly a predetermined proportion of a gaseous medium is mixed. How the invention further provides as liquid medium water and as a gaseous medium to be mixed air can be used advantageously. There is also the possibility ability to change the pressure of the flowing medium and to make it determinable or as far as the heat transfer on a solid body, change it moveable and definable speed.
Als Vorrichtung zur Durchführung dieser Verfahren eignet sich ein zylindrisches äußeres Rohr, das koaxial ein das strömend geführte Medium aufnehmendes inneres Zylinderrohr umfaßt. Dabei wird zweckmäßig am offenen Eingang des äußeren Zylinderrohres ein Düsenkopf angeordnet, dem das flüssig strömende Medium zuführbar ist, und der ein in ihm axial verschiebbares Einlauf rohr aufweist mit dem zusammen der Düsenkopf eine das innere Zylinderrohr umfassende Ringdüse für den Austritt des flüssigen Mediums bei gleichzeitigem Ansaugen des gasförmigen Mediums durch den offenen Eingang des äußeren Zylinderrohres bilden.A suitable device for carrying out these methods a cylindrical outer tube that coaxially flows guided medium receiving inner cylinder tube. Here is useful at the open entrance of the outer cylinder tube a nozzle head arranged, the liquid flowing medium can be fed, and an inlet axially displaceable in it Pipe with which the nozzle head has an interior Ring nozzle comprising a cylindrical tube for the exit of the liquid Medium with simultaneous suction of the gaseous medium through the open entrance of the outer cylinder tube.
Das Verfahren kann dabei so abgewickelt werden, daß z.B. Wasser in den Düsenkopf eingebracht wird und aus der von Düsenkopf und Einlaufrohr gebildeten Ringdüse austritt der hinter dem Austritts querschnitt der so gebildeten Düse entstehende Unterdruck saugt dabei in bekannter Weise Luft aus dem offenen Eingang des äußeren Zylinderrohres an, so daß hinter der Düse ein Wasser-Luft-Gemisch entsteht, dessen Zusammensetzung durch Axialverschiebung des Ein laufrohres in weiten Grenzen geändert werden kann. Das Wasser- Luft-Gemisch beaufschlagt auf seinem weiteren Weg durch das äußere Zylinderrohr allseitig das innere Zylinderrohr, in dem das flüssige Medium geführt ist, das entweder Wärme aufnehmen oder ab geben soll. Anstelle dieses inneren Zylinderrohres kann auch unmittelbar durch die Mitte des äußeren Zylinderrohres ein stab förmiger fester Körper z.B. in Drahtform mit der jeweils ge wünschten Geschwindigkeit bewegt werden wobei der Umfang dieses Stabes unmittelbar von dem Wasser-Luft-Gemisch beaufschlagt wird.The process can be carried out in such a way that e.g. water is introduced into the nozzle head and from that of nozzle head and Inlet tube formed ring nozzle emerges from behind the outlet cross section of the nozzle thus formed sucks vacuum air in the known manner from the open entrance of the outer Cylinder tube so that a water-air mixture behind the nozzle arises, whose composition by axial displacement of the one can be changed within wide limits. The water- Air mixture acts on its way through the outside Cylinder tube on all sides the inner cylinder tube in which the liquid medium is led, which either absorb heat or from should give. Instead of this inner cylinder tube, too a rod directly through the middle of the outer cylinder tube shaped solid body e.g. in wire form with the respective ge desired speed are moved, the extent of this Rod is acted upon directly by the water-air mixture.
Die Vorrichtung läßt sich auch so gestalten, daß sie in ansich be kannter Weise mit Hilfe von Sensoren und Steuereinrichtungen das Einlaufrohr des Düsenkopfes und ggfs. Abströmungsdruck und Stab geschwindigkeit entsprechend aufgrund der Sensor-Meßergebnisse verrechneter Werte steuert.The device can also be designed so that it be in itself knew the way with the help of sensors and control devices Inlet pipe of the nozzle head and, if necessary, discharge pressure and rod speed accordingly based on the sensor measurement results controls calculated values.
